Thanks for the reply bbf.
I really never park on an incline. It rolls on flat surfaces all the time.
I have not used the parking break, but will try in the future annd see what happens.
This vehicle has been a huge disappointment - nothing but problems.
Had to bring it in because the gas cover wouldn't seal, the heat doesn't work, the screen goes black, the backup camera doesn't always work and the clock keeps showing the wrong time. Also - it has a lot of wind noice when driving. I have less than 2,000 miles on it. It is my first Ford, but it looks like it may be my last.
