2015 GMC SIERRA 1500 Complaints

WHEN PUTTING THE TRUCK INTO GEAR WITH THE FOOT FIRMLY ON THE BRAKES THE TRUCK WILL SLAM INTO GEAR CAUSING THE TRUCK TO JUMP FORWARDS OR BACKWARDS.

WHEN COMING TO A STOP THE BRAKE PEDAL GETS HARD TO DEPRESS AND THE RATE OF DECELERATION CHAGES MAKES IT HARD TO JUSGE WHEN AND WHERE THE VEHICLE WILL END UP.

WHILE IN A DRIVE THROUGH I WAS CREEPING UP AND WHEN TRYING TO COME TO A STOP MY BRAKE PEDAL WOULD NOT DEPRESS ALL THE WAY AS NORMAL AND TOOK A LONGER THAN NORMAL TIME TO STOP EVEN WITH BOTH FEET PUSHING ON THE BRAKE PEDAL. I ENDED UP ROLLING INTO THE CAR IN FRONT OF ME. I TOOK THE CAR TO THE DEALERSHIP THE NEXT DAY AND WAS TOLD THAT MY VACUUM PUMP/BRAKE BOOSTER NEEDED TO BE REPLACED.

INTERMITTENTLY LOSING POWER STEERING. STABILITY TRACK LIGHT COMES ON FOR NO APPARENT REASON, HEADLIGHTS DIM WHEN APPLYING BRAKES.

WHEN YOU STEP ON THE BRAKES IN MOTION THE BRAKE PEDAL IS HARD AND VEHICLE TAKES LONGER TO STOP.

THE BRAKES PERIODICALLY DO NOT WORK AT LOW SPEEDS. THE BRAKE PEDAL GETS HARD TO PUSH TO THE POINT YOU HAVE TO STAND ON THE BRAKES TO GET THE VEHICLE TO STOP. I HAVEN'T GOTTEN IN AN ACCIDENT YET BUT IT'S BEEN VERY CLOSE TWICE NOW WHERE I'VE ALMOST HIT A CAR IN FRONT OF ME AT A STOP SIGN.

HARD BRAKE PEDAL AT LOW SPEEDS ESPECIALLY WHILE TOWING OR TRAVELING ON INCLINES. BRAKE PEDAL BECOMES HARD TO DECOMPRESS WITHOUT WARNING AND VEHICLE IS UNABLE TO BE STOPPED.

WHEN I'M CRUISING HIGHWAY SPEEDS THE TRUCK GET A VIOLENT VIBRATION AND MAKES THE VEHICLE UNCOMFORTABLE TO DRIVE.

MY 2015 GMC SIERRA FAILED TO STOP AT LOW SPEEDS TODAY. I AVOIDED THE COLLISION BY PULLING OFF THE SIDE OF THE ROAD. THE PEDDLE WAS EXTREMELY HARD TO PUSH. I RECEIVED A NOTICE BY GMC THAT ITS THE VACCUM PUMP AND THEY WILL ONLY COVER THE WARRANTY UP TO 72K MILES. MY TRUCK HAS 72,560 MILES.

I HAVE A 2015 GMC SIERRA WITH 95,198 MILES ON IT. THE AC STARTED BLOWING HOT AIR WHEN I WAS DRIVING TO WORK. I PURCHASED AND INSTALLED AN AC REFILL KIT, WHICH ONLY LASTED A COUPLE OF HOURS. I TOOK MY TRUCK TO THE LOCAL GM DEALERSHIP TO DIAGNOSE PROBLEM. DEALERSHIP CALLED TO TELL ME THAT IT WOULD BE $800+ TO REPLACE AC CONDENSER. UPON FURTHER INVESTIGATION I DISCOVERED THAT FAULTY AC CONDENSERS, AND COMPRESSORS ARE VERY COMMON PROBLEMS IN CERTAIN GMC, CHEVY, AND CADILLAC VEHICLES. WHY ARE CONSUMERS STUCK PAYING OUT OF POCKET FOR KNOWN DEFECTS THAT ARE IN EXCESS OF $800?
