The local BMW dealer keeps a jug of coolant as well as windshield washer fluid handy to top-up customer cars that casually drive in.

Agreed, 1-2 years. The M550 has commonly know coolant leaking issues where people get the add coolant message every few months or a few thousand miles. The dealer and manual will tell you this is normal consumption. They did it to me. Then the leak becomes greater and easily diagnosable and they replace old parts with updated parts. Happened to me, not one coolant low message since.
That’s all I’m saying. Push back on the dealer.
