Driving my 2022 L5P today, parked at one of my job sites and went in for a meeting... There was a slight decline with the front end pointing down hill. Got out and took a leak next to the truck then proceeded to walk up the hill to my meeting. I came back out and my truck was gone, or so I thought. Looking further down the hill my truck slipped out of park and crashed into two parked vehicles... No one was hurt or in the vehicles. Absolutely bananas.

Maybe you corroded the parking break cable and it broke. How often does this truck side leaking happen ?

You are not alone. GM knows this and won’t admit there is an issue. We have a handful of customers with similar reports. No one hurt yet. Couple fences, barn, and cars beat up tho. One client has it on video, gets out, doors auto lock/lights flash. 3 min later the truck pops out and rolls down the driveway.

I have not personally had an issue with park on the 10speeds, yet.

That's especially wild since anytime you park on a hill it automatically sets the parking brake...
That was the hardest thing to get used to. When I'm hooked to my 5th it'll automatically set also.

I have had the truck twice just have the parking brake release and then roll on the park pawl. Scared the crap out of me and a friend who was leaning on the front end.
