Two problems related to loud engine noise have been reported for the 1999 Ford F-250. The most recently reported issues are listed below.
Tl the contact owns a 1999 Ford F-250. When the contact exited and returned to the vehicle, it made an abnormal sound when it was restarted. Suddenly, a fire erupted under the hood, which spread to the cabin of the vehicle. The driver fell and hurt her knee while attempting to exit the vehicle quickly. Medical treatment was required. The fire was extinguished by the fire department. There was extensive damage to the front end of the vehicle. The insurance company was made aware of the failure. The manufacturer was notified. The dealer was not contacted. The cause of the failure was not determined. The VIN was not available. The approximate failure mileage was 300,000.
Upon starting my 1999 Ford F-250 super duty, with the 5. 4 triton engine, I heard a loud noise from under the hood. Turned the truck off and popped the hood. The passenger side of the engine was on fire. Extinguished fire with garden hose, and found the 3rd spark plug from the front on the passenger side of the engine had blown out of the cylinder head, driving the ignition coil into the fuel rail repeatedly. The fuel rail ruptured, and the gasoline ignited. Less than 12 months after repairing the truck, the 2nd spark plug on the passenger side was ejected from the cylinder head exactly as before, but without a fire this time. From my research online, I have found far too many vehicles with the 5. 4 triton engine with the exact same problem that I have experienced, and I am totally appalled and disgusted that such an obvious design flaw is allowed to remain immune to any form of accountability. Ford motor company should hang it's head in shame, as well as any/every one who turns a blind eye in this matter.
