I have a 2010 2.5S sedan with 36,400 miles. In the past 2 weeks I have noticed that when I start the car or when I start to accelerate from a stop that whiteish smoke comes out of the exhaust. I've read that it can be coolant mixing with the oil or oil leaking and getting burned. This seems extremely odd for such a new car. Any ideas or suggestions before I take it to the shop??
