| Feb 2025 | VISIBILITY | Windshield Repair Issue I have a cracked windshield that I attempted to have repaired through my insurance company. The repair company I was sent to was unable to remove the windshield, so they referred me to Nissan, as they are the manufacturer of my vehicle. However, when I went to Nissan, I was informed that they could not remove the necessary bolts to replace my windshield without breaking my windshield wiper motor. This situation poses significant safety risks. A cracked windshield compromises the structural integrity of the vehicle, reducing its ability to protect occupants in the event of an accident. | Crash: No Fire: No | Unknown |
| Feb 2025 | UNKNOWN OR OTHER | The backseat driver seatbelt does not click locked. The driver seat squeaks and moves. The driver door locks while trying to open. | Crash: No Fire: No | Unknown |
| Feb 2025 | FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING | 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. | Crash: No Fire: No | Unknown |
| Jan 2025 | ELECTRICAL SYSTEM,UNKNOWN OR OTHER | 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. | Crash: No Fire: No | Unknown |

| Sep 2024 | SERVICE BRAKES,FORWARD COLLISION AVOIDANCE | Every time I drive under an over pass my vehicle will come to a stop. Placing me in DANGER with traffic. | Crash: No Fire: No | Unknown |
| Sep 2024 | SERVICE BRAKES | I Serviced my vehicle with a Nissan Dealership, and was told brake pads were good. Within a couple of weeks there was a scratching sound like the brake warning indicator. I brought my car to a mechanic to be repaired but brake pads were confirmed to be fine. Further investigation indicates a bad brake caliper in the rear. Mechanic contacted Nissan to order a rear caliper and was told it’s a known issue with the rear calipers. With the caliper not functioning properly this is a direct safety violation and can cause my brakes to seize or not function hindering my/others ability to stop. I will have the repairs done with my mechanic and I have submitted a case file with Nissan. If Nissan is aware of the brake calipers having issues then this should be on the recall list and immediately fixed. | Crash: No Fire: No | Unknown |
| Jul 2024 | POWER TRAIN | I am writing to formally lodge a complaint regarding a recurring transmission issue with my 2021 Nissan Altima. The car has been experiencing significant power loss while driving, which I am certain is linked to a malfunctioning CVT transmission system. Despite ensuring that the transmission fluid levels are correct, the problem persists. Recently, the car lost power while I was going at least 50 mph on a busy road, which is very dangerous. Additionally, I have come across numerous complaints from other owners of the same model experiencing similar transmission issues. This history of complaints indicates a widespread problem that poses a serious safety risk and warrants a recall. Although there is an extended warranty, I don’t think it is fair for others being out of warranty when this is a very known issue with all owners. A CVT should last way longer than 70,000 miles, and some owners even report issues as early as 25,000 miles. Some mechanics even tell all their Nissan customers about the cons of the CVT, so it is very well known to not be good. Nissan basically has a deadly issue on their hands. I kindly request a thorough investigation and appropriate action to resolve this matter. Thank you for your attention to this serious issue. | Crash: No Fire: No | Unknown |
| Jun 2024 | BACK OVER PREVENTION: WARNINGS | The car rear impact warning comes on when driving this has happened at least 5 times Also the windshield washer fluid light comes on even though the reservoir is full | Crash: No Fire: No | Unknown |
| Apr 2024 | ELECTRICAL SYSTEM | 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. | Crash: No Fire: No | Unknown |
| Apr 2024 | ENGINE | This has been an ongoing issue for over 2 years where I go somewhere, park and come back out and my car won’t start. I literally have to have someone come in to give me a jump so the whole time I was thinking it was a bad battery so I went and bought a new battery. Well fast forward not even 7 months later I’m in the same position I go to the store come out and my car completely has no power so I take the car to autozone and what do you know a faulty engine and alternator. So I get on line and see I’m not the only one with this issue. My main concern is I’ve always gone to my car dealership to get oil changes and not once have they ever told me after putting my car on the machine that they found an issue with neither. And again this has been going on for quite some time. My issue is now my warranty is out and it just so happen to just have ran out after my last oil change and again this was going on then and they never mentioned it. What are they going to do about this problem. | Crash: No Fire: No | Unknown |
