POWER TRAIN
I HAVE HAD ISSUES WITH MY GMC SIERRA SINCE IT WAS NEW. IT HAS JERKED AND CLUNKED WHEN I START TO GO AND THEN LEFT OFF THE GAS. THERE HAS ALSO BEEN A HESITATION WHEN STEPPING ON THE GUESS. I HAVE TAKEN IT TO THE DEALER SEVERAL TIMES AND WAS TOLD THINGS SUCH AS: "I JUST NEEDED TO GET USE TO THE 8 SPEED TRANSMISSION"," THE HESITATION IS WHEN THE TRUCK SWITCHES FROM V4 TO V8". AND "THERE IS NOTHING WRONG". NOW THE WARRANTY HAS EXPIRED AND IT IS GETTING WORSE. IT NOW FEELS LIKE "RUNNING OVER A RUMBLE STRIP" OR LIKE IT IS "MISSING" AND "HESITATING". ALL OF THESE THINGS OCCUR WHEN THE VEHICLE IS IN MOTION.

SERVICE BRAKES
BREAKS DO NOT WORK AT LOW SPEED IN REVERSE, BREAK PEDAL GOES ALL THE WAY TO THE FLOOR AND EXCESSIVE PRESSURE MUST BE APPLIED IN ORDER TO STOP VEHICLE, THIS IS EXTREMELY UNSAFE DUE TO LOW VISIBILITY WHEN BACKING THE VEHICLE.

SERVICE BRAKES
I WAS ON MY WAY BACK FROM A BEACH VACATION SATURDAY, JUNE 29, 2019 ALONG WITH TWO OTHER VEHICLES DRIVEN BY OTHER FAMILY MEMBERS. I DRIVE A 2016 SIERRA 1500 SLT WITH 30,000 MILES ON IT. AFTER DRIVING FOR 1 1/2 HOURS WITH MANY OPPORTUNITIES TO USE MY BRAKES, OUR CONVOY NEEDED TO MAKE A STOP TO TURN LEFT. TO MY GREAT SURPRISE THE POWER ASSIST WAS NOT WORKING. AT FIRST I THOUGHT I HAD NO BRAKES AT ALL. I PRESSED HARD WITH BOTH FEET AND STOPPED THE TRUCK BEFORE I REAR ENDED MY SON IN LAW AND HIS FAMILY. SCARED ME TO DEATH!! I PHONED AHEAD TO OUR LEAD CAR AND TOLD THEM I HAD SERIOUS VEHICLE PROBLEMS. THERE'S NO WAY I COULD DRIVE 400 MILES WITH HEAVY TRAFFIC SAFELY. WE SEARCHED FOR THE NEAREST GM DEALER AND SELECTED J. M.JACKSON IN ANDALUSIA, AL. EVEN THOUGH IT WAS A SATURDAY, THE SALES PEOPLE CALLED THE SERVICE MANAGER WHO CAME IN ALONG WITH A SERVICE TECH. SHORTY I HAD A NEW VACUUM PUMP INSTALLED AND THERE WAS NO CHARGE SINCE GM HAD ISSUED A SERVICE BULLETIN. BUT NOW I'M WORRIED ABOUT ANOTHER FAILURE. I BARELY AVOIDED AN ACCIDENT THIS TIME. THERE WAS ABSOLUTELY NO WARNING PRIOR TO FAILURE . AFTER THE INITIAL FAILURE TO BRAKE PROPERLY, I GOT A SERVICE BRAKE ASSIST MESSAGE. VERY DANGEROUS FAILURE. A CRASH WAS NARROWLY AVERTED.

