2003 Mercury Mountaineer: stuck in gear or won't shift

Filed Jun 13, 2012 · Body, Electrical · FL

Ford has a tsb on their website for the problems I am having with my vehicle. I contacted tyem and I was told that I have to pay for the repairs. What I do not understand is if there are sooo many complaint from consumers on this vehicle for the same issues is that not the responsibility of the manufacture being it considered a defective product? I have to children and this is of extreme concern to me that these issues on my car can cause an accident. -back trunk door is cracked down the latch. -the car doesn't shift correctly and tires seem loose -the overdrive light is blinking all the time and the transmission is signaling.. I have found so many websites with complaints about the same issues on 2003-2004 mercury mountaineers.

The gear shift gets stuck in park and I have to pull down on it really hard to get it in drive or reverse I'm afraid that its going to break one day.

Purchased the 2003 mercury mountaineer in 2007. We only drive the car locally for school and work and within 30 days of purchase, the car would not go into reverse. Was told the transmission was slipping and made the dealership/warranty pay for $1600 repair. Since then the check engine light comes on every 3 months. We get check fuel cap message, replaced that twice (last one from actual ford dealership) because they told us it wasn't the original from the car. Car leaks water through the rear window/roof seal and now my light stays on when I lock the car and it tells me every time we get in the car that there is a door ajar no matter if we get out and reclose all 4 doors and back door. R&r wheel speed sensor and ball joints had to be replaced 8/29/08 for $555. Just recently had my transmission go out again (12/8/09) and had to have complete rebuild of a mercury transmission which cost us another $4000. It still slightly vibrates going between 30 and 40 miles per hour. Also the back hatch has cracked completely down through the logo. Our ford dealer charges $200 just to look at the vehicle!

I have a 2003 mercury mountaineer. I was stopped to get fuel. I put my SUV in park to get out. I was leaving my keys in it. When I stepped out and walked to the rear, my SUV started rolling backwards. I had to run back an jump in it and hit the brake. I looked at the gear shifter an it didn't go into park. It stopped in the middle of p and r. If I had locked the doors I would never been able to get inside before it hit the fuel pumps. It has been stopping at that spot every time I put it in park.
