2021 Nissan Sentra Collision Avoidance Problems

While driving on empty roads, your car's fuel economy warning light beeps and the automatic emergency braking system activates on its own. This has happened multiple times without any actual collision risk. The system may need recalibration or sensor inspection to prevent false emergency braking events.

The contact owns a 2021 Nissan Sentra. The contact stated while driving at an undisclosed speed, the automatic emergency braking system engaged while there were no nearby vehicles or pedestrians. The contact stated that the failure recurred several times while driving. Additionally, the contact stated that the message "System Malfunction" was displayed. The vehicle was taken to the dealer several times; however, the failure could not be replicated. The vehicle was not repaired. The manufacturer was made aware of the failure, but no assistance was provided. The failure mileage was approximately 200.

I brought this car in January 2023 and the Forward Emergency Braking keeps popping on while driving. There are zero cars that were in front of me. This is the 4th time this has happened. With the last 2 incidents happening within the last 24hrs . 10/21/23 & 10/22/23. This is issue that may cause accident.

1. Automatic Emergency Braking - System - System Failed /or Malfunctioned Car is available for examination (28,000 miles) 2. Collision alert sounded, with warning indicator (red bar with two white bars below), Emergency braking triggered (no apparent ABS, but driver felt the vehicle decelerate), stopped the vehicle, and turned the vehicle engine off (electrical systems remained on). The vehicle was traveling on a city street at approximately 35 MPH at a slight incline, at dusk. No signs, pedestrians, other vehicles, or signs within visible distance present in front of the vehicle, or on either side of the road. There were no obstruction, debris, speed bumps, trees or pot holes on either side of the road within visible distance in front of the vehicle. Injuries may have occurred if another car was closely following, or could not stop in time. 3. The problem has been reported to the Suntrup Nissan (dealer from whom we purchased the vehicle) and Nissan Consumer Affairs (case [XXX]). The Consumer Affairs representative did not seem to understand the problem (initially thought it was ABS)or safety concern though (she said we should not worry as the vehicle was under waranty). We are awaiting a call back from the dealer though. However, in searching for an explanation we saw similar issues reported by a law firm (LemonLawExperts.com) 4. Vehicle has not been inspected. 5. This was the first such incident we experienced in the car. Other than the warning alert during the incident, there was no indication of this problem. The car had been in for routine service about a month ago though. At the service I mentioned the radio spontaneously turning off while traveling in a parking lot, and then turning back on a minute or two later in the same parking lot. To our knowledge the only repair work was a faulty window switch that was replaced. “INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).”

The contact owns a 2021 Nissan Sentra. The contact stated that while his daughter was driving 35 MPH, the vehicle experienced phantom braking. No warning light was illuminated. The vehicle was not diagnosed nor repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 11,382.

I brought this car 1/28/2023. The car emergency brake or stop was activated for no reasons at all. There was zero objects in front of my bumper. This happened to me twice. Once in May 2023 and then again on the 4th of July 2023. I called the dealership on 1st incident in May 2023 and I was told that the brakes will be applied if the car thinks it’s getting ready to crash. This is very dangerous and can cause an accident if the emergency braking system is causing the car to stop for no reasons.

AEB SYSTEM ACTIVATED ON IT'S OWN, 3 TIMES RANDOMLY ,BRAKES SLAM ON FOR NO REASON WHILE DRIVING AT NORMAL SPEED. IT IS AVAILABLE FOR INSPECTION. IF THERE WAS A VEHICLE IN BEHIND ME THERE WOULD HAVE BEEN AN ACCIDENT. WE JUST TOOK IT TOTHE DEALSHIP TO HAVE THE SYSTEM CHECKED AND THEY COULD NOT FIND A PROBLEM.IT HAS NOT BEEN INSPECTED BY A MANUFACTURER OR OTHERS. NO WARNING LIGHTS OR SYMPTOMS PRIOR TO FAILURE. I CAN NO L,ONGER DRIVE THIS CAR WITH CONFIDENCE.

Intermittently the Automatic emergency braking system randomly engaging with no obstructions present.

I was driving at 55 mph this morning while taking my child to the bus stop when the emergency braking system kicked on out of nowhere almost causing me to lose control of the car. There were no vehicles in front of me or any obstruction that would have caused this to occur. The recall for the blind spot sensors has already occurred on this vehicle as well. It is a danger to not only myself but potentially other vehicles that could have been following me to have a vehicle abruptly stop like it did which in then endangered myself and my children.
