started losing power ,did not want to go pas 30 miles per hr ,then it ramed up and came to a stop with no acceleration ,i shut it off then start it again and was able to get home at a low rate of speed while continuing to have these problems, another day while far away from home the engine rammed up again minimizing my speed as the transmission was slipping and not go fast then my O/D over drive went on flashing a light ,while the engine kept steady at 20-30 miles per hour while accelerating increasing no speed ,now my SUV will not run wright, it will kick into gear at times constantly and cause problems driving safely ,this is a common problem I'm hearing and reading in the internet with the ford/ mercury mountaineer the manufactory does not want to accept responsibility with this problem ..... this is clear a RECALL ISSUE that needs to be addressed before someone gets killed on the highway by getting rammed by a semi-truck which it almost happened to me !!!! a multi-million dollar law suit is in order if they do not acknowledge and fix this problem

Whenever I drive in town or highway, I have been having issues with the power train/transmission. It is constantly slipping and shift hard. I found out there was a recall on my exact year, make, and model. I called ford about the same exact issue I have as described by their site. But my VIN# doesn't show up as one of their recalls. Which doesn't make sense. So now I have to pay thousands of dollars out of pocket since they don't want to take into consideration that my vehicle is having the same exact issues as the other SUV.

The transmission is slipping between gears, revving way higher than normal to shift and won't go into overdrive. My research of the problem shows this is a common issue on ford and mercury vehicles in this year range.

Tl* the contact owns a 2007 mercury mountaineer. The contact was driving approximately 50 MPH when a vibration was felt and the transmission began to slip gears. The failure appeared to occur more frequently in warm weather temperatures. The vehicle was taken to an authorized dealer but the technician was unable to duplicate the problem. In addition, the instrument panel and gauges would illuminate intermittently as a result of defective pixels. The front driver's side power seat would move backward and forward freely while the vehicle was in motion. The contact would shut off the vehicle and once restarted, the failures would correct independently until later recurring without warning. In addition, the headlights failed intermittently. The vehicle was not diagnosed or repaired for the failures. The manufacturer was notified of the defects. The approximate failure mileage was 46,000.

2004 mercury mountaineer v8, 47,000 miles. Transmission is shot. It slipped in and out or reverse (creating a very dangerous situation since I could not control the vehicle when it was in reverse) and it struggled to shift gears in drive. No warning light before the problems began. The vehicle aged out of warranty in july 2010. Ford will not pay for anything (although the dealer is cutting me a break on the service costs).

Purchased 2002 mercury mountaineer from ford dealership in 2007. Transmission was slipping, took in two days later and still under warranty and informed new transmission put in. In august 2010, vehicle suddenly would not start, towed to dealership and informed the transmission was once again defective and sensors as well as cpu unit would need to be replaced. Researched on line on www.autobeef.com and noted many other defects on similar make, model and years with very similar problems. Approximate cost to fix $2,400 dollars.

Transmission lever binds when attempting to shift into park, slipping into reverse instead. Problem has occurred sporadically from 2007 to date. Usually the miss-shift is noticed because it just doesn't feel right, but not always. It can be most dangerous if you don't turn off the engine immediately (after attempting to shift into park) and take your foot off the brake. That has happened to me about 5 times over 5 years. It happened twice at a gas station, once at a car wash, once in a shopping center, and once in front of my house as a child walked behind the car. In each case the car only moved 1 or 2 feet before I realized it, and was able to step on the brake. These days I don't need to worry about it as much because (at 52,000 miles) the transmission takes 5 - 10 seconds to engage the reverse gear and then it bangs into gear, loudly alerting me that it didn't go into park.. The transmission is defective, and ford knows it.

I have a 2002 mercury mountaineer, I have had more problems on this car than are countable. The transmission has slowly been slipping since I bought the vehicle. I have had to replace the transfer case within the past two months, and now my check transmission light and od off light is on. Mechanics now say I need a new transmission. I have looked at numerous review on this make and model cars and all have transmission problems, and those who said they replaced the transmission, the problem recurred and it was a waste of money. I am just trying to figure out what to do these prices is getting very costly for a car that seems like cannot be repaired.

The transmission keeps slipping causing the car to stall and stutter in traffic had to have it rebuilt in 2008 costing $3600.00, the differentials causing problems on front and rear with the car wheels spinning and sticking at times, the tires (all four) balling out from the inside out having to replace them every three to four months, the power locks, radio, interior lights all work when they want to like its a shortage.
