“Vehicle was delivered to me with physical damage the one of the shocks. Part of the shock tube is crushed in, up high away from the roadway. Most likely cause is damage during vehicle transportation from factory. Two dealerships have confirmed this is the most likely and possible cause. I have brought the vehicle in at least 3 times to a dealer, and have been told that only the dealership I purchased the vehicle from can perform the warranty work for this repair. I have also called Gmc customer service number in the owners manual and made a complaint there as well. …”
