I ENTERED THE HIGHWAY AND MY POWER STEERING LIGHT CAME ON. I THEN LOST POWER STEERING. IMMEDIATELY GOT OFF AT THE NEXT EXIT AND PULLED INTO THE GAS STATION. AS I EXITED MY VEHICLE I OBSERVED SMOKE COMING FROM THE HOOD VENTS. THE ENGINE BAY THEN BECAME FULLY ENGULFED IN FLAMES AND THE FIRE DEPARTMENT RESPONDED TO EXTINGUISH THE FIRE. VEHICLE IS TOTAL LOSS.
