I find that German cars have really dropped in quality. My dad changes car leases every 2 -3 years. Over the past decade, he's driven Lexus, Mercedes, BMW, Audi, Genesis. They were all brand new when he got them. He's only ever had problems with the German brands. His BMW crapped out twice, once on the highway and once while waiting at a light. My brother bought a BMW and he's constantly having to take it to the shop for repairs because something keeps dying. Over the past 5 years, my other friends that drive German cars usually always have issues. Meanwhile, my friends that drive Japanese or Korean brands seldom have to take them in aside for regular maintenance purposes.
Germans cars have never been particuarly reliable, that isn't the same as quality. The low reliability is mostly due to excessive complexity in the upmarket models they sell in the USA- too many features and exotic performance focused engines. The simple and reliable basic models from most of the german car companies aren't sold in the USA. It doesn't change the fact that the components, materials, and engineering are excellent, and they will last a lifetime if maintained well. The safety, performance, and driver experience are unparalleled.
That is utter bullshit. European brands are aside from Japanese ones the best at quality control. Even the oldest Volkswagen in my family is still in use, even it is over 30 years old. I mean there were some series of BMW that were bad, but those days are gone for good.
