    On the 2016-2021 Chevrolet Malibu, gM recalled 2016-2021 Chevrolet Malibu (and 2019-2021 Cadillac XT4) vehicles because the rear seat belt retractors may have been assembled with loose or missing fasteners. A retractor that is not properly bolted to the body structure cannot lock and restrain the occupant as designed in a crash, so a rear-seat passenger — often a child in a booster — may not be held. The defect is invisible in normal use: the belt extends and retracts normally, so no owner symptom exists other than, on some cars, a rattle or a retractor that moves when pulled on. This affects the ninth-generation body across the whole engine range.

    Common Symptoms

    • Rear seat belt retractor loose or moving in its mounting
    • Rattle from the rear side trim
    • No visible symptom in most affected vehicles

    How to Fix

    Free recall remedy under NHTSA campaign 21V649 (GM number N212333380): dealers inspect the rear seat belt retractors and tighten or install the fasteners as necessary at no charge. Owner notification letters went out beginning October 4, 2021. Verify remedy status by VIN on nhtsa.gov/recalls — this is a fast inspection but it is genuinely load-bearing on a car regularly carrying rear passengers.

    On the 2013-2024 Chevrolet Malibu, the 2013+ Malibu uses an electric power steering (EPS) system with a column-mounted motor that is prone to failure. The motor develops internal faults causing intermittent or complete loss of power steering assist, making the car extremely difficult to steer at low speeds. GM issued TSB 18-NA-205 and NHTSA investigated numerous complaints. The steering column module and torque sensor can also fail, triggering a "Service Power Steering" message on the DIC.

    This issue also affects: Cadillac XT6, Chevrolet HHR, Chevrolet Silverado 1500

    Common Symptoms

    • "Service Power Steering" message on DIC
    • Steering suddenly becomes very heavy
    • Intermittent loss and return of power assist
    • Steering wheel jerks or pulls to one side
    • Warning light clears after restart but returns

    How to Fix

    Have the EPS motor and torque sensor diagnosed with a scan tool — the module stores specific fault codes. Replacement of the EPS motor assembly costs $400-$800 for parts and $200-$400 for labor. In some cases, a software recalibration of the EPS module resolves intermittent faults. Check for applicable GM TSBs, as some vehicles may qualify for extended warranty coverage. Never ignore a power steering warning — sudden loss of assist at highway speed is a safety hazard.

    On the 2008-2019 Chevrolet Malibu, the single most common P0420 pattern on the Malibu is on the 2008-2012 2.4L Ecotec (LE5/LE9), whose low-tension piston rings are notorious for excessive oil consumption. Burned oil sends phosphorus and other contaminants into the exhaust, which glazes and poisons the catalytic converter. The downstream O2 sensor eventually mirrors the upstream sensor, telling the ECM the converter is no longer storing oxygen, and P0420 sets. The 2.5L (2013-2015) and 2.0L/1.5L turbos see it too, usually from a failed PCV in the valve cover or an aging original converter. Replacing the cat without fixing oil consumption first will kill the new one.

    This issue also affects: Chevrolet Cruze, Chevrolet Equinox, Chevrolet Silverado 2500HD

    Common Symptoms

    • Check engine light
    • Reduced fuel economy
    • Sulfur/rotten-egg exhaust smell
    • Low engine power
    • Oil level dropping between changes

    How to Fix

    Confirm no exhaust leaks, misfires, or slow O2 sensors first. Check oil consumption — if the engine burns oil, repair that (PCV valve-cover replacement on turbos, or piston-ring/short-block repair on the 2.4L) before touching the converter. Once the source is corrected, replace the Bank 1 catalytic converter (or the failed downstream O2 sensor if that is the actual fault) and clear the code.

    On the 2012-2023 Chevrolet Malibu, p0455 indicates a large EVAP leak (a hole ~0.040 inch or bigger). On the Malibu the leading cause — more than half of cases across GM cars of this era — is a loose, missing, or failed fuel cap (or, on 2016+ capless cars, a bad filler-neck seal). The second most common cause is a failed EVAP purge valve stuck open, a notoriously common GM failure shared across the Impala, Camaro, and others. Cracked or disconnected canister/vent hoses can also let enough vapor escape to trip the gross-leak monitor.

