2017 GMC SIERRA Complaints

THE STABILITRAK SENSOR KEEPS GOING ON AND OFF. I'VE HAD THIS ISSUE WHEN I FIRST GOT THE TRUCK IN THE END OF OCTOBER IN 2017. THE DEALERSHIP COULD NOT FIX IT AT FIRST BUT FINALLY HAD TO FIX SOME WIRING. I'VE SEEN IT GO ON A FEW TIMES SINCE THEN BUT NEVER STAYED ON. AND FOR ABOUT 2-3 WEEKS IT'S BEEN COMING ON AND OFF BUT STAYING MORE ON AND NOT GOING AWAY NOW. I FEEL LIKE THIS SHOULDN'T HAPPEN TO A NEWER TRUCK

TL* THE CONTACT OWNS A 2017 GMC SIERRA. THE CONTACT STATED THAT NHTSA CAMPAIGN NUMBER: 19V088000 (FUEL SYSTEM) EXCEEDED A REASONABLE AMOUNT OF TIME FOR REPAIR. THE CONTACT RECEIVED THE RECALL NOTICE IN FEBRUARY OF 2019. SPRINGFIELD BUICK GMC (431 RIVER ST, NORTH SPRINGFIELD, VT 05150) STATED THAT THE PARTS WERE UNAVAILABLE TO PERFORM THE REPAIR. THE MANUFACTURER WAS ALSO CONTACTED AND CONFIRMED THAT THE PARTS WERE UNAVAILABLE. THE CONTACT HAD NOT EXPERIENCED A FAILURE. VIN TOOL CONFIRMS PARTS NOT AVAILABLE.

TRUCK LAGS POWER WHEN PRESSING THE GAS PEDAL AT TIMES AFTER PUTTING TRANSMISSION INTO DRIVE FROM REVERSE. TRANSMISSION SHIFTS HARD INTO AND OUT OF FIRST GEAR AND AT TIMES FEELS LIKE IT IS SKIPPING 2ND GEAR DURING A DOWNSHIFT.

WAS DRIVING MY 2017 GMC SIERRA WITH MY WIFE AND YOUNG SON. I WENT TO STOP AT A RED LIGHT AND HAD NO BRAKES. THE BRAKE WAS VERY HARD TO PUSH AND MADE A FUNNY CLICKING NOISE WHEN I SHOVED IT TO THE FLOOR. I WAS BARELY ABLE TO AVOID A COLLISION AND PULL INTO A PARKING LOT. I NOTICED THEN, THAT THE SERVICE BRAKE ASSIST LIGHT WAS ON. THE TRUCK GAVE NO PRIOR WARNING THAT ANYTHING WAS WRONG. THIS WAS A VERY SCARY SITUATION THAT COULD HAVE RESULTED IN A TERRIBLE ACCIDENT.

WHEN REVERSE IS ACTIVATED AT NIGHT, THE BACKUP CAMERA COMES ON AT FULL BRIGHTNESS AND IS NOT DIMMABLE. THE BRIGHT SCREEN PREVENTS VIEW OF THE PASSENGER SIDE MIRROR AND SIGNIFICANTLY REDUCES VISIBILITY IN THE DRIVER SIDE MIRROR WHILE REVERSING. THE SCREEN CANNOT BE DEACTIVATED AND BLINDS THE DRIVER. THIS IS AN ONGOING ISSUE.

WHILE DRIVING ON THE HIGHWAY AT 70MPH, A SERVICE BRAKE ASSISTANT WARNING CAME ON. THE BRAKES AT THAT POINT WERE EXTREMELY DIFFICULT TO USE AND THERE WAS NO WAY FOR A QUICK STOP. WAS ABLE TO GET TO A DEALERSHIP WHERE THEY HAD TO REPLACE THE MASTER CYLINDER, THE BOOSTER PUMP, VACUUM PUMP AND TUBING. COST FOR THE REPAIR WAS OVER $1,200.

THE "CHEVY SAKE". AT SPEEDS OVER 70MPH EXCESSIVE VIBRATION INSIDE THE VEHICLE. THIS IS WELL DOCUMENTED ON-LINE, PARTICULARLY VARIOUS GM FORUMS AND YOU TUBE VIDEOS. IT IS MY UNDERSTANDING THAT GM DENIES IT IS A PROBLEM, BUT THEY HAVE BEEN DOING SOME BUY BACKS AND IF YOU READ SOME OF THE DEALER BLOGS IT IS EVIDENT THAT GM KNOWS IT IS A PROBLEM.

THIS TRUCK IS A 3500 HD. I WAS PULLING A CAMPER ON A 1100 MILE TRIP. WITH 50 MILES LEFT I NOTICED THAT THE TRUCK WAS LEAKING TRANSMISSION FLUID FROM UNDER THE TRANSMISSION COOLER. UPON FURTHER INVESTIGATION I FOUND THAT THE RETURN HOSE FROM THE TRANS COOLER WAS POSITIONED SO THE IT RUBBED ON A FRAME COMPONENT WHICH CAUSED A HOLE TO RUB IN THE ALUMINUM TRANS COOLANT RETURN LINE. I NOTICED THIS WHEN THE TRUCK WAS PARKED RUNNING AT A REST AREA FOR AN HOUR BUT IT WAS OBVIOUSLY AN ONGOING ISSUE. HAD I NOT NOTICED IT WHEN I DID THIS CONDITION COULD HAVE CAUSED CATASTROPHIC FAILURE OF THE TRANSMISSION. THE DEALER SAYS THERE IS NO RECALL AND IT IS NOT UNDER WARRANTY. I CONSIDER THIS TO BE A SERIOUS DESIGN FLAW AND A MAJOR SAFETY ISSUE. I WAS ABLE TO GET TO MY DELIVERY STOP AND GET THE LINE PATCHED. IT IS AT THE DEALER FOR REPAIRS RIGHT NOW.

I ALMOST KILLED A KID TODAY PARKING FOR A BASEBALL GAME. I WAS TRAVELING SLOWLY AND PARKING WHEN MY BRAKES BECAME HARD TO PUSH AND FAILED. TRUCK WENT OVER CURB AND TOWARD KID PUTTING ON HIS CLEATS AND NOT FACING ME. I WAS ABLE TO PUSH AS HARD AS I COULD AND IT STOPPED. I BACKED UP AND BRAKES WORKED AGAIN. I HAVE 46,000 MILES ON THE TRUCK. I AM NOW AFRAID TO DRIVE IT, BUT IT SEEMS THEY ARE WORKING AGAIN. IF THIS IS COMMON, GMC NEEDS TO TAKE CARE OF THIS. SOMEONE WILL SOON BE HURT SERIOUSLY!
