What owners say
K5
Overall
Mixed to positive sentiment overall, heavily dependent on model year and powertrain. The vehicle is widely praised for its aggressive, eye-catching styling, comfortable and spacious interior, and strong value proposition with extensive standard technology and safety features. Owner satisfaction is high regarding the smooth ride, quiet cabin, and the Highway Driving Assist system.
Best version to buy
K5 GT with GT1 Package: This configuration is consistently highlighted as the most desirable. Owners praise the powerful 2.5L turbo engine, the engaging DCT transmission, and the comprehensive feature set of the GT1 package, which includes ventilated seats, a premium Bose sound system, and advanced safety tech.
Known issues
- ⚠Electrical/Infotainment glitches: Includes infotainment screen freezing, frequent Bluetooth/CarPlay disconnections, slow system response, and various unexplained electrical gremlins. Primarily associated with 2021-2022 model years.
- ⚠Powertrain Concerns (Pre-2025 GT-Line): The 1.6L turbocharged engine is described as underpowered and sluggish, especially from a stop.
- ⚠Traction Limitations (GT Trim): Front-wheel-drive GT models experience significant wheel spin and torque steer under hard acceleration due to the powerful 2.5T engine and lack of a limited-slip differential. Frequency: recurrent.
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…
