Thanks Tech II and Sarah. Today's it's working normally but I am overdue for the Maint II check-up and software update so I think I'll make an appt and see what transpires.

That thing with the TPMS valve stem corroding from the inside out on a car that's barely 4 years old is nuts. I'm a GM-lifer ('64 Tempest was my first car) and my father was a Mr. Goodwrench at the local Buick/Pontiac dealer for 30 years, but that's a really poor engineering job of the type I'd expect from one of the other Detroit makers. NHTSA complaint filed on that one. Hope they're recalled before I have to shell out $93 each for the other three...
