On the 2002-2018 Nissan Altima, 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.

On the 2007-2018 Nissan Altima, 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.

On the 2002-2018 Nissan Altima, 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.

On the 2007-2018 Nissan Altima, 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 the 2007-2012 Nissan Altima, 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.
On the 2002-2012 Nissan Altima, 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.

Owner tips & cautions
TipIf the reservoir keeps dropping, inspect the rack boots and hose crimps before replacing the pump; many owners replaced noisy pumps only to find the real problem was a leak.
TipAfter any rack or hose repair, flush contaminated fluid out of the system to reduce repeat pump noise and seal wear.
On the 2002-2012 Nissan Altima, 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. Quality complete strut assemblies are widely available aftermarket.

On the 2002-2012 Nissan Altima, 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.

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.
On the 2007-2013 Nissan Altima, 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 2002-2021 Nissan Altima, 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 2007-2020 Nissan Altima, 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.

On the 2007-2018 Nissan Altima 3.5L VQ35DE V6, 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%.

Universal aerosol cleaner for hot-wire MAF elements; follow label directions and never substitute other solvent cleaners. Fitment/availability: Retailer inventory and add-to-cart live at review
On the 2007-2018 Nissan Altima, 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.

On the 2007-2012 Nissan Altima, 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.
On the 2002-2016 Nissan Altima, 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 2007-2018 Nissan Altima, 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.

On the 2002-2012 Nissan Altima, 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.
On the 2005-2012 Nissan Altima, 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.

On the 2007-2017 Nissan Altima, 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.

Genuine Nissan air-mix actuator 27732-AL610
2007-2012 Altima 2.5L or 3.5L; verify actuator location, HVAC configuration and VIN.
On the 2007-2018 Nissan Altima 2.5L QR25DE I4, 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.
