The car is at the dealer for another night. They were just going to wave the September 2014 technical service order that says the noise is "normal" when I exploded. The upshot is that they agreed to open a PUMA case on this again, but only after prolonged shouting and arm waving. The shop foreman claims he knows of a way around the sept 2014 orders ban on attempts to fix this and he asked for more time to try to get approval from BMWNA. Why they refuse to call any of the other western dealers who are replacing tires to find out how they are doing it they could not say. Anyway I drove the rental home for another night as they pretend to try to do something.
Honestly, it should not be so hard! The really funny thing is that the owner of this franchise is my neighbor: we are in the same HOA. Perhaps I should go knock on his door and ask him what the hell is going on? Or maybe call the six o'clock news and have them film me protesting with my car in front of his house?
The really sad thing is that the rental Ford Fusion is a better car than the i3 has been so far. At least it sure is a lot quieter! It steers better too.......
