ELECTRICAL SYSTEM
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

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
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.

ELECTRICAL SYSTEM
About a month ago I noticed my backup camera had gotten dark. I didn’t worry much about it until it started glitching a couple days ago. I gave it a couple of days thinking it would go away but it hasn’t. It either glitches with lines through it, it freezes, or goes black altogether. I then did some research on it finding that there have been recalls on the 2021 nissan altima model cameras, just not mine specifically. I’m not sure why that is but it’s an issue I’m not willing to pay out of my pocket knowing that it’s been a year to model issue in the past. I would like this recall to be put in place and me be able to get it repaired free of charge seeing that it’s an obvious danger while backing up and the fact I did not personally damage it.

VISIBILITY:WINDSHIELD WIPER/WASHER
Windshield Repair Issue I have a cracked windshield that I attempted to have repaired through my insurance company. The repair company I was sent to was unable to remove the windshield, so they referred me to Nissan, as they are the manufacturer of my vehicle. However, when I went to Nissan, I was informed that they could not remove the necessary bolts to replace my windshield without breaking my windshield wiper motor. This situation poses significant safety risks. A cracked windshield compromises the structural integrity of the vehicle, reducing its ability to protect occupants in the event of an accident.

ELECTRICAL SYSTEM, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, UNKNOWN OR OTHER
Purchased the car in June of 2024 with around 33,000 miles. I thought the doors were locked and someone was able to just open my back door when my car was unattended in a store parking lot; the car was supposed to be locked. Lights and horn started going off. Being a female with a child this is a very scary issue. The idea that anyone can get in when you think the doors are locked or vice versa, in the event of an emergency no one can get in because the doors dont unlock. It started with the passenger side rear door lock not working with fob or button. The lock needs to be done manually. The dealership looked at it and said they could not replicate the problem and everything was working. Now both rear door locks dont work with the buttons or the key fob. The rear doors have to be locked and unlocked manually all the time. Car is currently at the dealership and they confirmed the issue and are telling me that the BCM (i believe is what they said) needs to be replaced and reprogrammed. The car only has approx. 42,500 miles. The other issue with the car is the automatic emergency braking system light comes on and flashes on the dash. It is very random and sometimes it doesnt do it at all. There can be nothing in front of me on the road when it starts flashing. It also does it in all weather conditions, and even when its dry. There have been multiple issues with this car since the day I purchased it.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER
I was driving with my child in the car and the volume on the radio spiked to an extremely high level. This has happened multiple times and the volume control knob is defective so I cannot turn down the volume or the radio off. I brought the vehicle into the Nissan dealer and they diagnosed an internal failure to the A/V control unit and recommended replacing this. When the volume spikes to full blast, I cannot turn the radio off. They are charging $2000 to have this repaired even though it's a safety hazard and I am distracted while driving to keep trying to turn the volume off or the radio off. The controls do not work and they independently turn the volume on full blast.
