2021 Nissan Altima Driver Assist & ADAS Problems

The Automatic Emergency Braking (AEB) system in my 2021 Nissan Altima SR frequently malfunctions. The forward radar sensor, located behind the front grille, becomes easily obstructed by normal road dirt or weather conditions. When this happens, the system falsely detects obstacles and engages braking or gives collision warnings even when the road ahead is clear. This places my safety and the safety of others at risk because the vehicle can suddenly slow or stop without cause, increasing the chance of a rear-end collision. To avoid false activations, I must disable the AEB system every time I drive, which defeats the purpose of having this federally mandated safety feature. The problem is ongoing and repeatable. Warning lights and collision alerts appear when the sensor is dirty or misreading conditions. Nissan dealerships have acknowledged this issue through Technical Service Bulletins, but there is no permanent fix and no recall. The malfunction has not been resolved by the manufacturer and continues to pose a safety hazard.

[XXX] slams on brakes going in reverse for no reason, I wish there was a way to disconnect this to me it's more of a safety issue.

front impact radar malfunction. The light on the console would come on intermittently. I took the car to the dealer and they said the front radar was defective and they replaced the front radar. Not even two months have passed and the light is back on. This can cause your car to suddenly stop causing you to be rear ended because the car thinks you are in danger. It affects the automatic emergency braking system. This car is brand new and just went over 10,000 miles. It recently had it's first service and now I have to take it back and get it checked again.

I purchased my car from Sheehy Nissan of Waldorf on November 1, 2022. At the time of purchase the vehicle had 38,709 miles. It reportedly had one previous owner and was originally titled on 3/11/2021. From the day I purchased this vehicle I have had trouble with the automatic emergency braking system. I am experiencing sudden unintended brake activation in various situations. I have experienced the emergency braking system activating when I am driving at high speeds (60-70 mph) with nothing in front of me. I have had it automatically brake when I am in traffic maintaining safe distances and speeds. I have experienced it braking when I have been leaving a parking garage - again with nothing near or around my vehicle. When this occurs, it is when the warning lights turn off. So, it is completely random and unpredictable. The warning light turns on 100% of the time I drive the vehicle. I took my car to Sheehy Nissan of Waldorf for repair of this issue on 3/28/23, 6/13/23, and 8/3/23, but, to date, they have been unable to correct the problem. Most recently (8/25/23) I was given an estimate of an additional $1,977.43 for a 4th attempt to fix this problem. I met with the Service Manager, [XXX] , on 8/28/23 to discuss the matter. He said he would talk to the Nissan area rep and their warranty rep and get back to me. Two days later he responded that the area rep offered to cover 40% of the repair cost, making my cost $808.96 for the 4th repair attempt. As you are aware, this is a known issue with this vehicle and many other Nissan models. The NHTSA started an investigation into Nissan regarding this issue in September 2019. There have been multiple lawsuits and class action suits against Nissan for this same problem, yet they continue to sell these vehicles without fixing the problem or issuing a recall.

RE: Formal Demand for Vehicle Repurchase/ Buyback due to Critical Safety Defect- Vehicle Breaking on Its Own While Driving I am writing to file a formal safety complaint and to demand immediate corporate intervention regarding an extremely dangerous mechanical/ADAS defect in my vehicle that Nissan has failed to repair since I purchased it in 2021. My Nissan Altima has serious, ongoing safety issues where the vehicle will unexpectedly and aggressively apply the brakes on its own while I am driving, including on highways and regular roads. This defect happens without my input, without warning, and creates a major risk of being rear-ended, losing control of the vehicle, or causing a serious accident. This issue is Not minor. It is a life-threatening malfunction that makes the vehicle unsafe to operate. I have taken the vehicle to authorized Nissan dealerships for diagnosis and repair on multiple occasions: Repair Dates 2021-2025 at Passport Nissan of Alexandria 150 S Pickett St Alexandria, VA Location Despite these visits, the problem continues. Nissan’s failure to diagnose or repair this critical break/self-braking issue over several years constitutes: •Failure to remedy a known safety defect •Breach of warranty •Violation of consumer protection laws •Negligence regarding driver and public safety A vehicle that breaks on its own, especially at highway speeds – is not safe, not reliable, and not roadworthy. Because Nissan has had more than a reasonable opportunity since 2021 to correct this defect and has failed to do so, I am demanding that Nissan: 1.Buy back the vehicle at an amount equal to the remaining loan balance. I do not want to do any upgrade trade ins. This situation has gone on for years and the vehicle is now a clear danger to me and the public and my two minor children who ride in the car with me. I am requesting immediate action and a good-faith resolution.
