Example complaints

“Blind side warning not working - radar not available due to side obstruction. Several times the instrument panel has malfunction - Nissan claims car must be spotless or it won't function properly. I have never had such issues with other makes. The ebs warning lights come on most of the time when temperature drops below freezing. I thought this car provided safety, instead it does the opposite. Nissan claims when there's snow on the ground safety features won't work. Why have them then? Make a point of this before I purchase. I washed the car and it blind side detector still won't work. …”

“Parked the car for roughly 10 minutes. Came back and started car with all lights on dash illuminated. Hard to drive, hard to steer and could not tell how fast vehicle was moving as speedometer didn't work. This has happened before, had it taken to Nissan dealer. Advised that they couldn't duplicate the lights issues after it sat for 3 days before resetting itself.”

“3 out of 4 of my doors have to be locked and unlocked by hand instead of using my Nissan key button to unlock my car. 3 of the motors are bad or it's some kind of electrical issue that goggle says is common in 2019 to 2020 Nissan Altimas. I feel like I shouldn't have to pay out of pocket myself to get this fixed if it's a noted common issue on goggle.”
