I had parked my car in a spot at an office building. As I was about to put the vehicle in park it lurched forward going over a standard curb across a sidewalk and then into the brick wall of the building. The air bag did not deploy. The car lurched about ten feet total before hitting the wall.

Pre-Collision Assist Not available, Hill Start assist warning messages multiple times since 12/24/22. Both errors happened after having the 10R80 Transmission worked on and recalls associated with VIN corrected from 10/06-12/22. Warning messages popped up on message center on dash at time of error. This greatly increases the risk of being in an accident and causing harm to myself or someone else. Vehicle has not been inspected. Ford was contacted 01/30/23. I was told to check for obstructions in front of camera behind rear-view mirror. No obstructions found, car is kept in pristine condition. Awaiting response from Ford for an appointment day and time to have issue corrected.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2020 Ford Mustang Gt350r verdict →
