Three problems related to battery have been reported for the 1999 Ford Expedition. The most recently reported issues are listed below.
The contact owns a 1999 Ford Expedition. The contact stated that she previously experienced failures with the battery losing power and the vehicle shutting off without warning. The battery was replaced three times, but the failure was not corrected. On may 16, 2009, while driving approximately 30 mph, the battery lost power and the windshield wiper washer released fluid. Within seconds, the vehicle shut off. The dealer stated that the gem module was corroded. The manufacturer filed report number 0481541389 and stated that there was no recall; therefore, they would not assist. The vehicle has not been repaired. The failure mileage was 80,000 and current mileage was 130,000.
Every time it rains. When SUV is parked and turned off the wipers come on. Headlamps and flashers go on and off. Radio turns on and off. Vehicle tries to start itself without key in the ignition. Battery discharges.
Every time it rains or snows, several functions controlled by my 1999 Ford Expedition's electrical system begin to function irratically. As an example, while driving in the rain, the windshield wipers do not function continuously. In addition, if the vehicle is sitting in the rain, several functions come on automatically and the battery inevitably dies. I've had to replace a battery and I would like for Ford to acknowledge and repair the problem before I sink anymore money into it. It appears that others have had the same problem and it has been linked to a leaky windshield and the gem module of the vehicle. A recall has been issued for explorers and mountaineers with this problem, but to date, nothing has been done about the Expedition.
