NHTSA Complaint #11484554 — 2007 ACURA MDX

The engine does not start at once and when the key is turned off to try again, the engine explodes and the upper part of the engine case is completely torn off. At this time, there was a huge explosion sound like a bomb exploding and a lot of black smoke came out. It's not really a rocket engine, which is a huge force, but I really don't understand how much pressure was applied in the engine of an ordinary car, so that the engine cover was broken by the explosion. Even if a person intentionally smashed the engine cover like this, it would be impossible. If such an accident occurred while running, it is thought that there would have been many casualties. Although it is an old car, it was used without any problems until yesterday, and it is understandable that the car does not start even if there is a problem. I think that such a big engine explosion produced a problematic engine by Honda Acura. There must be various engineering reasons for the explosion, but we believe that it is a problem that should never happen again by identifying the cause, so we report it with photos. Please investigate to find out the cause and prevent further accidents.
