Having ESP coverage was the best part about this post I think, LOL. Heater core is rare to go, not sure I have heard of any other SHOs with that particular issue yet. Hope they put the dash back together right. If they replace it along with the evaporator (sold only as a unit at retail), then that will help the A/C last longer too. BONUS!
Which wheel bearing failed this time? Right front? I would have them check the tie rod ends & sway bar links while they have it in the shop.
What truck did you get for rental?
