    The infotainment/radio system in my 2021 Nissan Sentra intermittently reboots and produces static. When this happens, the backup camera freezes or shuts off completely. This has occurred while I was actively reversing, causing a sudden loss of rear visibility. The screen either goes black or restarts, making the backup camera unavailable. This is a safety concern because the backup camera is required for safe reversing, and the failure happens without warning. The issue…

    The passenger front, and both back windows no longer function. This appears to be a common issue when searching the internet. There is also an issue with the keyless start, as it often does not recognize that the fob is in the vehicle, or gives a low batter warning (with a new battery). As there was already a recall on the sensor for the blind spot warnings and such, there appears to be wide spread electrical and sensor issues with this year/make/model. The windows pose a…

    I got in the car to start it and it would not start. This happened at the car wash one morning. It didn’t give me any warnings of a bad battery and the only way I started it was to have someone jump it. This has happened 4 times now. It takes several minutes for the battery to charge to start the car. I have been stranded 2 times and could not get to work on time 2 times.

    purchased my 2021 Nissan Sentra brand new with no prior owner. Around 2023, the air conditioning system stopped working. The AC will not turn on at all the switch or control that activates the system is completely unresponsive. I brought the vehicle to a Nissan dealership, where I was quoted $300 just for a diagnostic test, with no warranty coverage or acknowledgment of a known issue. This failure appears to be linked to a potential electrical fault or defective AC…

    Since having my Nissan 2021 Sentra I have for one, had to replace the battery in it twice. On a more serious note, it is now stopping the car at random and unnecessary times stating an object is in front of me. It happens once a while ago and I did not have any other signs, and it was just for a second, so I tried not to stress about it. Now it is happening more often and just this morning happened three times. Causing my car to come to a complete stop, it is very dangerous…

    I and many others have noticed that the 2020+ Nissan Sentra has a very common issue with its window switch where the driver side window works, but all passenger windows get stuck refusing to roll up or down, or do so very slowly. I have had people try to come up to my window where I could not properly shut it, I have had to leave my window partially open over night, and in the rain.

    The rear door locks on my vehicle fail to lock and unlock properly, especially using the power lock switches or key fob. This is not an occasional issue — it happens every single day. This is a major safety concern because the back doors often cannot be opened at all, which puts my children at risk of being trapped inside during an emergency or accident. In addition, the rear windows frequently get stuck and will not roll down. This is also a daily occurrence. It makes the…

    The door lock actuators in my 2021 Nissan Sentra have malfunctioned, causing my doors to unexpectedly lock or unlock. Three of the four doors are affected, including the front driver's side door and both back doors. This is a serious safety concern that can potentially lock me inside the car. This can make it difficult to leave the vehicle during an emergency. It has also put my vehicle at risk for theft. No warning lights or messages have occurred indicating there is a…
