We own a 2007 x3 and has been to the shop 7 times on top of the schedule maintenances.
We were stranded on a major Hwy IH35- and had SUV towed twice for engine overheating, waterpump replaced, thermostat on another trip, brake pads at 33k miles, engine leaking at 55k miles (paid $600 to replace engine gaskets) , Engine coils replaced, computer reprogrammed for idle problems,
door and roof seals letting air in (got very noisy) Buy one and you'll see what I'm talking about.
The dealer and BMW will tell you this is NORMAL FOR A BMW!! or just go by their shop before you buy and it will be full of cars being serviced, I guarantee it!!
