| My wife was driving on the highway and out of the blue the stablity control and reduce engine power light came on the message display. there were no weather conditions at the time. this has happened 6 times total. one time it happened as she was warming up the car. all of a sudden it started shaking and she felt as if it was about to take off into space. she turned it off three times - even tried to drive it and move to another parking place and turned if off again before it finally stopped shaking. | |||
