While driving today at a speed of 55 mph in somewhat heavy traffic my service traction control and stabilitrack indicator came on as well as a message on the dash saying the same. At which time my vehicle came to slow down and I lost power. I pulled over and and shut the car down and upon restart noticed that not only did white smoke come from my exhaust but the car had a rough idle the same indicators were still on and the engine light had now come on as well and was flashing. I was able to make it home with a rough limp however when I came to a stop felt as though the car was hesitant to keep running or take off. When applying gas there was a thump from the rear wheels like the transmission was not sure how to engage.
