Again, check your warranty book to verify.
My own personal guess is that this is still an electrical issue, and maybe or maybe not a hard-part failure as well. Interested to hear how it turns out.
I don't have access to my warranty booklet/info, because its in the car which is at the dealer, but I did look at this webpage from the EPA, which explains what automakers must cover and the length of warranty etc, for emissions related parts:
The oxygen sensor is listed as an item that must be covered for at least 24-months/24,000 miles. It doesn't seem to be part of the required longer emissions warranty.
I'll certainly post again after I get the car back, and we see if the O2 sensor repair did the trick.
