Here are my thoughts. I worked for Toyota for many years. I have also worked for Gm. I have seen it from both sides.
Lets take a window motor for example. Toyota will give thier supplier a certain build thier looking for. They will specify a certain fail per 1000 parts. This is where you get the long term reliability. The difference between Toyota and Lexus is even bigger. If they specify 5 failures per 1000 on a toyota it might be 1 or 2 per 1000.
