Awful experience at this dealership. Had to take my Sierra 1500 in multiple times, with the last trip spanning over 1 month because service and GM engineers could not properly diagnose what was going on with my truck. After 'fixing' the issue, my transfer case blew up on the interstate. When I called Sinclair service, theattendant responded 'You are to far away from our dealership, we can't help you'. Will never buy a vehicle from this family again. I would give this rating zero stars if possible.
