Mine has been coming on for the last week. I don't tink this is normal, but my dealer says nothing is wrong. I also still have the surging issue, and they state nothing wrong. Even a small amount of coolnat loss is not normal, although I also have a 2014 Mercedes that does the same thing. So, with today's engines, is this the new normal? Topping off the fluid every so often?
