I enter a road from a business driveway where you have to stop, it's a blind spot. It's steep enough that many rear drives can't use it in the winter. It's just weird, as I'm pretty sure it didn't roll back the first times I stopped there. Now, it's like I'm in neutral.Maybe you need a bigger hill? or have you tried to activate it? I read that if you repeat these steps you can turn it back on if you decide you want it again.
