Vehicle Shudder problems of the 2011 Mercury Milan

My car has shut off on me several times. The car will shake and then turn off. I can not start my car at will due to the defects. I have taken my car to get it looked at and no one can say what is wrong because it has to actively shut off and the wrench light needs to be visible when the run the test. So I took it to a dealer where I was told the throttle body needs to be replaced and it sounds like a power train issue. I wouldn't have bought this car if I knew it had these problems.

Traveling down the highway at 70mph car shuddered and lost acceleration and wrench light came on,got off on the shoulder, car was shuddering,turned it off waited a few minutes, turned the car back on and drove home with no problems. I thought it was a fluke,until today when traveling to work the car did the same thing, and again on the way home. It goes to the dealer tomorrow. . I don't need to tell you how dangerous this could be. I hope I make it to the dealer without an issue.

I made a left turn from a complete sign. In the middle of the intersection, the car decelerated and the wrench symbol on the dash came on. As I pulled over, the car started shaking and cut off. I had my children get out of the car because I was unsure of what was going on. I turned the car off, took the key from the ignition. I waited about 5 minutes and then restarted the car. I started and everything was ok. On 9/25/13, this happened while I was driving on a straight road. 9/28/13 - it happened while driving 65 mph on the interstate. 9/30/13 - after filling the car with gas, on a major road. 10/1/13 - just driving. 10/8 - making a left turn . There is not a warning before it happens.

I was driving around 70mph in rush hour traffic when all of a sudden my car started to shake a little and the wrench light came on. It went into limp mode and I was unable to accelerate at all. My car started dropping in speed dramatically. I pushed my gas pedal down all the way and there was nothing. The car was still running though. I couldn't get over because it was rush hour traffic. I ended up having to park my car in the fast lane as traffic flew past me. Very scary. The car rumbled while in park so I shut it off and restarted the vehicle. It came back on with no issue and the wrench light was gone. I looked it up when I got home and it looked like a bunch of people have had issues like this and it was their throttle body. I took my car into Ford and they said it was the throttle body and it needed replaced. Of course this wasn't covered under my cpo power train warranty. I got the whole thing done for $438. This part needs to be recalled ASAP.
