The contact owns a 2003 Ford Expedition. The contact stated while driving 45 MPH, the engine was misfiring, and the contact smelled a burning odor inside the vehicle. The check engine warning light was illuminated. The contact was able to drive to his residence. The contact stated that the failure had been reoccurring while driving. The vehicle was taken to an independent mechanic on five occasions where it was diagnosed that water was leaking into the ignition coil. The independent mechanic installed silicon around the boot to prevent water from leaking into the coils; however, the failure persisted. The dealer was notified of the failure and informed the contact it was not a known failure. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 196,000.

This vehicle has a faulty engine. The aluminum that Ford used to create the top end is too thin to support the pressure of the engine. As a result spark plugs explode from the engine at random with no warning. This has happened 5 times even after replacing all spark plugs, numerous coils and having kits installed by a mechanic sold by Ford to address the issue. $475 per kit from Ford. This is an enormous safety issue. The last one that blew out was on the highway with my two toddlers in the car.

This is the 2nd time it happened to my 2003 Ford Expedition. While driving heard a loud popping noise, followed by continuous popping loud popping noise like a broken exhaust muffler, sounded like a motorcycle. After investigating, found out that the #3 spark plug popped out (ejected) of the head cylinder, broke the spark ignition coil. When this happened, I smelled fuel, and saw smoke coming from under the hood, so I did not drive the car and towed the car home. I had to replace the ignition coil and spark plug and reinstalled the spark plug but it seemed to be still loose, so I took it out and put thread lock and reinstalled it but did not tighten it to the max and did not start the car till after 24 hours so the thread lock will hold it in place. Yesterday the same thing happened to #8 spark plug, it also broke the coil, and when I tried to install the new spark plug, found out that the threads on the head cylinder will not grab the spark plug, and now I am stuck without a car. When I asked around, people said this is a common problem on the Ford expedtion. This is dangerous and could kill someone if the engine caught on fire, because I smelled gas and smoke. If this is a common dangerous problem on the Ford expedtion, how come there is no recall for it"??? are we waiting for someone to die due to engine / vehicle fire to do something about it? please look into this issue asap and let Ford fix this dangerous problem. Spark plugs ejecting out like this" I noticed that there are only 4 threads on the head cylinder holding the park plug, but the spark plug has 10 or 11 threads and ofcourse only 4 of those threads are being held by the head cylinder. This is a dangerous problem waiting to hurt or kill someone, please ask Ford to fix this big problem, thank you....

Fuel pump relay shorted out in motion. Highway and city streets. Steering locks up engine just dies in motion. Super dangerous and scary replaced fuse box and same thing happened again. No power steering engine just dies in motion. So scary on highway 75 mph.

This has happened 3 times, first time stopped at a red light, when foot was put onto gas to go vehicle instantly lost power with no stuttering or stalling and had to put in park turn key over to go again. Second time, going 65 down the highway vehicle suddenly acted like it lost power and speed decreased, pulled over to side of highway and put in park and started right up. Third time, going 65 down highway started to act like it was losing power and showed dash lights as if all power was cut short and then gained all power back without having to pull over and restart.

Check engine light came on while driving home and the engine shut down 4 times each time the battery would die instantly. We had to keep jump starting it to get home. 2 days later the check engine light started flashing. Scanned it came back P0304 cylinder 5 misfire. Changed spark plugs and coils. Engine light went off.ran obd2 scanner to double check codes. Code P2503 charging system low voltage. Took battery to advanced auto parts had them test it. The coca should have been 650cca and was at 11cca so bought a new battery. Next day took son to school less the 2 miles ran fine on my way home it died 3 times this time I would wait a few minutes then restart it. Check engine light never came on started searching on line and and calling mechanics. So bought new alternator. Started the truck to warm up after 5 minutes it shut down again waited a minute and started back up did it again. This time the battery light came on. So after searching many people were saying the fuseable link was bad so went to Ford had one ordered installed it to day. Battery light still on started it ran for 5 min and died again. So now I bought new spark plugs, coil packs, battery, alternator, fusible lin. Now obdii code B1676- battery pack voltage out of range tester battery fully charged tested alternator it's at 14.7 which it supposed to be.

Engine suddenly failed while driving along a modest speed surface street while accelerating away from a traffic light. Suddenty there was a loud repeated poppling sound along with rough engine performance. I pulled over right away to a convenient spot. Initial inspection (have not had it towed or repaired yet, it just happened today) appears to be a plug blown out of the head. Apparently this is a common problem. This should be considered extremely dangerous because the open plug hole will allow explosive gas vapors into the engine compartment where the dislocated coil is still operating.

The contact owns a 2003 Ford Expedition. While driving approximately 35 mph, the contact heard a loud blast followed by smoke from the hood. The contact also perceived a fuel odor and the service engine indicator illuminated. The contact opened the hood and noticed a wire hanging at the back of the engine. The contact also stated that there was a small amount of oil on the side of the engine. The vehicle was towed to an independent mechanic who diagnosed that the spark plugs popped out of the engine. The technician remedied the engine head and replaced the spark plugs, but the failure recurred a couple of times. The manufacturer was made aware of the failure and stated that there was no recall. The vehicle was not fully repaired. The failure mileage was approximately 90,000.

Expedition 4WD 8-cyl

  • 157,000 miles
All 3 happened while driving on highways and in cold weather putting occupants at risk. #1, #3 and #7 spark plugs have blown out over a period of 15 months, destroying the coil in the process. All were the originally installed spark plugs from the Ford assembly plant. Reading and talking with other former and current mechanics, it is definitely a Ford design flaw and Ford should be held liable for repair/replacement, reimbursement and lifetime warranty or until the vehicle is junked.

We were waiting in line to go through santa's magical kingdom last weekend when one of the spark plugs shot off. Completely off. The coil pack was damaged and we were told it would need to be rethreaded.

The vehicle will randomly shut off at any speed, under any condition. Engine dies unexpectedly at highway speeds creating a panic to get out of the roadway. Power to steering and brakes are gone when the engine dies. Vehicle will restart after a couple minutes. The faulty part is the fuel pump relay. It is integral to the fuse box and cannot be changed without changing the entire fuse box. The fuse box is only available from a Ford dealer for $485.20 parts only.
