Filed Jul 30, 2015 · Acceleration, Engine · 165,000 miles · KY

My expedition started acting like it was starving for fuel misfiring loss of power and there's a ticking sound coning from under the dash board the door lock unlock the lights flicker and horn beeps by its self I parked it and a couple days later it wouldnt it trying to crank but its sound I dont believe battery is dead if it was then lights wouldn't come on now and again also when I use my key ring lock to lock the door there's a clunk cluck sound I've spent a lot of money trying to find out what's wrong with lamont that's my expeditions name and nobody knows last repair shop had it 9 days total on the 7th day I called them they said they had no idea and on the 9th I went in and they said I needed a new motor costing 2600 and charging me 220 to tell me that. The shop before that cost me 350 saying the truck itself were the plugs go in was stripped and they needed a special tool. Any how I believe it would be a matter of time before the vehicle will catch on fire. The vehicle is very unpredictable and you dont know what it will do next it also dies while driving it ..

This complaint is in reference to our 1999 ford expedition. My wife started out on her daily drive to work. As usual, she allowed the vehicle to warm up for 10 minutes before leaving. About 1 block from our home, she heard a pop and the vehicle started to shake, run rough, rattled and lose power. She also had trouble steering the vehicle because of the loss in power. She was able to return home without any further incident. I inspected the vehicle later in the day and found that the 2nd spark plug from the front of the engine on the passenger side had blown out of the head and damaged the coil. I am reporting this incident because I have read of many ford owners who have experienced this same failure. This vehicle received a tune-up at approximately 92000 mile in 2006. It currently has around 130000 miles.

Driving home from doctor visit, heard a loud pop, and lost power, very loud engine noise as if I had no exhaust. Mechanic looked at it apparently the engine blew out a spark plug making it necessary to replace the cylinder head since it stepped the treads. And also broke the coil. Am on disability and fixed income, the repair cost is so high I have to wait and be without a car. Do not know what to do. The mechanic told me it is a common problem with this vehicle and ford. And I researched the web and found out that many others experienced the same thing. Furthermore when going to ford for repair, they say that the new head is a improved version. So if it is an "improved" version that mean that they know that there is a problem with the product to begin with. Ford should replace the faulty heads at no cost to vehicle owner.

1999 ford expedition - blow spark plug out of number 3 cylinder. Result is loss of power and very poor drivability at low speeds. Also, gas smell from leading injector in now open cylinder. Fortunately I was not towing when the plug blew, or the loss of power could have resulted in an unsafe situation. Ford dealer recommends replacing the cyl. Head ($3,000), doesn't acknowledge any defect that ford has authorized. Several other mechanics indicate this is a common problem on this engine, deals with insufficient number of threads to hold the plug in the aluminum head.

Frankly, I need your advice on a matter of great concern I bought a 1999 ford expedition from waldorf ford in oct 2002. Recently I had a break down; I had three spark plugs blow-out, yesterday I was told that three cylinders are gone due from the damage of the spark plugs. The assistant team mgr said it would cost $6000.00 to get a new engine or get a new vehicle; I couldn't believe my ears. These trucks are lemons and I believe its time that ford take responsibility for their actions and recalls these engine. I guess they are waiting for someone to get killed. My truck lost power in the middle of rush hour and I was nearly rear ended. Other noted problems: the emergency brake cable stays on, the engine light stays on while driving and the brakes pads and shoes are worn out at a higher rate. *jb *bf

While I was driving on the expressway at expressway speeds all of a sudden there was a pop sound and the vehicle lost power and started vibrating badly. When got vehicle to mechanic by tow truck because vehicle had no power, it was revealed to me that the spark plug was blown out the head of the motor. It was the 3rd plug on the passenger side. My vehicle has a complete extended warranty but the warranty company claims that this is due to a loose spark plug. They are the original factory plugs supposedly you don't have to touch them for 100,000 miles. My mechanic states that this happened due to a defect in the head because he not only spoke to ford mechanics but has seen this before. This is a common problem, upon researching this myself I found many other people on the internet with this same problem,at the same exact site on the motor. This is a problem with the head of the motor and my warranty company should fix my truck because this is a covered item it is the engine block that malfunctioned , not the spark plug!!!! Please help because this is a very costly repair.
