In case anyone cares. 2012 K1600 GTL 100,000 US Miles: Issues- 22k miles new engine under warranty due to faulty factory oil rings. The rings literally crumbled. Main drive shaft replaced at 65k miles-bought 2019 drive shaft off ebay for $300 and took me 4hrs to replace at home, Duel clutch micro switch replaced at 75k miles-I used Micro Cherry brand waterproof switches and soldered them in at about $5 for entire repair took me about 2hrs. I go through 2-3 sets of rear tires per year and one front, have my own Harbor freight tire machine and homemade balance machine at home, low beam headlight replaced at 75k miles. There is a great youtube that shows you how to change the lamp without tearing off any plastic. Took 1hr. TPMS I change batteries every 2 years now. There is a youtube on how to dig out the old BMW glue and change your own battery or better yet buy the Chinese TMPS and it is much easier to replace battery. You will need the GS911 and the TMPS wakeup tool. No other issues, very happy with the quality of BMW. If you want I can send actual part number for the repair parts. I buy my battery on ebay without acid so i keep one dry and ready at all times. Replaced my clutch DOT5 fluid with blueblood hope to get more life out of slave cylinder
