Great thread. I just reached 150K on my 2015. Thinking about replacing the water pump as a preventative measure. Car is running great. The EGR/cooler was cleaned at 91K and I installed an oil catch can. I empty it every 10K, and it is always less than half full, of mostly a liquid brown soot. No oil consumption at all, but then my engine has the improved pistons and rings. By the way, I saw a 2017 with 155K for $9K for sale nearby. More miles but a Gen IV. It's tempting, but I think I'll hang on to my 2015....
