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.

2007 Chevrolet Cobalt Owner Comments

problem #1

Oct 022013


  • Automatic transmission
  • 78,000 miles


My daughter purchased the car used, from a dealership with her savings so she would have a dependable car for college. The car ran absolutely fine up until the day she started losing engine power. Within a couple miles the car stopped completely. We had it towed to a mechanic we trust. Right now the report is probably blown out valves since there isn't any engine compression. I have never had a car engine go at this low of mileage. I have taken her car in for oil changes and service. It was a well maintained vehicle that should have lasted for many years.

Update from Oct 29, 2013: The timing chain broke and destroyed the engine. I had the engine replaced. The mechanic showed us the extensive damage. This engine is in many vehicles other than the Cobalt and is supposedly dependable. I have never had an engine replaced at 78,000.
