I agree with you. He have accepted poor American quality. And so much so, the Japanese brands build their cars in American to those same poor standards. Hence I will never own an American made Honda after a long line of honda's in the family. Once things started breaking in my sister 06 honda accord, I knew the quality was poor, and my transmission was replaced 5 times in my 2001 Acura TL. My infiniti G35 was great, but was built in Japan (you can tell by the J beginning to the VIN number). And my friends Acura TSX is a champ with over 230k miles with just reg maintenance (also made in Japan unlike the TL and Honda vehicles). My wife's 2014 RDX blew a head with a stuck valve within 3k miles of ownership.
The only reason I drive domestic (last two cars were Escalades, and had a tahoe before that). Is of all the American built cars, I trust the LS based motors. Though the small bits on the car may fail, the motor will last long enough to get me to 100k miles when I'll buy another car.
If we want American cars to be great again, they have to be built great again. Problem is, ACROSS the board, with ALL mass manufacturers, they are built to a price point. To maximize profits, they are only willing to invest so much, Plus they DO NOT WANT to make a car last forever. They purposely choose parts with a certain life cycle. They don't make money unless they sell you a car, and they need you to buy a new car every few years.