    This issue also affects: Chevrolet Corvette, Buick Encore GX, Chevrolet Traverse

    Common Symptoms

    • Check engine light
    • Noticeable fuel vapor smell
    • Fuel cap warning message in some models
    • Failed emissions test
    • No performance change

    How to Fix

    Confirm the gas cap is present, tight, and its seal is intact (or inspect the capless filler seal on 2016+). If the cap is fine, replace the EVAP purge valve. If the code persists, smoke-test the system to find the large leak — commonly a cracked canister hose or a failed vent valve — and repair it.

    On the 2012-2023 Chevrolet Malibu, p0442 flags a small EVAP leak (roughly a 0.020-0.040 inch hole). On 2012-2016 Malibus with a conventional threaded gas cap, the most common cause is a cracked or flattened cap O-ring. On the 2016+ ninth-gen cars with the capless fuel filler, the culprit is usually the filler-neck seal or debris holding the spring-loaded flap slightly open. On all years, a leaking or weak EVAP purge valve — a well-known failure across GM platforms of this era — is the next most likely source. Cracked charcoal-canister hoses round out the list.

    This issue also affects: Chevrolet Traverse, Chevrolet Equinox, Chevrolet Silverado 1500

    Common Symptoms

    • Check engine light
    • Faint fuel vapor smell
    • No drivability change
    • Failed emissions/readiness test

    How to Fix

    Start with the cheapest checks: inspect/replace the gas cap and O-ring (or clear debris and inspect the capless filler seal on 2016+). If that does not resolve it, replace the EVAP purge valve. When the simple items check out, run a professional smoke test to pinpoint the leak (canister, hoses, or vent valve) and repair the leaking component.

    On the 2016-2024 Chevrolet Malibu, the 1.5L turbocharged engine in 2016+ Malibu has a PCV system integrated into the valve cover that commonly fails, causing excessive oil consumption, rough idle, and check engine lights. The PCV diaphragm ruptures, creating a vacuum leak and allowing oil to be ingested into the intake. This is the same engine family as the Equinox 1.5T. GM has released an updated valve cover design.

    This issue also affects: Buick Cascada, Buick Encore GX, Buick Encore

    Common Symptoms

    • Excessive oil consumption (1qt per 2,000 miles)
    • Check engine light with lean or misfire codes
    • Rough idle, especially when cold
    • Oil in intake manifold or intercooler
    • Whistling noise from engine (vacuum leak)

    How to Fix

    Replace valve cover assembly which includes the integrated PCV system. GM updated design is less prone to failure. Check for oil contamination in the intercooler and intake - clean if found.

    On the 2016-2023 Chevrolet Malibu, p0303 (cylinder 3 misfire) shows up frequently on the 2016-2018 Malibu 1.5L turbo (LFV) and is discussed heavily on the Malibu forums. The direct-injected 1.5T is prone to carbon buildup on the intake valves, which disrupts airflow and causes lean/rough combustion and misfires; a GM service bulletin describes misfire conditions from significant carbon buildup due to incomplete fuel burn. On top of that, a weak coil or worn spark plug at cylinder 3 is the classic ignition-side cause. Fuel injector #3 problems and PCV/vacuum leaks can contribute. Because the difference between a plug and a valve-carbon repair is large, proper diagnosis matters.

    This issue also affects: Buick Lucerne, Cadillac CT5, Cadillac DeVille

    Common Symptoms

    • Check engine light (may flash)
    • Rough idle and shaking
    • Hesitation and loss of power on acceleration
    • Poor fuel economy
    • Occasional stalling under load

    How to Fix

    Inspect and, if worn/fouled, replace the cylinder 3 spark plug; swap the #3 coil with an adjacent one to see if the misfire follows it and replace the coil if so. If ignition parts are good and misfire persists, check for carbon buildup on the intake valves (per GM bulletin) and perform a walnut-blast/intake-valve cleaning; verify injector #3 and check for vacuum/PCV leaks. Stop driving if the CEL flashes to protect the catalytic converter.

