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
2007
POWER TRAIN:AUTOMATIC TRANSMISSION
DRIVING MY 2007 GMC ACADIA. WENT TO PASS A SLOWER VEHICLE, PRESSED ON THE ACCELERATOR TO PASS AND THE TRANSMISSION WENT HAYWIRE AND THE ACCELERATOR STUCK. I HAD TO PUT THE CAR IN NEUTRAL TO GET IT STOPPED. THE RPMS WERE IN THE 4000S. THEN THE ACCELERATION WOULD STOP AND START AGAIN OVER TO 4000. LUCKILY WHEN I PASSED THE VEHICLE THERE WERE NO CARS IN FRONT OF ME OR I WOULD HAVE HAD A MAJOR ACCIDENT WITH THE ACCELERATION OUT OF CONTROL. I TOOK IT TO THE DEALER AND THEY TOLD ME THAT TWO OF THE TIMING CHAINS WERE VERY WORN AND THERE WAS AN ISSUE WITH THE CLUTCH PRESSURE CONTROL WITH HARSH SHIFTS IN DRIVE RANGE 3RD AND/OR 5TH GEAR. THIS IS THE SECOND TIME I HAVE HAD PROBLEMS WITH THIS ISSUE. THE FIRST TIME THE GMC DEALER 'FLASHED' (REPROGRAMMED) THE TRANSMISSION, EVEN THOUGH IT WAS NOT ACTING UP WHEN THE CAR WAS TAKEN INTO THE SHOP. IF THIS ISSUE IS NOT ADDRESSED "PROPERLY", I BELIEVE SOMEONE SOMEWHERE WILL BE INJURED OR KILLED. THE CONDITION MY VEHICLE EXHIBITED LEAVES ME WITH A VERY UNEASY FEELING. *TR
