2008 GMC Acadia vehicle speed control problems

“The traction control turns on and then the shifts don’t work and I can’t drive since there is no speed also the rpm and the gas the speed and the battery gages start flickering up and down then I turn off the truck and it continues to work fine but after 40 miles or so it does it all again”

“MY LIFT GATE DOOR FELL AND HIT ME IN THE HEAD OUT OF NO WHERE AND MY CAR IS NOT ON THE LIST FOR THE RECALL FOR THAT EXACT PROBLEM. MY AIRBAG INDICATOR GOES OFF ALL THE TIME EVEN IF NO ONE IS IN THE FRONT SEAT. MY SPEEDOMETER BARELY WORKS, IT GOES COMPLETELY AROUND AND I CAN'T GET IT TO RESET. I TOOK IT TO THE SHOP JUST TO BE TOLD IT'S A SENSOR THAT CAUSES IT ALONG WITH THE SLOW CRANKING BUT THEY DIDN'T KNOW WHICH ONE IT WAS BECAUSE MY CAR HAS 4.”

“TAKATA RECALL IT KEEPS SHUTTING COMPLETELY DOWN IN THE MIDDLE OF HIGHWAY AND THIS AFFECTS EVERYTHING STEERING, COMPLETE LOSS OF POWER TO VEHICLE. NO CODES TO INDICATE SOMETHING IS WRONG !!!! EXTREMELY DANGEROUS THIS HAS CONTINUED TO OCCUR EVEN AFTER PARTS HAVE BEEN REPLACED BRAND NEW. MORE THAN 5 TIMES ALREADY. THIS WILL MOST CERTAINLY LEAD TO DEATH. I HAVE 3 CHILDREN WITH ME AT ALL TIMES. THAT'S 4 LIVES THAT COULD BE LOST BECAUSE OF THIS PROBLEM!!!! . WE HAVE BEEN EXTREMELY LUCKY BECAUSE IT HAS SHIFT DOWN IN THE MIDDLE OF THE NIGHT AND BRIDGES WHERE THERE IS NOWHERE TO GET ON THE SIDE BUT REMAIN IN THE LANES WHERE TRAFFIC IS 70 MPH AND UP!!!! THIS NEEDS TO BE RECALLED IMMEDIATELY!!!! *TR”

“ON 4 SEPARATE OCCASIONS WITHIN A 3 WEEK PERIOD THE VEHICLE WOULD ACCELERATE WHILE DRIVING WITHOUT DRIVER PROMPTS OR CONTROL (RPMS REVVED FROM 2000 TO OVER 6000 AND SPEED WOULD INCREASE FROM 50 MPH TO OVER 85 MPH WITH ACCELERATOR PEGGED TO THE FLOOR.) THE ONLY WAY TO CORRECT THIS WAS TO PUT THE VEHICLE IN NEUTRAL, COAST TO THE SIDE OF THE ROAD, STOP THE VEHICLE AND TURN OFF THE ENGINE FOR 10-15 MINUTES, THEN RESTART IT AND IT WOULD RUN NORMALLY FOR SHORT PERIODS OF TIME. IF I DROVE THE VEHICLE FOR MORE THAN 30 MINUTES AT A TIME IT WOULD REACT THIS WAY EVERY TIME AND NEARLY CAUSED ME TO HIT 2 VEHICLES ON THE INTERSTATE. ON ONE OCCASION I HAD TO IMPACT A GUARDRAIL TO SLOW THE VEHICLE DOWN. I TOOK THE VEHICLE TO A CERTIFIED GMC DEALERSHIP WHO STATED ON BOTH OCCASIONS THEY COULD NOT REPEAT THE PROBLEM AFTER DRIVING IT FOR 5-10 MINUTES OR LESS THAN 15 MILES. WHEN I INFORMED THEM THAT IT ONLY OCCURRED AFTER 30-45 MINUTES OF DRIVING, THE TECHNICIAN STATED HE DIDN'T HAVE TIME TO DRIVE THE VEHICLE THAT LENGTH OF TIME OR DISTANCE AND WENT ON TO SAY NO DIAGNOSTIC CODES WERE TRIPPED SO THERE WASN'T ANY REPAIRS HE COULD DO OR THAT GMC WOULD AUTHORIZED. THE VEHICLE WAS UNDER…”

“THERE IS A RECALL ON THE CONVERTRR POST THAT CAUSES THE ENGINE TO SEIZE UP AND PULL TO GO INTO THE ENGINE.. WHEN STARTED NOTHING COMES OUT OF THE EXHAUST PIPES AS THEY ARE CLOGGED MAKING IT DANGEROUS TO OPERATE.. THE RECALL IGNORAMUS THIS YEAR, MAKE AND MODEL FOR THE SAME PROBLEM HOWEVER AFTER CONTACTING GMC REPEATEDLY THEY SAY THAT IT DOESN'T INCLUDE THIS EXACT VIN..I HAVE ALREADY HAD THE ENGINE REPLACED ONCE DUE TO THIS PROBLEM AND THER DEALER FAILED TO DIAGNOSE IT PROPERLY AND ACKNOWLEDGE THAT IT HAD THE SAME PROBLEM AS THE RECALL IN OTHER VEHICLES OFTHE SAME MAKE AND MODEL... THE VEHICLE SIZES UP AT ANY RATE OF SPEED AND THE EXHAUST IS CLOGGED MAKING THE VEHICLE DANGEROUS TO OPERATE”

“TRANSMISSION PROBLEM I AM BEING TOLD...NO WARNING SIGNS! STOPPED AT A RED LIGHT AND WENT TO ACCELERATE AND ACADIA WOULD NOT GO FASTER THAN 25 MPH! NOW I AM BEING TOLD I NEED A NEW TRANSMISSION AT 95000 MILES GMC IS A JOKE! WILL NEVER OWN ANOTHER ONE!”
