Driving on a highway going 65 mph and the check engine light came on along with the traction light. The display says engine power reduced, service traction. I was nearly rear ended when this happen because my car automatically slowed down to 10 mph and stalled out and was barely able to get it over to the shoulder. I keep going to different mechanics and everyone says its something else and I have already sank over $1500 into this and yet it is still happening with no end in sight!!.
