Example complaints

Air bags: “Takata recall for passenger side air bag inflator issued july 2015. I have contacted dealership and Gmc repeatedly since receiving this recall and as of today they have no idea when parts will be available. Their suggestion was to not let anyone ride in the front passenger seat. I want something else to drive until issue resolved.”

NHTSA complaint #10882071, filed 2016-07, 50,000 miles

Fuel system: “While driving in a one lane construction zone with no place to pull over, the vehicle lost power and would not go over 10 MPH, requiring it to be towed to the nearest dealership. This durmax diesel engine had only 84,000 miles and had excellent service maintance. Cost to repair is 3860.00.”

NHTSA complaint #10760769, filed 2015-09, 84,000 miles

Tires: “My 2008 Gmc sierra 3500hd has a chatter when turning, GM is aware of the problem and has a bulletin for a repair, however the repair may or may not completely solve the issue it didn't on mine. While turning the rear axles stays in a lock position and doesn't allow the rear tires to turn separate speeds this can cause the vehicle to go into a skid without notice and they set front and rear tire pressures different and the door stickers confirm that this is like driving a 4 wheel drive with small tires on the front and big tires on the back. …”
