My 2016 [late model SL] 3.5 has about 16K miles and the dealer is trying to sell me a brake fluid change. Sounds ridiculous to me. Any opinions out there?

yes that is very ridiculous, car is way to new for that. he would prob just empty the reservoir and refill. maybe at 40k you could do what i do and just siphon out the reservoir & pour in 12oz of fresh dot3 then repeat in a few weeks. this will gradually cycle in new fluid through osmosis. Dot3 is so cheap you can do it as much as like.