| Mar 2024 | BACK OVER PREVENTION | The contact owns a 2021 Nissan Altima. The contact stated that while in reverse, the back over prevention camera malfunctioned and images were displayed distorted at times or black and blue, creating a visibility hazard for the driver. The cause of the failure was not yet determined. The local dealer and manufacturer were notified of the failure, but no assistance was offered. The contact was informed that the VIN was not included in the NHTSA Campaign Number: 23V628000 (Back Over Prevention). The contact stated that the vehicle had experienced the failure listed in the recall The failure mileage was 49,000. | Crash: No Fire: No | 49,000 |
| Jan 2024 | AIR BAGS,UNKNOWN OR OTHER | On 10/26/23 at 5:00 pm I was involved in an accident I was hit on the front passenger side and none of the airbags deployed I do remember that right on impact immediately my chest started hurting I also hit my head on the driver side window now i dont know how fast i should be going or how hard do i need to be hit for the airbags to deploy but they never did. When I first purchased the vehicle back in May of 2021 I had set up my nissan connect services which i was paying $14.99 a month and in those l services I had an option that if I were to ever be in an accident that it would contact my family and during the time of the incident they were never contacted. Ive contacted nissan of the situation and all they have done was reimburseme me 1 month which I feel isn't right I've even gone down to the dealership and told them my concerns and they didn't nothing about it | Crash: Yes Fire: No Injuries: 1 Towed Medical attention | Unknown |

| Sep 2023 | STEERING,SUSPENSION | My car has a detached tie rod ball joint and is causing a loss of steering control, and increasing the risk of a crash. My children are in danger yet your site says my vin has no safety recall after I reviewed the safety recall for my vehicle and noticed a connection. I can’t afford any repairs and I shouldn’t have to risk my life over a recalled problem with my make model and year vehicle. | Crash: No Fire: No | Unknown |
| Sep 2023 | SERVICE BRAKES | When traveling in a rental from SFO to Concord CA, on the Bay Bridge at 9 am on the 26 of September 2023, just as I entered the underpass section near Treasure Island, the front sensor malfunctioned and auto braked from 47 mph to 28, generated audible, tactile, and visual alarms, even though the car in front was not decelerating (auto lights, tail lights in from of me as the car went into a dark section of road may have been misinterpreted). I was almost crashed into. Scariest experience in 37 years of driving. No over ride. | Crash: No Fire: No | Unknown |
| Sep 2023 | FORWARD COLLISION AVOIDANCE | I purchased my car from Sheehy Nissan of Waldorf on November 1, 2022. At the time of purchase the vehicle had 38,709 miles. It reportedly had one previous owner and was originally titled on 3/11/2021. From the day I purchased this vehicle I have had trouble with the automatic emergency braking system. I am experiencing sudden unintended brake activation in various situations. I have experienced the emergency braking system activating when I am driving at high speeds (60-70 mph) with nothing in front of me. I have had it automatically brake when I am in traffic maintaining safe distances and speeds. I have experienced it braking when I have been leaving a parking garage - again with nothing near or around my vehicle. When this occurs, it is when the warning lights turn off. So, it is completely random and unpredictable. The warning light turns on 100% of the time I drive the vehicle. I took my car to Sheehy Nissan of Waldorf for repair of this issue on 3/28/23, 6/13/23, and 8/3/23, but, to date, they have been unable to correct the problem. Most recently (8/25/23) I was given an estimate of an additional $1,977.43 for a 4th attempt to fix this problem. I met with the Service Manager, [XXX] , on 8/28/23 to discuss the matter. He said he would talk to the Nissan area rep and their warranty rep and get back to me. Two days later he responded that the area rep offered to cover 40% of the repair cost, making my cost $808.96 for the 4th repair attempt. As you are aware, this is a known issue with this vehicle and many other Nissan models. The NHTSA started an investigation into Nissan regarding this issue in September 2019. There have been multiple lawsuits and class action suits against Nissan for this same problem, yet they continue to sell these vehicles without fixing the problem or issuing a recall.
