    On many 2.5L QR25DE Altimas, the pre-catalytic converter material can deteriorate and be drawn back into the engine during valve overlap, scoring cylinder walls and accelerating oil consumption. Owners report needing to add oil frequently, loss of compression, rough running, and in severe cases complete engine failure. This issue is widely discussed in owner communities and tied to Nissan service information addressing catalyst and ECM updates on affected 2.5L cars.

    Common Symptoms

    • excessive oil consumption
    • blue exhaust smoke
    • check engine light
    • rough idle
    • loss of power
    • engine knocking
    • failed emissions test

    How to Fix

    Diagnosis usually includes checking oil consumption, compression, catalyst condition, and inspecting for catalyst substrate breakup. Repairs range from replacing the pre-cat/manifold and upstream O2 sensor to replacing the engine if cylinder damage is already present. Owners also commonly verify ECM calibration updates and monitor oil level closely after repair.

    Owner tips & cautions

    • TipIf a 2.5L Altima is using oil, inspect the pre-cat before simply replacing valve cover gaskets or PCV parts; continued driving can turn a catalyst issue into a full engine replacement.
    • TipPerform compression and leak-down testing before authorizing repairs, because many owners found the catalyst was only part of the problem once cylinder scoring had started.
    Typical repair cost:$900 - $4,500

    Nissan Altima models built with the 3-cylinder 1.5L (KR15DDT) or 4-cylinder 2.0L (KR20DDET) variable-compression turbo (VC-Turbo) engine can suffer a manufacturing defect in the engine's bearings (main bearing and the A-, C-, and L-link bearings that are unique to the variable-compression mechanism). The bearings can degrade or break apart, introducing metal debris into the oil and causing progressive internal damage that can result in sudden, complete engine failure. Nissan filed the Part 573 recall report (NHTSA 25V437) on June 26, 2025, after NHTSA's multi-year investigation (PE23023). About 5,685 2019-2020 Altimas are covered, along with related Rogue and Infiniti QX50/QX55 models (~443,899 total).

    Common Symptoms

    • Engine warning/malfunction light
    • Knocking or unusual engine noise
    • Rough running or reduced power
    • Sudden loss of power / engine stall
    • Complete engine failure / vehicle won't run

    How to Fix

    Under recall 25V437, dealers inspect the engine oil and oil pan for metal debris. If debris is found the engine is replaced; if clean, the ECU is reprogrammed/updated to add bearing-protection logic. Nissan is extending the powertrain warranty on the recall population to 10 years / 120,000 miles and reimbursing prior out-of-warranty repairs. Owners notified starting late August 2025. Stop driving and have the car towed if you hear knocking or see a warning light before repair.

    The first-generation-era 2.5L QR25DE (2002-2006) is well known for head gasket failure. Because the QR25 uses an open-deck block, the combustion ring of the gasket commonly fails into the combustion chamber, so owners often see disappearing coolant, overheating, and white exhaust smoke without the classic milky oil. Failures are frequently linked to the pre-catalyst breaking up and scoring cylinders (raising heat/pressure) and to the secondary block thermostat sticking closed. Left unrepaired it leads to chronic overheating and potential warped-head / engine damage.

    Common Symptoms

    • Unexplained coolant loss with no visible puddle
    • Overheating, especially under load
    • White smoke from the exhaust
    • Overflow tank overfilling/bubbling
    • Misfire or rough running from coolant in a cylinder

    How to Fix

    Pressure/combustion-leak test the cooling system to confirm. Repair requires removing the head, inspecting/machining for warpage, and installing a new MLS head gasket set with new head bolts. OEM cylinder head gasket for the 2.5L QR25DE is in the 11044- family (e.g., 11044-8J022 for ~2006, supersedes 11044-8J020/8J010; 11044-6N202 also referenced). Replace the secondary block thermostat while in there and address any pre-cat breakdown. Typical repair runs $1,200-$2,500+.

    On the 3.5L VQ35DE V6 the plastic secondary timing chain guides/tensioner shoes become brittle and break, and the secondary (cam) chain tensioners lose tension. This produces a loud rattle or whine from the front of the engine, most pronounced for the first few seconds of a cold start. When a guide breaks, the chain runs slack and can contact the tensioner piston (the 'death rattle'), risking valve-timing skip and internal damage if ignored. Owners across multiple Altima forums document this as one of the defining VQ35DE problems, and there is a Nissan TSB covering secondary-chain replacement.

    Common Symptoms

    • Loud rattle from front of engine on cold start lasting a few seconds
    • Whining or buzzing noise from timing cover area
    • Rattle that returns and worsens over time
    • Possible check engine light for camshaft/crankshaft correlation if chain skips

    How to Fix

    Diagnose with a cold-start listen plus inspection of the front cover for guide debris. The fix is replacing the secondary timing chains, tensioner shoes/guide rails, and tensioners (and typically the primary chain components and oil seals) as a complete kit while the front cover is off. Per the Nissan secondary-chain TSB, key OEM parts are secondary chains 13028-ZK01C (x2) and tensioner-shoe/guide rails 13097-ZK01C (x2) plus o-rings/seals. Use OEM or quality kits; do all guides, tensioners, and chains together. It is 8-14 hours of labor due to front-cover access.

