2016 GMC SIERRA 1500 Complaints

TL* THE CONTACT OWNS A 2016 GMC SIERRA 1500. THE CONTACT STATED THAT THE BRAKE PEDAL BECAME EXTREMELY DIFFICULT TO DEPRESS. THE CONTACT HAD TO AGGRESSIVELY MANEUVER THE VEHICLE TO AVOID A CRASH. OURISMAN CHEVROLET OF ROCKVILLE (807 ROCKVILLE PIKE, ROCKVILLE, MD 20852, (301) 637-6496) HAD NOT BEEN ABLE TO DIAGNOSE THE FAILURE. FITZGERALD BUICK GMC ROCKVILLE (5501 NICHOLSON LN, ROCKVILLE, MD 20852, (301) 770-3300) DIAGNOSED THAT THE BRAKE BOOSTER VACUUM WAS FAULTY AND REPLACED THE PART UNDER WARRANTY. THE VEHICLE WAS REPAIRED. THE MANUFACTURER WAS NOTIFIED. THE FAILURE MILEAGE WAS NOT AVAILABLE.

WHEN I AM GOING AT A SLOW RATE OF SPEED AT FAST FOOD DRIVE-THROUGH OR BACKING DOWN MY DRIVEWAY IN REVERSE I GO TO PRESS ON MY PANEL AND NEXT THING YOU KNOW IT IS IS HARD AS A BRICK AND THE VEHICLE KEEPS GOING I HOLD MOST DIDN'T STOP GOING DOWN MY DRIVEWAY AND HIT ONE OF MY CHILDREN I'VE TOOK IT TO THE DEALERSHIP TWICE THEY SAY YOU CAN'T TAP YOUR BRAKES YOU HAVE TO LET THE VACUUM BUILD BACK UP THAT IS NO EXCUSE FOR THE VEHICLE NOT STOPPING!!!! THIS HAPPENS DAILY AT SOME POINT SOMETHING HAS TO BE DONE SOMEONE IS GOING TO GET HURT !!!!!!!

WHEN ATTEMPTING TO STOP AT LOW SPEEDS, EXPERIENCING LITTLE TO NO BRAKE PRESSURE IN DRIVE AND REVERSE. THIS IS THE THIRD OCCURRANCE SINCE NOV 2018. SYMPTOMS INCLUDE STIFF BRAKE PEDAL AND AUDIBLE CLICK UPON RESUMING MOTION AND THUMP FELT IN BRAKE PEDAL FOLLOWED BY SIGNIFICANTLY REDUCED BRAKING ABILITY. NARROWLY AVOIDED THREE COLLISIONS ON COMMUTE TO WORK THIS MORNING IN NORMAL TRAFFIC CONDITIONS.

AT LOW SPEEDS THE VACUUM PUMP GETS WEAK AND DOES NOT PROVIDE THE NEEDED VACUUM TO THE BRAKE BOOSTER. RESULTING IN LOSS OF POWER BRAKES. WHILE PARKING I BACKED UP AND THEN PULLED FORWARD TO STRAIGHTEN UP. AS I CHANGED DIRECTION A PEDESTRIAN WALKED OUT IN FRONT OF ME AND NEARLY HIT THEM. I HAD TO STAND ON THE PEDAL WITH BOTH FEET. IF MY WIFE WOULD HAVE BEEN DRIVING THE TRUCK SHE WOULD HAVE RAN THE PEDESTRIAN OVER. THE DEALER CAN NOT REPLICATE THE PROBLEM AND THEY ARE NOT GOING TO REPLACE THE BOOSTER UNDER WARRANTY. ALTHOUGH GM DOES HAVE A TECHNICAL SERVICE BULLETIN IN PLACE ABOUT THIS EXACT ISSUE. TSB # PIT5361C. THIS IS A MAJOR SAFETY CONCERN!!!! AND GM DOES NOT CARE!
