My 2007 Mercury Mountaineer never had any problems until recently, thought it was the transmission because of the way it drove. Took it to the mechanic and got transmission fluid put in but the problems remained the same and was told the transmission was fine. My thermostat housing unit was leaking (this is very common with these cars and very dangerous, needs immediate attention!) and had caused very expensive wiring issues. Almost acts exactly like the transmission is going out - RPM's are way too high, the vehicle would not accelerate in the middle of city traffic, the car jumped at a stoplight and caused me to hit the car in front of me, and it doesn't shift properly. Problems occurred out of nowhere and are too dangerous to be ignored but very expensive to be fixed. Its very common and should be recalled before someone gets seriously injured!!!!
