I drive a 2009 Chevy Cobalt with a manual transmission. I am having trouble occasionally dying and not starting. I will be driving, stop my car, and take the key out of the ignition. As soon as I remove the key, the radio and clock shut off right away, instead of shutting off once I open a door. None of the lights on the dash are on either. When I put the key back in the ignition and try to start it, nothing happens. There are no noises, no lights on the dash (including the odometer), and no radio or clock. After waiting a bit (anywhere from 10 minutes to 30 minutes), I will get in and the mileage shows up on the dash and then the car starts with no problem. Once it restarts, though, the clock is reset to 12:00. Also, the average gas mileage is also reset.

I was having this problem a few months ago and took it in to the dealer before my warranty was up, but they couldn't find anything wrong. I had no more problems for a month or two, but now my car is acting up again. It's super frustrating, and I hate not knowing whether or not I'm going to be stuck somewhere.

First off, welcome and thanks for coming to us.

Have you verified that your battery terminals are clean and tight?

When we took it to the dealer, they told us that they had checked everything with the battery, including the terminals.

Trust, but verify :) If the dealer couldn't solve it, I probably wouldn't put a lot of stock in their assertions.

I'm trying to think through this logically. I would start by looking at the intermittent and total loss of power as a symptom and go from there. There may be a problem with the battery, ground, fuses or faulty connections (this last one sounds most probable).

If it were me, this is what I would do:
1. Check for stored trouble codes (most auto stores can do a basic check.)
2. Check the battery for proper voltage, clean terminals and proper connection.
3. Check both fuse blocks and examine your fuses for damage or corrosion. If you want to youtube it, check possible offending fuses with a multimeter for continuity. You can't always see if a fuse is bad by looking at it.
4. Check the battery negative cable to make sure it's grounded to the chasis.
5. Start looking at other grounds if all of the above fails.

Others, feel free to chime in. I'm not the electrical guru ;)

brittany713h did you ever get this figured out? My car has been doing the same exact thing once a week for the last 3 weeks. I checked the connections, terminals are clean, everything is tight. I took the battery out and had it tested and it is good. I have a 09 2.2 XFE. The battery is an ACDelco 90-6YR.
