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.

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.

Based on comments from various post online, it is a common issue that the doors-?? lock on altimas with no warning or reasoning just stop working. Whatever position the lock is in, is the one that the lock will stay on even if a safety feature that-??s advertised and you expect is for the Altima to automatically lock up when you begin to drive. At this point my personal Altima has not been inspected or fixed by anyone, just a day to day experience of having to check my backseat before getting in to make sure no one is in the back of my car because the doors do not lock. It-??s been since about February that the car doors locking mechanism will not engage on two of my car doors, even if you press the lock/unlock switch inside of the door, the lock/unlock button on the key fob, nor the button on the outside of the door handle.

The contact owns a 2021 Nissan Altima. The contact stated that while driving approximately 25 MPH in a rainstorm, the automatic emergency braking system warning light illuminated, however, the vehicle failed to stop. The contact continued to drive and noticed that once they cleared the rainstorm the warning light disengaged. The contact informed the dealer and was informed that the repair was not covered under warranty. The contact had not taken the vehicle to the dealer to be diagnosed or repaired. The contact stated that the failure was related to NHTSA ID Number: 10207869 (Electrical System, Forward Collision Avoidance). The manufacturer was made aware of the failure and informed the contact that the rainstorm could have caused water to enter into the sensors for the automatic emergency brake to become defective. The approximate failure mileage was 17,000.

While driving home from work I experienced my fourth or fifth malfunction error flashing across my digital display. It scares me because this time is different. This time the flash made the seat vibrate and before I had a chance to react, I totally lost control Of my steering even though I had my hand family placed on each side of the wheel none of my maneuvers resulting in the tires moving in any direction. I was trying to straighten myself out but the trajectory Steered me to the right side of the road and up over the curb which tore out my front end And, had it not been for my superb braking skills, id be headfirst into a big cement hole on the side of the road. Brakes We-??re locked out until I pressed on them 15,000 times it seems. Fortunately I am the only one hurt, I-??m grateful that no one else has been involved in this malfunction of supposed quality machinery. But this is a ridiculous thing to have happened to listen 1000 miles in the car, this thing has been malfunctioning since the first day that I drove it off the lot. No clue who to get in touch until I started researching this Very same thing, and I am terrified for anyone else driving one of these vehicles right now, because It can Totally happened to you, and you may not be so lucky to have all the injuries only for yourself.
