The Nissan Altima has long been a top-selling midsize sedan — offering a comfortable ride, spacious cabin, and fuel-efficient powertrains. But the Altima's CVT transmission has become one of the most discussed reliability concerns in the automotive world, and when it fails, the repair bill is substantial.

Common Nissan Altima Failure Points
CVT Transmission
The CVT (continuously variable transmission) is the Altima's most discussed reliability weakness. Nissan has used various CVT versions across generations, and failures — ranging from juddering and shuddering to complete breakdown — are well-documented, particularly on 2013–2018 models. Full CVT replacement costs $3,500 to $5,500.
Nissan faced multiple class-action lawsuits and extended warranty programs related to CVT failures in Altima and Sentra models. Despite Nissan's extended CVT warranty (covering some models to 84,000 miles), many owners are now beyond those limits and face full out-of-pocket replacement costs.
A/C Compressor
A/C compressor failure is a recurring issue across Altima generations. Replacement costs $900 to $1,700 depending on model year. If the compressor was seized and metal debris contaminated the system, a full system flush adds another $500–$800.
