2015 GMC SIERRA 1500 Complaints

THE PAINT ON MY 2015 GMC SIERRA IS BUBBLING AND PEELING. AFTER MUCH RESEARCH I FOUND THAT THIS A CONSISTENT DEFECT ON MY YEAR VEHICLE. I CONTACTED GMC AND MY DEALER THORSON GMC IN PASADENA CALIFORNIA. THE SERVICE MANAGER AT THORSON GMC DON SCHWARTZ HAD HIS BODY SHOP LOOK AT THE PAINT ON MY TRUCK AND HIS RESPONSE TO ME WAS THAT THE PAINT ON THE CHIPPING AREAS ON MY TRUCK, BOTH REAR DOORS AND THE ROOF, WAS EXTREMELY THIN AND THAT HE WOULD TRY TO GET GMC TO REPAINT MY DOORS AND ROOF AT THEIR EXPENSE. TWO WEEKS LATER MR. SCHWARTZ CALLS ME BACK AND TELLS ME THAT GMC IS ONLY WILLING TO PAY 40% OF A $5000 PAINT REPAIR AND THAT I WOULD HAVE TO PAY $3140 IF I WANTED MY CHIPS REPAIRED. I FEEL THAT THIS IS RIDICULOUS TO HAVE TO PAY FOR AN OBVIOUS FACTORY DEFECT. ADDITIONALLY I REALLY FEEL FOR THE THOUSANDS OF PEOPLE FACING THE SAME PROBLEM BECAUSE GM DIDN'T PAINT THEIR VEHICLES CORRECTLY

BRAKE VACUUM PUMP BOOSTER. FIRST STARTED WHEN DRIVING UNDER 5 MPH. THE BRAKES WERE HARD TO PUSH DOWN AND WOULD NOT STOP THE TRUCK PROPERLY. DID THIS FOR APPROXIMATELY 3 MONTHS. THEN DRIVING GETTING OFF THE INTERSTATE AND APPLIED BRAKES GOING 60 MPH THE BRAKES WOULD NOT WORK. COULD BARLEY STOP. SAME ISSUE HAS WHEN DRIVING SLOW. NOW THE BRAKES WILL NOT WORK AT ANY SPEED. THEY TRUCK IS UNDRIVABLE UNTIL IT GETS FIXED.

POWER LOCKS NOT LOCKING ALL DOORS. COULD BE A PROBLEM WITH A CAR JACKING OR CHILD PROOF LOCKS. ON MY 3 LOCK ALREADY 42000 MILES. I DON'T FEEL SAFE

AT LOW SPEED AND ON A NUMBER OF OCCASIONS, THE BRAKES HAVE SEEMED TO LOSE POWER AND IT REQUIRED A LOT OF BRAKE PRESSURE TO STOP THE VEHICLE AND AVOID HITTING ANOTHER VEHICLE, MY GARAGE, ETC. IT HAD BEEN HAPPENING INTERMITTENTLY OVER THE PAST MONTH OR SO. WENT IN TO THE DEALER AND THEY REPLACED THE VACUUM PUMP AT A COST OF APPROX $600.

VERY DIFFICULT TO STOP THE TRUCK WHILE GOING AT A LOW RATE OF SPEED 5 TO 10 MPH. HAD TO FORCEFULLY APPLY PRESSURE TO THE BRAKE PEDAL TO GET IT TO STOP STILL REQUIRED MORE STOPPING DISTANCE. BRAKES DID NOT BECOME FULLY FUNCTIONAL UNTIL AFTER PLACING THE VEHICLE IN PARK AND SHUTTING THE VEHICLE DOWN WAITING FOR APPROXIMATELY 15 MINUTES. RESTARTED THE VEHICLE AND BRAKE WERE FUNCTIONING PROPERLY. THIS EVENT OCCURED AT APPROXIMATELY 46,000 MILES ON THE VEHICLE. FOLLOWING DAY BROUGHT THE TRUCK INTO THE LOCAL GMC DEALER AND VERIFIED THAT THE TRUCK HAS A BRAKING PROBLEM FOUND A LEAKING BRAKE BOOSTER AND MASTER CYLINDER.

