I'm not sure I would say this is true anymore. At least with American cars since the early 2010's. The overcomplexity for no reason, the components that fail if use them is very common on every German car I've owned. BMW has had window regulator/motor issues, radiator overflow tank issues. Audi has had problems that if you use the glove box or center armrest the latches/sliders break. I just had to pull the navigation, climate controls shifter trim on my wife's A4 because the design of the ash tray (which has coin holders) makes it so coins slip into the lid track under regular braking.
American cars now have all the same tech, 4 wheel independent suspensions, and go 200k-300k miles without any more major issues then German cars. Many, offer AWD versions, and even with bigger engines get close to the same MPG (except big trucks/suvs).
I agree American cars of the 80's-90's were WAY behind, but since the early 2010's American cars are on par, and outlast the German counterparts.
Also, for us here in the US, American cars are cheaper than German, since Germans are Imports. Having grown up overseas, I understand that American cars are a premium because they are your Imports.
My current inventory: Audi A4 2.0T, BMW 325i, Ram 1500 Hemi
