2009 Nissan Altima engine problems
severe 40 complaints filed with NHTSA · avg repair $3,100 · see engine across all vehicles →
Owners have filed 40 engine complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
The failure pattern owners describe
Exhaust manifold cracks dominate these complaints. Owners report manifolds failing multiple times within months, sometimes even after warranty replacement. The cracks leak carbon monoxide directly into the cabin through exterior HVAC vents, causing nausea, drowsiness, and documented CO poisoning symptoms. One owner had fire department confirm the leak; another was pregnant and concerned for a young asthmatic child riding constantly in the car. Despite Nissan recalling 2007–2008 models for identical failures (NTB12-092, PC130/PC131), 2009 VINs are frequently excluded—owners say Nissan refuses coverage citing VIN parameters.
Engine stalling under load is a second major failure pattern. Cars shut down completely while driving on expressways, forcing emergency pull-overs. Some restart after delay; others require towing. Owners were billed $500–$1,200 for O2 sensor or mass air flow sensor replacement, only to face the same failure months later.
Cylinder misfire and carbon buildup recur even after spark plug, coil, and fuel injector replacement. The condition mirrors a 2007–2008 recall but is not covered for 2009 models. Electronic steering column locks fail, trapping owners out of vehicles—Nissan knows the part is defective (they replaced it with a 2013 component design) but won't recall it or cover the ~$1,000 repair outside warranty. Heat shield rattling persists despite multiple dealer repairs. A few narratives report catastrophic engine fires and crankshaft fractures at low mileage.

Failure modes owners describe
Cracked/leaking exhaust manifold
Manifold develops cracks and leaks, sometimes repeatedly within months. Owners report replacement multiple times under warranty or out of pocket. Carbon monoxide seeps into the cabin via exterior HVAC intake vents, causing nausea, drowsiness, and potential poisoning risk. One narrative documents fire department confirmation of CO leak.
When: varies; 100,000–150,000 miles commonly cited; some as early as warranty expiration
Symptoms owners cite: loud gritty noise under hood; exhaust/gas smell inside cabin; nausea and fatigue while driving; check engine light; visible cracks in manifold
Repairs/costs cited: Manifold replacement; one owner replaced manifold twice in 3 months under warranty; another needed complete exhaust system. Costs cited: $400–$2,132. One narrative indicates third replacement in one year.
Recalls/TSBs owners mention: Nissan recalled 2007–2008 models (NTB12-092, NTB13-056a, PC130/PC131) but 2009 VINs often excluded from recall eligibility. Some owners denied lemon buyback claims. Nissan refused coverage citing VIN exclusion from recall parameters.
Engine stall under load
Engine shuts down completely while driving, sometimes at highway speeds, forcing coasting to rest areas or emergency pull-overs. Failure to restart on first attempt is common. Towing required in several cases.
When: 100,000–110,000 miles; one case at 65,000 miles
Symptoms owners cite: complete engine shutdown while driving; loss of power; multiple warning lights (check engine, battery, oil, brake); engine restart delay
Repairs/costs cited: Repairs varied by diagnosis: O2 sensor replacement (~$1,200), mass air flow sensor (~$500), crankshaft replacement (~$400), crank/cam shaft replacement, steering column sensor repair. Multiple stalls on same vehicle suggest recurring issue.
Recalls/TSBs owners mention: No recalls explicitly covering 2009 stall events noted in narratives. Nissan told owners stalls were outside recall scope for their VINs.
Cylinder misfire with carbon buildup
Cylinders misfire persistently. Carbon deposits on valves and catalytic converter breakdown occur. Ignition coil, spark plugs, and fuel injector replacement do not resolve misfire. Condition cited as recall issue in 2007–2008 but not applied to 2009.
When: 59,000 miles documented; 120,000 miles mentioned in other cases
Symptoms owners cite: rough idle; misfire during acceleration; check engine light with misfire codes; fuel smell; performance hesitation
Repairs/costs cited: Dealer initially replaces ignition coil, spark plugs, fuel injector, and fuel line flush without resolution. Long engine assembly and exhaust manifold replacement required in one case.
Recalls/TSBs owners mention: Recall NTB13-056a, Campaign ID PC131 issued for 2007–2008 but not extended to 2009 despite identical failure modes reported by owners and technicians.
Electronic steering column lock (ESCL) failure
Keyless push-to-start and steering wheel lock mechanism malfunction, rendering vehicle unable to start. Part is proprietary; independent locksmiths cannot bypass. Vehicle enters anti-theft 'hijack mode.' Nissan has replaced part with 2013-model component, suggesting awareness of defect.
