Preparing to park into a parking space in an off street parking lot the vehicle forcefully and rapidly accelerated on its' own and crashed into a fence. I was not accelerating. I attempted to stop the car using the brakes but they did not engage quickly enough to stop the rapid, forceful, and without warning acceleration. Buick has been contacted about the defect. Buick ran extensive diagnostics on the car and denies there is a defect. Police came to the scene and advised that given the 2 other incidents that I have experienced, the car is unsafe to drive given potential damage to others. A police report was filed.

When pulling into parking space the car rapidly accelerated on its' own and crashed into the car in the next parking space. I did not have my foot on the gas, the car was simply idling. The acceleration was so rapid that applying the brake was useless.

NYB CAR HAS LESS THAN 69K MILES AND IS BURNING THROUGH OIL. I BOUGHT IT USED AND THE DEALER LIKED WARRANTY ENDED BEFORE PROBLEMS STARTED. MY CHECK ENGINE LIGHT CAME ON WITHIN THE FIRST 2000 MILES OF ME DRIVING AND THE DEALER WANTED TO CHARGE ME ANOTHER $200 FOR A DIAGNOSTIC. SO I WENT TO A MECHANIC AND HE SAID THE ENGINE WAS BURNING THROUGH OIL FASTER THAN IT SHOULD. AT THIS POINT THE CAR HAD TURNED OFF WHILE UNDER 10MPH TWICE WHICH IS DANGEROUS AS THE BRAKES LOCK UP ALONG WITH STEERING BECOMING VERY STIFF. A MECHANIC DID WORK ON THE CAR REPLACING PLUGS AND OTHER PARTS THAT HAD BEEN DAMAGED FUE TO THE OIL BEING GONE, BUT THE SAME ENGINE IS STILL IN THE CAR. NOW LESS THAN A YEAR LATER ALONG WITH REGULAR OIL CHANGES THE CAR STILL BURNS THROUGH OIL. THE ENGINE CAUSES THE CAR TO ROCK WHEN AT IDLE AND WHEN MOVING UNDER 5MPH. MY FEAR IS THAT IVE CAR WILL SHUT OFF AGAIN. THIS IS A FAULT OF BUICK FOR DESIGNING AN ENGINE THAT CAN'T HOLD OIL.
