The other day I had something rolling around in the back seat floor. At stop sign, with nobody behind me, I jumped out to fix that noise in the back. A couple cars were rolling up behind me so I jumped in quick and to my surprise the truck wouldn't move. Thought the trans was locked up. While under pressure of cars waiting behind me I thought of the parking brake. Kept hitting those buttons down there and low and behold it unlocked and I could move. Question---Does the Ram have a safety feature that when you get out while in park with engine on, it snaps the parking brake on? Or was this some weird thing that just happened to me? Thanks
