When making a right turn onto a high-traffic, four-lane surface street, both rear lower control arms failed under acceleration. This failure caused the rear axle to twist, the rear differential to shift position, and for the drive shaft u-joints to bind. The result was an effective loss of power and an in inability to accelerate to match traffic flow. Several vehicles had to brake hard or swerve into the adjacent lane to avoid the obstruction my vehicle created.

Ford has recognized a loss-of-power problem with its expedition and f-150 models in the 2000-02 model years with the 5.4 l. Engine. Simply put, in ambient temperatures over 100 degrees f, the engine computer will alter timing (in a misguided attempt to reduce engine temperature) which radically reduces engine power. Ford has a purported "fix" under its tech bulletin no. 02-12-3, dated 06/24/02, authorizing reprogramming of the computer and installation of some body plugs. Problem is that the problem remains after the tech bulletin work is performed. On my 2000 expedition, I continue to experience power loss of roughly 30% in stop/go driving and the hot summer temperatures in the phoenix area. This poses an extreme risk in city traffic, such as when you attempt to clear an intersection or avoid an accident. I've had several close calls this summer, "post-fix", when temperatures hover around 100 degrees--I hit the gas, and barely move.

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.

Reported engine losing power to dealership while vehicle was under warranty on 2 prior occasions before vehicle shut down totally while in driving mode. Dealer's service department could not find a problem on those prior visits. With the complete power failure, the dealer's service department found that a fire had occurred in the electrical junction box, burning several wires that had to be replaced. Dealer insisted that this total shutdown had nothing to do with previous lost of power that I reported to them. I was fortunate not to be in a lot of traffic when my failure occurred, but the next person may not be so lucky.

Vehicle continues to exhibit same intermitent power loss for the past 13 months. Vehicle is becoming very dangerous, as loss of power requires compensation on drivers part to anticipate traffic flow. Traveling through south dakota bad lands (towing 25ft travel trailer), climbing out of valley, when vehicle lost power. Vehicle was climbing out with no problem, when half way up the vehicle decelerated from 35mph to less than 5mph (no change in hill grade). Vehicle quit running approximately 100 miles from rapid city sd. Catalytic converters were burned-up. All dealers visited over the last 13 months have not been able to define the problem. Vehicle continues to self destruct.

Owned the car for ten months. During this period, the vehicle repeatly looses power without notice. Lately this has become a safety problem. While driving south on I-75 and the intersection I-475 (hauling travel trailer) the truck lost power up a slight incline. Truck downshifted 2 gears and engine shot to 4500rpm, while the speed dropped from 65 to 40mph in less than 100 yards. 18 wheelers swerved to avoid hitting us from the rear of the car. In the past ten months the car also exhibits other anomolies, such as seats and mirrors move and loose their position without command from the remotes. Once this happens, computer must be reset. Other anomolies that happen in conjunction with the mirrors and seats are the reverse sensors fail to work properly, and the alarm activates. Vehicle has been turned over to the dealer no less than 8 times without success in finding the problem.... Help.

I am concerned with the faulty mechanics on this vehicle. I have had this problem happen twice now since owning this vehicle. On jan 27-2001, I was coming off the 5 fwy and lost all power of brakes. I had to downshift to 1st gear to get my vehicle to stop, almost causing a serious accident at beach blvd. 2nd time, I was traveling on the 91 fwy at approx 70 MPH when my vehicle started swerving and became very bumpy. I had to veer off the fwy in a state of shock and dangerous matter. When I stopped, my truck dropped in the front right area. I got out to look and saw that the wheel had come off and was leaning into the inside of my tire well. I am now afraid of driving this vehicle and reporting it to you so you can look into it. Please follow up with me as to your actions and as to what actions I need to do to take care of this matter. Third strike usually ends up in ***death*** I do not want to be part of statistics or want to hear of any others getting hurt because of this malfunction. Thank you dean aughenbaugh.