SERVICE BRAKES
JUNE 27TH I WAS LEAVING A GAS STATION IN NOVATO CA WITH MY DAUGHTER AND FATHER IN THE TRUCK. I SLOWLY STARTED MOVING THROUGH THE STATION AND NOTICED MY BRAKES WERE ALMOST COMPLETELY GONE. FORTUNATELY I WAS CLOSE TO HOME SO I DROPPED DOWN TO FIRST GEAR AND SLOWLY MOTORED HOME TO WAIT FOR THE TOW TRUCK. I HAD THE TRUCK TOWED TO THE NOVATO CHEVY DEALERSHIP AND THEY COULD FIND NOTHING WRONG WITH THE TRUCK. I THEN BEGAN THE PROCESS OF REQUESTING GM TO BUY THIS TRUCK BACK AND ITS DEFINITELY NOT GOING TO BE A SHORT PROCESS. IM STILL CURRENTLY DRIVING THIS THING WITH NO DIAGNOSIS OF ANY BRAKE ISSUE. MY WIFE WON'T EVEN GET INTO THE TRUCK. I ABSOLUTELY LOVE THIS TRUCK AND WISH THERE WAS A DEFINITIVE ANSWER TO WHAT HAPPENED. GM CORPORATE SAID IF IT HAPPENS AGAIN TO PLEASE BRING IT INTO THE DEALERSHIP FOR EVAL. IF IT HAPPENS AGAIN?!!! IM NOT COMPLAINING ABOUT THE AIR COOLED SEATS NOT WORKING PROPERLY! I DRIVE A FIRE ENGINE FOR A LIVING AND MY JOB IS TO KEEP OTHERS SAFE. NOW I'M HAVING TO DRIVE THIS THING WHILE WAITING FOR GM TO STEP UP AND BUY THIS BACK BEFORE THE BRAKES GO OUT AGAIN. I SUPPOSE SOMEONE WILL HAVE TO DIE BEFORE GM ACKNOWLEDGES THERE'S AN ISSUE HERE.

SERVICE BRAKES
BRAKES DO NOT WORK WHEN IN REVERSE OR AT LOW SPEEDS. PROBLEM WAS THERE THE DAY I PURCHASED THE VEHICLE. A COUPLE WEEKS AFTER PURCHASE I BACKED INTO VEHICLE IN A PARKING LOT. I WAS TOLD IT WAS "NORMAL" AFTER ALMOST HAVING A WRECK I DID SOME RESEARCH. HOW IS THIS NOT NATIONALLY ADVERTISED AS A RECALL YET? THIS IS A HUGE SAFETY NEGLIGENCE ON GMC'S PART. THE VACUUM PUMP IS KNOWN TO FAIL BY EVERY DEALER I HAVE CALLED. ALSO EVERYONE I KNOW WHO HAS THE SAME MODEL TRUCK ALSO LIVES WITH THIS PROBLEM.

SERVICE BRAKES
WHEN THE TRUCK'S VACUUM PUMP FAILS, THE BRAKE PEDAL BECOMES VERY HARD TO PUSH. THE TRUCK DOES NOT STOP AT LOW SPEED WHEN THIS HAPPENS. THE FIRST TIME THIS HAPPENED, I WAS BACKING INTO A PARKING SPACE AT CHRISTMAS TREE STAND. I NEARLY BACKED INTO THE TENT AND PERSONS LOADING THE CHRISTMAS TREE IN THE TRUCK. THE SECOND TIME THIS HAPPENED, I WAS PARKING MY TRUCK IN DRIVEWAY. I ROLLED ABOUT 6' TO 8' BEFORE STOPPING. I NEARLY HIT MY HOUSE. GM ISSUES A "SPECIAL WARRANTY" BUT THEY REFUSE TO COVER THE REPAIRS BECAUSE OF THE VEHICLE MILEAGE. THIS SAME ISSUE IS WELL DOCUMENTED BY OTHER GM TRUCK OWNERS FOR 2014 TO 2018 MODEL YEARS.

SERVICE BRAKES, ENGINE, STEERING
I ONLY HAVE 57,000 MILES ON MY TRUCK, WHICH IS WHY I AM REPORTING THIS. THE TRUCK TURNS OFF COMPLETELY. I HAVE BEEN GOING TO MAKE A RIGHT/LEFT TURN AND THE TRUCK SHUTS DOWN COMPLETELY. I HAVE NO POWER STEERING AND LIMITED BRAKES. THIS HAS HAPPENED TO ME TWICE NOW. I AM LUCKY ENOUGH THAT I AM STRONG ENOUGH TO TURN THE TRUCK WITHOUT POWER STEERING OTHERWISE I WOULD HAVE HIT VEHICLES BOTH TIMES THIS HAPPENED. THERE HAS TO BE SOME TYPE OF ELECTRICAL FLAW THAT IS MAKING THIS HAPPEN. I WANT TO GET THIS RESOLVED BEFORE MY INSURANCE COMPANY HAS TO GET INVOLVED BECAUSE I AM IN A CAR ACCIDENT. IF THIS IS SOMETHING THE MANUFACTURER TAKES CARE OF THAT WOULD BE GREAT, OTHERWISE I WOULD JUST LIKE TO KNOW IF SOMEONE ELSE HAS HAD THIS ISSUE AND HAS FOUND THE RESOLUTION.
