Example complaints
Brakes: “If the brakes are pumped 2-3 times the peddle will become really firm and hard to press. When this occurs the truck will not stop. You have to stand on the brake pedal with both feet to get the truck to stop. Pretty unnerving for a 75k mike truck still under drivetrain warranty but not covered. I use this truck for work and hauling my kids. I don't like having my kids in this vehicle!”

Took the vehicle in for servicing on october 31, 2017 and they stated to contact Gmc cares that they were familiar with this kind of problem.
