AS I WAS PULLING IN A BUSINESS CENTER TO PARK, I STEP ON THE BRAKE BUT THE CAR WOULD NOT STOP. THE ACCELERATOR CONTINUES AND CAUSED MY CAR TO RUN INTO A POWER BOX AT A BUSINESS. THIS CAUSED THE BUSINESS TO HAVE A POWER OUTAGE FOR THE ENTIRE DAY. THE WEATHER WAS CLEAR. IT WAS 11:30AM. THERE WAS NO CAR AROUND THE PARKING LOT MANY SPACES WERE EMPTIED. IM VERY FORTUNATE THAT THE CAR RAN INTO THE POWER BOX OTHERWISE THE CAR WOULD HAVE DRIVEN ITSELF INTO THE STREET! I'M A GREAT DRIVER FOR MORE THAN 20+ YEARS AND NO TICKETS OR ACCIDENTS. INSURANCE CARRIER HAD DECLARED AS TOTAL LOSS DUE FOR THE IMPACT. AIRBAGS DID NOT DEPLOYED.
