The battery on our 2006 Cobalt goes dead for no apparent reason. This is happening more and more often.

Does it click or try to crank when you turn the key? If nothing happens it could be a faulty safety switch (clutch or park on an automatic) or the ECM (electronic control module)

replace ignition switch.

Is the battery dead? Check your battery condition and connections. Check your starter fuse from there. Check the connection to the starter then progress to the ignition side of the concern

sounds like ignition key cylinder is bad have to get a new one from dealer with vin

Your ignition switch is stuck. Listen, go back to your car and try moving the steering wheel left and right, back and forth. As you are doing this, try to get your key unlocked from the switch. Sometimes you can get them out this way. Otherwise, you might have to take it out the hard way. Try it and write me back. Let me know if it works. If not, I can guide you through the steps.

take off front tire

It sounds like the power steering motor is overheating pre maturely. Changing the motor should take care of the problem. What really happens is the motor reports to the power steering module that it is over heating and the module is shutting power to the motor down, the motor is actually no overheating.

jumper cables

The main problem could be a well known cobalt ignition issue. check all fuses, wires, and connections if you've worked on cars before and call to see if you still have any warranty left. This should be handled by a chevy dealer or chevy trained mechanic...to isolate the issue fast and avoid repeat visits to get er done.
