The lady on the phone seemed rude and getting impatient when I mentioned the recall.

It's not a recall per se, but an advisory. Note that per the instructions, the dealer doesn't have to verify your complaint to replace it - your complaint should be sufficient. So they shouldn't give you any grief over that. But I'm sure they'll want to try and duplicate the issue just to make sure they don't give you back a still-broken car.

There's some anecdotal evidence from one member here that a bad ignition relay could also cause problems. It's a $10 part and very easy to change - cheap and easy enough that it would be my second choice before spending a lot of time in diagnosis beyond normal checkout.

And if the dealer does give you too much grief, there are other Chevy dealers. You're not duty bound to the one you bought it from.

It's not powertrain, but: "This special coverage covers the condition described above for a period of 10 years or 120,000 miles (193,000 km), whichever occurs first,"

Get your terminal replaced. Most likely all of your random issues will go away once you get that done. Right before i had to get my terminal replaced my dashboard lit up like a christmas tree and I lost all power steering in the middle of a turn.

When you say "terminal" are you talking about part of the cable or something else?

This only covers the battery cable replacement though right?

Correct. But let's get it fixed and see where it goes from there.

Note that intermittent problems are the worst kind for everyone involved. I say that as someone who has spent a lifetime fixing things. It's frustrating to the owner and it's frustrating to the tech assigned to fix it. Generally there's nothing to diagnose if the car's running properly. And since it only acts up occasionally, it will be hard to catch while it's having fits. About all the techs can do it inspect, take care of any issues discovered, follow any bulletins published (like this one) and give it back to you and say "bring it back if it happens again". I know that's not very reassuring, but that's the reality of repairing intermittents.

If you can find a pattern that will trigger it, it would be very helpful. But at the moment, we're suspecting something that will appear quite random.
