1998 Chevrolet Silverado 3500

SEVERAL TIMES THE TRUCK WHILE STOPPED AT AN INTERSECTION HAS ACCELERATED ON IT'S OWN AND PULLED ME INTO AN INTERSECTION. SEVERAL TIMES WHILE DRIVING DOWN THE ROAD AT 40 - 45 MPH THE TRUCK HAS ACCELERATED ON IT'S OWN TO OVER 70 MPH ON BACK COUNTY ROADS BEFORE I SHUT IT OFF AND COAST TO A STOP. UPON TRYING TO RESTART ENGINE IT WOULD REV UP TO 4000 RPM THEN FLUCTUATE FROM 1000 - 3000 RPM. AFTER SEVERAL RESTARTS IT WOULD RUN NORMALLY UNTIL THE NEXT OCCURRENCE. ONCE WHILE PULLING INTO A BANK PARKING SPACE THE TRUCK SUDDENLY ACCELERATED, BEFORE I WAS ABLE TO SHUT IT OFF IT JUMPED THE CURB AND WENT INTO THE SHRUBS. THIS PROBLEM HAS OCCURRED SEVERAL TIMES IN A 2 WEEK PERIOD BEGINNING LATE IN MARCH 2010. IT SEEMS VERY SIMILAR TO PROBLEMS ENCOUNTERED BY TOYOTA VEHICLES! *TR

TL*THE CONTACT OWNS A 1998 CHEVROLET K3500. THE CONTACT WAS MAKING A RIGHT TURN AT APPROXIMATELY 2 MPH WHEN THE VEHICLE ACCELERATED. THE BRAKES WERE ENGAGED AND EXHIBITED A JERKING MOTION. THE VEHICLE WAS DRIVEN ONTO THE EMERGENCY LANE. THE ENGINE WAS TURNED OFF. THE FAILURE OCCURRED SEVERAL TIMES. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC FOR DIAGNOSTIC TESTING WHICH INDICATED AN CODE REGARDING AN INCREASE IN THE RPMS. THERE WERE NO DIESEL MECHANICS IN THE AREA TO PERFORM THE REPAIR. THE VEHICLE HAD NOT BEEN REPAIRED AT THE TIME OF THE COMPLAINT. THE MANUFACTURER WAS NOTIFIED AND RECOMMENDED THAT THE VEHICLE BE TAKEN TO A DEALER. THE FAILURE MILEAGE WAS 114,500. THE CURRENT MILEAGE WAS 700,000.

THE PROBLEM I AM CONTACTING YOU ABOUT IS UNINTENDED ACCELERATION AFTER SELECTING REVERSE. I BROUGHT THIS VEHICLE IN TO MY SELLING DEALER 13 TIMES FOR THIS PROBLEM. GM WAS APPARENTLY AWARE OF THIS ISSUE AND CALLED IT AN "IDLE FLARE-UP". WHEN THIS VEHICLE HAD IT'S "IDLE FLARE-UP" IT WOULD SUDDENLY SURGE BACKWARDS 6 INCHES TO 6 FEET, DEPENDING ON THE SEVERITY OF THE "FLARE-UP" AND HOW QUICKLY I COULD GET THE VEHICLE STOPPED.SOMETIMES IT WOULDN'T DO IT FOR SEVERAL WEEKS, THEN IT WOULD DO IT 5 OR 6 TIMES IN ONE DAY.GM ENGINEERING HAD THE DEALER PERFORM 3 DIFFERENT TRANSMISSION REPAIRS TO ATTEMPT AND CORRECT THIS PROBLEM. A GM ENGINEER EVEN CAME OUT AND DROVE THE TRUCK ONCE, COULD NOT DUPLICATE THE CONCERN, (HENCE THE TERM "INTERMITTENT"), AND THEN DECLINED TO RECOMMEND A BUYBACK OR TRADE ASSIST. IT WAS SUGGESTED THAT PERHAPS I WAS MAKING THIS UP TO GET RID OF THE TRUCK. I AM A LANDSCAPE CONTRACTOR, DURING MY BUSIEST TIME OF YEAR, WASTING TIME AND ENERGY ON THIS MATTER. FURTHERMORE , IT HAS COST ME THOUSANDS OF DOLLARS TO GET RID OF THIS CHEVY AND PURCHASE A NEW FORD. GM HAS A PROBLEM THAT THEY ARE AWARE OF WITH THEIR 6.5 POWERTRAIN AND REFUSES TO ADDRESS IT.
