Fascinating!  That's the first time I've heard that explanation.  If true, what kind of software have they loaded into these vehicles such that resetting the oil life would kill OnStar.  For me they performed a software update which presumably could not be done over-the-air.  That just happened to be during an oil change - as was the case with another person here - ironically on the SAME day as mine just in a different city.
