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.

Hi this is in reference to my 2021 Nissan altima. The fob key entry and electrical door control doesn't work. The automator for my doors have had to be replaced. First the rear passenger and five days later the rear passenger door on drivers side and now the drivers door. As a single female this is a safety issue. If I can't access my vehicle in an emergency it turns into a life or death situation. I've researched this and many owners of like vehicle have had this complaint and reported it, but appears that Nissan has ignored it. When my repairs are done it isn't inexpensive. Please please please!!! Look into this. Please and thank you. Tempe dodge chrysler and jeep Tempe Az is where the repairs are done. Jon (833) 552-1518 service department

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 manufact...
