THE CAR ACCELERATED WHEN BACKING FROM A PARKING SPACE, HIT A POLE, I THEN PUT IT ON DRIVE AND IT ACCELERATED AT A VERY HIGH SPEED, I WENT TO BRAKE, IT HAD ALREADY HIT A PARKED DODGE CARAVAN IN THE PARKING SPOT DIRECTLY IN FRONT OF ME. I WAS ON BRAKE, CAR STILL CONTINUED TO MOVE. I MANAGED TO PUT IT ON NEUTRAL AND IT STOPPED. I TURNED OFF THE ENGINE. MY CAR HAD PUSHED THE PARKED DODGE 1.5 CAR LENGTHS. VAN TIRE SKID MARKS MEASURED BY HIGHWAY PATROL. NO INJURIES EXCEPT TO MYSELF, HIT MY KNEE AND MY HEAD. INDICENT REPORTED TO CA HWY PATROL, GEICO INSURANCE COMPANY, AND 49R SUBARU DEALERSHIP. CURRENTLY CAR IS AT THE DEARLERSHIP BEING EVALUATED FOR A MECHANICAL MALFUNCTION. I HAD TAKEN IT TO THE DEALERSHIP AT 60K MILES FOR POSSIBLE TRANSMISISION PROBLEM, IT SEEMED TO DOWNSHIFT AT LOWSPEEDS INAPPROPIATELY. NO PROBLEM FOUND.