    P0016 is one of the most well-documented Altima powertrain failures and is a hallmark of the 2.5L QR25DE (it also affects the 3.5L V6). The ECM sets P0016 when the camshaft (Bank 1, Sensor A) and crankshaft signals fall out of their expected relationship. On the Altima this is most often caused by a physically stretched timing chain combined with worn plastic timing-chain guide rails and a failing chain tensioner: as the chain slackens, cam timing drifts and the correlation code sets. A contributing root cause is sludge building up behind the primary drive gear, which starves the tensioner of oil pressure and lets the chain slap. The classic early warning is a rattle from the front of the engine on cold start that worsens over time. Related VVT/correlation codes (P0011/P0021/P0024) often accompany it. If ignored, a jumped chain can cause valve-to-piston contact and catastrophic engine damage.

    Common Symptoms

    • Rattle/tapping from front of engine on cold start
    • Check engine light
    • Rough idle and hesitation
    • Hard starting
    • Reduced power and fuel economy

    How to Fix

    Verify oil level/condition and rule out a sludged tensioner or bad camshaft position sensor first. The accepted repair is a full timing chain service: replace the timing chain, both guide rails, the tensioner, and the VVT/oil-control components as needed, and clean sludge from behind the drive gear. Use correct-viscosity oil and proper change intervals afterward to prevent recurrence.

    The 2.5L PR25DD four-cylinder used in 2019+ Altimas is direct-injection only, so fuel never washes the back of the intake valves. Over time carbon/soot accumulates on the intake valves and on the intake-manifold runner control flaps, causing rough idle, hesitation, reduced power, and reduced fuel economy. On 2019-2020 models in particular, cold weather can cause the intake-manifold runner control to stick and set DTC P2004 (Intake Manifold Runner Control Stuck Open, Bank 1); Nissan's TSB NTB20-083A directs replacement of the intake manifold to resolve the fault. As a GDI engine, the PR25DD generally benefits from periodic intake-valve cleaning (walnut blasting) at higher mileage.

    Common Symptoms

    • Check engine light (P2004)
    • Rough idle
    • Hesitation / loss of power
    • Reduced fuel economy
    • Cold-weather drivability issues

    How to Fix

    For a stored P2004, follow TSB NTB20-083A — typically replacement of the intake manifold assembly (the runner-control flaps/actuator are integral). For general carbon-related rough running, perform a walnut-blast intake-valve cleaning and consider an oil-catch can and use of Top Tier fuel to slow re-accumulation. EGR cleaning may also be needed if idle/stall symptoms persist.

    The 2.5L QR25DE four-cylinder is widely documented for repeated coil-on-plug ignition coil failures, with cylinders 1 and 4 (the end cylinders) failing most often. A failing coil triggers a single-cylinder misfire, rough idle, hesitation, and a flashing check engine light. Failures are frequently accelerated by oil leaking from the valve cover gasket / spark-plug tube seals saturating the coil boots, so coils can fail again soon after replacement if the oil leak is not addressed. A persistent misfire dumps raw fuel into the catalytic converter and can damage it.

    Common Symptoms

    • Rough idle and shaking at stops
    • Flashing or steady check engine light
    • Hesitation or stumble under acceleration
    • Single-cylinder misfire code, often cyl 1 or 4
    • Repeat coil failure when valve cover gasket leaks oil onto boot

    How to Fix

    Confirm the bad coil by swapping the suspect coil to an adjacent cylinder and verifying the misfire follows it (e.g., P0301 becomes P0302). Replace the failed coil (OEM 22448-JA00C for 2007-2013, 22448-8H315-era for 2002-2006) and inspect coil boots and spark-plug wells for oil. If oil is present, replace the valve cover gasket / tube seals. Replace spark plugs at the same time; consider replacing all four coils on high-mileage cars. A new OEM coil runs roughly $30-$70 each.

    Recall 20V315000 covers certain 2013-2018 Altimas. If the primary hood latch is inadvertently released, the secondary latch may be corroded or contaminated and fail to engage, allowing the hood to open while driving. It follows earlier Altima hood-latch recalls whose remedies did not consistently eliminate the risk.

    Common Symptoms

    • VIN checked for all hood-latch campaigns
    • primary and secondary latch engagement verified
    • current dealer remedy completion confirmed

    How to Fix

    Check VIN recall status and follow Nissan's no-charge dealer remedy for the applicable campaign. For 20V315000 the remedy includes a stronger hood-release-lever spring, warning label and Owner's Manual addendum; do not assume every vehicle receives a replacement latch. Do not buy a hood latch, spring, cable, lubricant or body part from this page; VIN status and the current dealer remedy control the repair.

    Older Altimas in rust-belt climates are known for severe floorboard and underbody corrosion, especially around the front floor pan, firewall seams, and nearby structural mounting areas. Owners report soft floors, water intrusion, failed inspections, and concerns about structural integrity around suspension or subframe attachment points. The issue is most common on early-2000s cars that saw repeated winter salt exposure.

