Vehicle was recalled around 2010 for steering and fixed. Since then numerous electrical failures, power brakes, and steering failures have happened. Vehicle has been in dealer and numerous other shops over the years for same problems. Chevy dealer (kerry chevrolet in alexandria kentucky), where car was bought kept saying they did not know what was wrong. Even after hundreds of dollars spent to fix, problems eventually came back ( electrical failure, gauges fluttering, radio flashing, steering lock, power brake failure). This past weekend, gauges started fluttering, steering locked up while driving and car went into a spin running off the road. Chevrolet dealer has always passed all these things off as not their problem. I would like any info on what can be done about this. We are now afraid to have vehicle fixed again and drive it fearing steering may lock while driving at a faster speed. At least this power failure happened at a low speed and no one in the other lane during spin. Next time might not be so lucky. Please give us any info on what can be done. Thank you.

I drove my car about 1/2 mile to the local cvs. When I left I started the car and the brake pedal went all the way to the floor. I had lost pressure and did not have brakes. I have a manual transmissions. I pulled over in another parking lot and pumped the brakes to get pressure back. Car ran fine for a 15 miles. The same night I drove to another location and lost pressure of the brake pedal while sitting at a stop light. I pulled over and pumped the brakes again. I have driven the car since to the dealer and they cannot replicate the problem, nor diagnose it. They said it was intermittent and most likely the brake master cylinder. There was no evidence of brake fluid leaking from any of the brake lines or around the tires. The problem is they cannot say for sure if the master cylinder is leaking internally or if a gasket or seal is failing. I am going to have the master cylinder replaced and hope that is the problem, but I am afraid to drive on the freeway or at fast speeds because I have no cause for the brake failure. I am thankful I was not going fast, otherwise the only way to slow the car would be to down shift and use the emergency brake. This part is also not warrantied, but I am surprised it is already failing before I have changed the brake pads, rotors, or drums. It is weird. Now I have to wait for the part to come from the plant? They do not even have it in stock. Is this a common problem? I will be asking for the old part, but am unsure if I will be able to see if the master cylinder is bad.

This written complaint is in regards to the mechanical defect of an emergency parking brake within a 2007 chevrolet cobalt with a manual transmission. Events leading up to the incident were & remain as unnoticeable by driver and owner of vehicle. The driver had vehicle parked with the emergency parking brake in the up locked position prior to driving it. The vehicle was turned on and driven approximately two miles before being parked again. As driver of vehicle went to use emergency parking brake to park the vehicle, they immediately realized that the emergency parking break had no resistance when pulled upward and would not remain locked in the "up" position needed in order to safely park the vehicle. All other brakes within the vehicle remained as normal and functional. No other defects were detected by driver. The failure of the emergency parking brake failed to return to a normal status of function. The vehicle was taken by owner to local chevrolet dealership within 24 hours of incident on may 18, 2010 to be evaluated by dealership and be promptly fixed. The dealership's mechanics found that the emergency parking brake handle would not lock in place when pulled upward due to "the mechanism being stripped." the parking break handle was stated as being replaced and vehicle was returned to owner within 24 hours of being taken to dealership.

My 2007 cobalt has less then 24,000 miles. I was leaving the hairdresser and I went to press on the break to put the car in gear. My brake pedal went straight down. This continued on the way home. Took it to the dealer and they found nothing wrong with the breaks. But did find that the bushings on both side were gone. Dealer replaced the bushings. The next day I was driving home down a hill and the wheels were not turning. It seemed like I was losing power. I went to go up and hill and I had no power. Took it back to the dealer. They found nothing wrong. As I was leaving the brake pedal went to the floor again, back to the dealer. Still nothing. Only a week went by. The brake pedal went to the floor several times. I fear that I'm going to loose control of the car and hit someone. Back to the dealer yet again. Still this has not happened to them. They keep telling me my brakes are fine!!!!!
