FYI, it looks like NHTSA has now got a couple of copies of your complaint in the public database. Congrats, yours is the first complaint for a 2010 X5. Perhaps more will follow (I suspect most people don't know how to make a complaint, even though it is in the firs few pages of every vehicle Owner's Manual).

It's really too bad, as if more people made these complaints, systemic problems would probably be discovered sooner by NHTSA. But for people with problems, please note, NHTSA is only interest in problems that are a potential safety hazard, e.g., if your stereo isn't working, or the dash is creaking, or there's cosmetic issues, don't waste your time as NHTSA doesn't care.