    Common Symptoms

    • soft floorboards
    • visible rust holes under car
    • water on front carpet
    • musty interior smell
    • failed safety inspection
    • subframe area corrosion

    How to Fix

    Inspection should include lifting carpets, probing floor pan seams, and checking the subframe and adjacent mounting points for perforation. Minor corrosion can sometimes be cut out and welded with rust treatment, but advanced structural rust often makes the vehicle uneconomical to repair. Keeping drains clear and addressing windshield or cowl leaks can slow recurrence after repair.

    Owner tips & cautions

    • TipPull the front carpet and inspect from inside as well as underneath; several owners found much worse rust hidden by sound deadening and wet carpet.
    • TipIf buying an early-2000s Altima in a salt state, inspect the floor pan and subframe before spending money on engine or transmission work.

    A recurring issue on 2007-2012 Altimas with a moonroof is clogged or poorly routed sunroof drains that allow water to overflow into the cabin, often soaking the front carpet and padding. Owners report musty odors, wet passenger or driver footwells, and in some cases electrical problems when water reaches connectors or body control modules under the dash or carpet area. The problem is widely discussed in owner forums and appears in complaint databases as repeated water leak/electrical symptom combinations.

    Common Symptoms

    • wet carpet
    • musty smell in cabin
    • water on front floorboards
    • electrical accessories acting erratically
    • fogging windows

    How to Fix

    Confirm the leak source with a controlled water test at the sunroof cassette and A-pillar drain outlets. Clear the drains with low-pressure air or flexible line, repair disconnected drain tubes, dry the carpet and padding completely, and inspect nearby connectors/modules for corrosion. If electrical symptoms are present, clean or replace corroded terminals and verify no water remains trapped in the insulation.

    In salt-belt states, 2002-2006 Altimas have a documented corrosion problem affecting the rear lower control arms. Severe rust can perforate the arm and eventually lead to cracking or separation, which alters rear wheel alignment and can affect vehicle control. Nissan issued a recall in affected regions after owner reports of heavy corrosion and suspension instability.

    Common Symptoms

    • rear suspension clunk
    • uneven rear tire wear
    • vehicle feels unstable from rear
    • visible rust on rear control arm
    • rear alignment out of spec

    How to Fix

    Inspect the rear lower control arms carefully, especially around spring seats and high-corrosion areas, and check whether the regional recall was completed. If rust scaling, perforation, or deformation is present, replace both rear lower control arms and perform a four-wheel alignment. Vehicles in rust-prone areas should also have the rear suspension and underbody treated with rust inhibitor after repair.

    Hydraulic power steering Altimas commonly develop leaks from the steering rack seals or high-pressure hose assemblies. Owners report groaning noises, fluid on the subframe, a burning smell from fluid contacting hot components, and progressively heavier steering effort. On higher-mileage cars the leak can become severe enough to empty the reservoir and sharply reduce steering assist.

    Common Symptoms

    • power steering fluid leak
    • groaning while turning
    • heavy steering
    • whining pump noise
    • fluid under front of car
    • burning fluid smell

    How to Fix

    Diagnosis involves checking the reservoir level, inspecting the pressure hose crimps and rack boots for fluid, and verifying whether the pump has been damaged by low fluid operation. Repairs typically involve replacing the leaking hose or steering rack, flushing the system, and refilling with the correct fluid. Alignment is usually required after rack replacement.

    RepairPal documents front struts wearing prematurely on the Altima and producing a knocking/clunking noise from the front end, especially over bumps and uneven roads. The noise often comes from worn strut internals or a failing upper strut mount/bearing. Beyond noise and a bouncy ride, worn struts increase stopping distance and reduce stability, so it is a handling-and-safety wear item commonly needed around 60,000-80,000 miles.

    Common Symptoms

    • Clunk or knock from front end over bumps
    • Bouncy or floaty ride
    • Nose dive under braking
    • Uneven/cupped front tire wear
    • Rattle from strut mount area

    How to Fix

    Inspect struts and strut mounts (also check sway-bar end links and control-arm bushings, which can mimic the same clunk). Replace front struts in matched pairs — loaded quick-strut assemblies simplify the job — and perform a four-wheel alignment afterward. OEM front strut part numbers for 2002-2006 include the 54302-xxxxx family (e.g., 54302-9E125); 2002-2007 use E4302-ZB03B-type members for some configurations.

    The CVT transmission is known for reliability issues including shuddering, jerking, and complete failure. Nissan extended the CVT warranty on some model years to 10 years/120,000 miles due to widespread problems. High-mileage CVTs are particularly at risk.

    Common Symptoms

    • Shuddering during acceleration
    • Jerky or hesitant response
    • Delayed engagement from stop
    • Whining noise from transmission
    • Complete loss of power
    • Check engine light

    How to Fix

    Change CVT fluid regularly with Nissan NS-3. Check if vehicle is covered by Nissan extended CVT warranty. If shuddering, may need valve body or complete CVT replacement. Avoid aggressive driving to prolong CVT life.

