   The truck rapidly accelerated while I was slowly rolling into a parking spot with my foot on the brake. The harder I pushed the brake the more it seemed to accelerate. I luckily avoided hitting anything. I forced the gear shifter out of Drive into park. No warning lights or messages. I contacted 3 Ford dealerships and all said they haven’t heard of this nor do they think they could identify this problem if I brought it in.

Not even a loaner.
