The more I think about it I don't think its a DBW problem its a part design problem. I am not seeing it with Camaro's or Corvettes only trucks and SUVs. We had two more in today. GM now has over 11,000 on back order and are telling us they can't even promise we will have parts in Feb. The best part since the Super Bowl and ice storm last week you can't get a rent car at all today. My enterprise office is 20 cars back logged. It was such a fun conversation telling a lady I have no idea when here 19K mile 09 Tahoe will be fixed and and can't even get her a car to drive in the mean time for the next day or two.
