1998 Ford Expedition Electrical system Problems

“The spark plug blew out for the second time in2 months. It sounded like the motor was knocking . Ford only put 3 threads in the cylinder head to hold the spark plug but the spark plugs have 10 threads. I called Ford and they acted like they never heard of this before. There are forums going back to 2002 that I was reading yesterday about this issue so clearly they were lying. Owners report engine fires when the plug blows out. My vehicle didn't catch fire .they refuse to fix this defect and deny its their fault.”

“Our 1998 Expedition only has 93,000 miles and it is posing electrical problems, the mechanic has told us it needs a new gem module. I have read at least 50 complaints about fords windshield leaking and causing same symptoms. Why would Ford do a recall. Or maybe they have. Can you tell me if they have. This could cause a fire which could cause a sever accident. All the complaints are very similar so it is a manufactured defect.”

“Went to store, came out battery dead, car wouldn't start. Had not left lights or any accessories on. Got a jump, drove to auto parts store. They checked alternator and battery and said battery dead, needed an overnight charge. Let them charge battery, put back in car, horn started blowing and would not stop despite my using both the key and key fob. Horn blew for 5 hours before I found out how to disconnect from google. Got horn to stop, and car wouldn't start. Ford dealer said anti-theft system had to be reprogrammed at cost of $250 plus tow to dealer. …”

“We have our Expedition for a while and we know the people who owned it before us. While it is raining and days after the power to the truck does not turn off. The radio will turn on, the blower for heat or air will keep blowing, the lights will turn on, the four wheel drive will stop, ABS will stop, and the wiper blades will not work. So because the electrical items will turn on at random, they drain the battery and the truck will not start the next day. We found out that due to manufacturing error, the windshield leaks water into the general electric module. …”

“My 1998 Ford Expedition blew out a sparkplug from the head while driving on the freeway. Repair costs exceeded $4000. In researching this problem I found not only were there other expeditions with the same problem, it seems that I paid aprox. Twice as much as other simialar repair jobs.”