2015 GMC SIERRA SLE / 60K MILES / PROJECTOR HEADLIGHTS...NUMEROUS COMPLAINTS FROM NUMEROUS OTHERS, I'M IN THE SAME BOAT. ILLUMINATION IN GENERAL, DRIVING IN RURAL AREAS, DRIVING IN INCLEMENT WEATHER, MAKING TURNS (SIDE STREETS), ETC., IS HORRIBLE, UNSAFE, NERVE-RACKING AND TROUBLESOME. SURE, THE HEADLIGHTS LOOK SNAZZY, BUT PERFORM ABOUT AS WELL AS MY LAWN TRACTOR'S HEADLIGHTS. I SEE THERE'S A TSB REGARDING THE SITUATION AND, MUCH TO MY DISMAY, I HAVE TO PAY FOR SAID PARTS/LABOR TO CORRECT AN OBVIOUS DESIGN FLAW/SNAFU. AM I CRAZY FOR THINKING THIS IS UNACCEPTABLE? EVEN MORE SHOCKING, IT APPEARS THE BCM REPROGRAMMING (MARGINAL RESULTS) AND LAMP REPLACEMENT IS PROBLEMATIC (INCREASED VOLTAGE TO A BULB/LAMP SHORTENS ITS LIFE CONSIDERABLY). A VEHICLE THAT COSTS 30-40-50K SHOULD NOT HAVE GARBAGE TECHNOLOGY. ON THE PLUS SIDE, AT 48 YEARS YOUNG, MY VISION REMAINS 20/20 AND I DO NOT REQUIRE VISION CORRECTION. THE WIFE, MY 2 KIDS (OF DRIVING AGE) AND MY NEIGHBOR CONCUR - THESE HEADLIGHTS SUCK. I LOVE EVERYTHING ELSE ABOUT THE VEHICLE, BUT IT LOOKS LIKE INSTEAD OF SPENDING $200 FOR THE TSB, I'LL TRY MY LUCK WITH AFTERMARKET REPLACEMENTS FOR $300. VIA MULTIPLE ONLINE VEHICLE FORUMS, MOST WHO'VE GONE THE ROUTE OF TSB ARE MARGINALLY IMPRESSED AND EVERYONE ELECTING TO GO WITH AFTERMARKET IS COMPLETELY SATISFIED...THAT ALONE SHINES A SPOTLIGHT ON THE LACK OF VISIBILITY BOTH THE NHTSA AND GM ARE PROVIDING THE CONSUMER. MAYBE INSTEAD OF PAYING SUITS MILLIONS PER YEAR TO PRODUCE SUBPAR VEHICLES, GM SHOULD DO THE RIGHT THING AND FOCUS ON WHAT MATTERS MOST -- THE PAYING CUSTOMER. YEAH, WE HAVE A BETTER SHOT WITH THE NHTSA HOLDING GM ACCOUNTABLE AND FORCE THEM INTO A RECALL (CORRECTING THE PROBLEM PROPERLY, NOT A WILLY NILLY REPROGRAM AND BULB REPLACEMENT).

THE BULBS IN THE TAIL LIGHTS CORRODE IN PLACE DUE TO EXCESS ROAD GRIME (SALT, SAND, ETC.) BEING SPLASHED UP ON THEM. THIS CAUSES THEM TO BURN OUT PREMATURELY AND REMOVAL IS IMPOSSIBLE DUE TO THE CORROSION OF THE BULB INTO THE SOCKET. THIS RESULTS IN HAVING TO REPLACE THE ENTIRE WIRING HARNESS. ACCORDING TO MY LOCAL GMC DEALERSHIP (WEST HERR), THIS IS A COMMON PROBLEM THAT GM ISN'T COVERING. SO, I HAD TO PAY FOR A NEW WIRING HARNESS OUT OF POCKET IN ORDER TO REPLACE ONE OF THE TAIL LIGHT BULBS.

VACUUM PUMP FAILED AT 58000 MILES. LOST BRAKE ASSIST AT PARKING LOT SPEEDS. COULD HAVE CAUSED AN ACCIDENT.

THE BRAKES AT A LOW RATE OF SPEED (1-10 MPH) PARTIALLY GIVES OUT WHICH PROLONGS THE STOPPING DISTANCE OF THE VEHICLE. IT SEEMS AS THOUGH THE ABS KICKS IN BUT FOR NO REASON. MUST STRONGLY PUSH DOWN ON THE PEDAL TO GET VEHICLE TO STOP, WHICH STILL REQUIRES ADDITIONAL STOPPING DISTANCE. HAS OCCURRED SPORADICALLY FROM MID-2018 TO MARCH 2019. NO RESOLUTION THROUGH DEALERSHIP.

BRAKES COMPLETELY FAILED. REPLACED BRAKES ON ALL 4 WHEELS, BUT TO NO AVAIL. THEN REPLACED THE MASTER CYLINDER AND STILL NO BRAKES. MY FENCE POLE AND MAILBOX STOPPED MY VEHICLE.