    The Altima's JATCO continuously variable transmission (RE0F10-series) uses a torque converter with a lockup (TCC) clutch, and P0741 sets when the TCM detects an rpm slip mismatch showing the lockup clutch is not engaging as commanded (stuck off). On Altima CVTs the code is commonly driven by degraded/overheated CVT fluid, a worn or sticking lockup control solenoid, or a valve body whose bores wear and leak line pressure so the TCC can't hold. On earlier RE0F10A units (notably 07-08) the valve body is prone to internal leakage, and Nissan bulletins have at times directed full CVT replacement when P0741/P0744 appears with lockup shudder. Drivers feel a shudder or judder under light acceleration (roughly 25-45 mph), rubber-band hesitation, higher-than-normal cruising rpm, and sometimes a slight surge as the converter fails to lock.

    Common Symptoms

    • Shudder or judder under light acceleration (~25-45 mph)
    • Rubber-band hesitation from a stop
    • Higher-than-normal cruising RPM
    • Slipping or surging feel
    • Check engine light

    How to Fix

    Start with a full CVT fluid inspection and replacement using genuine Nissan CVT NS-2/NS-3 fluid (burnt or contaminated fluid alone can set the code). Test/replace the lockup (TCC) solenoid. If line pressure is low or the valve body bores are worn, rebuild or replace the valve body. When internal converter/CVT damage is confirmed, the accepted repair is torque converter or full CVT assembly replacement.

    On 2013-2015 Altima sedans (L33 chassis), owners report walking up to the car, pressing the ignition button with a foot on the brake and the selector in Park, and getting nothing at all — no crank, no starter engagement — while an "I-Key Error" message appears in the combination meter. The complaint is usually intermittent at first and becomes more frequent over months. The root cause is not the Intelligent Key system despite the dash message. Nissan's shift-by-cable setup connects the console selector to a manual lever on top of the transaxle, and the transmission range switch (inhibition switch) mounted on that lever reports the actual mechanical gear position. The BCM cross-checks shift-position status before it will authorize the starter, and it sets B2603 (Shift Position Status) when it sees an invalid shift-position condition for 500 ms or more with the selector in P and the ignition ON. When the shift control cable is out of adjustment, the manual lever sits slightly off the Park detent even though the console lever feels fully in Park, so the range switch reports an ambiguous position and the BCM withholds start permission. Nissan bulletin NTB14-029b (classification EL14-013b, October 2, 2015), titled "ENGINE WILL NOT START (NO CRANK)," documents this pattern. Its confirming condition is DTC B2604 (PNP/Clutch Switch) stored past or present, and it states explicitly: "If the above condition should occur, the following DTCs may also be stored; B2603 (Shift Position Status), P0705 / P0706 (T/M Range Sensor A)." The bulletin applies to all 2013-2014 Altima sedans and to 2015 Altima sedans built before VIN breakpoints 1N4AL3AP(*)FN 878081 / May 22, 2015, 1N4AL3AP(*)FC 446505 / May 19, 2015, and 1N4BL3AP(*)FC 444362 / May 15, 2015. It covers both the QR25DE 2.5L four and the VQ35DE 3.5L V6, since the fault lives in the shift linkage and body electrical system rather than the engine. The bulletin also notes it does not apply to remote start issues.

    Common Symptoms

    • Engine will not crank when the ignition button is pressed with the selector in Park
    • "I-Key Error" message displayed in the combination meter
    • Vehicle starts normally when the selector is moved to Neutral
    • Intermittent no-start that becomes more frequent over time
    • Starter does not engage; accessories and lighting behave normally
    • Park position mechanism not fully locking the transaxle

    How to Fix

    Do not start by replacing the Intelligent Key, the key fob battery, the starter or the BCM — those are the parts most commonly thrown at this symptom and they are almost never the fault. Confirm the pattern first: scan for stored body codes and look for B2604 present or in history alongside B2603, and check whether the engine will crank with the selector in Neutral. If it starts in Neutral but not in Park, the shift control cable adjustment is the repair, and that is also the useful roadside workaround. The repair follows Nissan NTB14-029b. Clear the stored DTCs with CONSULT-III plus, move the selector from Park to Drive and back to Park, then roll the vehicle back and forth a few inches to guarantee the park position mechanism is fully engaged — the bulletin flags this step as IMPORTANT, and skipping it is the most common reason the adjustment does not hold. With the ignition OFF and the parking brake set, access the transmission range switch on top of the transmission and loosen the shift control cable nut at the manual lever, taking care not to apply force to the manual lever. Verify both the manual lever and the shift selector are in Park, then tighten the cable nut to 17.0 N·m (1.7 kg-m, 13 ft-lb) on the Altima while holding the manual lever securely in the Park position. Reinstall anything removed for access, then confirm the engine starts only when the selector is in Park or Neutral, that Park fully locks the transaxle, and that the transmission operates in Drive and Reverse. Nissan allows 0.3 hours for the Altima. If the codes return after a correct adjustment, inspect the shift control cable itself for a stretched core or a deteriorated bushing/grommet at the lever end, and check the transmission range switch connector for corrosion or backed-out pins before condemning the switch. Only after the mechanical adjustment and wiring have been verified is a range switch or BCM replacement justified.

    Multiple 2007-2012 Altima owners report the air bag warning light flashing and the passenger air bag status behaving incorrectly due to faults in the occupant classification system (OCS) or related seat sensor components. This can disable the passenger frontal air bag when it should be enabled, or trigger a persistent SRS warning light. Nissan issued service information and warranty extensions on some related OCS concerns because the issue was common enough to generate many complaints and dealer repairs.

