15 problems related to ignition have been reported for the 1999 Ford Expedition. The most recently reported issues are listed below.
Unusual circumstances such as window switch working the wipers, digital odometer going off and on, brakes working the interior dome lights,blower motor for heater coming on without a key even in the ignition,door locks don't engage until moving for a minute or two,after blower motor kicked on without a key, took to shop and they said water had gotten in the power dist. Box and floorboard had moisture also. Will cost me over 700. 00 but I cant afford to fix on my 600. 00 disability check I get a month. Thanks Ford!!!.
Water leaks in the windshield causing blower motor to stay on after ignition is on, randomly tries to start when key is not even in ignition, lights blink, could cause fire.
Unwanted electrical activity that can result in fires. Radio, wipers and hvac blower turn on spontaneously when vehicle ignition is off. Burning rubber smell sometimes.
Started my vehicle and heard a loud noise followed by a steady popping noise. I opened the hood and found the rear spark plug on the passenger side had been blown out of the engine. I have since read hundreds of other complaints of this occurring, some causing fires.
While driving a loud "pop" was heard followed by an exhaust-type sound emanating from engine compartment. Vehicle was driven 4 blocks to our home where inspection revealed the blown plug.
Spark plug (believe it was #4) blew out of the cylinder head. 66k miles. These were original plugs, so not attributable to faulty mechanic. Head re-threaded, new plug inserted.
While driving vehicle beeping noise like an alarm started to sound. Then the radio, the light saying the washer fluid and the 4x4 start flashing on and off when car is shifted into park it stops. Also on an occasion the heater was running the car was turned off key out of the ignition. Had to restart the car to get the heater to stop.
1999 Ford Expedition blew #3 sparg plug out of head.
The truck will not start, even though there is power. After waiting a few hours it starts up without a problem. It may run fine for a couple days and then have numerous problems for days on end. This has been going on for more than a month now. Called three dealerships and was forced to take it back to the original dealership (two hours away). The problem did not happen when at the dealership, was not logged on the computer and was charged $100. 00 to do nothing. I have heard from numerous people that this is a common problem with the alarm system (that does not log problems on the computer) that is under warranty. Have called Ford customer service and was told that there was nothing that they could do. After numerous times of lack of starting, the original dealership told me that we needed to leave the truck with them for an extended period of time (three to four days).
Interior lights malfunctioning, daytime running lights not working correctly, heating/cooling system not working properly; stays on even when key is not in ignition. When ignition is turned on or off, the woofer makes a loud thumping sound. Woofer inoperable. Right sign wing never worked properly/ will not open or close. Braking system is doubtful, it squeaks, and when gas is released engine and braking are not coordinated smoothly . Constant squeaking when in motion. Dealerships service repair personal neglect and refuse to find the causes, even though vehicle is still under warranty.
The engine starts normally after the key is turned but dies when I shift into gear. After the first failure, the truck was towed to the dealer who performed diagnostics. The tests did not show any abnormalities. I was told that they could not identify the faulty part therefore could not replace anything. They said it could just be a fluke and might never happen again. This was while the truck was under manufacturer's warranty. The second failure occured two days ago, approx. 6 months after the first incident. I was eventually able to get the vehicle started on my own and drove straight to the dealer. Again, they were unable to find any faulty parts. The vehicle is now out of manufacturer warrenty but is under an extended warranty. However, the repair shop said that they could not just start replacing parts without a clear cut diagnostic becasue the insurer would not pay. I am now afraid to drive the vehicle any distance from my home or office in case the defect stalls the car again or manifests itself in some other, more destructive way. I cancelled my trip for the fourth of July and am waiting on a dealer call back. I am assuming this is a glitch in a computer chip or something relatively minor, but difficult to find. However, the problem is a major one in my life as I do not feel safe driving this vehicle. The dealer has been responsive and is researching the problem. I do not know if they have access to a data base of other Expedition/f110 owners who may have had this same problem, so I am trying to distribute my information to a central organization that might be able to recognize a pattern of failure and identify it's cause. The vehicle has been maintained per the manufacturer's recommendations.
Had spark plug coil go out on #4 cylinder, shakes at higher speeds tires wear unevenly burning oil smell after you drive it had it to dealership 3 times and they "couldnt locate a leak " ( maybe there techs should read these TSB's?) finally reconized as bad head and gasket replaced still was leaking then I told I needed a total engine replacement! now its outta warrenty and my problem according to Ford dealership. Even though had it in for burning oil smell when under 36,000 (dot number: na tiresize: 275r16).
Failure of the #3/#4 coil packs seem commonplace on Ford Expeditions primarily due to the design of the heater hose (sits above the coil pack): if the hose drips, the result is a costly repair. . Read more...
Engine suddenly running very rough and engine check light on. Dealer investigation showed coolant leak on coil pack 4. Coil pack removed and replaced and hose clamp tightened. Repair was not done as a defect although many other vehicles have had the same problem.
Tire defect: driving under normal conditions with my family of five we heard a "bang" and realized the rear right tire had blown. Because of the severity of the blow out we felt immediately that this was a manufacturing defect and expressed our concern to nemer Ford. The Ford Expedition has never been used for any off-road purpose. Nemer Ford refused to do anything and simply referred us to the firestone dealer. We contacted our local firestone dealer and they told us it must have been punctured, which we knew was not true. We have not replaced the tire and still have the original tire to prove to someone that the tire is defective! firestone told us we needed to purchase another tire, I will not risk my family's safety by purchasing another firestone product. ( dot number: tire size: p265/70r ).
