What owners say
I changed the Air Mass Flow sensor and it’s still showing the check engine light on my dash board and giving me the same code after replacing it brand new. My brakes sound horrible after replacing both sets of brakes, front and back. The Foward Collision Warning sensor did not respond in a timely matter, resulting in a minor fender bender.
Dashboard indicates issue with forward collision warning or AEB. Car does not brake when cars in front of me brake. Took back to dealership and was told they needed to reprogram and configure sonar unit. And cost would be $437. This car was purchased in JULY
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.
The contact owns a 2020 Nissan Altima. The contact stated while driving approximately 50 MPH, the vehicle lost motive power. The contact stated that the message "Engine Malfunction" was displayed, and the check engine, traction control, and Forward Collision Avoidance warning lights were illuminated. The vehicle was taken to an independent mechanic where it was diagnosed and determined that the mass air flow sensor needed to be replaced. The vehicle was repaired but the failure reoccurred days later. The vehicle was then taken to an independent machinic where it was diagnosed and determined that the battery needed to be replaced. The vehicle was repaired but the failure persisted. The contact stated that the battery was replaced three additional times by several independent mechanics; however, the failure reoccurred. The manufacturer was not notified of the failure. The failure mileage was approximately 60,000.
The contact owns a 2020 Nissan Altima. The contact stated that while driving approximately 30 MPH, the collision avoidance system failed to activate, and the vehicle crashed into the rear of a second vehicle. During the crash, the front end of the vehicle was severely damaged, but no air bags deployed. No injuries were reported. A police report was taken at the scene. The vehicle was driven to the home and later to the body shop. The cause of the failure was not determined. The manufacturer and local dealer have not yet contacted. The VIN was not available. The failure mileage was 67,000.
The forward collision warning sensor,the rear collision sensor and the traction lights turns on and off from time to time . The transmission seems like its been force to accelerate
The dashboard camera screen on all 2024 Altima models displays a white foggy haze, which worsens at night and obstructs and distorts image view. The issue worsens in low light (garages, nighttime) where it is difficult to recognize or identify objects. On 7/10/2024, a Nissan dealership master mechanic reported to us that all 2024 Nissan Altimas suffer from this issue; however, when asked, Nissan corporate has no remedy, repair, or replacement for the component(s), causing this white fog haze that obscures the driver's view. We were told by the dealership where we purchased the vehicle that this issue only affects the 2024 Nissan Altimas. Especially at nighttime, the white foggy haze reduces our ability to identify people and objects, posing a safety concern. There have been two incidents at night where the Cross Traffic Warning and Parking Collision Warning were activated, but the driver could not identify the warning when viewing the camera screen due to poor clarity. Our family has a different 2024 model Nissan and it does not have this camera screen obstruction issue.
Adaptive Cruise control and Forward Collision warning has failed. The cruise control will not engage. The Electronic braking system has malfunctioned and this has somehow disabled the cruise control on the vehicle. The car will still brake. I understand that this has been known issue with Nissan but they are not willing to repair it.
Multiple times the car will brake while triggering the forward collision warning, sending the car into a limp mode of 40mph. This occurs at a stop sign/light, or while passing a car. I had the part replaced and the problem continues.
