What owners say
At this point all 4 door locks/latches are messed up. Both driver &passenger back doors won't open from outside or inside. Driver &passenger front doors won't open from outside unless open from inside first. Key won't unlock doors. Back glass on hatch door won't open. Back wiper broken. Back hatch wouldn't open untill I paid to have it fixed. I contacted the manufacturer they said my truck not on recall list & wanted me to pay to fix it. My truck has same issues as the ones being recalled. How do they determine which ones to recall?
I purchased a used vehicle from redefined auto sales located in skokie, il on 3/11/17. Since then I have spent over $1500.00 in cost for repairs on this vehicle, beginning with I had to get the oil changed the same day that I bought the vehicle because the change oil required light came on as soon as I exited the expressway, I almost got into a serious accident on the expressway in route from the car dealership because a motorist tried to cut me off and that is when I discovered that the horn was not working. The next day the power door locks stopped working and things just has went down hill since then, the vehicle is in the shop right now as I'm typing this, I have not driven the vehicle anywhere other than back and forth to repair shops. I filed a complaint with the bbb but nothing was done about the complaint because the business responded saying the vehicle was used and I rejected the response and then received an email from the bbb saying that the case was closed. This vehicle was a lemon with a lot of issues and none of those issues were disclosed to me when I purchased the vehicle.
Rear door latch is inoperative. Also right front passenger door lock is inoperative.

The automatic locks do not work on all the doors. I've had these locks worked on, but they continue to not work. This is a safety issue, as the doors will not open at all. The driver's side rear door will not open when you try the auto-locks, and the lock cannot be manually pulled up, thus leaving the rear-seated occupant trapped in the car. This often times with the front passenger as well. It also happens with the rear hatch.
Have been having trouble with door locks, delay switch on rearview mirror, window lock and window functions, ABS on all the time ,door ajar light on all the time. Nonfunctioning dome light switches and intermittent check engine light ( which when checked was determined to be some unknown insufficient exhaust flow issue). Constant clicking noises coming from the far left drivers side of dash. We noticed a flame coming out of my left front top dash vent after car had been parked for 5+ hours. It's obvious the fire started in the dash and it burnt both of the wiring harnesses under the left front control panel hitting the vent line and coming out the top vent of the drivers side of the dash. We had to poor buckets of water inside dash vents/ openings and front hood area to get the flames out. Our injuries were incurred while trying to put out the fire.
1998 mercury mountaineer. The drivers door will not unlock from the outside with the key and most times will not open from the inside with the latch handle. I have heard that this problem exists with most 1998 - 2001 mercury mountaineers, ford explorers and ford rangers. In the event of an emergency such as a crash, I might not be able to get out of the vehicle.
Tl*the contact owns a 2002 mercury mountaineer. The driver's side door would not close. The failure began when the weather was cold and then occurred during hot temperatures. Currently, the failure is constant, which causes the door ajar warning light to remain illuminated. The interior dome light remains illuminated as well. No repairs have been made and the dealer has not been notified. The failure mileage was 80,000.
