I DROVE AROUND THE REAR OF MY HOME WHICH IS WHERE MY GARAGE IS LOCATED. I CAME TO A COMPLETE STOP. I ACTIVATED MY GARAGE OPENER FROM MY VEHICLE. ONCE THE GARAGE DOOR COMPLETED OPENED I TOOK MY FOOT OFF THE BRAKE PEDAL AND ALL OF A SUDDEN MY CAR ACCELERATED TO A HIGH SPEED. I COULD NOT STOP THE CAR. THE CAR JUMPED A 9 INCH LEDGE AND I CRASHED THROUGH MY GARAGE WALL, AND INTO MY BASEMENT AND THE CAR FINALLY STOPPED IN MY BASEMENT WHEN IT HIT MY COMPUTER DESK. *NM

THE A/C SYSTEM STINKS DUE TO WATER RETENTION IN THE HEATER WHICH CAUSED MOLD. THE DEALER COULD MASK THE ODOR BUT COULD NOT ELIMINATE IT. A LOUD BANG OCCURRED WHEN THE VEHICLE WAS STARTED IN COOL OR COLD WEATHER. THE DEALER INDICATED IT WAS DUE TO AN ELECTRICAL SPIKE. THE VEHICLE EXPERIENCED SUDDEN ACCELERATION WHILE MERGING INTO TRAFFIC. THE BRAKES ROTORS HAVE FAILED THREE TIMES, EVERY 20000 MILES ON AVERAGE. *NLM *NLM

OUR IMPALA HAS HAD A PROBLEM WHERE IT HESITATES AND STUMBLES WHEN YOU TRY AND ACCELERATE SINCE IT WAS NEW. THE DEALER HAS NOT BEEN ABLE TO IDENTIFY THE CAUSE. THIS A HAZARD! I THINK WE SHOULD GET OUR MONEY BACK BUT THEY KEEP GIVING US THE RUN AROUND "YOU BOUGHT AND NOW IT'S YOURS". I THINK THAT STINKS! I SEE OTHER COMPLAINTS CONCERNING THIS PROBLEM ON YOUR WEB SITE, CAN'T YOU GUYS CONTACT GM AND DEMAND THEY DO SOMETHING ABOUT THIS?*AK

CAR ROLLS BACKWARD WHEN ENGINE RUNNING AND FOOT TAKEN OFF BRAKE TO GO FORWARD. REQUIRES THE BRAKE TO REMAIN ENGAGED AND GAS PEDAL PRESSED AT SAME TIME.
