My parents were involved in a head on accident with a drunk driver who had cross the center line, in which case none of the airbags were deployed. The bunt force of the accident was to the passenger front corner of the vehicle where the passenger side of the uni-body and the front clip support cross section meet. The vehicle is being moved to the nearest mercury dealer.

My husband was driving a 2005 mercury montego on a highway at 55MPH when a jeep liberty crossed the median and impacted his car. It was a shearing impact, not a side impact. Our rear driver's side door and that quarter of the vehicle was ripped completely off. The rear driver's side door was bent over double with the liberty's license plate wedged in the middle.

I own a 2005 mercury montego FWD 6 speed. A couple months ago the transmission started jumping around, it seems like it would not go into to gear and when it does it will slam real hard. I bought the car used with 22000 miles and now it has 52000 miles. I've already replaced a motor mount because of the hard shifting. The dealership told me that it might be the valve body witch is around 2000 dollars with parts and labor. From what I have research about this car, it is a major issue and could get someone hurt.

Tl* the contact owns a 2005 mercury montego. While driving approximately 25 MPH, the vehicle began to decelerate independently with an increase in engine rpms to the maximum reading. The vehicle then began to shake abnormally. The vehicle was taken to the dealer where the technician advised that the brake pads, rotors and stabilizer link needed to be replaced. The vehicle was taken to an independent mechanic where the repairs were performed. After the repairs, the failure persisted.
