Do automakers REALLY test long-term durability on engines and transmissions or is the consumer the ones who are the testers. Ford explorer 2001-2010 4.0 3-4 timing chains in that engine that had issues. Ford 5r55s/w transmission servo problems steel piston s moving in aluminium bores. GM Colorado bad cylinder heads. Why do so many years go by before the issues are resolved if they ever are. The two Ford issues i mentioned were resolved 9 years later when they stopped making them. How many cars or trucks have to be affected before a recall? If manufacturers really tested the items i mentioned don't you think they would find the problem BEFORE they sell them to the consumer. You guys can probably list so many more examples then i can.
