2009 Chevrolet Cobalt Owner Comments

problem #2

Dec 112010

Cobalt 4-cyl

  • Automatic transmission
  • 15,000 miles


The contact owns a 2009 Chevrolet Cobalt. The contact was stopped at a traffic light when she engaged the accelerator and the vehicle hesitated to accelerate. Later, while attempting to park in reverse, the vehicle would not move backward. The vehicle was taken to the dealer where they advised the contact that the transmission would need replacing. The dealer stated that the trans cooler line that connected to the radiator was not properly connected causing the transmission fluid to leak from a previous repair done at an unauthorized repair facility. The vehicle was not repaired. The approximate failure and current mileage was 15,000. Updated 02/10/11 the consumer stated the manufacturer agreed to fix the vehicle. Updated 03/14/11

I have a 2007 Chevy Cobalt and the power steering goes out when I go to make a sharp turn. (the wheel will not turn unless I give it gas and go straight for a little while, then sometimes it will then turn.) garage says that computer doesn't show anything wrong with it...but will take it back to garage again and again...until they tell me that a recall is on it. I pray that this doesn't happen when I'm in heavy traffic! very dangerous!
