Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

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.

The same as other complaints except it is an ongoing problem. Easy exit feature activates on its own, dome light comes on at slow or moderate speed, sudden stops and turning. Sometimes it corrects itself and sometimes you have to manually adjust the seat. Very annoying and unsafe

Seat moved back for "easy exit" all vehicle components shut off and vehicle brakes locked up in the road then cut back on by itself and transmission jerked into gear like someone rear ended us! very scary and unsafe with my 10 month old in the vehicle!

Mountaineer 8-cyl

  • 80,600 miles
Exact same as NHTSA id # 10654146. The "easy exit" feature activated at 65 mph in freeway traffic. I am 6' tall and was able to slide seat forward, but my wife is 5' tall and may have had issues reaching the pedals... this has since happened on 3 other occasions ( 2 at freeway speed, and once pulling into our driveway). I will contact dealer, but wanted search recalls first.

Mountaineer 6-cyl

  • 65,000 miles
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 Mountaineer as evidenced by the many reports on the internet. The cause is any slight bumping of the ignition switch or the steering column/wheel.

The contact owns a 2007 Mercury Mountaineer. The contact stated while driving various speeds the automatic driver's seat would move independently and the interior lights illuminated independently. This failure continued to occur for a month. The vehicle was not taken to a dealer for diagnostic testing. The manufacturer was not notified of the failure. The approximate failure mileage was 112,000.

Mountaineer 6-cyl

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 Mountaineer and Explorer. Tsb 09-22-15 came out about this issue. I was driving with my infant daughter and we could have been injured very badly. Something needs to be done about this. It has been identified and apparenlty affects people's cars and their ability to accelerate. Very dangerous.

  • 52,000 miles
The contact owns a 2007 Mercury Mountaineer. While driving approximately 40 mph, the front driver's side seat moved backward and forward independently. The vehicle was taken to the dealer for diagnostic testing. The technician was able to duplicate the failure and recommended replacing the ignition. The technician advised that if the failure continued, then the seating harness would have to be replaced. The contact had the technician disconnect the seat. The vehicle was not repaired. The approximate failure mileage was 52,000.

While driving at any speed the seat will go back to its parked position and the interior light comes on as if the car was shut off. You touch the key ignition and the seat goes back to driving position and the light goes out.
