Spark plug blow out. Yes it is available for inspection. Ongoing very common issues with triton engines blowing out spark plugs making a fire hazard because fuel vapor coming out of plug hole could be ignited by coil pack. All ford dealerships are very aware of this issue and have repaired many by rethreading and installing a helicoil thread repair kit at a very high price of 800 dollars and most repairs are temporary because the aluminum is weak and very thin at the spark plug hole. Ford is very aware of this ongoing issue and denies any liability experts don't agree with fords arguments. No warning the plugs start to blow out at around 140000 miles well after the warranty. This problem started in the 90s all triton engines are affected. As in the photo the dealers attempt to repair was unsuccessful the spark plug is tightened to deep into the head and is broken off. …
The fuel module failed and the 5,4l Triton engine stopped running. There was no power steering or power brakes in the middle of the fast lane on the interstate. This was a safety critical walk home. The component was disposed of. The vehicle stopped in the fast lane. Possibility to be hit from behind, Ford denied my claim. There were no warnings of the failure. Galvanic corrosion.
Vehicle reports "check charging system" which has an associated TSB but no recall. My understanding is that the AC drips water on the alternator harness causing degradation and shorting of the wires. A new wiring harness as well as a drain relocation kit are required. I do not believe the customer should be responsible for this repair.
I have had several electrical failures on this vehicle after buying it new in October 2007, in October 2009 the cigarette lighter stopped working was repaired and again months later stopped working. The windows stopped working a total of six times with three of those being this year. I have taken my car in to be repaired a total of three times this year alone and the last time , about four or five weeks ago I instructed the worker to just let the windows up and disconnect them after being told that I needed a complete new wiring harness which were no longer available. I was told that the wiring was brittle and that this was a common problem with the f 150. I feel that this could pose a danger in an emergency escape situation as well as other problems. This problem also involve the electronic locking system which is a great safety hazard, I can get no real response from Ford.
I was driving down the road and I heard a loud popping noise so I pulled off on the side of the road and turned the truck off. I then saw smoke like the engine had overheated but in a matter of seconds flames ignited and I quickly got out of the vehicle and called 911. As I was speaking to the dispatcher there was a loud explosion and the whole front of my truck was engulfed in flames. By the time the fire department arrived and put out the fire my hood was totally burned up the engine is burned up and melted and the windshield and driver's side window blew out and the dash and front interior is burned and melted. I am lucky that I was able to get out in time because it happened so quickly. I am also glad my 10 month old son was not with me on this day.
Power windows stopped working entirely. At all switches. No power to them. Wires in door jam for power windows rubbed till they broke. Leaving no power to any window at any switch. Cost $ 370.00 for Ford to diagnose and fix broken wires right where mechanic knew they were broke before looking.. This is a recurring problem in these trucks and Ford should own up to it and fix them free of charge. I have always owned fords but after this episode with the dealership. Not to happy......checked internet. Many reports of this exactly as it happened and in same area of vehicle..have seen many complaints same problem, same fix, same place, similar costs to customer...not right. Ford is fully aware of this and doesn't care. Could have caused a fire. Had a burnt smell.
The engine was replaced in 2012 with 53,000 miles on the truck due to a significant knocking coming from the engine. The truck was still under warranty so it cost me nothing to replace. The engine started to make the same sound in feb 2015 (84,000 miles on the truck, 30,000 miles on the engine). I had it taken to an auto mech and they told me one of the spark plugs ejected from the engine and ripped all the threading out. They also found that on e of the cylinders broke off the crank shaft and ceased. The engine has to be replaced again and the truck is no longer under warranty. Both the original dealership that replaced the engine and the auto mech that I had the truck taken to, are researching if the parts are still under warranty.
Driving along, about 35mph, stopped vehicle at traffic light, engine started revving, placed both feet on brake, tried shifting to neutral, problem got worse (revved higher), light turned green, let go of brake, engine revved and vehicle went to 45mph without accelerating, applied brake, pulled over, shut off engine, restarted engine, still revving, pulled back on gas pedal with foot, engine rpms finally dropped to normal, inspected floor area -found no obstructions nor debris in pedal. Also concerned that this May have happened once before about 2 years ago, when I was involved in an accident.
Tl* the contact owns a 2007 Ford f-150. While driving approximately 15 MPH, the check engine warning indicator illuminated and the vehicle started to lose acceleration and power. The contact had to pull into a fuel station. The mechanic at the station determined that the ignition coil and a spark plug failed and needed to be changed. The vehicle was repaired. The failure recurred three other times and was repaired. The manufacturer was notified of the failure. The VIN was invalid. The approximate failure mileage was 116,000.
