NHTSA Complaint #10005329 — 2000 GMC YUKON XL

WHILE TRAVELING ON THE HIGHWAY WITH THE CRUISE CONTROL SET AT 72MPH, WHICH HAD BEEN ON AND IN PLACE FOR ABOUT 20 MINUTES, I LOOKED DOWN AND SAW THAT THE CAR WAS NOW GOING 85 - EVEN THOUGH I HAD NOT TOUCHED THE ACCELERATOR. I DECIDED THAT I WOULD HIT THE BRAKE A LITTLE TO DEACTIVATE THE CRUISE AND RESET IT. AFTER TOUCHING THE BRAKE, BUT BEFORE I PUT MY FOOT ON THE ACCELERATOR THE CAR WAS BACK UP TO 80 - 85. I PLAYED AROUND WITH THE CRUISE CONTROL SWITCH, HOPING TO STOP THE PROBLEM. NOTHING WORKED IN THAT REGARD, SO I THOUGHT I WOULD JUST GET OFF THE HIGHWAY, TURN THE CAR OFF (WHICH WOULD RESET EVERYTHING), AND START OVER. WHILE TRAVELING TO THE EXIT, WHICH WAS ABOUT TWO MILES, I HAD TO KEEP SIGNIFICANT PRESSURE ON THE BRAKES TO KEEP THE CAR AT AN ACCEPTABLE HIGHWAY SPEED. ONCE I PULLED OFF ONTO THE EXIT RAMP, I REALIZED THAT THE CAR WOULD NOT STOP. I WAS STANDING ON THE BRAKE WITH BOTH FEET TO GET IT SLOWED DOWN TO MAKE THE TURN OFF THE RAMP. SINCE THE CAR WOULD NOT STOP, I TRIED PUTTING THE CAR INTO NEUTRAL TO GET THE PULL OFF THE WHEELS, AT WHICH TIME THE RPMS RED-LINED. I TRIED ALL THE DIFFERENT GEARS, WHICH HAD THE SAME RESULT. I BRACED MYSELF FOR THE JOLT AND THREW THE CAR INTO PARK, NO JOLT - THE RPMS WENT TO RED-LINE. AT THIS POINT I WAS HEADED FOR A GAS STATION AND I TURNED THE CAR OFF. UPON SHUTTING THE CAR OFF, A HUGE PUFF OF BLACK SMOKE CAME OUT FROM UNDER THE HOOD, AND EVERYTHING SMELLED LIKE BURNING RUBBER. A TOW TRUCK TOWED US BACK TO THE DEALERSHIP, WHERE THEY HAVE BEEN OF NO HELP WHAT SO EVER.
