1998-2025 Nissan Altima Problems: 39 Known Issues

How to Fix

Have a technician diagnose any start-up rattle or timing-related warning promptly; the repair owners report is replacing the timing chain, guides and tensioner. Summarized from the owner reports linked here; not a manufacturer finding. Your vehicle's equipment and history may differ; a technician must confirm the cause. The historical issue ID contains P0016, but the reviewed reports do not establish that code for this card; no P0016 tag or invented timing offset is shown.

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 engine oil is replaced (the 1.5L Rogue engines additionally get an ECM reprogram). 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.

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.

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.

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+.

How to Fix

Have a technician confirm which cylinder is affected and why before replacing coils. Summarized from the owner reports linked here; not a manufacturer finding. Your vehicle's equipment and history may differ; a technician must confirm the cause. The coil and spark plug image illustrates one reported repair outcome. It does not justify replacing every coil or prove that a coil caused a later converter problem.

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.

How to Fix

Have a Nissan dealer check the VIN for recall 10V193. Nissan sends technicians from the production plant to the dealer to inspect the front side member and, if necessary, repair the welds at no cost to you. This is inspection followed by weld repair only if needed; it does not call for automatic replacement of the rail or vehicle structure.

How to Fix

Check the VIN for 26V023000/PD185 and arrange the no-charge dealer replacement of the affected door strikers. Until remedied, verify every door is fully latched before moving the vehicle and follow Nissan's owner instructions.

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.

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.

How to Fix

Have the sunroof drains tested and cleared and the carpet dried; owners report the rear drain lines need the headliner removed to reach. Summarized from the owner reports linked here; not a manufacturer finding. Your vehicle's equipment and history may differ; a technician must confirm the cause. The cleared-drain image is a comparison, not proof that a leak has been repaired. Test drainage and dry the carpet; no body-control-module failure is established by these reports.

How to Fix

Have a Nissan dealer check the VIN for recall 09V358. Dealers replace both left and right front strut insulators free of charge. Nissan's owner letter says that if you hear a loud noise from the front suspension, take the car to a Nissan dealer for immediate repair.

How to Fix

Have a Nissan dealer check the VIN for PC516 and follow NTB17-018. For an eligible vehicle, replace the electronic steering-lock unit with the campaign service unit and its two tamper-resistant mounting bolts, then complete the specified checks. The new unit has no column-lock function, so the steering column no longer locks when ignition is off. This is the manufacturer campaign repair, not a DIY bypass. Diagnose other causes if the vehicle is ineligible or the no-start remains.

How to Fix

Have a technician inspect the front struts and mounts and replace worn parts. Ask a Nissan dealer to check the VIN for recall 09V358 (upper front strut insulators). Summarized from the owner reports linked here; not a manufacturer finding. Your vehicle's equipment and history may differ; a technician must confirm the cause. A torn dust boot in the representative image does not by itself prove the damper has failed. Confirm which parts are worn; the separate insulator recall has its own VIN eligibility and repair.

How to Fix

Have a technician check the front hub bearings for play and noise and replace a worn hub bearing. Summarized from the owner reports linked here; not a manufacturer finding. Your vehicle's equipment and history may differ; a technician must confirm the cause.

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.

Owner tips & cautions

• TipChange CVT fluid regularly with Nissan NS-3.
• WarningThis is a high-severity issue - ignoring it can lead to costly repairs or safety concerns. Address it promptly.
• TipGet a proper diagnosis before replacing parts - similar symptoms can have different causes

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.

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.

How to Fix

Have a dealer or qualified technician read the air bag system codes and repair the occupant classification system; this is a safety system, so do not attempt a DIY reset. For a 2007-2008 car, ask a Nissan dealer to check the VIN for recall 08V521: the dealer tests the occupant classification signal with a special tool and, if necessary, replaces the passenger seat cushion containing the sensor hardware. Summarized from the owner reports linked here; not a manufacturer finding. Your vehicle's equipment and history may differ; a technician must confirm the cause. The separate 08V521 recall does not extend to a 2010 vehicle just because it has a similar warning. Do not use a reset or an illustration to decide that the passenger airbag is working.

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.

How to Fix

Check if your VIN is covered by recall 19V316000 or 18V922000. Nissan dealers will inspect the fuel pump lock ring and tighten it (or replace the fuel pump if the ring is detached), or lock the fuel tube retainer clip, free of charge.

Owner tips & cautions

• WarningThis is a high-severity issue - ignoring it can lead to costly repairs or safety concerns. Address it promptly.
• TipGet a proper diagnosis before replacing parts - similar symptoms can have different causes
• TipSearch Nissan Altima forums and owner groups for real-world experiences and DIY guides
• TipGet multiple quotes from independent mechanics - dealer prices can be 2-3x higher for the same repair

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%.

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; retightening the bolts is not the recall remedy.

How to Fix

Have a qualified technician locate the power-steering leak and repair the confirmed rack or pressure-hose fault, then refill and verify the system. Under Nissan NTB12-030, a replacement high-pressure hose for the listed 2007-2011 vehicles comes without its pressure sensor: reuse the existing sensor unless it has its own fault, always fit a new sensor O-ring and replace both copper washers at the pump connection. Do not replace unrelated hoses as a set; a sensor-only fault does not require a new hose. Follow the VIN-specific service procedure and parts catalog. These are owner-reported leaks, not a universal defect or a promise of free repair. If assist is lost, stop safely and arrange assistance.

