2014 GMC SIERRA 1500 Complaints

AIR CONDITIONING BEGAN NOT PRODUCING COLD AIR. IN LESS THAN A COUPLE HOURS ONLY AMBIENT AIR WAS BEING BLOWN OUT OF THE VENTS. THIS IS A KNOWN PROBLEM WITH GM VEHICLES YEARS 2014-2015. GM HAS PUT OUT A SERVICE BULLETIN TO IT'S DEALERS ON THIS PROBLEM YET REFUSES TO ASSIST IT'S CUSTOMERS. BASED ON ONLINE SEARCHES THERE ARE THOUSANDS OF GM CUSTOMERS WHO ARE HAVING THE SAME ISSUE.

A/C STOPPED COOLING LAST SPRING/SUMMER. I LIVE IN LOUISIANA SO DRIVING WITHOUT A/C WAS NOT AN OPTION, ESPECIALLY WITH CHILDREN AND ELDERLY PARENTS . I WAS TOLD THAT THIS WAS A NATIONWIDE ISSUE DUE TO A FAULTY DESIGN, BUT THAT GMC WOULD NOT PAY TO REPAIR IT. I HAD TO PAY OVER $1,000 OUT OF POCKET TO GET THIS FIXED. GMC NEEDS TO REIMBURSE EVERYONE WHO HAS HAD THIS PROBLEM.

60K MILES. SERVICE BRAKE ASSIST LIGHT CAME ON AFTER 1 HOUR DRIVE. AT LOW SPEEDS, BRAKE PEDAL IS EXTREMELY DIFFICULT TO DEPRESS (AS IF NO POWER BRAKES ON ANTIQUE VEHICLE), TRUCK DOES NOT STOP AS NEEDED. DIAGNOSTIC CHECK FROM ONSTAR DOES NOT SHOW ANY CODE.

A/C NOT WORKING. BEEN TOLD BY GM DEALER THAT TGIS PROBLEM WAS ON A RECALL BUT OUR VIN DID NOT COME UP.

TL* THE CONTACT OWNS A 2014 GMC SIERRA 1500. THE CONTACT STATED THAT THE VEHICLE WAS TAKEN TO AN INDEPENDENT BODY SHOP TO HAVE SOME DAMAGES REPAIRED. THE CONTACT WAS ADVISED THAT THE FRAME UNDERNEATH THE VEHICLE WAS RUSTED. THE DEALER (ANCHOR BUICK GMC, 1 AUTOMOTIVE BLVD, ELKTON, MD 2192) WAS CONTACTED AND STATED THAT THERE WAS A TECHNICAL SERVICE BULLETIN FOR THE FAILURE; HOWEVER, THE VEHICLE WAS NO LONGER UNDER WARRANTY DUE TO HIGH MILEAGE. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE AND INFORMED THE CONTACT THAT THE VEHICLE WAS NO LONGER UNDER WARRANTY FOR THE TECHNICAL SERVICE BULLETIN DUE TO THE HIGH MILEAGE. THE FAILURE MILEAGE WAS 85,821.

VACUUM SYSTEM ON THE BREAKS ARE LOOSING PRESSURE CAUSING THE BREAKS TO BECOME NEARLY IMPOSSIBLE TO DEPRESS. I HAVE RUN IN TO MY FENCE CAUSING MINOR DAMAGE. THIS HAPPENED WHEN I WAS AT A SNAILS PACE, COULDN'T IMAGINE IT HAPPENING AT A HIGHER SPEED GM IS AWARE OF THE FIX BUT AT MY COST OF OVER 750.00. THERE HAVE BEEN NUMEROUS COMPLAINTS TO THE DEALERSHIPS AND ON GM FORUMS. THIS PROBLEM NEEDS TO BE ADDRESSED. I'M GLAD NO ONE WALKED IN FRONT OF ME WHEN THIS HAPPENED.

THE VEHICLE'S HEADLIGHT HAVE SUCH POOR ILLUMINATION IT RENDERS THE VEHICLE UNDRIVABLE AT NIGHT. GM SAYS NOTHING WRONG, I HAVE REPLACED THE HEADLIGHT BULBS WITH 3 DIFFERENT BULBS BOTH OEM AND AFTERMARKET NOTHING IMPROVES THE ILLUMINATION WITH THE STOCK LIGHT HOUSINGS.

GM HAS A MAJOR PROBLEM WITH THE VACUM PUMP FAILING ON THE 2014 AND UP 1500 SERIES TRUCKS. GM HAS ISSUED A SERVICE BULLENTIN PIT5361 FOR THIS ISSUE. WHEN THE VACUM PUMP FAILS THE BRAKES BECOME ALMOST IMPOSSIBLE TO APPLY. AFTER RESEARCHING THE PROBLEM IT IS A VERY WELL KNOWN ISSUE THAT MANY HAVE HAD. MY GMC STARTED THIS AT ABOUT THE 49,500 MILE SPOT AND HAS CAUSED ME TO STRIKE A WALL AND ALMOST A PEDESTRIAN IN A PARKING LOT. THANKFULLY I WAS ON MY TOES AND AVOIDED HITTING THE PEDESTRIAN. IM A BIG MAN AT ABOUT 265LBS. WHEN THE BRAKES FAIL TO WORK I CANT PRESS THE PEDAL HARD ENOUGH WITH BOTH FEET TO STOP THE VEHICLE. IM CURRENTLY WAITING ON GM TO RETURN A CALL FOR ASSISTANCE IN FIXING THE PROBLEM AS THIS IS A COSTLY FIX. BRAKING IS A VITAL AND HIGH SAFETY FEATURE ON A VEHICLE. WHY THIS HASNT BEEN ADDRESSED BEFORE A FAMILY IS KILLED IS BEYOND ME. ISSUING A SERVICE BULLENTINE INSTEAD A RECALL FOR SUCH A VITAL PART A VEHICLE IS RECKLESS.

LOSS OF POWER BRAKES AT LOW SPEED ESPECIALLY IN TRAFFIC AND PARKING WITH REPEATED APPLICATION OF BRAKES, PEDAL BECOMES VERY HARD AND REQUIRES MUCH PRESSURE TO MAKE VEHICLE STOP, IN REVERSE GRINDING IS ALSO HEARD. MECHANIC SAYS BELT DRIVEN VACUUM PUMP MAY BE DEFECTIVE, OTHER COMPLAINTS AND BULLETINS ARE STATING ALL COMPONENTS MUST BE REPLACED, I WOULD THINK A $58000 TRUCK SHOULD LAST MORE THAN 64K MILES BEFORE NEEDING ALL THE MAJOR BRAKE COMPONENTS CHANGED. IF YOU DON'T HAVE VERY STRONG LEGS WHEN THIS HAPPENS YOU ARE GOING TO CRASH..SHOULD BE A RECALL

WHILE IN MOTION THE BRAKE PEDAL BECOMES HARD, WILL CONTINUE TO ROLL, AND MAKES & FEELS LIKE THE BRAKE PAD ARE GRINDING.
