Four problems related to service brakes have been reported for the 2014 GMC Sierra. The most recently reported issues are listed below.
When at slow speeds, brakes get hard and have to put a lot of pressure to stop the truck.
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!.
Vacuum pump failure was noticed when parallel parking. After hitting brake several times they stopped working. Took excessive amount of force to stop vehicle.
Braking at short distances. Vehicle continues to move after brake is depressed.
