Nissan Altima phantom braking problems

Filed Apr 9, 2026 · NC · crash

I am reporting a potential unintended automatic emergency braking event involving a 2025 Tesla Cybertruck. On 23Mar2026, at approximately 40 mph, I was traveling behind a Tesla Cybertruck on a public roadway. There were no visible obstacles, hazards, or debris in the roadway that I observed. The Cybertruck suddenly and aggressively braked without warning. The abrupt deceleration appeared inconsistent with road conditions and is consistent with what is commonly described as “phantom braking.” As a result of the sudden stop, I was unable to avoid a collision with the rear of the vehicle despite maintaining a reasonable following distance. After the impact, the Cybertruck initially left the scene, stating they were unaware a collision had occurred. No debris or roadway hazard was documented at the scene in the police report (FVPD report #2026-00777). The other driver later indicated a plastic bag may have triggered the vehicle’s emergency braking system. I am submitting this report as a potential safety issue involving unintended or inappropriate automatic emergency braking behavior.

The system malfunctioning is the front sensor braking. My safety and others were put at risk with this because multiple times my car has braked me and or completely stopped me because it’s malfunctioning , it happens while I am on a busy street and someone even almost rear ended me because my car braked out of nowhere. It’s called “Phantom Braking”. No, the problem has not been confirmed by dealer became they stopped answering. I took it to the manufacture but they want to charge me too much. Yes and it first appeared Feb 2nd , a day after I bought the car. So at first it will aggressively brake me and I can tell when it’s going to start braking me because this loud scratching/grinding noise appear .. the noise sounds like it’s coming from the bottom and I can feel it vibrating my car when I relax my feet on the brakes or the floor. But as soon as that noise comes on then the car starts braking me and sometimes it will cause the engine to stall and then the car will stop driving completely while im on the middle of traffic.

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. 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 & originally they told me it should be under warranty & when they spoke to the dealership they said it did not qualify under the warranty nor the extra insurance purchased & i'd have to come out of pocket for repairs. A vehicle that breaks on its own, especially at highway speeds – is not safe, not reliable, and not roadworthy. This situation has gone on for years and the vehicle is now a clear danger to me and the public and my three minor children who ride in the car with me. I am requesting immediate action and a good-faith resolution.

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.

The contact owns a 2024 Nissan Altima. The contact stated that while his son was driving 35 MPH, the vehicle experienced Phantom braking. The contact stated that his son depressed the accelerator pedal and the vehicle continued to drive with no additional failure. The vehicle was taken to the dealer where the failure was diagnosed as a sensor with the Automatic Emergency Braking (AEB) system and a fractured bracket. The AEB sensor was replaced; however, the contact was waiting for the bracket to be replaced because the bracket was on backorder. The contact stated that the AEB system was deactivated as per the Service Manager's advice since the dealer was waiting for the bracket to be received. The contact provided part number: 28438-5FA6A (Sensory Assemble DIST) and part number: 62310-9HF8E (Grille Radiator). The manufacturer was not notified of the failure. The approximate failure mileage was 21,000.

The forward emergency braking system periodically will engage with no reason. I did not record the first date this happened. It was in July 2021. This first happened not long after I purchased the car last year on the interstate in heavy traffic with low speed and nothing close enough to set it off. Sometimes just the emergency light will just appear and disappear quickly and sometimes it comes on and the brakes go on. The dealer service and the regional technician has inspected it a few times and could find no error but it only happens sporadically. I checked recently and there is a class action suit against Nissan for the same problem in Tennessee. There seems to be the same problem with other models from 2019 to present.

The car regularly automatically slams on the brakes for no reason when there is nothing ahead of me. While in parking garages, turning on divided highways and worst of all while crossing railroad tracks. Dealership just brushed off my concerns because it wouldn't do it for them, and I don't think they checked my car at all. I also get a collision system malfunction warning, sometimes while driving and other times while sitting still. This is DANGEROUS, one day I will either be rear ended or God forbid hit by a train.
