I brought the car to the dealer after EML light and check engine light came on with rough running engine in "limp" mode. Car was towed; it is 3 months old.
The car worked normally at the dealer who also test drove it. I picked it up yesterday and had the same problem at highway speed after 50 miles. I was able to get home, and this morning, it runs fine again with no trouble lights on the dash.
I will bring it back to the dealer again. They said that they intend to change the engine control unit. I hope that this solves the problem.
Has anyone had a similar experience?
