PULLING INTO DRIVEWAY TO PARK INTO GARAGE, PRESSED ON THE BRAKE AND IT WENT ALL THE WAY TO THE FLOOR. PUSHED DOWN ON EMERGENCY BRAKE TO STOP THE TRUCK BEFORE IT HIT THE GARAGE WALL. *JS AFTER PLACING THE TRUCK IN PARK I OPENED THE HOOD TO SEE ONE OF THE BADLY RUSTED LINES CONNECTING TO THE FRONT DRIVER SIDE WHEEL LEAKING FLUID. INSPECTED ALL THE REST OF THE BRAKE LINES PERSONALLY ALL OF THE LINES ARE SEVERELY RUSTED LEADING TO ABS & MASTER CYLINDER.

NHTSA complaint #843785 — an unverified report by a vehicle owner.

VEHICLE SPEED CONTROL:ACCELERATOR PEDAL

THE ENGINE DOES NOT SLOW DOWN WHEN THE DRIVERS FOOT IS REMOVED FROM THE GAS PEDAL. THE ENGINE ACTUALLY SPEEDS UP SLIGHTLY, STAYS AT ABOUT 2000 RPM AND AFTER ABOUT 8 TO 10 SECONDS, IT GOES BACK TO NORMAL IDLE SPEED. THE ONLY WAY TO SLOW THE TRUCK IS TO PUSH IN THE CLUTCH AND APPLY THE BRAKE, THIS IS VERY IRRITATING AND DANGEROUS, ESPECIALLY IN CITY TYPE TRAFFIC. THIS WAS REPORTED WHEN THE TRUCK WAS NEW. IT HAS BEEN BACK TO THE DEALER 3 TIMES WITH NO IMPROVEMENT. THE DEALER SAYS WE HAVE TO CONTACT GM TO GET A NEW COMPUTER PROGRAM WRITTEN. GM SAYS WE HAVE TO GO BACK TO THE DEALER. WE ARE GETTING NOWHERE. THE DEALER AGREES THERE IS A PROBLEM THAT COULD BE A SAFETY HAZARD AND THAT OTHER CUSTOMERS HAVE REPORTED THE SAME PROBLEM. LAST SERVICE REPORT FROM DEALER SAYS "OWNER REPORTS THAT WHEN FOOT OFF GAS VEHICLE DOESN'T SLOW DOWN. TEST DRIVE CONFIRMED CONCERN. CAUSE TO BE NORMAL IAC (IDLE AIR CONTROL) THROTTLE FOLLOW ROUTINE. THIS IS NORMAL OPERATION AND NO FIX IS AVAILABLE". I FIND IT HARD TO BELIEVE THAT THE DEALER CANNOT GET GM TO ISSUE A COMPUTER REPROGRAM FOR THIS PROBLEM. THE DEALER WANTS US TO GO TO GM TO GET THEM TO ASSIGN AN ENGINEER TO WRITE A NEW COMPUTER PROGRAM. WE CALLED GM BUT NO HELP YET. I THINK OTHERS MUST HAVE THE SAME PROBLEM AND THIS PROBLEM SHOULD BE A RECALL.
