Many reviews of this car featured a broken timing belt.
I have the same story, but it happened on the highway. Thankfully I was in the slow lane -- had I been in the fast lane I would have been killed. Standing on the side of a busy highway waiting for AAA is scary enough.
Needed a new belt and top part of the engine. Total repair $2500, but four visits to the repair shop later I decided to junk the car and got $2500 from a dealer using figures from autotrader.com. No harm, no foul and now I have a brand new Honda Fit and vow never, ever to buy a Chevrolet product again.
