2015 GMC Sierra 1500 Driver assistance Problems

the steering assist fails, Power and steering is reduced at driving speeds. Steering wheel locks and vehicle looses voltage and stalls while driving at low speeds and have been close to collision. Vehicle was inspected by Group One Gmc in el Paso Texas. They did not fix recall because it "did not pertain to my vin" . There is a recall for the steering assist on all gmc 2015 1500, but not for my gmc 2015 1500 for some reason. Whether it was manufactured in the us or the moon its still a gmc 2015 1500 with faulty steering assist system from the manufacturer with an open recall. Thanks for your help

I am reporting a critical issue with the transmission. The transmission frequently slips, hesitates, and jerks unexpectedly during acceleration and gear shifts. On multiple occasions, the vehicle has lost power or failed to respond while entering intersections, merging onto highways, or attempting to accelerate—posing a serious safety risk. The issue often occurs without warning and has worsened over time. Additionally, there are instances of harsh downshifting, delayed engagement from park to drive, and sudden lurching forward or backward, which could easily result in a collision. Despite visits to the dealership and complaints made, the issue has not been resolved, and I’ve learned that many other owners of this same model have reported nearly identical symptoms. This appears to be a systemic problem with the transmission system. Given the safety risk, especially in traffic and at high speeds, I strongly believe this defect warrants immediate investigation and a formal recall.

The contact owns a 2015 GMC Sierra 1500. The contact stated while driving 75 MPH, the accelerator pedal was depressed; however, the vehicle failed to accelerate as intended. Additionally, the contact stated that there was an abnormal squeaking sound coming from the vehicle. The vehicle was driven to the shoulder of the roadway. The contact stated that the failure reoccurred while hauling a trailer full of horses. The vehicle was towed to the contact's parent's residence. The vehicle was diagnosed by an independent mechanic and was diagnosed with a failed torque converter. The contact was informed that the torque converter needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 129,000.

Rainy road, 60mph on the hw with my family. Truck decides to engage stabilitrak or something to that feel and locked up the brakes. Talk about a scary moment with an 18 wheeler coming in hot behind you. Obviously, in the moment, I had no clue what was happening other than something with the truck was malfunctioning. This scenario could have gone wrong in so many ways. I'm honestly in shock someone has not been killed because of this?

When I turn the steering wheel, the ac turns off, lights turn off, the computer screen turns off, steering wheel gets hard and does a jerking movement. The truck turns off too and then suddenly turns on. This can cause a death. If this happens in a highway or a street where speed is high this can easily cause a death.. fortunately this has happened going at 30 mph and no one close at the time and also at a drive through fast food restaurant. It has not been confirmed by the dealer but I will soon have to take it. The only light that comes up is the StabiliTrak.. but it only lights up when it happens and then it goes away.

THE VEHICLE IS STALLING WHEN BRAKING AND GETTING READY TO TURN. MY TRUCK IS SHOWING STABILITRAK SERVICE INTERMITTENTLY AND I'VE ALMOST BEEN IN A CRASH 3 TIMES BECAUSE OF THIS. THE VEHICLE ONLY RESTARTS AFTER PLACING IN PARK. THIS IS NOT SAFE WHEN IN TRAFFIC. THERE SEEMS TO BE NO RECALLS AND NO KNOWN CAUSE. SOMEONE IS GOING TO DIE IF GM DOESN'T FIX THIS. I'VE BEEN ON FORUMS AND IT'S A COMMON PROBLEM. IT SHOULD BE FIXED BY GM IF IT IS SO COMMON. THIS HAPPENS WHEN APPROACHING CROSS TRAFFIC AT AN INTERSECTION AND I LOSE ALL CONTROL OF STEERING BRAKING AND POWER TO THE TRUCK.

VEHICLE IS SHUTTING OFF AT ANY GIVEN SPEED, IE. 35 MPH IN TOWN OR 70 MPH ON A HIGHWAY WITH ONCOMING TRAFFIC. WHEN VEHICLE SHUTS OFF, LOSS OF ALL CONTROL OF THE VEHICLE TAKES PLACE. NO BRAKES, NO STEERING, NOTHING UNTIL THE VEHICLE RANDOMLY TURNS BACK ON. THIS IS NOT A CONSISTENT OCCURRENCE TO KNOW WHEN IT IS GOING TO HAPPEN OR BE PREPARED FOR IT TO HAPPEN. I WATCHED MY HUSBAND SHOOT ACROSS THE ROAD INTO THE OTHER LANE AND ALMOST PUT THE VEHICLE OVER A BANK ONE NIGHT WHEN IT HAPPENED. THIS HAS BEEN AN ISSUE SINCE JANUARY 2018 FOR US, WE HAVE TAKEN IT TO THE DEALER WHERE IT WAS PURCHASED MULTIPLE TIMES FOR THEM TO TELL US THEY CAN'T DUPLICATE THE ISSUE AND NOTHING IS COMING UP IN THEIR SYSTEM FOR AN ERROR CODE. IT HAS CAUSED A MAJOR INCONVENIENCE FOR MY FAMILY, AS WE DON'T DARE PUT OUR CHILDREN IN THE TRUCK LEAVING THE RESPONSIBILITY SOLELY ON ONE PARENT TO TRANSPORT THE KIDS TO AND FROM DAYCARE. I WORRY FOR THE SAFETY OF MY HUSBAND ON A DAILY BASIS.

