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.

THE CAR IS 8 YEARS OLD AND THE MUFFLER CAME APART IN THE MIDDLE THE EXHAUST. GETS SO HOT THAT IT SETS OFF MY CHECK ENGINE LIGHT AND IS RUINING MY O2 SENSOR. SO NOT ONLY DO I HAVE REPLACE THE WHOLE EXHAUST BUT THEN I HAVE TO BUY O-2 SENOR. THAT'S IF THE CAR DOESN'T CATCH ON FIRE BECAUSE THE PART THAT RIPPED APART IS UNDER THE ENGINE.
