What owners wrote

My stepbrother had two chevy cobalts. The first one he wrecked on a country road where he skidded on gravel, his car burst into flames. Fortunately, he was able to get out of the car. He replaced it with another cobalt. In january 2009 he had another wreck, single car. His car hit a pole and immediately broke out in flames. Unfortunately for my family he was not able to get out, he couldn't get his seat belt undone and the flames were melting the interior causing caustic flames.

At roughly 110,000 on a gently used 07 cobalt the internal timing chain broke and rendered the engine useless. The repair - a total motor swap for $5k! After I ran into this problem my wife looked up other reviews on the cobalt and found out numerous people have had this problem. This is a supper expensive error that chevy has overlooked and costly for the consumer - us!
