SLOWLY PULLED CAR INTO THE DRIVEWAY. ENTERED THE GARAGE WITH MY FOOT ON THE BRAKE. HALF WAY INTO GARAGE, THE ENGINE OVER ACCELERATED AND MADE THE CAR LUNGE FORWARD. MY FOOT WAS STILL ON THE BRAKE PEDAL. THE BRAKES WENT INTO ABS MODE, WITH PULSATING. THE CAR RAMMED INTO SOME STORAGE TOTES AND ALSO MY SNOWBLOWER. THE OVER ACCELERATION OF THE ENGINE STOPPED. ALL OF THIS TOOK ABOUT 10 - 15 SECONDS. NO AMOUNT OF PRESSURE ON THE BRAKE PEDAL STOPPED THIS CAR. NO, I DID NOT HAVE MY FOOT ON THE GAS PEDAL. THE CAR WENT INTO MY LOCAL CHEVY DEALER 2 DAYS LATER. I WAS TOLD THAT THEY RAN SOME TESTS, HAD IT UP ON A LIFT & EVEN HAD A MECHANIC TAKE IT OUT TO TRY TO DUPLICATE THE PROBLEM. OF COURSE, THEY COULDN'T FIND ANYTHING WRONG. SOMEONE NEEDS TO DO SOMETHING ABOUT ALL THESE OVER & UNDER ACCELERATION PROBLEMS BEFORE LIVES ARE LOST! MY CAR HAS A FEW MINOR DENTS ON THE HOOD, FROM FALLING TOTES MY SNOWBLOWER IS SLIGHTLY DENTED BUT MY NERVES ARE SHOT. I AM REALLY SCARED TO DRIVE THIS CAR.
