What owners say
6
Overall
Sentiment is broadly positive, with the Mazda 6 consistently praised for its reliability, longevity, and driving dynamics. Long-term owner reports frequently highlight the vehicle's ability to reach high mileages (e.g., 250,000 miles, 377,000 miles) with minimal major issues when properly maintained. The car is commended for its handsome design, well-regarded interior quality in its class, and a driving experience often described as more engaging than key competitors like the Toyota Camry and Honda Accord.
Best version to buy
Insufficient owner data available to declare a single "best" trim or version across all generations. Feedback is divided by powertrain preference.
Known issues
- ⚠Thin paint / paint chipping and fading: noted on multiple generations, particularly older models. Frequency: recurrent.
- ⚠Rust issues: especially on heat shields and exhaust components, causing rattles; mentioned on pre-2014 models and some later examples. Frequency: recurrent.
- ⚠Steering wheel vibration / shake at highway speeds (55-65 mph / 89-105 km/h): often attributed to tire balance rather than mechanical fault. Frequency: isolated.
Altima
Overall
Extremely negative sentiment regarding long-term reliability, dominated by widespread and severe criticism of the Continuously Variable Transmission (CVT). The CVT is described as a fundamental design flaw leading to premature failure, often between 80,000 and 150,000 miles, with replacement costs cited around $4,000. This issue is so pervasive it has spawned multiple class-action lawsuits, particularly for models from the 2010-2020 period.
Best version to buy
Insufficient owner data available to identify a consensus "best" model year or trim. Isolated positive anecdotes reference older models (e.g., 2002 Maxima, pre-2010 Altimas) with traditional automatic transmissions, but no specific Altima generation or trim receives repeated endorsement.
Known issues
- ⚠CVT transmission failure: Catastrophic failure requiring full replacement, often between 80,000-150,000 miles; symptoms include jerking, shuddering, loss of acceleration, lurching at low speeds, and inability to rev beyond a certain RPM.
- ⚠CVT-related problems (general): Whining noise, rubber band effect, laggy throttle response, and general concerns about long-term durability. Frequency: very frequent.
- ⚠Engine issues (various): For 2019-2021 models with the 2.0L VC-Turbo engine, a manufacturing defect in engine bearings can lead to catastrophic engine failure, knocking noises, loss of power, and potential fire, as detailed in a NHTSA reca…
