How is this not a warranty repair?
It is not normal and totally unacceptable for that to happen to such a new car.
It sounds to me like a crooked dealership. Is there another BWM dealership you can take it to? Have you called BMW USA?
Did anything ever happen with this?! It seems like there is enough around, every day I see one or two i3's buzzing around my area, Tatum and Shea.
I have an i3 with 20" wheels, I am looking for somebody local who is interested in a wheel swap, one of us would end up with four of the 5" wide...
