Again, the car steadfastly refuses to be broken. I guess you can’t expect a mechanic to diagnose a problem if he or she can’t find it. I will, of course, be very upset if this problem persists or gets worse. (So far I haven’t been stranded anywhere, just given a few panicked minutes when I thought I would be.) At least the dealership didn’t charge me for anything, and it was almost fun taking the bus again after so long. Almost.
