2007 GMC Acadia Speed Control & Cruise Problems

CAN'T GO OVER 25 MPH SEEMS TO BE STUCK ON ONE SHIFT WHEN IN TRAFFIC.

WHILE TRAVELING DOWN HIGHWAY, CAR DISPLAYS MESSAGE "SERVICE STABILITRACK ENGINE POWER REDUCED". CAR SLOWS DOWN AND SHAKES. TURNING CAR OFF FOR A FEW MINUTES THEN TURNING BACK ON CLEARS ISSUE, HOWEVER, HAPPENS MULTIPLE TIMES DAILY. VERY DANGEROUS WHILE TRAVELING ON HIGHWAYS OR FREEWAYS. *JS

AFTER TAKING MY VEHICLE TO PHIL MOORE BUICK GMC ON 10/16/2014 AND PAYING $1341.10 FOR REPAIRS AFTER A CHECK ENGINE LIGHT INDICATOR, THE CHECK ENGINE LIGHT CAME ON AGAIN ON 10/20/2014 AND CAUSED THE VEHICLE TO SLOW FROM 60 MILES PER HOUR TO 20 MILES PER HOUR ON THE HIGHWAY. WHEN THE VEHICLE WAS RETURNED TO THE DEALERSHIP ON10/21/2015, I WAS TOLD THERE WERE ADDITIONAL REPAIRS NEEDED ON THE ENGINE AT AN ESTIMATED COST OF $2789.18. BECAUSE REPAIRS HAD JUST BEEN COMPLETED ON THE SAME AREA 5 DAYS EARLIER, I CALLED THE GM CORPORATION AND I WAS INFORMED THAT REPAIRS TO THE ENGINE SHOULD HAVE BEEN COVERED UNDER A RECALL AND THE DEALERSHIP SHOULD HAVE NOTICED THE RECALL AT THE TIME OF SERVICE. *TR

I WAS TRAVELING AT APPROX 40 MPH IN TOWN, THE VEHICLE FELT LIKE IT BOGGED DOWN, ODOMETER STILL SHOWED 40MPH BUT I WAS NOT GOING ANYWHERE, CAR BEHIND ME SLAMMED ON THEIR BRAKES, CAR BEHIND HIM SLAMMED ON THEIR BRAKES, I WAS HONKED AT ALL THE WHILE I AM PUSHING ON THE ACCELERATOR, AFTER 10 OR 12 SECONDS IT WENT FORWARD WITH THE RPM'S GOING VERY HIGH AND MPH WENT TO 50 AND BACK TO 40 IMMEDIATELY AND I WENT FORWARD. IT SCARES ME TO DRIVE THIS CAR AND FROM WHAT I HAVE READ JUST TODAY, I AM NOT THE ONLY ONE HAVING THE PROBLEM. PLEASE DO SOMETHING ABOUT THIS BEFORE SOMEONE IS REALLY HURT. *TR

MY CAR WOULD NOT GO OVER 40 MPH ON A HIGHWAY AND THE RPMS WERE SHOOTING UP TO 9,000. I SAFELY MADE IT TO A PARKING LOT AND WHEN I WENT TO LEAVE THE CAR WOULD NOT MOVE IN REVERSE! I HAD TO PUSH THE CAR, WITH MY 5 CHILDREN IN IT, OUT OF THE SPOT!! (I'M A TOUGH CHICK BUT THIS WAS CRAZY!). I GOT THE CAR OUT OF THE LOT AND WAS ABLE TO SLOWLY MAKE IT HOME. MY CAR IS ONLY 10 MONTHS PAST WARRANTY AND WE WILL BE STUCK WITH A BIG BILL. I THINK IT SHOULD BE COVERED OR GMC SHOULD REIMBURSE THE REPAIR FEE. *TR