    On the 2013-2020 Chevrolet Malibu 2.5L Ecotec, the 2.5L Ecotec 4-cylinder engine in the 2013-2020 Malibu consumes oil at a rate well beyond what GM considers normal, with some owners reporting 1 quart every 1,500-2,000 miles. The piston rings do not properly seat against the cylinder walls, allowing oil to pass into the combustion chamber. The issue is exacerbated by the use of 0W-20 oil specified by GM. There is no visible external leak — the oil is burned internally and exits through the exhaust.

    This issue also affects: Buick LeSabre, Buick Park Avenue, Buick Cascada

    Common Symptoms

    • Oil level low between oil changes
    • Need to add 1+ quart every 2,000 miles
    • No visible oil leaks under vehicle
    • Blue-grey smoke from exhaust on hard acceleration
    • Oil smell from exhaust

    How to Fix

    Monitor oil level at every fuel stop and top off as needed with 0W-20 or 5W-30 synthetic oil. GM considers up to 1 quart per 2,000 miles "acceptable," but an oil consumption test at the dealer can document excessive use for warranty claims. For out-of-warranty vehicles, switching to a slightly heavier 5W-30 oil can reduce consumption. Severe cases require piston ring replacement ($2,000-$3,500). An Italian tune-up (sustained highway driving at higher RPM) can temporarily help by burning carbon off the rings.

    On the 2013-2016 Chevrolet Malibu 2.5L Ecotec, the 2013-2016 Malibu with the 2.5L Ecotec engine uses the GM 6T40 6-speed automatic transmission that develops a pronounced shudder during light acceleration in the 25-45 mph range. The torque converter clutch wears prematurely, causing slippage and vibration that feels like driving on rumble strips. Harsh 1-2 and 2-3 shifts are also common. The 6T40 is sensitive to fluid condition and the issue worsens rapidly if the fluid is not changed on schedule.

    This issue also affects: Buick Enclave, Buick Encore GX, Buick Regal

    Common Symptoms

    • Shudder or vibration at 25-45 mph under light throttle
    • Harsh 1-2 and 2-3 upshifts
    • Transmission hesitation or delayed engagement
    • Rumble strip sensation during gentle acceleration
    • Shudder disappears under hard acceleration

    How to Fix

    Perform a full transmission fluid exchange with ACDelco DEXRON VI ATF — a drain-and-fill three times (drive 500 miles between each) is most effective. If fluid change alone does not resolve the shudder, the torque converter needs replacement ($800-$1,500 including labor). GM released TCM software updates that modify shift points to reduce harsh shifting — ask the dealer for the latest calibration. Avoid aggressive driving until the issue is resolved, as continued torque converter slippage generates damaging heat.

    On the 2016-2024 Chevrolet Malibu, the 2016+ Malibu with the 1.5T engine uses a GM/Ford co-developed 9-speed automatic (9T50) that can exhibit shudder, harsh shifts, and delayed engagement. The 9-speed is sensitive to fluid condition and requires proper DEXRON HP fluid. GM has released multiple TCM calibration updates. The 2.0T Malibu uses a different 9-speed (9T65) with similar but less frequent issues.

    This issue also affects: Buick Encore GX, Buick Envision, Buick Regal

    Common Symptoms

    • Shudder at light throttle 25-50 mph
    • Harsh 1-2 and 3-4 shifts
    • Delayed engagement from Park to Drive
    • Hunting between gears on hills
    • Hesitation on acceleration

    How to Fix

    TCM software update at dealer is first step. Fluid exchange with Mobil 1 LV ATF HP can improve shift quality. For persistent shudder, valve body replacement may be needed.

    On the 2008-2019 Chevrolet Malibu, sunroof-equipped Malibus drain through a trough around the glass panel with four hoses — the front pair routed down the A-pillars and out into the wheelhouse area, the rear pair down the C-pillars. Two distinct failures are documented by owners who have traced them: the hoses clog with pollen, needles and roof grit, and — the one that surprises people — the hose simply falls off its nipple at the corner of the sunroof module and hovers loose behind the trim, dumping every bit of roof water directly into the headliner and down the pillar. The result is a soaked driver's or passenger's front and rear floor, a stained headliner, and a persistent musty smell. On this platform the floor is where GM put connectors and, on some builds, modules, so a long-running leak produces corrosion-driven intermittent electrical faults that get chased for months before anyone finds the water. Reported across the seventh, eighth and ninth generations.

