Owner report 10228539 · 2008-05-21 (May 21, 2008)
I WAS DRIVING ON THE INNER LANE OF THE FREEWAY AT 65MPH. THE ENGINE SUDDENLY STALLED AND THE CHECK ENGINE LIGHT STARTED FLASHING. I MANAGED TO HAVE THE CAR SLIDING TOWARD THE SHOULDER AND GET OFF FREEWAY. THE CAR WASN'T ABLE TO RESTART AGAIN. A HIGHWAY PATROL CAME BY AND HELPED TO PUSH MY CAR TO WILDER SHOULDER FOR SAFETY. THE REAR BUMPER WAS DAMAGED IN THE PROCESS. THE CAR WAS TOWED TO THE DEALER FOR INSPECTION AND STILL IN THE SHOP NOW. THE MECHANIST SAID THE ENGINE NEED TO BE REPLACED. *TR