When: varies; one case within 6 months of 'extended warranty' expiration; 110,000 miles documented
Symptoms owners cite: car will not start; steering wheel locked; push-button start fails to engage; anti-theft system activation
Repairs/costs cited: Part replacement only available at Nissan dealership. Cost cited: $899–$1,200. Owner notes Nissan replaces with different part number from 2013 Altima, indicating known design flaw.
Recalls/TSBs owners mention: No recall issued. Nissan refuses coverage if part fails outside limited warranty. Acknowledged defect by using updated part number in repairs but will not retroactively replace or extend warranty.
Intake manifold fracture
Intake manifold develops cracks or fractures, sometimes recurring even after replacement. Loud noise and fuel smell accompany failure. Some narratives indicate failure recurs two or three times.
When: 120,000–171,000 miles
Symptoms owners cite: loud abnormal noise from under hood; fuel fume smell; hesitation to accelerate; check engine light
Repairs/costs cited: Replacement required; one narrative cites three separate repairs for same failure. No cost data provided by owners.
Recalls/TSBs owners mention: No manufacturer response or recall cited in these narratives.
Heat shield rattle/popping noise
Loud popping or rattling sound occurs under the car after engine warms or when idling. Initially misdiagnosed as normal cooling. Dealer replacement of heat shield rivets with larger ones and exhaust system work temporarily reduce noise but problem recurs. Concern expressed about metal fatigue from expansion/contraction.
When: ongoing for 16 months in one case; 6+ months in another
Symptoms owners cite: loud popping noise after warm idle; noise recurring after repair; loud rattling from undercarriage
Repairs/costs cited: Heat shield reworked with larger rivets; serpentine belt, tensioner, and exhaust system replaced without permanent fix. Recurring issue requires multiple dealer visits.
Recalls/TSBs owners mention: Nissan engineers contacted in one case; no permanent resolution provided. Problem recurs despite multiple reworks.
Keyless start system leaves engine running
Push-button start/keyless ignition fails to require re-engagement of button to keep engine running. Driver can exit vehicle with engine still idling, creating fire and exhaust risk, particularly in garages.
When: observed early in ownership
Symptoms owners cite: engine continues running after driver exits; no automatic shutoff; no warning chime or visual alert
Repairs/costs cited: No repair mentioned; design flaw in safety feature.
Recalls/TSBs owners mention: No recall or design change noted.
Engine fire during operation
Air filter housing catches fire while driving, air filter melts. Stalling and smoke from hood reported in separate case with complete front-end fire. Both represent catastrophic thermal/electrical failure.
When: 48,000 miles in one case; timing unknown in other
Symptoms owners cite: smoke from hood; fire visible under hood; air filter/housing damage; engine stall preceding fire
Repairs/costs cited: One case: air filter housing replaced (repair shop unable to diagnose cause). Other case: entire front end engulfed; owner escaped with child.
Recalls/TSBs owners mention: Manufacturer did not offer assistance; no recall issued per dealer feedback.
Crankshaft fracture
Crankshaft cracks or breaks, causing sudden engine shutdown mid-drive. One case reports fractured push rod puncturing engine block. Engine replacement required.
When: 38,385 miles; another case at 81,500 km (~50,000 miles)
Symptoms owners cite: sudden engine stall while driving; engine will not restart
Repairs/costs cited: Complete engine replacement required. Cost estimates: ~$400+ for crankshaft work; full engine replacement likely much higher. Owner notes similar recalls exist for 2002–2006 models but 2009 excluded.
Recalls/TSBs owners mention: VIN excluded from applicable recalls; Nissan refused coverage despite identical failure mode in earlier model years.
Oil consumption and piston ring wear
Engine burns excessive oil, requiring 3–4 quarts between scheduled changes. Piston ring degradation causes misfires and burnt-out spark plugs every 2 months.
When: not specified
Symptoms owners cite: low oil level between services; misfire on highway; burnt-out spark plugs
Repairs/costs cited: Frequent spark plug replacement; no major engine work cited.
Catalytic converter damage
Catalytic converter fractures or degrades, often in combination with other exhaust issues. Check engine light illuminates.
When: 150,000 miles in one case; 177,000 miles in another
Symptoms owners cite: check engine light; loud noise; performance loss; fractured converter
Repairs/costs cited: Replacement required but cost not cited in narratives. One vehicle was not repaired.
