- sun roof (won't close on one corner) - sun roof switch literally fell out of the socket while driving - power door locks randomly (and rapidly) lock and unlock, whether the car is on or not. It's fun to watch your car lock your keys inside right in front of you. - passenger seat heater button sucked into the dash after being pressed using a normal amount of force. - both seat heaters failed within a few weeks of each other, fuses and connections are good. - heater randomly loses temperature control and won't switch between any of the settings, the heater won't stop blowing hot air in your face, even with the ac on, and the coldest setting. - driver side door randomly won't engage from the inside or outside handle while unlocked, and if it is locked, the key does nothing. In a crash, it may make it impossible to exit the vehicle. - driver's side top corner windshield seal failed. Could lead to water in the electrical system, and fires. - cruise control won't reengage after braking. The fix for this is to push the cc button (turning it off) and pressing the brakes. It resets the cc, and will work again, until it fails later. - passenger side front mudflap came off backing (slowly) over an average-sized speed bump. Luckily, the front fasteners are integrated into the front bumper, so to replace the mudflap would require replacing the entire front bumper. - driver's and passenger's side rear wheel well skirt plastic fasteners have mostly fallen out, causing the foam filler to droop down and rub the tires, or fall out completely. - passenger side rear seat latch in the trunk (that releases the seat to fold down) broke off during normal use. - at highway speeds, the front end shakes violently (also on a completely random schedule) to the point that braking nearly causes the vehicle to go out of control. 2 visits to two different (GM certified) dealerships and all they could tell me was, "we can't reproduce the problem, and don't know what is wrong with it".

I purchased a 2005 Chevrolet Cobalt on 6-3-05 and after taking delivery began noticing the drivers seat moves ever so slightly back and forth in its track. This can be annoying at times. I brought the vehicle back to correct the problem only to be informed that it was working within GM specs and nothing could be done. I was also told that GM would be informed of this and if they get enough complaints to consider it a problem a fix might become available.
