Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“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.”
NHTSA complaint #11567102, filed 2024-01“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.”
NHTSA complaint #11700324, filed 2025-11“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.”
NHTSA complaint #11691124, filed 2025-10“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.”
NHTSA complaint #11703182, filed 2025-12“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***”
