Haha good finds. Although I have the 35i also, mine has similar issues. But I don't indulge in the types of fun as this kid.
you never told us about your bet against Wrangler. Who won?
Never did it, I don't want my rear bumper to broke off lol

Id say those are pretty accurate items that will break on all of them.
@jerrylin5168 had the same exact issues (expansion tank, thermostat) except the windows with my e70 2012. It is now in the garage for a valve cover gasket, hopefully that will fix the leak. Dealer initially told me it was the oil pan gasket for $2100, turned to a local BMW/Mini/Benz master tech, and told me it's the valve cover gasket $650.

My ongoing issue now is the transfer case. Vibration/shudders at low speeds and turning. It's been the problem with this model since I have the warranty, dealer kinda shuns it, insisted me to replace rotors, then wheels, did not resolve the issue up until the warranty expires. Reaches out to BMW US recall service and willing to cover half the cost, the dealer quoted me for 8000$, and it turned out the actual repair would cost is around 3000-3500$ so technically I still have to pay for it.

Still waiting for my tech if he can find me a rebuilt. Those new TC are really bad, unless they change/correct them, I see a lot of post and videos replacing the chain. I'm thinking maybe the front drive shaft recall was just a cover, the real issue is the TC.
This is an old thread, so you might start your own. You might clarify "BMW US recall service" and their involvement with the transfer case. There is no transfer case warranty extension of which I know.

I doubt that the entire transfer case is causing your issue, but think that it is a relatively inexpensive component; relative to $8000 or to $3000. Though procrastination may have allowed that part to have damaged the TC internals.
