| 2010 chevrolet cobalt ss. very loud brake squeal coming to a stop 20km and under (louder than a city bus). this has occurred consistently from 2500km. the car has been in the shop a dozen times, every time they machine the brakes and tell me the squeal is normal for high end brakes. i have driven porches, high end performance vehicles like sti's, 350z's, s2000's even high end bmw's, corvettes and ferraris, none of which have a normal squeal. | |||

| Driving a rented 2010 chevy cobalt lt, 4 door. had rented the vehicle from alamo rental cars on 7/2/11 the accident happened on 7/6/11. my wife and i were driving on i-4 east just outside orlando, fla. when the driver in front of me put on his brakes, i applied the brakes on the cobalt and immediately the car was violently out of control. the car going out of control was so violent i thought we had been hit from the rear. once the car went out of control i could not control it at all. we crossed all 3 lanes of freeway and hit the left rear tandem wheels of an 18 wheeler. the car finally came to a stop in the center lane facing in the opposite direction of traffic flow. just a few more inches toward the passenger compartment when contact was made with the 18 wheeler and this would have been a fatal accident. i have been beating myself up trying to figure out why just applying the brakes would cause such a violent and uncontrollable turn of events. then i started research on the web and found that brake issues with the cobalt is not a new issue. there is data on brake problems and individuals accounts of what happened to them when their cobalts went out of control just from applying the brakes. many of these accounts stated that dealers found no problems with the brakes following these instances of going out of control and in many cases being involved in accidents. this was the most horrific incident my wife and i have ever been involved in and the reality is that we were involved in this incident simply because i applied the brakes on the 2010 chevy cobalt rental. we were not hit from behind and there were no other vehicles involved with the exception of the 18 wheeler. | |||

| I purchased the vehicle in february 2010 and i didn't start noticing problems till around summer but they were not that bad till september were the car started showing strange electrical and steering issue. i received the recall letter in october and had the power steering issue fixed but its still have issues were the vehicle will swerve back and forth in return i will have to keep my hands on the steering wheel to try to keep it from hitting other vehicles on the highway. then the blower motor that blows the hot and cold air sometimes istatically revs up high and i have to turn of the heater. also i have noticed that the breaks squeal and i only have 10300 miles. i have also noticed that the needles on the gauges in the dash tend to twitch radically when i turn the vehicle off sometimes. then at times the car when turned on will start to act as if it was to shut off and the lights would all dim and then it would stabilize. it has done that on the highway making steering difficult at times. the engine as well had made knocking noises to its been an off and on thing. | |||
