Nissan North America, Inc. (Nissan) is recalling certain 2019-2021 Altima and 2020-2021 Sentra vehicles. Damage to the camera harness can cause distortion or loss of the rearview camera display image. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 111, "Rear Visibility."
A rearview camera that does not properly display an image can reduce the driver's rear view, increasing the risk of a crash.
Dealers will inspect the rearview camera and harness for damage and replace them as necessary. If no damage is found, the dealer will apply protective tape and reroute the rearview camera harness. Repairs will be performed free of charge. Owner notification letters are expected to be mailed October 19, 2023. Owners may contact Nissan's customer service at 1-800-867-7669. Nissan's number for this recall is R23C3.

Electrical system, Apr 27, 2026
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 occurs repeatedly and is not driver-related. The problem appears to be related to the head unit malfunctioning, which disables the backup camera system.

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 safety risk if someone is trapped in a vehicle that the doors won't open.

Purchased brand new with 0 miles. The system malfunction popped up and engine would not turn over after running perfectly fine a hour prior.Had to get towed to dealership and found a faulty battery luckily I still had 100 or so miles left on my warranty.Happened again last month the same exact thing except this time I had to get a jump off after several minutes the engine finally turned over.

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 component. It compromises both comfort and safety, especially in extreme temperatures. Numerous complaints online suggest this is a recurring issue among Sentra owners, yet Nissan has not issued a recall for the AC system. I am submitting this report to request an investigation into a possible manufacturing defect and to advocate for a formal recall.

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 and I am not sure what I am to do about it.

Passenger side power windows and driver side rear window on occasion will stop working.
Electrical system, Oct 3, 2025
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 problem even more dangerous because the windows cannot be used as an emergency exit if the doors fail. These issues are consistent and ongoing. Because the vehicle is used to transport children, the defective door locks and windows create a significant safety hazard that could prevent occupants from exiting the car quickly in an accident, fire, or similar emergency.

Rear windows and passenger window are malfunctioning. They stay open and will not close. Takes many attempts, and push start car on and off attempts. Takes hours for them to work again. Currently not using rear windows. To be on the safe side.

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 problem. There are no recalls for my vehicle due to this problem. I took my car into the local Nissan dealership in Kansas City, and they gave me a price quote of $884.05 to fix the problem.

All power windows stop working except drivers window. None of the window buttons on any of the doors will work when it's cold outside. They start working again in warm weather. Seems like window lock is getting stuck. Sometimes pressing it repeatedly will cause the windows to start working but will stop working again.

Another time, someone came close behind me and my car stopped by itself again nearly causing the driver to run into the back of me. Sensor light come on. Doesn't recognize my key. It's been reset but same problem.

When the sun is out and there is no clouds obscuring the sunlight my vehicle has night time lights running, dimming the interior of my car making it difficult to see the speed and other dashboard requirements while perfectly bright and sunny outside and 0800AM as well as 1500PM. This has been going on for two months and I took it in to two dealerships. One told me check your manual and the other went further and told me "by Nissan standards it is functioning normally." This doesn't make sense to me as the sun is out, it isn't dark or dim and yet when on automatic lighting my Night lights, not my normal running lights,,are on and causing me unable to see what's on my dash. Also whe. The sun is hitting the front of my car my Nissas blinks the collision indicator showing it won't do it as something is obstructing it but this happens when the sun is directly pointing in certain areas of the sky. More so early morning and late evening just as the sun is rising and falling.

The passenger window and back windows will not roll up or down. The only window that works is the drivers window. This car was bought 2 months ago and stopped working last week.

I was traveling at about 40mph when my vehicle, with no traffic in sight, had the automatic emergency brake go off and reduced my speed to 32mph. My safety concern is what if this happens on the freeway or even while raining. if there was a car behind me what if it caused them to get road rage. ***dashcam video available***

The only window that is working properly in my car is the driver window. The other 3 sometimes work and sometimes will not roll down at all. On occasion it goes down but does not come back up or doesn't go back up but half way then stops. I have taken to the dealership twice and still it has not been fixed. Cannot really use the windows at this point as I may not be able to get them back up so definitely cannot leave car unattended in any parking lot or down in certain weather situations.
