In owners' own words
Vehicle wouldn't start. Like the battery was dead, wouldn't even try to turn over.
While traveling at highway speeds (~65 MPH) the car has shut off 4 times. Each time car behaved the same way, as if the key had been removed: the engine stopped, instrument panel dials went to 0, lights turned off.
The vehicle shuts off while running. I've stopped at stop lights and when I try to continue driving the car will shut totally off while in drive.

Recalls for the 2005 Chevrolet Cobalt: 6
The weight on the key ring and/or road conditions or some other jarring event may cause the affected ignition switches to move out of the run position, turning off the engine and disabling the air bags. If the ignition switch moves from the run position to accessory, the car would stall and the air bags will not deploy in the event of a crash, increasing the risk of personal injury to the occupants.
In the affected vehicles, the key can be removed from the ignition when the ignition is not in the "Off" position. If the key can be removed from the ignition when the ignition is not in the "off" position, the vehicle could roll away: (a) for an automatic transmission, if the transmission is not in the "Park" position…
This defect can affect the safe operation of the airbag system. The key fob (if applicable), should also be removed from the key ring. In these models, the weight on the key ring and/or road conditions or some other jarring event may cause the ignition switch to move out of the run position, turning off the engine. If the key is not in the run position, the air bags may not deploy if the vehicle is involved in a crash, increasing the risk of injury.
The driver may experience a sudden loss of power steering assist that could occur at any time while driving. If power steering assist is lost, it would require greater driver effort at low vehicle speeds, increasing the risk of a crash.
Certain passenger vehicles not equipped with optional roof-mounted side impact air bags fail to comply with the requirements of federal motor vehicle safety standard no. 201, 'occupant protection in interior impact.' In a crash, head impact protection may be inadequate.
Certain passenger vehicles fail to comply with the requirements of federal motor vehicle safety standard no. 108, "Lamps, reflective devices, and associated equipment." The bulb shields inside of the headlamps can loosen due to vibration. The bulb shield can loosen or break because of vibration. If this occurred on a headlamp installed in a vehicle, oncoming drivers may notice additional glare, increasing the risk of a crash.
