Had this issue on my 06. Took it to the dealer and they fixed it. Problem the service manager stated was that starting in 05 or 06(cant remember for sure) that GM switched style on the connectors and to fix it they replace it with the old style.
During the rod run in pigeon forge. Black SS at a local pawn shop. Arrival blue SS in front of motel parked in the grass & a Red SS cruzing around town. Anyone?
Same deal happed with the seat belt with me in my trans am. SOB watched me pull it off to raise up and get my billfold out and it was on when i went by him. Its like anything else one or two pricks here and there give the whole lot a bad name. Good luck getting it resolved.
