Engine problems of the 2004 Ford Expedition

2003 Ford f250 and 2004 Ford Expedition. Consumer states right rear spark plug blew out of the cylinder head. This happened on both vehicles the consumer was informed an adapter was made as a temporary fix. About 500 miles later, the same problem happened again. The consumer took the vehicle to a repair shop where the mechanic stated the heads or engine would need to be replaced at a cost of $3000-$4000.

Engine hood insulator material began to smolder and smoke. Needed to remove before vehicle caught fire. Burned two fingers.

Starting vehicle spark plug broke loose,damaging threads for spark plug and breaking coil pack. This is the second time this has occured. First time the vehicle was at freeway speeds and blew the spark plug out into the engine compartment. The spark plugs had never been changed before the first incident. In order to fix the problem the spark plug hole will have be repaired before a new plug can be put in.

The contact owns a 2004 Ford Expedition. While parked three sparks plugs/engine misfired. The failure caused $1700. 00 worth of damage. The vehicle was towed to the Ford dealer and all of the wires under the cylinder head were repaired. The failure mileage was 119,680.

My vehicle's engine has failed. The dealer will not honor the warranty claiming I didn't change the oil, they have no record of me coming in for maintenance, I change my own oil and brought receipts in. This was not good enough. They have had my vehicle for 18 weeks with no rental. I have contacted the company the bbb a news channel in my area and I also work for Ford which makes it even worse that they are denying my claim.

2004 Ford Expedition. Since I took delivery, the vehicle has a rough idle in any gear once the vehicle has been brought up to operating temperature (approximately 15 minutes). The truck has been returned to original dealership twice for this problem. The original "solution" was stated that due to the change in gas types from summer to winter the difference in oxygen in the fuel was causing the problem. I was told to drive it using a mid-grade gas for approximately 30 days and if the problem was still present return it to the dealer. The vehicle now has about 5,900 miles on it and the rough idle continues after it warms up. The vehicle is only getting about 10. 6 mpg which is significantly less than mfg stated and less than the 1997 4. 6l Expedition I previously owned. I returned the vehicle to the dealer approximately 30 days from the original visit complaining of the same rough idle problem and reduced mileage. On the second visit the dealer said all "electronic" checks were in spec and there was nothing "wrong" with the vehicle. Said they would have to turn it over to Ford engineer. We are waiting to hear from Ford. The car idles rough and the mileage is poor. Still no resolution to original problem.
