   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…

   Door lock actuators have failed completely on 2 doors, and intermittently on 1 door of a 2021 Nissan Altima. They do not respond to either the key fob or door button. There are no warnings or indicators associated with this component so it is unknown when the failures first occurred, but it was first noticed in summer of 2025. The components have not been inspected but could be made available for inspection if requested. Not being able to unlock doors could present an…

   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…

   Passenger back locks stopped working first. Then driver side back locks. Now both driver and passenger front locks will not lock/unlock automatically. This is scary when not being able to get in/out of vehicle for an emergency. I have reviewed multiple complaints and it appears this is a very common Nissan problem that needs to be addressed before it becomes a bigger safety problem.

   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…

    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…

    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…
