| Dec 2019 | SERVICE BRAKES | BRAND NEW TRUCK, AT4, 15K MILES, 5 MONTHS OLD. WAS VERY COLD TODAY OUTSIDE, WAS IN A STORE AND STARTED VEHICLE REMOTELY. CAME OUTSIDE TO A RUNNING VEHICLE, SAT IN DRIVERS SEAT AND PRESSED START BUTTON. NOTICED MULTIPLE WARNING SOUNDS/LIGHTS, DASH READ "BRAKE SYSTEM FAILURE 62MPH TOP SPEED", SERVICE TRAILER BRAKE SYSTEM", STEERING ASSIST IS REDUCED DRIVE WITH CARE" SERVICE ESC". THE ABS, CHECK ENGINE, BRAKE AND TRACTION CONTROL LIGHTS WERE ALSO ILLUMINATED. I IMMEDIATELY CALLED MY LOCAL GMC DEALER (WHO IS 5 MILES AWAY) AND READ THEM ALL THE MESSAGES AND ASKED IF THE VEHICLE WAS SAFE TO DRIVE TO THEIR LOCATION. AFTER A BRIEF HOLD, THE SERVICE TECH STATED THE VEHICLE WAS SAFE TO DRIVE OVER. I ATTEMPTED TO DRIVE THE VEHICLE OUT ONTO RT6. WHILE STILL IN THE PARKING LOT, TRAVELING APPROX 10-15MPH I WAS BARELY ABLE TO STOP THE VEHICLE. IT TOOK MY FULL POWER ON THE PEDDLE TO STOP, AND APPROXIMATE 20-30 FEET OF DISTANCE BEFORE IT STOPPED FULLY. I IMMEDIATELY CALLED THE SERVICE TECH BACK AND INFORMED HER THAT THE VEHICLE WAS NOT SAFE TO DRIVE WITH 5% OR SO BREAK CAPACITY. SHE PROVIDED THE GM NUMBER FOR ROADSIDE ASSISTANCE. THE TRUCK WAS TOWED TO THEIR SHOP A SHORT TIME AGO AND I AM AWAITING THEIR FEEDBACK. ON A SIDE NOTE, I WAITED IN THE TRUCK AS I DID NOT WANT TO SHUT IT DOWN, I WANTED THE SERVICE TECH TO SEE EXACTLY WHAT WAS ON THE SCREEN. AFTER ABOUT 30 MINS, WITH ME IN THE DRIVERS SEAT WITH THE KEYS, THE TRUCK SHUT ITSELF OFF. WHEN IT RESTARTED THE MESSAGES WERE GONE, BUT THE CHECK ENGINE LIGHT REMAINED. LUCKILY I TOOK PHOTOS AND VIDEO RECORDED THIS ISSUE PRIOR TO. THE LOSS OF BRAKES FOR ANY ISSUE SHOULD BE TREATED WITH THE UTTERMOST CARE FOR SAFETY OF THE GENERAL PUBLIC. THIS SEEMLY KNOWN ISSUE WILL (IF NOT ALREADY) RESULT IN INJURY OR DEATH IF NOT CORRECTED QUICKLY. | Crash: No Fire: No | 15,400 |

| Dec 2019 | SERVICE BRAKES | TOOK MY TRUCK FOR A RECALL AT THE GMC DEALER YESTERDAY FOR BOTH SEATBELT TENSIONER AND TO UPDATE THE BRAKE SYSTEM. AFTER THAT EARLIER TODAY AFTER A RED LIGHT I GOT A BUNCH OF WARNING LIGHTS. THE WARNING LIGHTS FOR BRAKE SYSTEM FAILURE, SERVICE ESC, TRACTION CONTROL OFF, AND SERVICE TRAILER BRAKE SYSTEM CAME ON.