    Common Symptoms

    • air bag light flashing
    • passenger air bag off light stays on with adult seated
    • SRS warning light illuminated
    • intermittent passenger air bag operation
    • warning returns after battery disconnect

    How to Fix

    Diagnosis requires a capable scan tool that can read SRS and OCS data, not just generic OBD-II codes. Technicians typically inspect seat harness connections, zero-point calibration, seat cushion sensor mat operation, and the occupant detection control unit. Repairs may involve OCS recalibration, harness repair, or replacement of the passenger seat cushion/sensor assembly followed by SRS initialization.

    Altimas equipped with Nissan's standard Forward Emergency Braking / Automatic Emergency Braking (part of the Safety Shield 360 / Forward Collision suite) are widely reported to activate suddenly when no collision is imminent — so-called 'phantom braking.' Owners and NHTSA complaints describe the brakes locking up or slamming on while crossing railroad tracks, on bridges, approaching parking-garage ramps, at intersections, and at highway speed (e.g., a 2019 Altima owner reporting random activation), creating rear-end and loss-of-control collision risk. The defect is the subject of multiple class-action lawsuits naming the Altima (model years 2015 and newer) alleging the AEB/FEB system was 'not road ready.' NHTSA's related Nissan AEB probe found hundreds of complaints and several crashes.

    Common Symptoms

    • Sudden hard braking with no obstacle present
    • Brakes lock up on railroad tracks, bridges, or ramps
    • Unexpected deceleration at highway speed
    • Forward emergency braking / collision warning false alerts

    How to Fix

    Dealers may apply ADAS/forward-camera software updates or recalibrate the front radar/camera; persistent cases may require sensor or module replacement. Keeping the windshield, front camera, and grille radar area clean and free of obstructions can reduce false triggers. The system can be temporarily disabled via the vehicle settings, but it re-enables on each restart. Owners experiencing repeated phantom braking should file an NHTSA complaint and document incidents.

    A well-documented problem on 2002-2006 Altima involves failure of the engine control module (ECM) relay, which can interrupt power to the ECM while driving or prevent the car from starting. Owners report sudden stalling, intermittent crank-no-start, or an engine that dies and restarts after cooling down. Nissan issued a safety recall because relay heat damage and internal failure could cause an unexpected engine stall.

    Common Symptoms

    • engine stalls while driving
    • intermittent no-start
    • cranks but will not start
    • engine restarts after sitting
    • loss of power with warning lights illuminated

    How to Fix

    Confirm recall completion status by VIN first. Diagnosis typically includes checking for ECM power loss, relay operation, and signs of heat damage or intermittent contact in the IPDM/relay circuit. The fix is replacement of the ECM relay with the updated part per recall procedure; if symptoms persist, inspect related fuse box terminals and wiring for overheating or poor pin tension.

    The power window regulator (the cable-and-rail mechanism that raises the glass) is a frequently reported failure on these Altimas. The plastic cable guides or the cable itself break, so the window jams, drops into the door, or rises crooked/off-track. Owners and dealers describe it as very common, and Nissan ran a service campaign (not a full recall) to replace regulators on affected cars. The front driver's door is most often affected because it is used most.

    Common Symptoms

    • Window won't go up or down
    • Grinding/clunking from inside the door
    • Glass drops into the door or sits crooked
    • Window moves then jams off-track

    How to Fix

    Distinguish a regulator failure (grinding, cable snap, glass off-track or fallen) from a bad motor or window switch. Replace the regulator — front sedan units are OEM 80721-JA000 (driver/left) and 80720-JA000 (passenger/right); the 2008-2013 coupe uses 80721-JB100; some sedans cross to 80771-JA000. Regulators are sold with or without the motor. After install, run the auto-up reset/initialization. Typical repair is $150-$400 per window.

    On the Altima's 2.5L QR25DE four-cylinder (and Bank 1 of the 3.5L V6), P0171 sets when the fuel-trim correction runs beyond about +25% because unmetered air is entering the engine downstream of the mass-air-flow (MAF) sensor. The two dominant Altima-specific culprits are (1) the flexible rubber intake air duct/boot between the MAF and throttle body, which grows brittle and splits at the accordion folds with age and underhood heat, and (2) hardened, shrunken intake manifold gaskets that let in a vacuum leak. A dirty or contaminated MAF sensor element that under-reports airflow is the third common trigger and is the cheapest to rule out. On the inline-4 there is only one bank, so P0171 appears alone; on the V6 it typically shows up paired with P0174 when the leak or MAF fault affects both banks.

    Common Symptoms

    • Check engine light
    • Rough or unstable idle
    • Hesitation or stumble on acceleration
    • Reduced fuel economy
    • Occasional hard start when cold

    How to Fix

    Smoke-test the intake tract for leaks. Replace a cracked intake air duct/boot; replace the intake manifold or plenum gasket if leaking. If no leak is found, clean the MAF sensor with MAF-specific cleaner and replace it if trims don't recover. Clear codes and confirm long-term fuel trim returns to roughly +/-10% after the repair.

