Ignition Coils Failure Problems of Ford Expedition

After accelerating from a stop, a loud bang was heard. What had happened? a spark plug blew out of the aluminum head, taking the threads with it. I was not aware that fuel would continue to blow out of the spark plug hole which could have been ignited by the ignition coil or exhasut manifold. Ford is aware of this issue, but has not recalled the defective aluminum heads, but rather offered a repair kit to fix the stripped threads when this issue occurs. This could have been a very different ending if the fuel would have ignited.

My wife was driving with our infant son and our teenage daughter in our 2003 Expedition XLT 4. 6l 2x4. She heard a loud pop and the vehicle lost power and started smoking and shaking violently. She thought the Expedition was going to blow up. We had the Expedition checked out and the cylinder number 7 spark plug blew out. The aluminum threads in the head gave and the spark plug blew out, the injector kept spraying raw fuel and the coil ignited it. When all this happened it burned the ignition coil, coil boot, spark plug and the coil harness. Now we were told we would have to have the cylinder head replaced. We love our Expedition and I considered buying a new one, but I don't know now.

The contact owns a 2003 Ford Expedition. While driving 70 mph, the entire vehicle began to jerk and ride roughly. The contact stated that the service engine light illuminated. She pulled over and turned off the vehicle. She restarted the vehicle and drove to the Ford dealer. The dealer performed an ids diagnostic and pinpoint test and discovered that a cylinder misfired on cylinder number 4. The dealer replaced the ignition coil and spark plug assembly. The current mileage was 74,800 and failure mileage was 74,776.

On 7/3/2007 I heard a loud banging sound and smelled gas coming from under my engine. When I had it towed to sioux falls Ford, they said a spark plug had blown out. When I asked if that was a factory defect, I was told that the plug may have been put in incorrectly. I have never had the spark plugs replaced, so I knew it was a factory plug, but the technician said that they had no way of knowing that. I spent $800 to have the it re-thread. 4 weeks later, a different spark plug did the same thing. At that time, they told me that they would check all of the spark plugs to ensure that they were tight. 4 weeks after that, the ignition coil needed to be replaced in that plug and the plug needed to be replaced. They claimed that their repairs had not caused this, but I feel like I have been getting the run-around on all of this simply because I am a woman.

Vehicle underwent normal driving. 2. Suddenly upon starting the vehicle a loud popping noise from the engine compartment was heard. There was loss of power, and would continue whenever the engine started. The odor of gasoline and oil was emitted into the vehicle. The vehicle had to be immediately brought into a Ford dealership. Instead of replacing the entire head as required by Ford , helicoil, spark plug, and ignition coil had to be installed by the dealership.

My 1999 Ford Expedition has had to have the ignition coil packs replaced at least 4 times. The symptoms are misfire and a resulting severe engine vibration upon acceleration. Once the vehicle reaches a cruising speed, the problem appears to go away, but only until you accelerate again. Ford motor company knows there is is design flaw in these vehicles which causes water dripping from some source (the air conditioner or a windshield that is not sealed) to short out the ignition coil packs. They have a technical service bulletin out on the problem, but the problem is not always reported as a check engine light and they fail to diagnose this properly in some cases. The first 2 times this happened, I took the car to two different Ford dealerships. Both trips cost me close to $400 each time. The third time it happened, we went to our local garage and the guy said this was a common problem, well known to auto mechanics, but that the individual failing cylinder could not be readily diagnosed by the computer codes, so it was an expensive repair because they might have to try all 8 coil packs to locate and identify the offender. The last coil pack that failed was replaced by my husband at a cost of $45. 00 as the failing unit was easily accessible. You can see the great difference in cost of doing it yourself vs. Both of my trips to the dealership. My truck is failing again now and of course, it is exhibiting the same symptoms of a coil pack failure. This time, however, the coil pack in question is not easily accessible for the home mechanic and we will be forced to take it in for repair.

2001 Ford Expedition ignition coils continue to short out when wet and always after a rain - water seeps into the engine compartment and inevitably that an ignition coil will begin to short out / begin missing and lose power while driving. Because this always seems to happen during inclement weather the danger factor is heightened. I have spoken to other 2001 Expedition owners and they all have experienced the exact same dangerous and expensive problem. Another issue of consumer concern is that Ford motor CO. And it's service representatives are keenly aware of this and in fact have repaired the continuous problem during the first 75,000 miles. I personally have had the coils go out on me while driving in dangerous weather and have now had five(5) ignition coils go out on me at this time. Ford motor CO needs to take responsibility for this inherent mechanical problem and finally correct this problem before any accidents and deaths occur.

Ignition coiled burned out causing a 30 amp fuse to fail. The car immediately stalled and would not start again due to electronic system shutdown. The car has only 40,000 miles and it and has had all recommended service. The Ford dealership service department who made the repair stated that there were 8 of these ignition coils and they could burn out at any time causing the same failure.

2000 Ford expedtion 4. 6, ignition coils failing, dangerous to drive. Ford knows it is a design problem, Ford dealers not warranteeing or replacing the part.

Tire tread separated. (nar) while driving a piece of the passenger side rear tire tread came off the tire. The tire was replaced with the spare. Next the drivers side rear tire tread separated which caused temporary loss of control. The tire damaged the rear bumper and wheel well. While doing research the consumer came across a recall notice for the tires. The consumer request reimbursement for the price of five new tires, damage and mental anguish. The vehicle transmission also had to be overhauled because it caused the vehicle to vibrate while changing gears. The ignition coil was replaced to alleviate bucking while driving at a steady speed.

The ignition coil failed twice which resulted in a sudden loss of power while driving 70 mph. The vehicle was taken to a mechanic who determined that the ignition coil springs were defective.

On 5-03-03 ignition coil for #7 cylinder failed. I was told that it is unusual to occur on a vehicle with 56,000 miles. On 10-06-03 ignition coil for #6 cylinder failed. I was told that this is highly unusual that this occurs on a vehicle with 63,000 miles. On 10-14-03, I contacted Ford requesting an inspection of this unusual occurrence to prevent any further failure of the ignition coils and was told that they could not help me because I repaired the condition.

The #4 ignition coil pack failed and was replaced. This is a common problem on Ford 4. 6l and 5. 4l engines. I am creating a database of failures from multiple user groups and can confirm multiple (up to five on the same vehicle) failures of this part because of a heater hose that leaks on to the coil pack directly beneath it. Mine failed while accelerating on to a highway, and was almost rear-ended since the truck suddenly lost power being that the #4 cylinder was no longer firing. Since multiple failures have been recorded, Ford should be liable for this as it is clearly a design flaw.
