“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. …”
NHTSA complaint #11444993, filed 2021-12“Got the car from kingdom Chevy on 66 and western on February 2024 used at 62.000. I took the car back twice because the screen in the car kept cutting off fading on and fading off. Secondly, the Bluetooth plug would not work. I did not have the car a month. They kept telling me that nothing was wrong with the vehicle. I took my vehicle to the dealer and was told that there were no recalls on the vehicle and that basically my car was one of the cars that got put in the bad batch. I was also told that the only recall on this car was the hood. …”
NHTSA complaint #11752550, filed 2026-07“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. …”
NHTSA complaint #11661395, filed 2025-05“I purchased this car in April 2023 and in December 2023. I had to get a new battery when I purchased a car. They told me that there was no worries or mishaps with the vehicle they said just only normal wear and tear for is a used vehicle. My car is a 2021 Nissan Altima so the car would’ve been about two years old maybe or on his way to be in two years old when I got the car according to the Carfax and the information provided to me it only had one owner previously. I’m not sure what the person did with the car but the battery was bad fast-forward to 2025. I was hit by a F150 truck. …”
NHTSA complaint #11746502, filed 2026-06“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. …”