    P0174 references Bank 2, which physically exists only on the Altima's 3.5L VQ35DE V6 (the inline-4 has no Bank 2), so this code points specifically at the V6 rear cylinder bank. It nearly always appears together with P0171, and that pairing is the diagnostic tell: a lean condition on BOTH banks is caused by something common to the whole engine rather than one injector. On the VQ35DE the usual causes are shrunken/hardened intake manifold and plenum gaskets that develop vacuum leaks, a cracked PCV or intake hose, or a dirty MAF sensor under-reporting airflow to both banks. Nissan issued ECM-reprogram guidance (TSB NTB19-030) for lean-code complaints on 2016-2018 V6 Altima/Maxima where fuel trims are borderline, so a software update can be part of the fix after mechanical leaks are ruled out.

    Common Symptoms

    • Check engine light (usually P0171 + P0174 together)
    • Rough idle
    • Hesitation and reduced power
    • Poor fuel economy
    • Intermittent stalling at idle

    How to Fix

    Confirm the P0171/P0174 pair, then smoke-test the V6 intake. Replace the intake manifold/plenum gaskets and any cracked PCV or intake hoses to seal the vacuum leak. Clean or replace the MAF if trims stay lean. Apply the applicable ECM reprogram (per Nissan bulletin) if hardware is sound but trims remain out of spec. Verify long-term fuel trim on both banks returns to roughly +/-10%.

    Certain 2005-2006 Altimas were subject to a brake master cylinder recall because internal seal damage could allow brake fluid bypass inside the cylinder. Owners describe a soft or sinking brake pedal, increased stopping distance, and inconsistent braking feel. In severe cases, braking performance is reduced enough to create a crash risk.

    Common Symptoms

    • soft brake pedal
    • brake pedal slowly sinks to floor
    • longer stopping distances
    • inconsistent brake feel
    • need to pump brakes

    How to Fix

    Verify recall completion status and inspect for pedal sink with steady pressure. If the master cylinder is original or symptoms are present, replace the master cylinder, bleed the hydraulic system thoroughly, and inspect pads/rotors for contamination or secondary wear from prolonged low-pressure operation. A scan tool ABS bleed may be needed if air entered the ABS hydraulic unit.

    A failed front ABS wheel speed sensor (or its corroded/damaged wiring) is a common cause of the simultaneous ABS, VDC (vehicle dynamic control), and SLIP warning lights on the Altima. Because the sensor feeds speed data to multiple modules, one bad sensor lights several warnings and disables ABS and traction/stability control. The sensors live at the wheels and fail from road debris, corrosion, and electrical wear. Driving is possible but anti-lock braking and stability assist are inactive until repaired.

    Common Symptoms

    • ABS, VDC/traction, and SLIP lights on together
    • Speedometer dropout in some cases
    • ABS not engaging in hard stops
    • Stability/traction control disabled

    How to Fix

    Read ABS codes with an ABS-capable scanner to pinpoint the exact wheel before buying parts (a dirty tip or chafed wire can sometimes be cleaned/repaired instead of replaced). Replace the failed front sensor — OEM front left/right is 47910-JA000 (2007-2013 Altima / 2009-2014 Maxima); later body uses 47910-3TA1A/3TA2A. It is roughly a one-hour-per-wheel DIY job.

    NHTSA recall 23V882000 and Nissan campaign PC997 cover five specific 2024 Altima vehicles. One or more bolts connecting the electronic power-steering unit to the steering rack may have been under-torqued; steering vibration can loosen the connection, potentially lock the steering gear and cause loss of control. Noise or vibration may precede the condition.

    Common Symptoms

    • VIN checked for 23V882000/PC997
    • new steering noise or vibration documented
    • dealer recall remedy confirmed

    How to Fix

    Check the VIN for open recall 23V882000/PC997. The authorized remedy is dealer replacement of the complete steering-gear assembly at no charge; do not substitute bolt tightening or an unverified retail gear. Do not buy a steering rack, EPS unit, bolts, alignment service or diagnostic tool from this page; VIN eligibility and the recall remedy control the repair.

    P0420 (catalyst system efficiency below threshold) is one of the most common check-engine codes on the 2.5L Altima. The integrated exhaust-manifold/catalyst on these cars loses efficiency as the substrate degrades, the downstream oxygen sensor begins tracking the upstream sensor, and the ECM sets P0420. Untreated upstream causes — misfires, oil consumption, or a failing O2 sensor — accelerate catalyst breakdown. Because the front (main) catalyst is integrated with the exhaust manifold on many model years, replacement is costlier than a typical under-car converter. Nissan ran emissions recall PC717 on certain 2018 Altimas (QR25DE) that replaced the exhaust manifold/three-way catalyst assembly and two exhaust sensors at no charge.

    Common Symptoms

    • Check engine light with P0420
    • Reduced fuel economy
    • Sometimes rotten-egg smell or sluggish performance
    • Failed emissions test

    How to Fix

    Diagnose the root cause before replacing the converter: check for misfires, oil consumption, exhaust leaks, and a lazy/failed downstream O2 sensor (a bad rear sensor alone can mimic P0420). Replace the catalyst/manifold assembly with a CARB-compliant unit where required. For affected 2018 models verify VIN against emissions recall PC717 for a free repair. Average converter replacement is roughly $1,200-$1,850 depending on whether the integrated manifold assembly is needed.