How to Fix

Replace A/C compressor assembly. If internal failure, flush system, replace condenser, receiver/drier, and expansion valve. Use quality replacement parts. Some owners opt for aftermarket compressors to save cost.

Owner tips & cautions

• TipConsider OEM parts for critical components like sensors and electrical parts - aftermarket can be unreliable
• TipGet a proper diagnosis before replacing parts - similar symptoms can have different causes

How to Fix

Diagnosis includes scanning for correlation and sensor circuit codes, checking live RPM signal during cranking, and inspecting harness connectors for oil contamination or heat damage. The most reliable fix is replacing the failed sensor(s) with OEM-quality parts and clearing codes; in some cases both cam and crank sensors are replaced together due to similar age and failure patterns.

Owner tips & cautions

• TipUse OEM or OEM-supplier sensors; many owners report repeat failures within months when using the cheapest aftermarket cam/crank sensors.
• TipIf one sensor fails on a high-mileage car, many owners proactively replace the matching cam/crank sensors together to avoid another breakdown soon after.

How to Fix

Have dealer perform parasitic draw test. Common causes include Intelligent Key system, radio, or BCM. Update software to latest version. Use battery maintainer if vehicle sits for extended periods.

Owner tips & cautions

• TipGet a proper diagnosis before replacing parts - similar symptoms can have different causes
• TipSearch Nissan Altima forums and owner groups for real-world experiences and DIY guides
• TipGet multiple quotes from independent mechanics - dealer prices can be 2-3x higher for the same repair

How to Fix

Update infotainment software. Perform system reset by holding power button. Delete paired devices and re-pair. If persistent, head unit may need replacement. Check for Nissan service bulletins.

Owner tips & cautions

• TipGet a proper diagnosis before replacing parts - similar symptoms can have different causes
• TipSearch Nissan Altima forums and owner groups for real-world experiences and DIY guides
• TipGet multiple quotes from independent mechanics - dealer prices can be 2-3x higher for the same repair

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.

How to Fix

Have a technician confirm the cause before replacing the converter. For a 2007-2010 SULEV car, ask a Nissan dealer to check the VIN for emissions recall campaign PC131 (2007-2008, bulletin NTB13-056a), PC130 (2009, bulletin NTB12-092) or PC129 (2010, bulletin NTB12-040c): Nissan reprograms the engine control module and, depending on mileage and a leak check, replaces the exhaust manifold catalyst and front exhaust tube at no charge. Summarized from the owner reports linked here; not a manufacturer finding. Your vehicle's equipment and history may differ; a technician must confirm the cause. The illustrated new manifold catalyst and front tube are conditional replacement parts. The campaign also requires ECM programming; buying a converter does not complete it.

How to Fix

Per Nissan bulletin NTB17-082E, the technician first rules out a loose fuel fill cap, confirms the leak at the vent control valve-to-canister joint, then replaces the vent control valve as an assembly (the O-ring is no longer sold separately). Nissan's NTB09-020f notes that on 2007-2011 vehicles a loose fuel cap can itself cause P0442, P0455 or P0456. Normal warranty rules apply; this is not a recall or a promise of free repair.

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.

How to Fix

Have the dashboard inspected; the remedy owners describe is replacing the dash. A Florida class settlement covered only Florida 2008-2009 Altimas and expired on April 29, 2017. Summarized from the owner reports linked here; not a manufacturer finding. Your vehicle's equipment and history may differ; a technician must confirm the cause. The expired settlement is historical context, not a current reimbursement offer. Do not fit a cover that obstructs airbag deployment or visibility.

How to Fix

Per Nissan bulletin NTB10-102a, the technician records the active codes, clears them and road-tests above 13 mph to confirm the code returns, then checks the suspect sensor for damage, its output with a wheel sensor tester, the harness for shorts and the connectors for bent pins or corrosion before replacing anything. Nissan says not to replace a sensor based on the code alone. Normal warranty rules apply; this is not a recall or a promise of free repair. A stored code alone does not establish a failed sensor. The sensor, harness or connector repair follows the diagnostic result; do not infer that driving with a brake warning is safe.

How to Fix

Have a technician inspect the exhaust manifold and catalyst assembly for cracks and leaks. Nissan bulletin NTB12-120a tells technicians replacing the exhaust manifold and three-way catalyst on 2007-2010 QR25DE cars (non-SULEV) built before May 24, 2010 to discard the exhaust manifold stay; on cars built before November 10, 2007 the heat shields may also need replacing. For a 2007-2010 SULEV car, ask a Nissan dealer to check the VIN for emissions recall campaign PC131 (2007-2008), PC130 (2009) or PC129 (2010), under which any cracked manifold catalyst or front exhaust tube with catalyst is replaced regardless of mileage. Summarized from the owner reports linked here; not a manufacturer finding. Your vehicle's equipment and history may differ; a technician must confirm the cause. Exhaust fumes in the cabin need prompt inspection. Do not use the drawing to decide whether a leak is safe or whether a particular emissions configuration qualifies.

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.

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.

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); the 2013+ body uses a different air-mix actuator by trim (e.g., 27742-1LA0A or 27732-3JC1A), so confirm by VIN. 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. The OEM part runs roughly $110-$170 (aftermarket units cost less); labor varies by location.
