LEFT VEHICLE PARKED ON INCLINE WITH PARKING BRAKE SET. RETURNED TO VEHICLE, STARTED ENGINE, RELEASED PARKING BRAKE , PUT VEHICLE IN DRIVE. THE GEAR INDICATOR ON THE DASH SHOWED THE CAR WAS IN DRIVE. THE GEAR SELECTOR IN CENTER CONSOLE INDICATED IT WAS IN DRIVE. STEPPING ON GAS RESPONDED WITH ONLY INCREASED RPM. VEHICLE BEGAN TO ROLL RAPIDLY IN REVERSE. THE POWER STEERING AND POWER BRAKES WERE NOT WORKING (ALMOST LIKE IT WAS IN PARK). THE VEHICLE WAS NEARLY UNCONTROLLABLE AND ALMOST RESULTED IN SEVERE INJURY AS A COUPLE AND THEIR DOG WERE WALKING BEHIND VEHICLE ON SIDEWALK AT TIME OF INCIDENT. AFTER EXERTING A SIGNIFICANT AMOUNT OF FORCE ON THE BRAK PEDAL THE VEHICLE STOPPED. I APPLIED THE PARKING BRAKE AND SHIFTED TO PARK. SHIFTED BACK TO DRIVE WITH THE SAME RESULT ROLLING BACK FURTHER NEARLY HITTING A BRICK MAILBOX. I THEN PUT TH CAR IN PARK AND TURNED IT OFF RESTARTED AND SHIFTED BACK TO DRIVE, THE VEHICLE THEN PERFORMED AS EXPECTED. VERY FORTUNATE THIS INCID T WAS NOT A DEADLY ACCIDENT. THIS SAME PROBLEM EXHIBITED ITSELF ON LEVEL GROUND ON W PREVIOUS OCCASION BUT WAS DISMISSED AS AN ISOLATED INCIDENT, BUT IT HAS HAPPENED MULTIPLE TIMES NOW.
