Power door locks are defective. My Cobalt locks go up and down by themselves the switches or fob will work. By doing some research online hundreds of people seem to have this problem. It is defective and General Motors should issue a recall about this.

I went to shut off my car Saturday night, May 28th and was unable to remove key had to remove battery cable to shut car off. Dealer familiar with problem. Apparently at least 200$ solution. This has happened to other folks also.

The battery continues to die and it causes the default factory alarm to lock the car. The keys are always getting stuck in the ignition. Right now im locked out the vehicle. The extra key can't unlock the doors (cant override the alarm lock).

2009 Chevy Cobalt. Over past 6 months, on a couple of occasions: Ignition switch would not turn off. I had to select ign switch on/off several times before engine would switch off and I could remove key. Sept 21 parked at hotel to check in. Returned to car- started normally. I parked car at room ignition switch would not turn off. Key jammed in ignition. I had to disconnect battery to shut off car. Upon return home car taken to dealer-ignition switch, collar and key removed/replaced. Dealer service mgr stated had several of these and mechanic familiar with replacement. I had a 2006 Chevy Cobalt that ign switch started to do same thing, but car was total loss accident before I could take to dealer. I think this is a fire/safety defect.
