What owners wrote
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.
We bought our mountaineer new in 2003. We have had numerous problems, but the worst has been with the transmission. We have consistently taken our vehicle to dealerships for service, but are continually told that they cannot "replicate the problem at this time". The transmission has always shifted hard, but dealerships simply tell us it just shifts hard. In january of 2006 the overdrive light was flashing and the check transmission light went on.