    Common Symptoms

    • Wet carpet on the driver's or passenger's front or rear floor
    • Water dripping from the headliner or overhead console
    • Water running down the A-pillar trim after rain or a car wash
    • Musty or mildew smell in the cabin
    • Windows fogging persistently
    • Intermittent electrical faults traced to corroded floor connectors

    How to Fix

    Pour water into the sunroof trough at each corner and confirm it exits at the wheelhouse. Where it does not, clear the hose with low-pressure compressed air (under about 35 psi) or by feeding a length of heavy string-trimmer line or a bicycle brake cable down the tube — never use a rigid rod or high pressure, which splits the hose. If water pours into the headliner immediately, pull the A-pillar trim and check whether the hose has come off the module nipple; the durable fix is to refit it with a short hose extender and a clip so it cannot back off again. Dry the carpet and jute completely, and inspect underfloor connectors for green corrosion before signing off. There is no recall; expect $100-$300 at a shop for drain service, more if trim removal and drying are needed.

    On the 2008-2024 Chevrolet Malibu, the trunk latch mechanism on the Malibu fails due to a worn release cable, broken latch spring, or faulty trunk release actuator motor. Owners report the trunk will not open via the key fob, interior button, or the trunk release button on the lid. In some cases, the trunk will not latch closed and pops open while driving. Water intrusion into the latch mechanism accelerates corrosion and failure, especially in northern salt-belt states.

    Common Symptoms

    • Trunk will not open from key fob or button
    • Trunk pops open unexpectedly while driving
    • Trunk release button clicks but trunk does not open
    • Have to slam trunk multiple times to latch
    • Grinding noise from trunk latch area

    How to Fix

    Replace the trunk latch assembly ($50-$150 for the part) and inspect the release cable for fraying or binding. Labor is typically 1-2 hours ($100-$200). If the trunk will not open at all, access the latch through the rear seat pass-through (fold down the center armrest) and manually release it. Lubricate the latch mechanism with white lithium grease after replacement to prevent future corrosion. Check the trunk seal for damage that may be allowing water into the latch area.

    On the 2008-2020 Chevrolet Malibu, the A/C compressor clutch on the Malibu fails due to a burned-out clutch coil, worn clutch plate, or bearing failure in the compressor pulley. When the clutch fails, the A/C blows warm air because the compressor cannot engage. A squealing or grinding noise from the serpentine belt area is common before total failure. The compressor clutch can also seize, which will shred the serpentine belt and cause a loss of all belt-driven accessories (alternator, power steering, water pump).

    This issue also affects: Buick Enclave, Cadillac XTS, Chevrolet Camaro

    Common Symptoms

    • A/C blows warm air
    • Squealing or grinding noise from engine belt area
    • A/C cycles on and off rapidly
    • Burning smell from engine bay when A/C is on
    • Serpentine belt shredding or falling off

    How to Fix

    On some models, the A/C clutch assembly can be replaced independently ($100-$200 for parts, $200-$400 labor) without replacing the entire compressor. If the compressor itself has failed internally (metallic debris in the system), the entire compressor must be replaced along with the receiver/drier, expansion valve, and a system flush ($800-$1,500 total). Always evacuate and recharge the system with the correct amount of R-134a refrigerant after any compressor work.

    On the 2008-2019 Chevrolet Malibu, on the Malibu, especially the 2008-2012 2.4L Ecotec, P0128 is overwhelmingly caused by the engine thermostat sticking open. These thermostats fail as their internal rubber seal deteriorates, so coolant flows through the radiator constantly and the engine never reaches the calibrated operating temperature within the expected time after a cold start. The ECM detects the temperature shortfall and sets P0128. A low coolant level or a faulty coolant temperature sensor can mimic it, but the stuck-open thermostat is by far the most common root cause.

