Vehicle lost power for 3-5 seconds at highway speeds approximately 65 MPH on three separate events. Vehicle slowed down due to power loss while in heavy traffic. Three other times at idle speed in drive and in park engine stalled and immediately restarted. Loss of power steering due to engine not running when stall event happened. I performed inspection of fuel pump relay which is internal to passenger side fuse block. Found inadequate solder joint on integrated relay printed circuit and burn marks on outside of fuel pump relay. Located salvage fuse block same make and model and inspected. Same damage on salvage fuse block assembly. Replaced with aftermarket fuse block with revised solder joint and updated relay.

Multiple and intermittent engine stoppage. The engine stalls suddenly while driving in traffic causing hazard to self and others. Sudden loss of power steering makes control of vehicle difficult as power steering is non functional as you attempt to pull to the side of a busy road. Braking systems also are mostly non functional without the vacuum created by the running engine making it very difficult to stop quickly. This presents a dire emergency condition for the surprised driver, and a hazard to other occupants as well as other drivers nearby. A driver who is small in stature may be unable to man-handle the stiff steering condition. Once stopped, the engine may restart right away or not, stranding occupants in unsafe conditions and cause an accident chain involving life and death. Fuel pump relay failure is the cause and very common, (100s of thousands of posts online about this problem). This problem affects these expedition vehicles in a widespread fashion similar to the lcm safety issue with another ford product, the crown victoria. (a recall was ordered on this issue for some of the model years) this has happened to me 8 times in 3 weeks since owning this 2004 vehicle. It is currently at the ford dealer who state they may need to keep the vehicle for up to 3 weeks to observe the failure mode. (it is intermittent)

I was pulling off from a stop sign and before I got across the intersection my car make a pop and then the engine sounded like it blew. I pulled over and a spark plug popped out of the head causing a small fire that melted hoses. Estimated damage is a minimum of 1500 for just this plug but I was told the others would follow suit. Reading on the internet this seems to be a serious issue with the ford 5.4 triton motors. If I was not able to stay calm and steer my vehicle correctly this could have resulted in a serious accident. The vehicle lost power as if it had stalled, and as I stated before there was a small fire when I lifted the hood to see what had happened.

Was driving down the road and my expedition just shut down. All power off and steering wheel locked up. Was stuck in middle of the road. Had it towed to ford dealership who replaced the main fuse. It happened again 6 months later. Once again had to have it towed. Once again main fuse blew and my SUV lost all power. Ford dealership gave us extra fuses. Since then it has happened twice, once about a month ago and we replaced the main fuse . The last time which was thursday, january 17th, my teenage son was driving and he ran off the road into a ditch. Wheel rim bent but he thankfully was just shook up and not injured.this time it was not the fuse but the SUV just lost power and steering locked and he went off the road. Missed a tree by a few feet. When this first began to happen I called ford and wrote them multiple letters. They were polite, but stated is was not their problem since car had 120,000 miles on it.

On two separate occasions, while driving my 2004 ford expedition, a spark plug has been ejected from the engine. One time, at city speeds, a second time at 65 miles per hour. Both times, there was an instant loss of power and the smell of gasoline filled the passenger compartment. After the original failure, I took it to an auto mechanic who replaced the spark plug and installed a replacement coil on plug assembly. I have not yet repaired the second incident as it occurred last night. It seems to me that this is a very dangerous condition that initially didn't seem that significant, but after the tow truck operator said, that he thought there was a recall, it prompted me to research further. His tow service operates in the harrisburg, pa area and he claimed that he sees this happen nearly 1-2x/week with ford 5.4l v8 engines. He said, that he's "seen so many of them, that they've got to have a recall.

Tl*the contact owns a 2004 ford expedition. While driving approximately 55 MPH, the engine lost power. The wiring harness was replaced; however, the failure continued a week later. On january 21, 2008, the dealer confirmed that one of the harnesses was defective and caused the engine to lose power. The dealer also confirmed that the failure was not related to a previous crash that occurred. The manufacturer in the corporate division stated that the contact would be required to pay $2,700 to replace the harness, but later adjusted the price to $780. The contact's claim number with the manufacturer was 1386151017. The contact does not feel that he should have to replace a defective part at his own expense. He asked if the part was defective, but no one has given him a response. The contact attempted to drive at reduced speeds to prevent the engine from shutting off while driving approximately 35 MPH. When he attempted to drive 55 MPH, the engine lost power. The contact was aware of the safety risk involved and was requesting specifics regarding his year, make, model vehicle and 4.6l engine. The dealer information was unavailable. The approximate current mileage was 66,000 and approximate failure mileage was 38,000.
