“My 2008 Mercury Mountaineer is having a strong transmission kick when down shifting and a squicking noise which I think is coming from the break and my dealer kept on reporting back to me as unable to duplicate the problem. This SUV were bought as brand new and I feel like that the car is going to break apart or loose my break everytime I feel those rattles. Everytime I would go to my dealer for a service, I would always mention about the problem which they can't fix!”
