Gear: When going through an sutomated car wash on a conveyor belt car was put in neutral and hands were off the steering wheel as instructed. about 3/4 wasy through the car wash, even though the car was still in Neutral the car started to reverse : the rear camera did not go on and there was no warning beep about a vehicle behind us and it was bumping into the front of that higher vehicle that stopped the reverse. They had no damage but our rear tailgate to the right of the license plate had peeling paint and an outward bump. We talked to the car wash owner about a possibility of a faulty conveyor belt but he denied this and showed video evidence (due to our wheels moving) that the car was in reverse, blaming us for shifting gears, which we did not do. The estimated repair for the damage we received from a trusted auto body shop is 1089.00 due to the painting and what they say is a misalignment of the tailgate. Our dealer , McGrath Honda, stated there had been no recalls of car going in different direction of the gear it is in. Had this happened on a highway ours and others safety coulf have been at risk. Upon request vehicle component and system is available for inspection.
