CarComplaints.com Notes: The 2007 Cobalt inherited most of the problems from the 2005 and 2006 model years, but toned them down (a bit). Sure, the power steering still fails and the car has a chance of going up in flames due to a cracked fuel tank, but it’s not as prevalent as the older models. At least not yet.

In 2012, the Cobalt was recalled for gas tank fires but only for owners in certain states.

Then in 2014, the 2007 Cobalt was part of a massive GM recall due to a defective ignition switch that could cause the airbags to not deploy during an accident. The problem led to 13 deaths, government investigations and multiple class-action lawsuits.

This 2007 Chevy Cobalt has been nothing short of a lemon. Many problems which started very early in this car's life - most fixed under warranty but still a pain. Was unaware of the ignition recall, when the vehicle suddenly stopped while driving in Chicago. Could not restart so had it towed. Payed out of pocket the ignition repair. Shortly after that, at around 54,000 miles, the car stopped running. No engine lights or indicators ever came on. Towed to dealer and was found to have an engine failure. They claimed it was due to lack of oil, but this was not true. Somehow, the timing chain (plastic) had broken causing small pieces of plastic to clog the engine causing it to fail. NOTE: I am not a mechanic so forgive my layman's description. Bottom line, this new engine costs me $3,600. GM did pay half.

After new engine, the alternator went bad. Replaced at $600. Then, once again, the car would not run. Ignition would not turn. Car is at dealer again.

Question to all mechanical types: Could the ignition failure (car suddenly stops while driving) cause an engine failure?

Owners of this vehicle need to band together and form a class action suit to get replacement cars. This model is a death trap.
