There are 2 owner-reported powertrain & transmission complaints for the 2023 Nissan Sentrain NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
The contact owns a 2023 Nissan Sentra. The contact stated that while the vehicle was parked in the driveway and shifted to park(P), the vehicle started to slowly roll backwards unexpectedly. While attempting to re-enter the vehicle to stop the vehicle, the contact was knocked to the floor by the driver’s side door. The contact sustained injuries to the knees, back, thighs, and a concussion. The contact received medical treatment and an appointment for an MRI was scheduled. The dealer was not notified of the failure. The manufacturer was not notified of the failure. The failure mileage was 75,300.
Upon purchasing the vehicle on December 21, 2024, I immediately noticed a delay in acceleration when pressing the gas pedal, particularly after the vehicle had been idling for some time. This delay creates a significant safety risk, especially in situations where quick acceleration is needed, such as merging onto highways or avoiding accidents. Additionally, the vehicle displays incorrect fuel mileage readings, leading to poor fuel consumption and inaccurate fuel gauge readings, further jeopardizing safety due to the potential misjudgment of remaining fuel. During the test drive with the service manager, he almost got into two accidents because of the delay in acceleration. He acknowledged that the issue was caused by the updated CVT transmissions and stated that it would be best to return the car. Despite this, the dealership was unable to fix the problem after multiple visits. I was advised to contact Nissan Consumer Affairs, who were aware of the delay in acceleration. However, after following up with Nissan, I was directed to file a complaint with the Better Business Bureau (BBB). The issue has been replicated by the service techs, two sales managers, the service manager, and the dealership owner. The service manager confirmed the acceleration delay during the test drive and recommended returning the vehicle due to its unsafe nature. This delay continues to pose a serious safety concern, and I am deeply concerned that it could lead to an accident if not properly addressed.
