    Drivers of the car pulled out of a plaza without blinker and almost ran into our vehicle. Passenger and driver continued to harass and make rude comments whenever they pass by us. And we felt very offended.

    My 2021 Nissan Sentra has experienced multiple false Automatic Emergency Braking (phantom braking) events where the vehicle suddenly applies the brakes despite there being no vehicle, pedestrian, or obstacle in its path. This issue occurred before and after my vehicle was serviced by AutoNation Nissan Chandler on June 12, 2026. Despite recent dealership service, the problem continues to occur. The unexpected braking creates a serious safety hazard because it can cause the vehicle to slow or stop unexpectedly in traffic, increasing the risk of a rear-end collision or other accident. I am also concerned that these repeated sudden braking events may be causing excessive stress or premature wear to vehicle components such as the engine mounts, suspension, and struts. Vehicle Information: Year: 2021 Make: Nissan Model: Sentra Mileage: Approximately 139,659 miles I am submitting this complaint because I believe this recurring phantom braking issue is a significant safety concern that should be investigated.

    The scope of repair required fixing a recalled tie rod that suffered a catastrophic failure, which directly caused the vehicle’s ADAS, Advanced Emergency Braking (AEB), and collision detection systems to crash. Berman Nissan promised a legally compliant, safe repair but breached this agreement by returning an unsafe vehicle, failing to road-test the steering component (verified by identical check-in/out mileage), and intentionally scrubbing trouble codes to conceal active safety failures. Staff explicitly refused all safety assistance, failed to secure my signature on any authorization paperwork from tow to pick-up, and Nissan corporate stated they were 'not legally required' to resolve the hazards. Service personnel stonewalled the issue, and management only escalated the matter to Service Director Mark Yalda after I disclosed I possessed concrete video proof of the identical mileage and unsigned invoices.

    Alternator needed replacement Front windshield needed replacement Unfortunately this kicked off the malfunction warning. All Nissan can say is it’s the ADAS 2 controller. They are unable to determine part numbers. However the alternator and windshield replacement kicked off the malfunction warning.

    Several issues since purchasing vehicle. The front collision sensor malfunction. Came to an abrupt stop several times while on the freeway due to failed sensor. Narrowly avoided major collisions. Also, have had to replace batter every year along with brakes and tires. My suspension is awful. The brakes are crap and have consistently had to address worn tires in one side. Electric panel shit off and key fob malfunctions. So many issues and so much unnecessary repairs with no real results

    Hello, I am reporting a steering-related issue involving the inner tie rods on my 2021 Nissan Sentra. Nissan previously issued safety recall campaign PM985 for bent inner tie rods on certain Sentra vehicles from the same model year. Two separate repair facilities inspected my vehicle and confirmed problems involving the inner tie rods and steering system components. No warning lamps or dashboard messages appeared prior to the issue being identified. Although my VIN may not currently be included in the recall population, my vehicle is experiencing a similar issue involving the same steering-related component identified in recall PM985. Because tie rods are directly related to steering control and vehicle stability, this issue raises concerns about driving safety. I am submitting this complaint so the issue can be documented and reviewed in case similar failures are occurring outside the current recall population.

    The door swung open while in drive, once was able to pull over and close it never opened back up due to a faulty door actuator. This was the third time the door had been “fixed”.

    The contact owns a 2021 Nissan Sentra. The contact stated that while driving approximately 15 MPH, the parking braking independently activated. The failure occurred a second time, and the parking brake unintendedly activated. There was no warning light illuminated. On the third occasion, while driving approximately 45 MPH, the parking brake activated unintendedly, causing the vehicle to stop abruptly, nearly causing a crash with another vehicle. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was 13,414.

    The infotainment/radio system in my 2021 Nissan Sentra intermittently reboots and produces static. When this happens, the backup camera freezes or shuts off completely. This has occurred while I was actively reversing, causing a sudden loss of rear visibility. The screen either goes black or restarts, making the backup camera unavailable. This is a safety concern because the backup camera is required for safe reversing, and the failure happens without warning. The issue occurs repeatedly and is not driver-related. The problem appears to be related to the head unit malfunctioning, which disables the backup camera system.
