2021 Nissan Sentra Electrical System Problems

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.

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 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.

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.

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.

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.

Automatic emergency brake engaged while driving when there was not a car directly in front of me. There were no obstructions on the road and cars in the lanes next to me were not merging into my lane.

The contact owns a 2021 Nissan Sentra. The contact stated that while the vehicle was parked, his aunt entered the vehicle and attempted to start the vehicle; however, the vehicle failed to respond as needed. Neither a dealer nor an independent mechanic was contacted or made aware of the failure. The vehicle was not taken to be diagnosed or repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 75,094.

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.

Only the drivers window works. The passenger and 2 rear windows won't go up or down.

While driving all lights come on dash and flash on and off and says system malfunction while doing 50mph. Suddenly car shuts off while driving with my toddler I then have to push my car off the highway without getting hit This has happen 5 times now

While driving, car brakes by itself. There were no cars in front or behind. Red light flash on dashboard and then snatched brakes by itself. 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.

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.

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***

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.

1. My brakes locked up on my and the warning light came on saying I hit something 2.the only windows that works is the drivers identified 3.my warning lights came on and it started smelling inside the car I shut the car off and the warning light went off so I thought it was OK finished driving home and became sick opened the hood and my battery had smoke pouring out of each side my sinuses were burning, my throat was on fire i was sick the rest of the night i called poison control and they told me what to do

Car emergency stops with no reason. Dangerous. Will cause accident. Needs recalled.
