 1. In shop currently, for acceleration failure (triple hesitation before going when you mash the gas)  2. Air conditioning repairs -- about 8 / 3 years.  3. Moonroof replacement -- dealership claims a child's kick entirely destroyed unit -- mighty fine workmanship, BMW.  4. My last BMW unless they figure out that customer service still pays, and its really more environmentally friendly to be 4X2 when 99.9% of X5 owners never leave the pavement (the 0.1% that do are back at the dealership within hours, no doubt).
