If the Japanese have it figured out then why do they also keep having recalls and having to extend their warranties as well. No-body is building a perfect vehicle yet. 
No one is perfect but some are far LESS perfect than others.
Recalls are not desirable but they are an acknowledgement of a problem. As opposed to simply say replacing a defective part with another defective part in hopes of the part lasting until warranty expiration.
It took a long time for the Mg's and Fords of the world to get INTO these poor financial positions especially when itys overcapacity. It will take a long time to get out.
