The contact owns a 2021 Nissan Altima. The contact stated that the rear seat belt failed to latch securely. The instrument panel illuminated, and the seat belt warning light remained displayed with a beeping sound during and after the failure. The battery was replaced twice within one year, and the vehicle needed to be jumpstarted by AAA due to an issue associated with a sensor. The contact stated that while the accelerator pedal was depressed, the RPC became extremely elevated. The contact stated that the vehicle occasionally stalled and shut off unexpectedly. There was an abnormal odor coming from the vehicle which was associated with the radiator. Additionally, Bluetooth calls were dropped, a key fob failed to be recognized by the vehicle, and the TPMS readings were incorrect. The contact also stated that the windshield wiper malfunctioned, and that the remote control needed a battery replacement at the time of purchase, and that the vehicle was pulling to one side whenever the brake pedal was depressed. The vehicle was taken to the dealer, but the dealer was unable to determine the cause of the failure. The dealer associated the failure with a sensor caused by the rain. The corporate office was contacted by phone about a buyback. The approximate failure mileage was 44,011.

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. No one could open the hood, even if I pull the latch in the car. I explained to the guy at the Nissan dealer again that the board kept cutting on and off and all he said was it was the Bluetooth. Today my car does not start without me getting a jump. Lastly, I’ve been stopped by the cops three times on my way from work at night because the lights are auto and they they do not work properly. I really do not know what to do at this point. I called last week to speak to someone and I spoke to someone named David, who was not at all trying to help me, but was trying to sell me a car😡. He informed me that since it wasa used vehicle, the warranty has already iexpired. More importantly they are no longer kingdom Chevy. It is now under new ownership, and that they do not have access to the Records. I ended up with this vehicle because the vehicle that they recently leased to me. The engine went out once I got my oil changed at Valvoline.

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 entrapment hazard in the event of a collision. The doors remaining unlocked is a safety concern as there is nothing preventing the door from potentially being opened while driving, and a security concern as the vehicle may inadvertently be left unlocked even if the lock buttons are pressed on the key fob and/or door. Numerous official and anecdotal consumer reports exist but at the time of this submittal the manufacturer has not issued any notices or recalls regarding this problem.

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. I got T-bone I had to go to the hospital, etc. it was a pretty bad hit. My windows were cracked or excuse me broken and my airbags were not deployed. No airbag was deployed. I did have my seatbelt on when the police came. My CB was still on so my car had to go. It was towed, and then it went to a mechanic shop to be fixed by the other person‘s insurance at that time, the mechanic sent me photos and explain that there was faulty, wiring and seatbelts, and he was unsure why it would be there. He said it was a immediate safety hazard, and I should address it with North Coast as soon as possible North Coast auto Mall is where I purchased the car from when I reached out to them all they told me was all you’ve had the car for about three years now we don’t know what you may have done to the Car. I still have the photos of the faulty wiring. I’m no mechanic. I explained to them that was an accident and the airbags did not deploy and when the mechanic also confirmed that’s probably why I have not heard anything from North Coast. This is an extreme safety hazard.

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.

Vehicle Breaking on Its Own While Driving I am writing to file a formal safety complaint and to demand immediate corporate intervention regarding an extremely dangerous mechanical/ADAS defect. My Nissan Altima has serious, ongoing safety issues where the vehicle will unexpectedly and aggressively apply the brakes on its own while I am driving, including on highways and regular roads. This defect happens without my input, without warning, and creates a major risk of being rear-ended, losing control of the vehicle, or causing a serious accident. This issue is Not minor. It is a life-threatening malfunction that makes the vehicle unsafe to operate. I have taken the vehicle to authorized Nissan dealerships for diagnosis and repair on multiple occasions & originally they told me it should be under warranty & when they spoke to the dealership they said it did not qualify under the warranty nor the extra insurance purchased & i'd have to come out of pocket for repairs. A vehicle that breaks on its own, especially at highway speeds – is not safe, not reliable, and not roadworthy. This situation has gone on for years and the vehicle is now a clear danger to me and the public and my three minor children who ride in the car with me. I am requesting immediate action and a good-faith resolution.

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
