My truck stopped working in November 2025. I was told I needed fuel pump and filter. I replaced those and still didn't crank. I was then told I needed a circuit box. Purchased a circuit box and had it put on. Got my truck back February 2026. March 08,2026, truck went out again. I kept my truck maintenance and don't understand what's going on with it. I was told it is a recall on electrical parts and engine coils and spark plugs.

Defect investigations
Spark plug ejection from cylinder head
On september 6, 2005, odi received a petition requesting that the agency investigate allegations of engine spark plug ejection in certain model year 1997 through 2004 ford vehicles with triton v-8 and v-10 engines.odi received a total of 474 non-duplicative complaints on the subject vehicles where the complainant, or the dealer repairing the vehicle, reported that a spark plug detached from the cylinder and/or ejected from the engine.as of december 8, 2005, odi is not aware of any allegations where the alleged defect resulted in a loss of vehicle control, a crash, an injury, or a fatality in any of the 10,319,810 subject vehicles.in addition, odi is aware of only two incidents where the vehicle stalled without restart.information contained in the odi consumer complaints and obtained from 72 telephone interviews with complainants showed the following:(1) 99% of the complaints were on my 1997 to 2002 subject vehicles.(2) most the complainants reported hearing a loud pop while driving or upon starting up the vehicle followed by a loud, repetitive clicking or popping sound.(3) many of the complainants reported that the popping sound was accompanied by some loss of vehicle power; however, in 99% of the incidents reported, the vehicle did not stall.in the very few incidents where the vehicle did stall, most vehicles could be restarted.(4) only a small percentage of the complainants cited that they smelled gas or a slight burning smell when the incident occurred.(5) in all but a very few incidents, vehicle damage was limited to the engine.in one incident, the complaint reported that the fuel rail was damaged and replaced after one of the spark plugs ejected from the engine; however, the complainant reported that the damage did not result in any type of fuel leak or fire.in another incident, the only incident where a fire was alleged, the complainant reported that no fluid leak was observed, but that a fire resulted after the spark plug had ejected from the engine and he had restarted the vehicle and driven to another location.none of the complainants reported any damage to the vehicle hood.(6) only two complainants reported that they observed what appeared to be some drops of fuel coming from the cylinder where the spark plug had failed or on the spark plug itself; however, each of these complainants reported that there was no smoke or flames as a result of his incident.as the petitioner noted, and odi?s analysis showed, it is possible for a spark plug to detach from the engine cylinder threads in the subject vehicles.however, odi?s analysis of 474 complaints describing such incidents found only a very few alleged any safety-related consequences.none of these showed any evidence of a serious safety consequence.given the large population and relatively long exposure time of the subject vehicles, the complaint analysis indicates that the risk to motor vehicle safety from the alleged defect is very low.in view of the foregoing, it is unlikely that the federal safety agency would issue an order for the notification and remedy of the alleged defect at the conclusion of the investigation requested in the petition.therefore, in view of the need to allocate and prioritize the federal safety agency?s limited resources to best accomplish the agency?s safety mission, the petition is denied.

Fuel leaking from emissions vents on fuel tank. Non reparable part.
My Ford Expedition started randomly stalling and it stalled in the highway. The engine just shut down in the middle of the highway and it was such a scary a life endangering experience. This total loss of power in the middle of the highway when vehicles are traveling at highway speeds can cause death very, very easily to the occupants of the Ford Expeditions suffering this defect. I have been reading in many forums ( I have included the link to one of many forums) this is a common defect [XXX] ) many have Ford Expedition owners have experienced and have been very concerned and shocked that there was not recall. The issue is that the R303 relay (non serviceable fuel pump relay) fails very commonly on Ford Expeditions. In my Ford Expedition, the relay was melted. The fuel pump relay fails and cuts all current going to the fuel pump causing the engine to stall. This is a life-threatening risk caused by a defective fuse box with a defective fuel pump relay (R303). There were no warnings, the Ford Expedition just stalled randomly.

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....
Faulty fuse panel. This is a known issue. It is ALL over the internet. There has never been a recall. The vehicle will stall while driving. On attempting restart or crank, there is a buzzing noise from the fuse panel. The pcm #203 I believe, corrodes or melts through the board on the panel causing the fault. Replacing the fuse/relay will correct, but for a time. Panel replacement is required. First incident at 165k. Second incident at about 205k. After the last panel replacement, the vehicle continued to stall. Another faulty fuse, for the day running lamps, caused a fault, which melted the housing between the panel and the wiring harness. The screw attachment is "crunchy" because of the melted elements. The smell is noticeable, and the panel requires replacement again. Third incident about 246k. This is a fire hazard. The wiring harness is hot to the touch. Being a KNOWN issue, having discussed on various socials and with ford dealer techs, this should have been recalled ages ago.