    On the second-generation Altima the vacuum cut valve bypass solenoid lives just inside the rear wheel well, beside the fuel tank and the spare tire well, bolted to a small steel bracket under the body. It is one of the most rust-exposed electrical components on the car, and in the salt belt the bracket assembly typically corrodes badly — owners in the Northeast describe having to soak the fasteners for a day before the bolts will come out without snapping. The solenoid is normally closed and opens only when the ECM grounds it to admit intake manifold vacuum to the fuel tank for the on-board EVAP leak diagnostic. P1490 is the circuit-side complaint: the ECM drove the valve and the electrical feedback was wrong, which on this car is nearly always either a dead solenoid coil or a corroded connector, not a leak. The companion code P1491 is set when the valve is electrically fine but the tank does not respond to the test, so which of the two codes you have narrows the search considerably before you touch anything. Drivers notice essentially nothing beyond the check engine light — no stumble, no hard start, no smell of fuel — and the car will drive indefinitely with the code present. The consequence is an emissions failure and a MIL that hides any more serious code that might follow, and because the EVAP monitor only runs under specific fuel-level and temperature conditions, clearing the code buys a few days of a dark dash before it returns.

    Common Symptoms

    • Check engine light on, car drives normally
    • Solenoid does not click when 12V is applied at the terminals
    • Heavily rusted bracket and hardware at the rear of the car
    • Emissions inspection failure
    • Code reappears within days of being cleared

    How to Fix

    The diagnostic that settles this takes ten minutes. Jack the rear of the car, find the solenoid just inside the wheel well next to the tank, and unplug it. Apply battery voltage directly across the two terminals: a good valve clicks audibly and you can feel or hear the air passage open, and it should close again the instant power is removed. If there is no click, the solenoid is dead and needs replacing. If it clicks properly, put the meter on the harness instead — check for continuity from the solenoid connector back to the ECM, check the ground, and inspect the connector for the green corrosion and water intrusion that is endemic at this location. Cleaning the pins and sealing the connector with dielectric grease resolves a meaningful share of these without any parts at all. When the valve itself is bad, the part is the Nissan 14933-54U0A cut valve solenoid shared across Altima, Maxima and Pathfinder of this era; owners have sourced good used units for well under $50, and aftermarket replacements are widely available, while the genuine Nissan part runs considerably more. Before you start, soak the bracket bolts with penetrating oil the day before — rusted-in hardware, not the valve, is what turns this into a long job. Replace the short rubber hoses at the valve while you are there, since they crack at this age. Clear the code afterward and drive the car through a proper cold-start-plus-cruise cycle with a partly filled tank so the EVAP monitor can run and set to ready.

    After a loose/failed gas cap, the most common cause of EVAP leak codes (P0455 large leak, P0456 very small leak) on the Altima is a failed EVAP canister vent control valve mounted near the charcoal canister at the rear of the vehicle. The valve seal sticks or fails to seal, so the EVAP system can't pass its self-test. It typically starts as an intermittent small leak (P0456) and worsens into a gross leak (P0455). It does not affect drivability but causes a persistent check engine light and an emissions-test failure. Nissan issued TSBs (NTB09-020F, NTB13-097J, NTB17-082a) addressing the diagnostic path and this component.

    Common Symptoms

    • Check engine light with no drivability change
    • Failed state emissions / smog test
    • Fuel odor in some cases
    • Code returns after replacing only the gas cap

    How to Fix

    Begin with a known-good OEM gas cap (aftermarket caps often will not seal). If the code persists, smoke-test the EVAP system; a sticking/leaking vent valve is the usual culprit and is replaced as a unit. OEM vent control valve part numbers for this generation include 14935-JF00E / 14935-JF01C / 14935-JF02C (supersession family 14935-JF00A through JF02C). Valve runs roughly $60-$110; OEM gas cap $25-$40.

    A recurring higher-mileage Altima problem is front wheel bearing wear, often first noticed as a humming or growling noise that increases with road speed. As the bearing deteriorates, owners may feel vibration, looseness, or see ABS warnings if the integrated wheel speed signal becomes erratic. This is widely reported in repair databases and owner forums, especially on cars driven on rough roads.

    Common Symptoms

    • humming noise from front wheel
    • growling that changes with speed
    • vibration
    • ABS light
    • wheel play
    • noise changes when turning

    How to Fix

    Diagnosis includes road testing for load-sensitive humming, checking for play at the wheel, and using a chassis ear or scan tool to compare wheel speed signals if ABS lights are present. Repair typically requires replacing the affected hub/bearing assembly or pressing in a new bearing depending on model year and setup. An alignment check is wise if other front-end wear is present.

    Dashboards on these Altimas (most heavily reported on 2007-2009 cars in hot, sunny climates) degrade with heat and UV exposure, becoming shiny, sticky/gooey, and reflective, and can crack along the seams. The high-gloss reflection off the windshield creates a glare that owners report impairs forward visibility — a genuine safety concern. The material can come off in chunks when touched. Nissan never issued a federal recall, but a Florida class-action lawsuit over the 2008-2009 melting dashboards reached a court-approved settlement (final approval Jan 2017, valued $5.3M-$59.3M) under which Nissan covers all but $250 of the $1,500-$2,000 replacement cost for eligible Florida owners.

