1. Brakes wear uneven in the front. Rotors,pads,and calipers were replaced. Difficulty with bleeding brakes. 1 year later with 11,000 more miles on car the pad was worn and grinding rotor. Replaced both front rotors,caliper again. 2 techs had an extremely hard time bleeding the brakes for the peddle to rise. Car stopped but peddle went to floor. They worked on bleeding the brakes for 2 hours. They repeated the procedure 6 times. Bleed every wheel and pumped brakes over and over again. Could not get peddle up. This happened with the other brake job as well. Could not let my daughter drive the car. Took car home and the next day was on the way to another dealer when the brake peddle came up. 2. Daughter was in an accident before second brake job and hit a pick up truck in rear as stopping no one was injured and air bag did not deploy. 3. Have friend with 2005 Cobalt where her brakes completely locked up. Had to get vehicle towed and brakes replaced.
While driving to work, steering wheel had been shaking (55mph). Getting off the belt line, traffic came to a sudden stop. I braked, but the car continued to shake and didn't brake. Had to pull to the side to avoid hitting the car in front of me. Car would not accelerate when traffic started up, and I had to turn the ignition off and restart. Car shook badly for a few seconds, then seemed fine. A few days later, driving into my parking lot (10mph) the car's brakes locked up for no reason and I barely got it into a parking space. Took it in to the dealership the car was purchased at and was told the rotors, brakes, and calipers would need to be replaced. Had another mechanic look at it and had the brakes and rotors replaced. Car drove fine. Six weeks later, driving on the highway (60 mph), slowed down to turn onto another road, and brakes were out. Had another mechanic look at the car, brakes and rotors are worn down again, as well as calipers and brake line. Road conditions were clear at the time of each incident.
The vehicle has a recurring problem with the parking brake. The rear brake calipers lock up causing the parking brake to malfunction. The vehicle rolls away if not left in gear. The vehicle has experienced this problem three times over the past 15,000 miles.
