Oh please, American cars technologically are no different than any other cars these days.
On average, that's false.
The main problem with American cars these days is styling.
No, the main problem with American cars these days is build quality, just like always. UAW simply doesn't do as good a job as the non-union workers at the Japanese plants. Whether that's because higher per-hour labor costs make it impossible to pay them enough to torque fasteners correctly, which is a thing they seem to have trouble with, or just because they're shiftless layabouts without work ethic, the truth is that American cars tend to be assembled like shit.
If I want a car assembled correctly, I buy one which was put together in Germany or Japan, or second choice, by a Japanese company operating its own plant in the USA.
Only the top-end American cars are built from the same basic design strategies as euro cars... well, maybe and the Fiesta and Focus.
