Just chiming in here- my ‘22 7 seat MX was delivered in late June. Just last week, after about 6 SC appts addressing several minor build quality issues, for the first time I don’t have a service appt scheduled. Issues included interior rattles, misaligned panels, marks in interior, missing seat back rivet and some more not worth mentioning.
I know this all sounds bad, but despite all the issues that needed addressing, the car is amazing and was well worth the wait (18 months for me). Everything was eventually fixed either at the service center or in my driveway. The car is awesome in just about every way. I had some older MX and S loaners during this process, and the interior design updates are leaps and bounds above the pre-refresh interiors, not to mention performance, handling, range, and efficiency.
On top of all that, the trade in value on my ‘18 M3 was more than I paid for it new (after tax credit and before sales tax)- that was a pleasant surprise for sure.
