Do American manufacturers also put diseases in the glove compartment?

Hello US Car community, when little boy was pulled by father into the BMW virus at that time it was early a 3.5L V8 ( E39 535i ) and after another 2 years a 4.8L V8 ( E60 550i ) The E39 was BJ 2000 – with 210tkm bought – except service and times a water pump and fuel pump nothing. The E60 is BJ 08 had 122tkm – now with 133tkm -> Valve shaft sealing damage BMW does not take over any cent. If you leave the BMW forums there are still more gross diseases Since I absolutely no lust dara uf have to support the new policy of this manufacturer the vehicle will be sold… But enough of the negative How does it look with the diseases of the V8 engines the well-known models ? – Charger – Mustang – Camaro – Chalanger – Corvette Is anything else vulnerable to the bodies / mechanics / electrics ? Of course here and there something is broken – is after all material. But I subordinate BMW that there is intentionally saved – to hire a self-appointed Premium Herst What does it look like with the Americans ? Also on a savings course ? Thanks already now for every helpful and critical answer Greeting from Karlsruhe
