Thanks. It's sitting lonely in the shop now, awaiting its fate, so hopefully they will be able to fix it. I wasn't too hopeful after the "I've never seen this happen before" reaction when I brought it in, but the head mechanic wasn't there; hopefully he can take care of it without too much trouble.
