| Jul 2026 | STEERING,SUSPENSION,SERVICE BRAKES | When I make a turn, I hear a clicking noise and also when I come to a complete stop, I can a sound that sounds like a grunting noise. I had new brakes, rotors and brand new tires put on in 2025. I think my ball joints and tie rod is defective. I have a triple AAA membership and I just renewed it in June and it said that my 2021 has two recalls. NHTSA # 23V628000 The back over prevention sensing system camera & NHTSA# 21V138000 Steering Linkage Tie Rod Assembly. | Crash: No Fire: No | Unknown |
| Jul 2026 | SERVICE BRAKES,FORWARD COLLISION AVOIDANCE | My car is supposed to have an automatic braking system/collision detection. Two cars in front of me slammed on their brakes and the car in front of me slammed on his brake, and I didn't have enough time to react. I totalled my car, but my car is supposed to have a safety feature that automatically brakes. The faulty automatic braking didn't engage as it should have. | Crash: Yes Fire: No Injuries: 1 | Unknown |
| Jul 2026 | ELECTRICAL SYSTEM | 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. | Crash: No Fire: No | Unknown |
| Jul 2026 | LATCHES/LOCKS/LINKAGES | Rear door locks both do not work other than manually locking. Reported incidents online show many others have had newer Nissan vehicles like our 2021 Nissan Altima with the same issue, some have been locked in the car and had to climb out the window and others said the door unlocked and opened while driving. This is a big concern for me as a mom who has a son driving this car, the entire reason was that the safety ratings were good on this AWD full size 2021 vehicle. We bought it certified pre-owned from the Nissan dealership 2 years ago (2024) and after 1 year, both locks stopped working unless locked manually. The actuators should now have stopped working with a car only 4 years old at the time. Now is it 5 years old, still very new, and the safety issues I've read others have had is very concerning. There was a previous recall on earlier Nissan models, and I wish Nissan would recall these newer models too since you see class action lawsuits and much concern online about the many people having this issue. | Crash: No Fire: No | Unknown |
| Jun 2026 | ELECTRICAL SYSTEM,AIR BAGS,SEAT BELTS | 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. | Crash: Yes Fire: No Injuries: 1 Towed Medical attention | Unknown |

| Apr 2026 | SERVICE BRAKES,FORWARD COLLISION AVOIDANCE | The system malfunctioning is the front sensor braking. My safety and others were put at risk with this because multiple times my car has braked me and or completely stopped me because it’s malfunctioning , it happens while I am on a busy street and someone even almost rear ended me because my car braked out of nowhere. It’s called “Phantom Braking”. No, the problem has not been confirmed by dealer became they stopped answering. I took it to the manufacture but they want to charge me too much. Yes and it first appeared Feb 2nd , a day after I bought the car. So at first it will aggressively brake me and I can tell when it’s going to start braking me because this loud scratching/grinding noise appear .. the noise sounds like it’s coming from the bottom and I can feel it vibrating my car when I relax my feet on the brakes or the floor. But as soon as that noise comes on then the car starts braking me and sometimes it will cause the engine to stall and then the car will stop driving completely while im on the middle of traffic. | Crash: No Fire: No | Unknown |

| Feb 2026 | ELECTRICAL SYSTEM,UNKNOWN OR OTHER | 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.

| Dec 2025 | ELECTRICAL SYSTEM,SERVICE BRAKES,FORWARD COLLISION AVOIDANCE | 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. | Crash: No Fire: No | Unknown |
| Dec 2025 | FORWARD COLLISION AVOIDANCE | RE: Formal Demand for Vehicle Repurchase/ Buyback due to Critical Safety Defect- 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 in my vehicle that Nissan has failed to repair since I purchased it in 2021. 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: Repair Dates 2021-2025 at Passport Nissan of Alexandria 150 S Pickett St Alexandria, VA Location Despite these visits, the problem continues. Nissan’s failure to diagnose or repair this critical break/self-braking issue over several years constitutes: •Failure to remedy a known safety defect •Breach of warranty •Violation of consumer protection laws •Negligence regarding driver and public safety A vehicle that breaks on its own, especially at highway speeds – is not safe, not reliable, and not roadworthy. Because Nissan has had more than a reasonable opportunity since 2021 to correct this defect and has failed to do so, I am demanding that Nissan: 1.Buy back the vehicle at an amount equal to the remaining loan balance. I do not want to do any upgrade trade ins. This situation has gone on for years and the vehicle is now a clear danger to me and the public and my two minor children who ride in the car with me. I am requesting immediate action and a good-faith resolution. | Crash: No Fire: No | Unknown |
| Nov 2025 | 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.

| Sep 2025 | FORWARD COLLISION AVOIDANCE | 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. | Crash: No Fire: No | Unknown |

| May 2025 | 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. | Crash: No Fire: No | Unknown |
