While driving from work the car did a quick jerk and the STABILITRAK, ABS AND CHECK ENGINE LIGHT ALL CAME ON ALL AT ONCE. As I pulled into my workplace the car lost power to the engine completely while displaying ACTION REQUIRED ON THE LCD SCREEN. The brake and steering wheel became stiff and it was hard to control the vehicle. It took 10 minutes for me to regain power and control over the vehicle that again after leaving work stopped on the highway.

Stabilitrack and engine light came on at the same time with a message that said, 'engine power is reduced'. This occurred as I was driving on the highway. The vehicle gradually slowed, but I was able to maintain a speed of 55 MPH. I was unable to accelerate quickly.
