How many out there have cracks along the radious bends in the gas tank just below the the seat? Mine and a friends 2009 models were discovered cracked by a service tech at Ventura County BMW a few months back. Inspection of a new one on the showroom floor also revealed cracks. The tank crack discoveries were forwarded to BMW by this shop, but we have heard nothing back from either on a potential fix/replacement. The tank does not leak, yet....
