Thanks for all the help! Investigation of the expansion tank revealed telltale deposits around the coolant level sensor. Since when I had the system flushed the shop put in a new cap because it was whistling, my guess is that this boosted the pressure just enough to get the marginal coolant sensor level O-ring to start leaking as well. Trip to the dealer for a new coolant level sensor and $8 later - all seems well again.
