I hit a deer in the middle of February. Mild damage to the bumper - all airbags deployed. Body shop did a great job, insurance company stepped up all is well until - we can not get a headliner. After months, all GMC will tell me is that the part is being re-engineered and they will let me know when it is available. I have been without a vehicle for OVER 5 MONTHS. GMC has not even stepped up enough to offer a time line or target date for availability. Shocked and disappointed with GMC customer service!!
