Tl- the contact owns a 2002 Ford Explorer. The contact stated that while driving at various speeds the transmission would erroneously switch to 4 wheel drive and the engine would suddenly stall. The failure had occurred on several occasions. The vehicle was towed to an independent mechanic who diagnosed that the transfer casing and ignition coils were faulty and needed to be replaced. The ignition coil was replaced and the transfer casing was repaired but the failures continued to occur. The local dealer(unknown) and the manufacturer were notified of the failures but no assistance was offered. The failure mileage was 80000. Jft.

Due to a defect, we had to have the transmission replaced (thank god it was still under warranty). . . Then had to have the door ajar sensor fixed because alarm kept going off for no reason. About two years ago we were abut to go out of town for thanksgiving. I stop at a red light, and then we try to pull off when the light changes and hear the loudest popping noises. . . We're wondering how in the world did the spark plug pop out with so much force that it also rips the ignition coil. . . (fast forward to 1yr later, same thing happens while leaving home to go to work). Once again, on March 12, while on my way to work, sitting at a traffic light. Light turns green. . . I start to pull off and begin hearing a popping noise. . . Wth. . . Not again!!! (this is the third time this has happened in 2 years). Come on Ford. . . Fix the lemons!!!!.

I purchased a 2003 Ford Explorer in April of 03. When we took receipt of the vehicle the dome light was not functioning. The vehicle was repaired and we took over the vehicle. From about 6000 miles we had a problem with the vehicle stalling or not starting in cold or humid weather. We have had the car in for service to the dealership approximately 8-10 times a year for various problems. We have had the following concerns with the vehicle; the dome lights have been out, the rear driver window has gone out, the service engine light has come on numerous times, the light for the rear differential has come on several times, the power door locks have failed or locked and unlocked when driving the car at speeds above 40 mph. We have had problems with the vehicle stalling or not starting in cold temperatures or when it is humid or damp outside. They have reprogrammed the computer twice and replaced various sensors. The dealership also put a flight recorder on the car to try and determine what the sensors were doing at the time. On one occasion, while the auto was at the dealership, the car was in park, the car rolled backwards. We are still experiencing problems with the car starting hard or stalling or not starting and are frustrated that nothing seems to be able to be done for it. I have paid to have the vehicle hooked up to the machine and it is showing a problem with the fuel sensors now. The auto repair shop stated the ignition coils are rusty and should not be this way for the car having 60,000 miles on it. After the original 3 year warranty was up on the vehicle I told the dealership I wanted an additional warranty which the dealer supplied with no questions asked. I realize with it being an "intermittent problem" it may be hard to diagnose, but Ford has received their money for the product, I don't think it's too much to expect a "reliable" car. Thank you for your help with this matter.

The ignition coils were overheating and melting causing the vehicle to backfire and run rough. Father is writing in for daughter and is requesting assistance.
