problem #2

Cobalt 4-cyl

  • Manual transmission
  • 24,420 miles
The check engine light came on so I took the vehicle straight to the dealership. They said it was a history code and not a big deal, so they reset it. After leaving the dealership it came back on so I went to a different dealership. They said the same thing and said they don't know why it is coming back on.

Cobalt 4-cyl

  • Automatic transmission
  • 4,300 miles
We purchased our 2005 Chevrolet Cobalt in mid December. In the middle of January we noticed that the air conditioner was not blowing cold air. Dealership replaced the air conditioner compression valve. Approximately one week later the vehicle began to display the "check engine" light and read "power less reduced" then, we began to have difficulty accelerating. The gas pedal became stiff. The dealearship replaced the air conditioner compression valve once again. Again the problem surfaced about a week later. The same part was replaced once again, and an appointment was made for the following Tuesday to drop the vehicle off for further investigation. Dealership discovered a faulty wiring harness causing the problem. We were then told that this was an engineering problem with the vehicle. Proceedings are underway to replace the vehicle with another car.
