They went through a period in the 90s where they had a huge leap in quality and almost matched Japanese imports of the time. I’d say GM is the only one who’s drivetrain quality is still on any comparable level with Asian imports. Ford gets some parts really right but then their beancounters make really dumb cuts to critical components that make many of their vehicles near lemons. I can’t think of a worse car manufacturer in the world right now than Stellantis, and they aren’t an American company anyway.