    Common Symptoms

    • Shiny, sticky, or gooey dashboard surface
    • Bright glare/reflection on the windshield in sun
    • Cracking along dash seams
    • Dash material peeling or coming off in pieces

    How to Fix

    Replace the dashboard pad/assembly with a current-design part, or fit an aftermarket dash cover/cap to eliminate glare as a lower-cost option. Eligible 2008-2009 Florida owners should file under the class settlement to have all but $250 of the replacement covered. NHTSA complaints help document the safety/glare aspect. Out-of-pocket replacement typically runs $1,500-$2,000.

    The exhaust manifold on the Altima is prone to developing cracks from repeated heat cycling, producing a ticking/tapping noise from the front of the engine that is loudest on cold start (and often quiets as the metal expands and the crack closes), along with an exhaust smell and a leak ahead of the catalyst. On many 2.5L model years the manifold is integrated with the front catalytic converter, so a cracked manifold and a P0420 catalyst fault often go together and make replacement more involved.

    Common Symptoms

    • Ticking/tapping from the engine bay, worst on cold start
    • Exhaust or sulfur smell
    • Hissing/puffing exhaust leak sound
    • Often paired with a P0420 catalyst code

    How to Fix

    Confirm the leak by listening for a cold-start tick and inspecting the manifold/gasket for soot or visible cracks (a smoke or soapy-water test on the flange helps). Replace the cracked exhaust manifold (or the integrated manifold/catalyst assembly on cars where they are one piece) and renew the manifold and downpipe gaskets. Address related catalyst codes at the same time. On affected 2018 cars the manifold/catalyst was covered under emissions recall PC717.

    On the Altima, P0128 sets when the ECM sees that engine coolant fails to reach its target operating temperature (roughly 180-200F) within the expected time/warm-up cycle. The overwhelming Altima-specific cause is a thermostat stuck open (or a thermostat that opens too early), which lets coolant circulate continuously and never lets the engine fully warm. On the 2.5L QR25DE there are effectively two temperature-control components — the main thermostat behind the cylinder head and a secondary water-control valve at the front of the engine — and best practice is to replace both together, because replacing only one frequently leaves the code active. Drivers most often notice weak cabin heat in cold weather and a temperature gauge that sits low or drops on the highway. Left unfixed it causes poor fuel economy, higher emissions, and can fail an emissions/smog test.

    Common Symptoms

    • Check engine light
    • Weak or no cabin heat in cold weather
    • Temperature gauge reads low or drops at highway speed
    • Reduced fuel economy
    • Emissions/smog test failure

    How to Fix

    Verify actual coolant temperature with a scan tool to confirm the thermostat is opening early/stuck open rather than a faulty coolant temp sensor. Replace the thermostat; on the 2.5L QR25DE also replace the secondary water-control valve at the same time. Refill and bleed the cooling system, then confirm the engine reaches full operating temperature and the code stays cleared.

    Owners report widespread clearcoat/paint peeling and flaking, with the hood and roof typically the worst-affected horizontal panels, sometimes coming off in large jagged strips. A class-action lawsuit (filed Nov 2023) alleges a defective/insufficient primer on 2017-present Nissan vehicles, claiming some colors received less primer and paint, so the finish peels in roughly half the 10-15 years a factory paint job should last. Numerous earlier 2013-2016 complaints exist on CarComplaints. Nissan recalled/addressed paint on some Rogue and Infiniti models but not the Altima, which has frustrated owners.

    Common Symptoms

    • Clearcoat peeling/flaking on hood and roof
    • Paint coming off in strips, sometimes after washing/waxing
    • Dull, chalky, or primer-exposed patches
    • Chipping on bumpers and edges

    How to Fix

    There is no Altima recall, so repair is typically a body-shop respray of the affected panels (and ideally the full roof/hood) down to good primer; cost depends on panel count. Owners may pursue goodwill assistance through Nissan or join the pending paint class action. Document early with photos. Panel repaint commonly runs a few hundred dollars per panel up to several thousand for multiple panels.

    Typical repair cost:$300 - $3,000

    The plastic gears in the HVAC air-mix (blend) and mode door actuators strip, producing a repetitive clicking or knocking sound from behind the dash, usually loudest when the climate system is turned on or the temperature is changed. A failed blend actuator leaves the temperature stuck (often only hot or only cold), and a failed mode actuator leaves airflow stuck on one outlet (e.g., defrost only, won't switch to face/feet). These actuators cannot be repaired and must be replaced.

    Common Symptoms

    • Repetitive clicking/knocking from dash when A/C or temp is adjusted
    • Temperature stuck on hot or cold
    • Air stuck blowing from one set of vents
    • Noise stops when ignition is off

    How to Fix

    Identify which actuator is clicking (air-mix vs. mode) and replace the failed unit. The air-mix/blend door actuator is OEM 27732-AL610 (fits 2007-2012 Altima 2.5L and 3.5L; later body uses 27732-4GA0C). Access is via the passenger side behind the glovebox; full dash removal is generally unnecessary. After replacement, recalibrate the climate system per the reset procedure. Part is inexpensive (~$30-$80); labor varies by location.
