2015 GMC SIERRA 1500 Complaints

WHEN BRAKES ARE APPLIED THE PEDAL IS HARD AND VEHICLE DOES NOT STOP. IT SEEMS TO HAPPEN WHEN GOING SLOW FOR EXAMPLE IN PARKING LOTS ETC. I HAVE READ OTHER ARTICLES WHERE PEOPLE ARE EXPERIENCING SAME THING AT HIGH SPEEDS. IT DOES NOT HAPPEN ALL THE TIME, BUT IT STARTED 7/1/2018 AND I'VE EXPERIENCED THIS FOUR TIMES NOW. TOOK TO DEALER THIS MORNING THEY REFUSED TO LOOK AT ARTICLES EXPLAINING WHAT I'VE FOUND.

TRUCK WILL NOT CHANGE GEARS AND SPUTTERING. BAD GAS MILEAGE AND NOT WANTING TO START.

WHILE IN MOTION THE BRAKE PEDAL GOES HARD AND IS DIFFICULT TO STOP. I BELIEVE THIS IS THE CAUSE OF A LOW SPEED INCIDENT I HAD EARLIER THIS YEAR. THE ISSUE OCCURRES MOSTLY AT SLOW SPEEDS IN STOP AND GO TRAFFIC. IF FEELS LIKE THE BRAKE BOOSTER FAILS AND THE PEDAL IS BOTTOMED OUT. IT HAPPENS FREQUESNTLY WHILE HAULING A TRAILER IN REVERSE. VERY DANGEROUS SITUATION.

I RECENTLY PURCHASED A GMC SIERRA 1500 FROM CARMAX FITTED WITH A SET OF CROSSCONTACT LX20'S. THE TRUCK HAD ABOUT 18,000 MILES OR FEWER WHEN I BOUGHT IT AND IT NOW HAS 31,000 MILES ON IT. THE TWO FRONT TIRES STARTED TO DISINTEGRATE AROUND 28,000 MILES AND NOW HAVE BECOME UNSAFE AND UNUSABLE. I CONTACTED YOUR CUSTOMER SUPPORT OFFICE AND WAS TOLD THAT THEY COULD NOT DO ANYTHING FOR ME AS I WAS THE SECOND OWNER AND I SHOULD CONTACT CARMAX. OF COURSE CARMAX SAYS, CALL CONTINENTAL. THE CODE ON ALL 4 OF MY TIRES IS A32A WBDE 2215. I HAVE ENCLOSED A FEW PHOTOS OF THE FRONT TIRES, THE BACK TIRES ARE SHOWING THE SAME SEPARATION FROM THE STEEL BELT, BUT NONE OF THE TREAD HAS COME OFF YET. I BELIEVE THE TURNING BACK AND FORTH OF THE FRONT TIRES HAS ACCELERATED THEIR DEMISE. I HAVE PURCHASED 4 NEW GOODYEAR TIRES BECAUSE I TRULY FEAR FOR MY FAMILIES SAFETY. I WOULD APPRECIATE YOUR TIME AND CONSIDERATION IN THIS MATTER.

WHILE DRIVING IN STOP AND GO TRAFFIC SPEEDS THERE HAVE BEEN A NUMBER OF OCCASIONS THAT THE BRAKE PEDAL GOES HARD AND THE TRUCK WILL NOT STOP. I HAVE NOTICED ON OTHER FORUMS THAT THIS SEEMS TO BE A COMMON ISSUE.

AC BLOWING WARM AIR - MAY HAVE A CONDITION WHERE THERMAL CYCLING ON THE COMBINATION TRANSMISSION FLUID/OIL AND AC CONDENSER COOLER CREATES A CRACK THAT MAY ALLOW REFRIGERANT TO ESCAPE. THIS CONDITION CONSEQUENTLY MAY DEACTIVATE THE AC SYSTEM.

TAKATA RECALL. I RECENTLY CALLED THE DEALERSHIP WHERE THEY CONFIRMED MULTIPLE CALLS ON THE AC CONDENSER LEAKING FREON. WE HAVE TWO 2015 GMC SIERRAS WITH THE SAME LEAK. A SERVICE CENTER EMPLOYEE/MECHANIC AT BOB BROCKLAND IN COLUMBIA IL VERIFIED MULTIPLE COMPLAINTS.

TL* THE CONTACT OWNS A 2015 GMC SIERRA 1500. WHILE DRIVING UNKNOWN SPEEDS, HOT AIR EMERGED FROM THE AIR CONDITIONING UNIT WHILE IT WAS ACTIVATED. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHERE IT WAS DIAGNOSED THAT THE AIR CONDITIONER CONDENSER WAS LEAKING. THE CONTACT CALLED A LOCAL DEALER (BECK AND MASTEN BUICK GMC NORTH, 11300 FARM TO MARKET 1960 RD W, HOUSTON, TX 77065, 281-469-5222) AND WAS INFORMED THAT THE VEHICLE WAS NOT INCLUDED IN A SERVICE BULLETIN. THE CONTACT WAS REFERRED TO THE MANUFACTURER. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOTIFIED AND DID NOT ASSIST. THE FAILURE MILEAGE WAS APPROXIMATELY 55,000.

WHILE AT LOW SPEED AND AT STOPS WHILE TURNING THE WHEEL THE ENTIRE DASH AND ENGINE CUT OFF AND COME BACK ON. THE STEERING ALSO LOCKS UP TO A POINT OF NOT TURNING EITHER WAY. ALL INCIDENTS HAPPENED ON A VERY SMOOTH FLAT ROAD. THIS PUT MY LIFE IN DANGER ON ONE OCCASION WHILE TURNING ON A HIGHWAY WHERE MY ENTIRE TRUCK SHUT OFF MID TURN.I HAVE VIDEO OF THIS OCCURRING ON MY PHONE IF YOU WOULD LIKE TO REACH OUT TO ME FOR THAT. I BELIEVE THIS TO BE A STABILTRAC ISSUE, ONE OF GMC'S TRACTION CONTROL BRANDING THINGS. I HAVE SEEN THIS ISSUE ALL OVER GOOGLE WHILE SEARCHING IT AND IT NEEDS TO BE RECALLED! I WOULD LIKE TO KNOW IF THIS WILL HAPPEN.

THE HEADLIGHTS ON MY 2015 GMC SERRIA 1500 SLT ARE UNSAFE. THE HEADLIGHTS DO NOT LIGHT TO THE SIDES ADEQUITELY AND THIS IS VERY APPARENT WHEN MAKING A TURN AT NIGHT. I HAVE ALSO READ ABOUT THIS SAME HEADLIGHT SAFETY CONCERN ON SEVERAL WEBSITES POSTED BY OTHER OWNERS.
