NHTSA Complaint #11240517 — 2015 SUBARU FORESTER

I DROVE INTO GARAGE AT ABOUT 1 M.P.H. AND PUT THE CAR IN PARK. AFTER IDLING FOR ABOUT 3 SECONDS THE ENGINE ACCELERATED TO 2,800 R.P.M. AND STAYED THERE,I COULDN'T GET IT TO SLOW DOWN. I PRESSED ON THE ACCELERATOR MANY TIMES,IT WOULDN'T SLOW DOWN OR SPEED UP. IT JUST STAYED AT THE SAME SPEED. PRESSING THE BRAKE PEDAL DIDN'T DO ANYTHING. I GOT IT STOPPED BY TURNING OFF THE IGNITION. WHEN THIS HAPPENED THE CHECK ENGINE LIGHT CAME ON. I GOT CODE P2138. I AM REPLACING THE ACCELERATOR PEDAL POSITION SENSOR AS I AM AFRAID TO DRIVE IT.THE CAR IS EXACTLY 5 YEARS OLD,I BOUGHT IT NEW. IT HAS 16,552 MILES ON IT NOW. I WAS VERY LUCKY IT WAS IN PARK WHEN IT DID THIS. I HOPE THE NEW PART FIXES IT.AFTER 4 RESTARTS THE CHECK ENGINE LIGHT WENT OUT. I TOOK IT FOR A SHORT DRIVE,AND THE ENGINE KEPT WANTING TO RUN FAST. TWO DAYS LATER IT SEEMS OK,IT SLOWS DOWN NOW.
