When I read this problem, I am quite surprised but, that's life. I long ago supplied with a factory partner parts for car industry, it is big quantities at hardly discussed price. Sometimes they acceted a better price for a lower quality.... they knew it. And each month I receive my magazine about quality life... and there is one page for cars called back by factories for various problems : Audi, BMW, Mercedes, and others have sometimes problems, these are new cars! And it can be dangerous. I believe that I dream, but it is true! This is not very serious in my opinion.
