Yes, I had this several times.

Cleared code and continued.

Finally had time and got an appointment, dealer could not find any history or issues related.

Had the steering recalibration done as well.

What did they do to recalibrate the steering? Is this for the shimmy?

Yes, but don't really think it did much

I had the exact something happen to me. My truck had 561 miles on it and after all the above messages showed it wouldn't start. Called GM roadside and had it towed to the dealer and it started and I drove it off the rollback. Mil light stayed on. Dealer couldn't duplicate the problem went over the engine and transmission wiring and didn't find anything. They called the factory and they said to replace the ECM and reprogram. They did this and no problems since.