"BRAKE SYSTEM FAILURE 62MPH TOP SPEED", SERVICE TRAILER BRAKE SYSTEM", STEERING ASSIST IS REDUCED DRIVE WITH CARE" SERVICE ESC" CHECK ENGINE" I TURNED THE TRICK OFF, OPENED AND CLOSED MY DOOR, THEN RESTARTED. UPON RESTART, EVERYTHING WAS GONE, NO WARNINGS. APPROXIMATELY 1.5 MILES LATER I WAS AT HIGHWAY SPEEDS (70MPH) WHEN ALL THE MESSAGES RETURNED. I ATTEMPTED TO BRAKE BUT THERE WAS NO RESPONSE, PEDAL WENT NEARLY TO THE FLOOR. I ONLY SURVIVED THE INCIDENT BY SHIFTING INTO MANUAL, DOWNSHIFTING TO ENGINE BRAKE, AND STANDING ON THE WHAT I'M GUESSING WAS 5 OR 10 PERCENT BRAKE PEDAL. LUCKILY THERE WAS AN EMPTY LANE FOR ME TO DO THIS IN. | Crash: No Fire: No | 13,950 |
| Dec 2019 | SERVICE BRAKES | RANDOM INTERMITTENT VEHICLE BRAKE FAILURE. I HAVE EXPERIENCED RANDOM BRAKE FAILURE FOR 45 MINUTES AT A TIME ON MY SIERRA. NO CODES OR WARNINGS ARE SHOWN WHEN IT HAPPENS. OCCURS WHILE DRIVING, AND RANDOM. CONDITION CREATES AN EXTREMELY HARD PEDDLE WITH EXTREMELY REDUCED BRAKING POWER. SAFE STOPPING DISTANCE IS INCREASED AT LEAST 3 FOLD. VEHICLE BRAKES WILL START WORKING AGAIN IF TRUCK IS LEFT PARKED AND IGNITION OFF AFTER 30 MINUTES. I BROUGHT THE TRUCK INTO THE SERVICING DEALER, THEY DROVE IT 30 MILES AND A WEEK LATER, GM INSTRUCTED ME TO PICK MY TRUCK BACK UP AFTER NO REPAIRS DO TO THEY COULD NOT DUPLICATE. I EXPRESSED EXTREME CONCERN ABOUT SAFETY, AND GM STANCE IS, "NO CODES NO PROBLEM". I WAS INSTRUCTED BY GM TO SIMPLY BRING IT BACK IN WHEN MY BRAKES FAIL AGAIN. 2 WEEKS LATER, MY BRAKES FAILED AGAIN, CREATING A DANGEROUS SITUATION. ONCE AGAIN, THE TRUCK CORRECTED ITSELF AFTER SITTING WITH THE IGNITION OFF FOR 30 MINUTES. I BROUGHT IT BACK TO THE DEALER, AND THEY DROVE IT AND "COULD NOT DUPLICATE CUSTOMER CONCERN" ONCE AGAIN. ONCE AGAIN I WAS INSTRUCTED TO BRING THE TRUCK BACK IN WHEN THE BRAKES FAIL DURING THEIR OPEN BUSINESS HOURS SO THAT THEY CAN SEE IT FOR THEMSELVES. THIS IS AN EXTREMELY DANGEROUS CONDITION, AND THIS TRUCK SHOULD BE OFF THE ROAD AND CONCERNING TO GM, BUT IT IS NOT. THROUGH RESEARCH, I HAVE FOUND MANY OTHER PEOPLE WITH THE SAME TRUCK YEAR AND MODEL WITH THE SAME PROBLEMS, AND GM IS NEGLIGENT TOWARDS OUR SAFETY AND THE INNOCENT PEOPLE ON THE ROAD. THIS NEW "E-BOOST" BRAKING SYSTEM NEEDS TO BE INVESTIGATED BEFORE MY FAMILY OR OTHERS ARE KILLED OR INJURED BY THIS DEFECTIVE SYSTEM. BRAKE FAILURE OCCURRED BOTH TIMES WHEN ATTEMPTING SLOWING DOWN FOR CURVES AND STOPPED TRAFFIC AT HIGHWAY SPEEDS AND PERSISTED AT ALL CONDITIONS UNTIL IT RESET ITSELF AFTER SITTING OFF FOR 30 MINUTES. | Crash: No Fire: No | 7,966 |
