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!!!!.

When braking the vehicle accelerates, when slowing down to a stop sign or a red light and it happens when parking forward or reverse. I recently purchased the vehicle 8/2012. I am very dispointed because I really like this SUV. I hope the dealer will fix this speed control problem free of charge because this situation could get dangerous.
When coming to slow stop, the vehicle will lunge forward before completely stopping. This behavior started several months ago and was very random in the beginning, but has become more and more frequent - almost every time I come to complete stop. Vehicle also hesitates when gas is pressed and then surges forward. That behavior is very random at this stage, but car has done that over the past year. Because of the "lunging" at stops, I have taken vehicle to repair shop and they indicate the vehicle's computer needs to be updated. This appears to be a common problem with this make/model/year.
