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.

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 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.
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.
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.
NHTSA recall 26V023000 and Nissan campaign PD185 cover certain 2025 Altima vehicles. Improperly welded door strikers may break and allow a door to open while the vehicle is moving, creating a noncompliance with FMVSS 206 and an injury risk.
Common Symptoms
VIN checked for 26V023000/PD185
door latch engagement checked
dealer striker replacement confirmed
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. Do not buy a striker, latch, fastener or body repair from this page; VIN eligibility and the recall 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.
The electronic steering column lock can malfunction, preventing the car from starting. The system fails to release the steering lock even with the correct key. This is a safety feature that can strand drivers.
Common Symptoms

Key recognized but won't start
Random no-start conditions
How to Fix
Steering column lock actuator replacement required. Nissan issued service campaigns for some model years. Some owners have had the system disabled. Check for recalls or service campaigns for your VIN.
Owner tips & cautions
TipThe electronic steering column lock can malfunction, preventing the car from starting.

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.

High Confidence4,500 owner reportsLast reported by owners Feb 2024Reviewed Feb 2026
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.

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
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

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 A/C compressor can fail, particularly on vehicles in hot climates. When the compressor fails internally, it can contaminate the A/C system with debris. Clutch failure is also common.
Common Symptoms
A/C blows warm air
Clicking when A/C engages
A/C clutch not engaging
Loud noise from compressor
Refrigerant leak
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.

Altimas in this period frequently suffer from failing crankshaft position sensors and camshaft position sensors, especially on the 2.5L and 3.5L engines. Owners report intermittent stalling at stops or while driving, extended cranking, sudden no-start conditions, and check-engine lights. Nissan issued service information and many owner reports describe repeat failures with cheap aftermarket sensors.
Common Symptoms
engine stalls while driving
intermittent no-start
long crank time
tachometer drops to zero
check engine light
hard restart when hot
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.

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.
Some Altima owners experience unexplained battery drain, resulting in a dead battery after sitting for a few days. Various electronic modules not going to sleep properly can cause excessive draw. The Intelligent Key system may also be a factor.
Common Symptoms
Dead battery after sitting
Battery won't hold charge
Frequent jump starts needed

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.

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.
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%.

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.

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.

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.

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.

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.

Owner tips & cautions
TipDo not assume tire noise; many owners chased alignment and tire issues before confirming the bearing by loading the car side-to-side during a road test.
TipIf an ABS light appears with bearing noise, inspect the hub tone ring/sensor signal before replacing separate ABS components.
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.

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.
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.

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.
