So I leased a 2025 X7 40i about 9 months ago. Love the car, just with RTO I am probably going to be over miles a bit. I’m driving ~20k/year with a 36 month/15k lease term.
If I just prepay the additional miles now, does the powertrain warranty also extend? Or what happens in the edge case that the engine explodes at 50,001 miles right outside of warranty?
Any BMW-specific advice would be great. Thank you!
