Spark plugs blow out of cylinder heads on the 5.4 V-8 and on the V-10 motors as well. This has happened to me three times and Ford recognizes the problem. It needs to be investigated as this is a potential fire issue, and may result in loss of control.

The vehicle stalled without warning. The consumer had the vehicle towed to the dealer. The mechanic informed the consumer that the spark plugs blew out causing the engine to fail.

Interior lights malfunctioning, daytime running lights not working correctly, heating/cooling system not working properly; stays on even when key is not in ignition. When ignition is turned on or off, the woofer makes a loud thumping sound. Woofer inoperable. Right sign wing never worked properly/ will not open or close. Braking system is doubtful, it squeaks, and when gas is released engine and braking are not coordinated smoothly. Constant squeaking when in motion. Dealerships service repair personal neglect and refuse to find the causes, even though vehicle is still under warranty.

The passenger side cylinder head needed to be replaced to the very common spark plug blow out. From other websites I have seen this to be a very common occurrence among Expedition owners. The repair cost was in the area of $1800. Ford does not acknowledge this as a defect and yet it happens to people every day.

While driving could smell engine burning oil which came through the vents. There was no oil leaking. Coil broke in the engine/ windshield wipers would come on by themself, while the rear wiper does not work at all/ passenger door panel was loose & came off/ electrical system would cause lights to flicker on & off, and fuel gauge failed to register the correct amount of fuel when filled.
