Driving on the highway, there was a pop and the car lost all propulsion. An original factory installed spark plug had blown out of its hole, damaging the cylinder head and destroying several coils, rendering the car undriveable and leaving me with a $4,000 repair job. From internet Honda chat boards, it is apparent that this problem has occurred in as many as 1 in 600 Honda Accords, generally with the number 5 spark plug on the v6 models.
