It’s not difficult to determine what is American and what isn’t.\
Profits flowing into an American Company = American
Profits flowing out of America = Foreign
That mean’s there are only two American automakers, Ford and General Motors. Everything else is foreign.
And with regard to foreign reliability, remember that especially in the case of Japanese autos their vehicles are old. Under the skin, the Tundra is 14 years old. After all those years, they should get something right but despite this the Japanese are responsible for the largest recall in history with the Takata airbag recall, which is still ongoing.
Bottom line, if you want to keep your money working inside the USA, Ford and General Motors are where you want to look for your next vehicle.
