2007 Mercury Mountaineer Electrical system Problems

“While driving my seat will randomly move back and forth as if I took the keys out. Thought something was wrong with my transmission but after having the garage put transmission fluid in it still feels like the transmission is messed up even though the garage says the transmission is fine.”

“I was driving home on a busy city street when I stop at a stop light to turn right. When I went to accelerate my Mercury Mountaineer when in to limp mode. As I inspected the SUV for problems I noticed the my engine/transmission wire harness was brittle and exposing bare wire and that the wires were touching each others cause them to short off the vehicle computer system and frying electrical components. It also caused the transmission to malfunction and shift wrong which in turn causing the torque converter to fail and destroy the transmission.”

“Driver's seat moved back, dome lights illuminated (vehicles easy exit feature) while driving at highway speeds. Luckily I am tall enough to reach the pedals and wheel while the seat was moved back, but my wife is only 5' 4 and would have a hard time reaching. This is a serious issue that has been happening to many other mountaineers as evidenced by the many reports on the internet. The cause is any slight bumping of the ignition switch or the steering column/wheel.”

“When driving the vehicle at any speed the seat moves all the way back and the interior lights come on. This also happens when you brake or go over a bump. This is very dangerous to someone of my size because when the seat goes all the way back I can no longer touch the pedals. This is happening very often and I have googled it and I can see that a lot of other people who own this year make and model are having the same problems with their vehicle. I have taken it to several mechanics and ford dealers and nobody seems to be able to figure out what is wrong with it.”

“Apparently there have been a lot of issues with the thermostat housing leaking fluid into the electrical system causing it to short out. I was driving, went to take off in rush hour traffic and they vehicle wouldn't go because the leak and ruined a part of the electrical system and the gears would shift. It was almost like the transmission had gone out. I have read several accounts where this has happened to tons of <09 mountaineers and explorers. Tsb 09-22-15 came out about this issue. I was driving with my infant daughter and we could have been injured very badly. …”
