I took my car in for warranty service because the front parking sensors were always going off. The dealership told me it’s because the car was hit and all sensors had to be replaced for the low price of $1,200, we had a small mark on the passenger bumper that wiped off. After going in circles with them for ten minutes I left, filed a claim for insurance, and took the car to an auto body shop who told me there was no damage to the car. After reading here I took off the front license plate holder and voila, they work as they should. I need a license plate in my state, has anyone found a fix for this?
