We had a 2009 Mks which accelerated by it self on April 21, 2014 and caused my wife to hit a tree and spend three days in the hospital and also totaled out our car. Not knowing that there was a problem with the car, we brought a 2010 Mks on May 7, 2010 and on May 8, 2014 when my wife pulled into our driveway, that car also had an unintended acceleration opposite causing it to surge at a high speed running through our garage door and the corner of our house. I then looked on the internet and discovered that there were several class action law suits in about 14 states dealing with the same problem, of unintended acceleration dealing with the electronic throttles causing this dangerous situation. To our surprise both of the cars we brought the 2009 and 2010 Mks was on this list for this scary and frightening problem. Now how you we get this defect corrected, so we can drive the car safely" is there an tsb repair bulletin sent to the dealers for this repair" please someone help.thanks

We have been having ongoing issues over the past 6 months, at least. The car has been in to the dealer 3 times for same thing. Some of the issues I have read regarding the F150 are the issues I am having with my 2010 Lincoln Mks. Driving highway, cruise will fall off, you feel it somewhat jerk off. Cruising later and it falls off again, then you cannot determine if it will continue running or die. It shutters, jerks, it seems to lose power. It seems to happen after about 20 minutes of highway driving. It is very intermittent, but has been more frequent lately. It does seem to stumble/misfire. Jerking around, not sure if it will die. The tack jumps considerable during these incidents. Concerns to take on longer journeys. There are times it is jerky and not certain if it will go or kill when I have also left a stop light. The last 2 incidents June 18th and the one on June 15th were very concerning, seems to be getting worse. We were unsure if we should continue on our way to appleton from fond du lac, about 40 minutes of highway driving as it was kind of twitching and dropping off the cruise, then the jerking as to if it could kill with the tachometer going to 5 and jumping back and forth. Something is just not right. I drive 25 minutes to work each day and it does happen on and off, hit and miss, nothing regular to it for how often.

I was pulling into my parking spot in front of my home, applying the brake, when the engine throttled up and the car bolted forward. Applying the brake even more did not stop the car. I swerved to keep from hitting my house and hit the post holding up the front porch. I applied both feet to the brake and the car came to a stop 10" from my house. It all happened in a matter of seconds.

I was driving 62 mph in cruise and decided I wanted to go 70 mph. I then proceeded to hold down the "set +" button until my speed reached 70 at which point I released the button. To my surprise the vehicle accelerated to 95 mph and held that speed. I then slowed the car with my brakes to 65 and again held the "set+" button until I reached 70mph. This time the vehicle accelerated to 80mph and held this speed.
