I have had exactly the same problem -- both reflectors broke. There is clearly a design bug in this part. Would anyone like to take a guess on what BMW charges for this $.15 piece of plastic that fails? $40. Each. This is really absurd. I had doubts about buying a BMW because of the reputation of the company for over-charging for parts and service, as well as the standard porcupine/BMW jokes. But the i3 struck me as a real step into the future and the company seems to be trying to be environmentally responsible, something about which I care a great deal. But $40 for a 1"x2" piece of plastic that looks like it came out of a Cracker Jack box? I'm not paying for it, because the car is under warranty, but it still infuriates me.
