Nissan Altima Common Problems and Repair Costs

CVT Transmission Failure (2013–2018)

The CVT (continuously variable transmission) in 2013–2018 Altimas is the most significant known issue. Symptoms include shuddering during acceleration, hesitation, and eventual failure. CVT replacement costs $3,500–$5,500. Nissan extended CVT warranty to 10 years/120,000 miles on some years — verify coverage by VIN at any Nissan dealer before buying used. Change CVT fluid every 25,000 miles.

Timing Chain Stretch — QR25DE Engine (2002–2012)

The 2.5L QR25DE engine in 2002–2012 Altimas is prone to timing chain stretch, causing a rattling noise on startup and eventually P0011/P0014 codes. Timing chain replacement costs $900–$1,800. The fix is the same as prevention — regular full synthetic oil changes. Deferred oil changes dramatically accelerate chain wear on this engine.

Oil Consumption — QR25DE (2002–2006)

2002–2006 Altimas with the QR25DE engine can consume excessive oil between changes — sometimes 1 quart per 1,000 miles. Nissan issued a technical service bulletin but did not extend the warranty broadly. Check oil every fill-up on these model years.

Catalytic Converter Failures (Multiple Years)

Altima catalytic converters are also frequently targeted for theft due to their precious metal content. P0420 codes are common on higher-mileage Altimas. Converter replacement runs $800–$1,400.

Best Years to Buy

• Best: 2019–2022 (revised CVT, improved reliability)
• Good: 2016–2018 with verified CVT fluid history and warranty check
• Avoid: 2013–2015 CVT without extended warranty, 2002–2006 without oil consumption documentation