TRUCK HAS 3 PROBLEMS THAT CAN PUT MY FAMILY'S LIFE IN DANGER. 1- SOMETIMES OUT OF NOWHERE AT LOW SPEEDS WHEN YOU TURN THE STEERING WHEEL TO MAKE A LEFT OR RIGHT TURN THE 'STABILITRAC' LIGHT FLASHES IN THE SCREEN AND LOCKS AND WON'T LET YOU TURN THE STEERING WHEEL.AT THIS POINT YOU HAVE NO CONTROL OF THE STEERING WHEEL, IT LOCKS AND BOUNCES BACK AT YOU AND IF YOU KEEP TRYING TO TURN IT, THE ENGINE CUTS OFF ALL POWER AND IT STALLS, JUST DIES. I ALMOST GOT READ ENDED A COUPLE OF TIMES ALREADY DUE TO THIS PROBLEM. JUST THIS MORNING I WAS MAKING A RIGHT ONTO A LOCAL MCDONALD'S AND THE STEERING WHEEL LOCKED AND THE ENGINE DIED ON ME. I HAD TO QUICKLY TURN IT ON AGAIN AND KEEP GOING.ANOTHER TIME IT HAPPEN AS I WAS MERGING INTO TRAFFIC. VERY SCARY! PROBLEM NUMBER TWO, I THINK ITS JUST A MATTER OF TIME BEFORE THE STEERING WHEEL LOCKS ON ME ON HIGH SPEEDS. SOMETIMES WHEN I'M ON THE FREEWAY, THE SAME CHIMES COME ON WHEN I STEP ON THE BRAKES, THE CENTER SCREENS GOES BLACK, AND THE SAME 'STABILITRAC' WARNING COMES ON THE SMALLER SCREEN BEHIND THE STEERING WHEEL. I'M AFRAID TO TAKE IT ON A WINDING ROAD FOR FEAR THAT THE STEERING WHEEL WILL LOCK ON ME CAUSE AN ACCIDENT. 3- SERVICE BRAKE CONTROLLER SIGN AND CHIMES COME ON ANT WON'T GO AWAY. IT JUS KEEPS ON POPPING ON AND ON AND ON AND THEY GO AWAY WHEN YOU TURN OFF THE TRUCK, AND COME ON AGAIN MONTHS OR WEEKS LATER. I DID HAVE IT CHECKED AT MY LOCAL DEALERSHIP.THEY TESTED IT, SOLD ME NEW GROUND AND HOT WIRES. IT WAS GOOD FOR ABOUT 4 WEEKS BEFORE THE SAME PROBLEMS CAME BACK AGAIN. I DID SOME RESEARCH ON SOME OF THE FORUMS AND YOU TUBE VIDEOS AND BY FAR I'M THE ONLY ONE WITH THE SAME PROBLEM. VERY AFRAID TO CAUSE AN ACCIDENT.

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.

HAS HAD AN ISSUE WITH ACCESSORIES FLASHING OFF AND BACK ON. REPORTED IT TO A GMC DEALER AND THEY WERE UNABLE TO DUPLICATE BUT SAID THAT THE BATTERY WAS BAD AND MOST LIKELY WHAT WAS CAUSING IT. IT DID FINE FOR A WHILE THEN BEGAN DOING IT AGAIN. THIS TIME HOWEVER IT CAUSED A LOSS IN POWER STEERING AND I ENDED UP IN THE DITCH. LATER IT DID IT IN A PARKING LOT AND WAS ABLE TO VIDEO TAPE IT. TOOK IT TO THE DEALER AND SHOWED THEM THE VIDEO. THEY WERE UNABLE TO DUPLICATE FOR 4 DAYS WHILE I WAS PAYING FOR A RENTAL BECAUSE MINE WASN'T SAFE TO DRIVE. ON THE FOURTH DAY I PROVIDED THEM WITH A SERVICE BULLETIN I FOUND THAT ADDRESSED THE ISSUE AS BEING A FLUCTUATION IN POWER AND FOR THEM TO CHECK THE CABLES AND DO A DROP LOAD TEST. THEY DID AND IT FAILED. I THEN HAD TO PAY 376.00 TO REPLACE THEM PLUS HAVING TO PAY FOR A RENTAL AFTER ASKING FOR A LOANER. THIS IS A PROBLEM A LOT OF PEOPLE ARE HAVING. JUST A QUICK GOOGLE SEARCH MAKES THAT PLAIN. GM ISN'T WANTING TO ADMIT IT. I HAVE THE VIDEO BUT I DON'T THINK IT WILL ALLOW ME TO UPLOAD IT TO THE FORM.
