2007 Mercury Mariner Owner Comments

problem #1

Dec 192011

Mariner 6-cyl

  • 84,735 miles


I purchased the vehicle with 6,000 miles on it. I kept up my normal maintance on the vehicle and replaced things when needed. At approximately 42,000 my transmission would no longer shift the gears. The vehicle was brought to wallace dealership of which they kept my vehicle for almost 2 weeks. They explained they did an overhaul of the transmission and fixed repairs on it so that their would be no further problems with transmission later on down the road. Now at 84,735 miles later, I am once again having transmission problems and my vehicle will not go into gear. Because I am out of warranty my vehicle will sit until I can make the repairs as a transmission replacement is not a cheap expense. This is a serious problem with in this car and deserves extreme priority of investigation on a recall for this year, make, and model of vehile. I am receiving no help from the Ford company and I am finding it extremely difficult that this problem in this vehilce has not been resolved or dealt with. I have had a private transmission company examine my vehilce (has not touched it), of which they discovered, the internal filter is clogging the cvt (constant velocity transmission) for which something will continiously break in the filter or where the filter is held causing this to happen. I was also advised there was nothing I could have done maintance wise or personal use of driving that could have caused this to happen.
