Tbf German cars made in US have not been known for quality from what I recall reading over the years. At least people usually recommended avoiding certain models and going for other imported ones. Perhaps the US brands are less prone to failures because more parts or while models are made in Mexico/Canada and then just assembled in US.
Would be interesting if someone who knows more about specific models and parts could chime in.
JD Power: the most biased source I can think of for car awards.
