VEHICLE SPEED CONTROL
AFTER APPLYING BRAKE TO SLOW DOWN TO < 5 MPH (NOT COMING TO A HALT) AND THEN TRYING TO ACCELERATE, VEHICLE BECOMES UNRESPONSIVE FOR 1 TO 2 SECONDS; IT FEELS LIKE THE TRANSMISSION GOES INTO NEUTRAL DURING THE BRAKING PERIOD AND WHEN GAS PEDAL IS APPLIED, THERE IS A 1 - 2 SECOND TIME PERIOD WHERE VEHICLE IS TRYING TO FIGURE OUT SOMETHING AND PREVENTS ANY ACCELERATION. WHY IS THIS DANGEROUS? I FOUND MYSELF IN A LEFT TURN ONLY LANE/GREEN LIGHT WITH OPPOSING TRAFFIC, AND I ATTEMPTED THE LEFT TURN WITH ONCOMING TRAFFIC BECAUSE I THOUGHT THAT I HAD AMPLE TIME BUT THE VEHICLE JUST SAT THERE FOR 1 - 2 SECONDS, AND WITH THAT I FOUND MYSELF IN A DANGEROUS PREDICAMENT BECAUSE THE ONCOMING TRAFFIC WAS GETTING VERY CLOSE. IF THE VEHICLE HAD RESPONDED WHEN I NEEDED IT TO, IT WOULD NOT HAVE BEEN A CLOSE CALL. THIS BEHAVIOR WITH THE VEHICLE CAN BE REPRODUCED AT WILL, EVERY TIME. THERE ARE MANY FORUMS ON THE INTERNET WHERE MANY PEOPLE ARE COMPLAINING ABOUT THIS SAME ISSUE WITH THE DRIVE-TRAIN, GMC KNOWS ABOUT IT, BUT REFUSES TO DO ANYTHING ABOUT IT.

WHILE DRIVING ON INTERSTATE THE ENGINE SHUT DOWN TO 1/2 POWER AND BEGAN TO SHAKE/VIBRATE. THE TOP SPEED THEN WAS ABOUT 40MPH. I FINALLY PULLED OVER AND READ MANUAL ON HOW TO RESET IT. IT WORKED PROPERLY THEN. THIS HAS HAPPENED 4 OTHER TIMES. THE LATEST INCIDENT HAPPENED YESTERDAY, WITH OUT USING CRUISE CONTROL. TRAVELING AT 30 MPH IT SHUT ME DOWN AGAIN . ONE OF THE SCARIEST TIMES , I WAS TRAVELING IN 5 LANES OF TRAFFIC AND IT SHUT ME DOWN TO HALF POWER AND IT WAS QUITE DANGEROUS FOR US TO TRY AND MERGE OUT OF THE WAY AND GET OFF TO A SAFE SPOT ON SIDE OF INTERSTATE. I CALLED THE DEALER AND THEY TOLD ME THERE HAS NOT BEEN A RECALL ON THIS ISSUE, BUT IT SEEMS VERY MUCH LIKE A SAFETY ISSUE WITH ME. THE DEALER ALSO TOLD ME AS WELL AS OTHER AUTO SPECIALIST IS THAT THIS IS A COMMON PROBLEM WITH THIS MODEL OF VEHICLE AND THAT IT WILL COST ABOUT 700 DOLLARS TO REPLACE THE THROTTLE CABLE ASSEMBLY.

THE ACCELERATOR PEDAL ON THE PICKUP HAS AND STILL DOES STICK WHEN TRYING TO ACCELERATE SLIGHTLY/SLOWLY FORWARD OR BACKWARD AS IN PARALLEL PARKING. THE PROBLEM IS WORSE IN HOT WEATHER. THE DEALER, DURING WARRANTY PERIOD, TOLD ME THEY FOUND NO DEFECT AND KNEW OF NO DEFECT. I LEFT IT GO. MY FRIEND WHO OWNS A SATURN SEDAN TOLD ME HE HAS THE SAME PROBLEM WITH THE ACCELERATOR STICKING DURING SMALL MANEUVERS. I HAVE JUST READ THAT THERE ARE TWELVE COMPLAINTS SIMILAR TO MY ISSUE THAT HAVE BEEN REPORTED TO YOUR AGENCY. I AM REPORTING THE SAME AT PRESENT THOUGH THE PROBLEM HAS BEEN ONGOING FOR TEN YEARS. IT MAKES CLOSE PARKING DIFFICULT AND I TRY TO AVOID THE SITUATION BECAUSE OF SUCH. I HAVE ALMOST CRASHED MANY TIMES BECAUSE OF THE AMOUNT OF OVERPRESSURE TO THE ACCELERATOR TO MAKE THE TRUCK MOVE.
