Consumer Description

ENGINE WILL INCREASE IDLE FROM 700 TO 900 AT ANY TIME. ONE CAN BE SITTING AT A TRAFFIC LIGHT AND IT MIGHT INCREASE OR DECREASE. I PULL A 5TH WHEEL (35 FEET) AND IT IS VERY DIFFICULT TO STOP WITH THE ENGINE TRYING TO KEEP GOING. ALSO IT IS VERY SCARY TO STOP ON SLIPPERY ROADS. THIS DID NOT START UNTIL THE VEHICLE HAD APPROX. 35,000 MILES ON IT. THE DEALER TELLS ME IT IS NORMAL, BUT I HAVE TALKED TO OWNERS OF THE GM DIESEL FROM MODEL YEAR 2008 THROUGH 2015 AND NONE OF THEM HAVE THIS CONDITION. *TR