ON MONDAY, WITH MY CHILDREN IN THE CAR, I STARTED NOTICING THAT THE CAR WAS NOT SHIFTING CORRECTLY. I DID NOT THINK MUCH ABOUT IT. THEN ON THE WED OF THAT WEEK AS I WAS DRIVING IN A MAJOR CITY DOWNTOWN AREA FOR THE MORNING COMMUTE, THE ENGINE LIGHT CAME ON... I WAS AT A STOP TRIED TO ACCELERATE AND THE RPM'S REVVED. STEPPED ON THE GAS AND THE CAR WOULD ONLY GO 1 TO 2 MILES AN HOUR THEN SPEED UP ... DEALER SAID THAT THERE WERE "MANY PARTS IN THE PAN" AND THAT I NEEDED TO HAVE TRANSMISSION REPLACED. $3600 PLUS TAX OR HAVE IT REBUILT $3300 PLUS TAX. CALLED GM AFTER READING THE VARIOUS POST ON EDMUNDS ABOUT THE ACADIA PROBLEMS. THEY WERE VERY NICE AND OPENED A CLAIM BUT AS OF YET, NO ONE EVER CALLED ME BACK. WHEN THEY OPENED THE CLAIM THEY SAID SOMEONE WOULD BE IN TOUCH WITHIN 2 BUSINESS DAYS (AND THEY WOULD SEE WHAT THEY COULD DO ON SAVING ME SOME MONEY ON THE BILL) AS I WAS DUE BACK AT THE DEALERSHIP TO PICK UP MY CAR. *TR

I WAS DRIVING HOME FROM WORK AROUND 5:05PM ON THE 5 NORTH FREEWAY GOING ABOUT 65 MPH. ALL OF A SUDDEN MY CHECK ENGINE LIGHT WENT ON AND I FELT A SUDDEN LOSS OF POWER IN MY ACCELERATION. AS I STEPPED ON THE GAS MORE TO KEEP UP WITH THE FLOW OF TRAFFIC, THE RPM NEEDLE JUMPED UP TO BETWEEN 4 AND 6 ON MY GAUGE, BUT MY VEHICLE WASN'T GOING ANY FASTER SO I HAD TO STEER TO THE RIGHT TO GET TO THE EXIT. I WAS BARELY ABLE TO EXIT WITHOUT ALMOST GETTING REAR ENDED BUT I HAD NO CHOICE AS MY VEHICLE WOULD NOT GO OVER 40MPH. AFTER GETTING IT CHECKED AT THE NEAREST SHOP, I WAS TOLD THAT IT WAS A STUCK SOLENOID. AFTER I GOT THAT FIXED, 4 MONTHS LATER, SAME PROBLEM, BUT NOW THE DEALERSHIP IS TELLING ME THEY WILL HAVE TO REBUILD MY TRANSMISSION DUE TO A BROKEN WAVE PLATE, WHICH WILL COST ME AT LEAST $2800, WHICH I DON'T HAVE. *TR

GOING DOWN HIGHWAY AND TRANSMISSION STARTED ACTING UP. COULDN'T GO OVER 25 MPH AND HAD NO REVERSE. HAD NEW TRANSMISSION PUT IN AND THAT DID NOT FIX THE PROBLEM. *TR

WHEN WE WERE LOOKING AT THE GMC ACADIA AND GOING OUT FOR A TEST DRIVE, WE MENTIONED TO THE SALES REP THAT THE ACCELERATION WAS VERY SLUGGISH. HE RESPONDED THAT IT TAKES MILEAGE TO WARM THE VEHICLE UP. WE HAVE 15,000 MILES ON THE VEHICLE AND IT STILL IS SLUGGISH. WE HAVE BROUGHT THE VEHICLE BACK TO THE DEALERSHIP 4 TIMES TO RESOLVE THIS ISSUE. DRIVING IN THE RAIN AND/OR SNOW IS VERY HAZARDOUS, AND GOING UP HILLS, SINCE IT LACKS ACCELERATION, IT CAUSES THE TIRES TO SPIN OUT. WE HAVE GOTTEN STUCK GOING UP A HILL IN RAINY AND/OR SNOWY CONDITIONS. THIS IS VERY DANGEROUS AND NEEDS TO BE FIXED ONCE AND FOR ALL. *TR
