Help, several times I have found my 07 GMC Duramax 1-2 feet farther down my driveway from where I parked it, rolled backwards. Once I parked, shut it off and about a minute later while finishing a conversation with my wife the truck rolled about 2” back. I called a buddy who is a GM mechanic and he said there is no way that the truck can roll in park, its either in park or it will roll away immediately, I certainly believe him.
Then the other morning I found my truck about 4 feet from where I parked it, (yes I was stone cold sober when I parked) I took it straight to the dealership and they said it checked out fine, I’m stumped. The truck only has 51000 km (32000 miles) on it. I’m not crazy and no one is playing pranks, and no its not parked on ice. I was told at the shop to use the park brake, I don’t feel like that’s a fix but I don’t want it rolling across the sidewalk again either. My driveway is a slight slope and there was no sign of the tires sliding where it stopped, thinking it’s a creeping movement like what I felt when sitting in it. Anyone heard of this let me know please.
