What 2007 Mercury Montego owners say
Speed control & acceleration
Our 18 year old daughter who has a permit was driving our 2007 monetego one evening with me. When she went to park at a drive inn restaurant under my guidance, she was pulling into a parking space and the car unexpectedly lunged forward. As an inexperienced driver she panicked and took her foot off the brake - endangering the lives of at least 10 people that were eating at the picnic tables outside of the restaurant. Thankfully the car was going at a relatively low speed and the curb stopped its forward motion. I had noticed intermittent "lunging" when I applied the brakes just a few times before this and a clunking when shifting and I had already taken it to my local mechanic who checked the transmission and brakes but said they were fine. After the incident with my daughter we took the car to the dealer and they said that the throttle body is bad. …
I have experienced a sudden unexpected lunge when backing out of a parking space after placing the vehicle in reverse on several occasions. You can hear the engine RPM increase quickly, then decrease just as quickly when this happens. This typically occurs when the vehicle is placed in reverse and the wheel is being turned and the my foot is on the brake pedal. It has also occurred again when the vehicle is put into drive after going from reverse and the wheel is turned. Having the brake pedal depressed, is effective in stopping the vehicle, but since the timing and circumstances of the malfunction is unpredictable, it has become a noticeable and constant issue. I thought my vehicle was an isolated issue, but it appears to be more widespread. …
Transmission & drivetrain
I got my 2007 Mercury Montego premier from my mom, who I bought it from. At that time, there was only 52,000 miles on it. At 52,000 miles, whenever the car would be put in drive or reverse, it would lunge forward. Over the years, the problem has gotten worse and worse where now when putting green the car in drive or reverse, the car lunges forward to the point that I have no control of how far it will lunge. It's so bad that I worry that I might hit someone with my car just backing up. Now, at 130,000, the transmission appears to have gotten even worse where it is slipping in 2nd gear. You give the car gas and it seems to just be at a stand still, then a) of a sudden, the whole car just throws itself, and any passengers in the car, forward and just shakes the entire vehicle. …

An electronic device known as the Smart junction box has failed 3 times since new.the first two times it was replaced under the original manufacturer"s warranty. The warranty has expired and it failed again. This part is very expensive costing in excess of $500.00 plus labor charges which I must pay. When this part fails, the signal lights, brake stop lights and other devices do not work which are essential for safe operation. Vehicle reliability and security are in serious concern.
