2017 GMC SIERRA 1500 Complaints

I WAS DRIVING 50MPH AND WAS BEHIND A SEMI AS I STARTED TO PASS HIM I NOTICED AN ONCOMING CAR AND DECIDED THERE WASNT ENOUGH TIME TO PASS SO I STARTED TO PUSH THE BRAKE PEDAL TO SLOW DOWN AND GET BACK BEHIND THE SEMI AND THE BRAKES LOCKED UP WHICH PRODUCED AN UNCONTROLLABLE SPIN IN WHICH I DID A 180 DEGREE SPIN AND ENDED UP GOING INTO THE DITCH BACKWARDS AND TIPPED OVER ON MY SIDE NO AIRBAGS DEPLOYED EITHER.

WHEN I APPLY THE BRAKES IT DOESN'T WANT TO STOP AND I HAVE TO PUSH IT DOWN AGAIN ALMOST LIKE THERE IS A ISSUE WITH THE VACUUM ON THE BRAKES BUT IT SAYS MY VEHICLE IS NOT AFFECTED BY THE RECALL BUT THE SYMPTOMS ARE EXACTLY THE SAME AS THE RECALL.

I HAVE AN 8 SPEED TRANSMISSION THAT STALLS UPON ACCELERATION LURCHES AND SURGES WHEN TRYING TO SHIFT GEARS. WHEN COMING TO A STOP LUNGES FORWARD DUE TO A SHIFT IN THE TRANSMISSION. I HAVE TAKEN TO THE DEALER MULTIPLE TIMES AND EXPRESS MY CONCERNS THEY FINALLY REPLACED TORQUE CONVERTER AND FLUSHED TRANSMISSION NOW THEY STATE THAT IT IS OPERATING CORRECTLY.

VEHICLE HAS HARD SHIFT BETWEEN FIRST AND SECOND GEAR ACCELERATING AND DECELERATION. I NOTICED IT AFTER ABOUT A WEEK OF DRIVING IT AFTER PURCHASE

WHILE WATCHING THE ECONOMY MILEAGE WINDOW I NOTICED IN THE LOWER RIGHT SIDE SHOWING V6 AND V4 SWITCHING BACK AND FORTH. AS THEY WERE SWITCHING, I NOTICED THE ENGINE VIBRATING WHILE SHOWING THE V4 IN THE WINDOW. IT DID NOT VIBRATE WHILE SHOWING THE V6 IN THE WINDOW. IT DID THIS WHILE I WAS DRIVING 65 MPH(ON CRUISE) ON THE EXPRESSWAY. I DID NOT NOTICE IT DURING DRIVING IN START-STOP SLOWER TRAFFIC.THIS HAS BEEN HAPPENING BEFORE, BUT DID NOT FIGURE OUT THE PROBLEM UNTIL NOW.

AS I WAS BACK MY BOAT IN AT BOAT RAMP BRAKE PEDAL WAS HARD TO PRESS DOWN HAD TO ALMOST STAND ON THEM TO KEEP FROM TRUCK GOING IN THE WATER. I RESEARCHED THIS AND SEEN WHERE GM HAS A RECALL ON THE VACUUM PUMP BUT I CALL THE DEALER THEY TOLD ME THEY WASN'T A RECALL.

GMC SIERRA WAS BROUGHT TO DEALER FOR EXISTING RECALL REGARDING BRAKING. DEALER INDICATED RECALL HAD BEEN RESOLVED. WHILE BACKING THE TRUCK ON 3 SEPARATE OCCASIONS SINCE RECALL ADDRESSED, BRAKES BECOME MUCH LESS RESPONSIVE WITH CLICKING SOUND. BRAKES BECOME HARD TO PRESS AND DO NOT STOP VEHICLE COMPLETE. THIS ALSO HAPPENED WHILE TOWING A BOAT DOWN RAMP. THE VEHICLE HAS 28,000 MILES AND THE ISSUE DID NOT OCCUR PRIOR TO ABOUT A MONTH AGO. THE MOST RECENT TIME WAS TONIGHT WHILE BACKING ON LEVEL GROUND INTO GARAGE. I HAVE NOT HAD AN ACCIDENT AS A RESULT OF THIS, BUT THE RECALL WAS NOT ADEQUATELY PERFORMED OR DID NOT ADDRESS THE ISSUE.

THE VEHICLE WAS IN MOTION ON A CITY STREET, WHEN THE VEHICLE COMPLETELY POWERED OFF. THE STEERING WHEEL LOCKED. THIS OCCURRED ON 11/22/2020 AND 11/23/2020. THE FOLLOWING MESSAGE IS ON MY DASHBOARD 'STEERING ASSIST IS REDUCED DRIVE WITH CARE.'

TL* THE CONTACT OWNS A 2017 GMC SIERRA 1500. THE CONTACT STATED THAT WHILE EXITING A PARKING LOT AND TURNING THE STEERING WHEEL COMPLETELY TO THE LEFT AND TO THE RIGHT, THERE WAS AN ABNORMAL SOUND COMING FROM THE DRIVER'S AND PASSENGER'S WHEELS. THE CONTACT COASTED TO THE SIDE OF THE ROAD AND NOTICED THE TIRES WERE RUBBING ON THE FRONT SUSPENSION BARS. THE VEHICLE WAS NOT TAKEN TO A DEALER. NEITHER THE DEALER NOR THE MANUFACTURER WERE MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 70,000.

ON FRIDAY NOVEMBER 6TH WE WERE ON OUR WAY HOME COMING DOWN 1960 EAST WHEN WE STARTED TO HEAR A NOISE COMING FROM THE TRUCK. WE COULD HEAR IT LOUD AND CLEAR BECAUSE THE A/C IS ALSO OUT SO WE HAVE BEEN HAVING TO LEAVE THE WINDOWS DOWN. IT SOUNDED LIKE AN OLD ELECTRIC FAN RUNNING. THEN SHORTLY AFTER THE TRUCK STARTED TO JERK HARD IT FELT LIKE WE HAD JUST BEEN IN AN ACCIDENT. THE TRUCK WOULD NOT SHIFT GEARS AND WE WERE IN THE MIDDLE OF A VERY BUSY 1960 LUCKY WE WERE CLOSE TO HOME AND WHERE ABLE TO MAKE IT THERE AFTER MULTIPLE ATTEMPTS TO GET THE TRUCK GOING. MY HUSBAND HAS SOME KNOWLEDGE OF CARS AND REALIZED IT WAS THE TRANSMISSION. THIS IS A FAIRLY NEW VEHICLE. HOW CAN IT HAVE SUCH A MAJOR PROBLEM? WHEN DOING SOME RESEARCH APPARENTLY THIS IS PROBLEM THAT GM IS AWARE OF AND HAVE DONE NOTHING TO FIX. AS I MENTIONED BEFORE THE A/C CONDENSER HAS A MAJOR LEAK AND THIS IS ALSO A PROBLEM OF GM VEHICLES. BASICALLY WE BOUGHT A BRAND NEW LEMON. I'M THANKFUL WE WERE NOT ON THE FREEWAY WHEN THIS HAPPENED IT COULD HAVE BEEN MUCH WORSE OUTCOME. FOR NOW WE ARE WITH OUT A VEHICLE AND CAN NOT AFFORD TO REPLACE THE TRANSMISSION.
