What 977 owners told NHTSA about the 2015 GMC Yukon Denali Xl 1500

I was dropping my daughter off at school in the car line. I was at low speed trying to brake and with the brake all the way down couldn't stop immediately. I was able to stop but then went to go again and when tried to stop again, couldn't and hit the car in front of me. It was making a sound while trying to brake but wouldn't engage my brakes. Luckily it didn't leave any damage and the other driver said it was OK and accepted my apology as my brakes were not working correctly.

THE BRAKES FAILED IN MY CAR CAUSING A REAR COLLISION WITH AN OBJECT IN MY DRIVEWAY. AFTER INSPECTION FROM A CERTIFIED GMC DEALERSHIP, THE BRAKE FAILURE WAS NOT CAUSED BY SERVICE NEGLECT OR AGE OF BRAKES, IT WAS DUE TO THE VACCUM PUMP FAILURE TO PROVIDE PRESSURE. THIS IS THE SECOND TIME IN TWO YEARS THIS PART HAS CAUSED MY BRAKES TO FAIL. THE DEALERSHIP REPLACED THE PART AT NO COST THOUGH THERE IS NOT FORMAL RECALL ON THIS PART. BOTH TIMES THIS PART FAILED THE CAR WAS IN MOTION. THE FIRST TIME IT WAS TOWED OUT OF A CITY TO BE REPAIRED AS IT WAS DANGERSOUS TO DRIVE AND THE SECOND TIME THE FAILURE CAUSED THE VEHICLE TO COLLIDE WITH A LARGE DUMPSTER IN MY DRIVEWAY CAUSING EXTENSIVE DAMAGE TO THE REAR PASSENGER SIDE OF THE CAR. THANKFULLY THERE WAS NOT PHYSICAL DAMAGE TO ANY PERSONS IN EITHER OF THESE TWO INCIDENTS WHICH BOTH WERE NO FAULT OF THE DRIVER OR OWNER OF THE CAR.
