This is my second X5 G05, and this one is definitely of lower quality than the first. Removed bits here/there, replaced aluminium parts inside with coated plastic, replaced leather with synthetic-like thing and plenty of other cost cutting markers.
Don't tell me 'oh don't buy another one' as demonstrated by this article (and others), they all do it to pretty much the same degree, all you can hope is not to run out of warranty before something mind bogglingly expensive breaks.
I found it really sad to see that Mini (owned by BMW) and BMW are pushing hard on run-flats. Hard NOPE from me, as I drive a good amount in fairly rural areas, and driving 50mi from a random point (the flat-driving range spec of a run-flat tire) still leaves me at a random point with no service. And the quality is just gone way down, as you've noted. Too bad.
Lexus/Toyota being the most reliable.
Tesla is middle of the pack at #14 and some surprises (branding?) include Volvo at position 25.
