Driving on highway when I was no longer able accelerate in my 2010 Mercury Milan. The car began to jerk and the throttle control/transmission light came on. I turned car off and on and then could drive a few more miles when it repeated the scenario above. I was able to drive it to dealership. It did that a total of 6 times on the way to dealership and eventually both the throttle control & the service engine soon light was on. Dealership fixed my car, replacing the throttle body but charged me saying the problem was not under any warranty.