    This issue also affects: Buick Encore GX, Cadillac Allante, Cadillac Catera

    Common Symptoms

    • Check engine light
    • Heater blows lukewarm or cold air
    • Temperature gauge reads low or never reaches normal
    • Reduced fuel economy
    • Longer time to warm up in cold weather

    How to Fix

    Verify coolant level and confirm the ECT sensor reads accurately, then replace the thermostat and gasket (ACDelco 131-158 on the 2.4L). Use an OEM/ACDelco thermostat — cheap aftermarket units frequently fail to regulate and leave the code active. Refill and bleed the cooling system, then confirm the engine reaches full operating temperature.

    On the 2016-2020 Chevrolet Malibu, ninth-generation Malibus with the 8-inch MyLink screen suffer a well-reported blank-display failure: the screen goes completely black while audio continues playing, which means the head unit is alive and only the display path has dropped out. With the screen dead the owner loses the backup camera image, navigation, climate readouts on screens that route them there, and any ability to change source or station. Forum diagnosis converges on two hardware causes rather than a software bug — a failing or intermittently seated LVDS cable between the display and the Human Interface Unit behind the dash, and failure of the HMI module itself. It is not a fuse: pulling fuse 42 to force a hard reboot revives it temporarily on some cars, which is why owners chase it for months. The loss of the backup camera image makes this a functional safety concern, not just an infotainment annoyance.

    Common Symptoms

    • Infotainment screen completely black while the radio still plays
    • Backup camera image does not appear when reversing
    • No response to touch on the display
    • Screen returns briefly after a restart then goes black again
    • Cannot change radio source or station

    How to Fix

    Try the documented soft resets first — hold the volume knob and the Home button together for about ten seconds, or shut the car off, open and close the door without locking, and let it sleep for five or more minutes. If the screen returns and then fails again, the fault is hardware: pull the trim and reseat the ribbon/LVDS cable between the display and the Human Interface Unit — multiple owners report a permanent fix from simply reconnecting a loose or marginal cable, and others from replacing the cable. Where reseating does not hold, the display assembly or the HMI module is replaced; dealer parts pricing puts this in the $600-$1,200 range out of warranty. No recall exists, but check for any open infotainment software update at the same visit.

    On the 2016-2023 Chevrolet Malibu, on the ninth-generation Malibu the shifter assembly reports park position to the body control module through a set of small internal microswitch contacts. Over time the contacts spread, corrode or drift out of position, so the BCM never sees a valid park signal. The cluster displays 'Shift to Park' with the lever fully in P, the vehicle refuses to shut down normally, the interior lights and accessory bus stay awake, and the 12V battery is flat within a day or two. GM documented the condition in service bulletins and the diagnostic is DTC B000A, 'Park Switch — Shift Lever Position Not Plausible.' Owners across 2016-2023 Malibus report it, and a 2020 class action against GM named the Malibu alongside the Traverse and Acadia for the same shifter design. Note this is unrelated to the earlier shift-cable rollaway recalls on the 4-speed cars — the failure here is an electrical position switch, not a mechanical cable.

    Common Symptoms

    • 'Shift to Park' message displayed with the lever already in Park
    • Engine will not shut off with the start button
    • Interior and dome lights stay on after exiting
    • Dead 12V battery overnight or after a day parked
    • Message clears intermittently after re-selecting Park

    How to Fix

    Diagnose with a scan tool for B000A and inspect the park switch terminals inside the shifter assembly. Where the terminals are spread or damaged the entire shifter (transmission control) assembly must be replaced — GM's bulletin does not authorize repairing the individual contacts. Some owners get temporary relief by cycling the lever firmly through the gates or by cleaning the contacts, but it returns. Cars still inside the powertrain or bumper-to-bumper warranty have had it covered at no charge; out of warranty the assembly plus labor typically runs $400-$800. There is no NHTSA recall for this condition. Disconnect the battery negative terminal if the car will sit, to avoid a dead battery.

    What you need to diagnose it

    The repair instructions explicitly call for reading stored codes. Use a scanner that can read the named code families before choosing a repair.This issue involves B codes, which a basic engine-code reader cannot see.The recommended scanner supports these code families; confirm your exact year, model and module coverage before buying.
