my headlight has mousture in it is there anyway to repaire it without spending 2000 to replace it with a new one plse someone who has had this problem get bak to me thnx

LOVE everything about this car EXCEPT problems with wheels. In the 4 years we have owned it, we have replaced 9 wheels due to dents and cracking. We don't even know how this most recent wheel dented and cracked -- the dent is very small, but it is also cracked and now the tire won't hold air. These wheels are AWFUL!!!

Tires wear pretty fast..idrive takes some getting used too. BMW drives like a dream.

Brake recall - part on back order for months
constant tire problems - flats and cracked rims - this car does NOT like NYC driving - it is unforgiving
SNOW - take a bus or pray!
