Our 2016 (new) BMW has never had a major issue. Our 2014 (new) Volvo - which cost half what the BMW did, has almost never not had something going wrong with it. We bought a new Altima many years ago that was less expensive than the Volvo; we had it for several years and it was fine, but it was still in the shop more than this BMW (but less than the Volvo).
The issue isn’t so much reliability, but what it costs when there is a problem. Fixing the Altima would certainly be cheaper than the same repair of the BMW. The Volvo TCO is higher than the BMW or the Altima.
I also think you have to be comparing similar years. My sister - who’s 20 years younger than me - is still driving a 1996 Nissan 240SX, and it’s in great chat wasn’t a “cheap” car when it was new, but still. I think cars from last century were more robust.
