Specs side by side
What owners say
626
Overall
Sentiment is mixed and heavily dependent on model year and powertrain. The vehicle is generally remembered as a practical, comfortable, and often reliable family sedan, with several owners reporting high mileage (e.g., 300,000 miles, 550,000 km) with proper maintenance. Positive recollections highlight its comfortable seats, smooth ride, and status as a loved and dependable daily driver.
Best version to buy
Insufficient owner data available to designate a specific model year or trim as the "best." However, strong implicit consensus indicates that models equipped with a manual transmission are vastly preferable due to avoiding the notorious automatic transmission failures. The V6 engine is mentioned as an available option, but no comparative reliability data between the 4-cylinder and V6 models is provided in the discussions.
Known issues
- ⚠Automatic transmission failure: very sluggish or hard shifting, failure to shift out of park, complete failure requiring rebuild, often at low mileage (e.g., 85,000 miles); flashing Overdrive (O/D) Off light is a common warning sign.
- ⚠Cooling system problems: persistent overheating, coolant leaks from the reservoir, suspected clogged radiators, thermostat failures; issues often exacerbated by using air conditioning. Frequency: very frequent.
- ⚠Electrical and sensor issues: intermittent turn signal failure, alternator/voltage regulator problems causing battery drain, rough idle and stalling linked to faulty sensors (MAF, O2), malfunctioning neutral safety switch.
Sentra

These failures are described as catastrophic, often occurring between 75,000 and 115,000 miles, with repair costs ranging from $3,000 to over $8,000.
Best version to buy
Insufficient owner data available to designate a specific "best" trim or model year. For the newest generation (2024+), the SV Premium trim is mentioned positively for its feature content.
Known issues
- ⚠CVT Transmission Failure (Pre-2024 Models): Catastrophic failure often between 75k-115k miles, characterized by shuddering, loss of acceleration, inability to move forward, loud whining, and complete breakdown.
- ⚠CVT Operational Problems (All Generations): Shuddering during acceleration, jerking when shifting between drive and reverse, rubber band effect, whining noise, and laggy throttle response. Frequency: very frequent.
- ⚠Intermittent Electrical & Starting Issues: Problems include cars that won't start (often related to brake pedal sensor/switch), random stalling while driving, and audio/power mirror systems failing intermittently with an audible click from…
