• Class action suit against Daimler AG / Mercedes due to M156 V8 (63 AMG) engine defects

      A class action suit is being brought against Mercedes / Daimler AG due to alleged defects in the M156 V8 motor. The suit states that these defects are due to premature wear. The premature wear taking place as a result of the material used in the camshafts. The camshafts used are made of cast nodular iron. The valve lifters used however are made of 9310 grade steel. In the official complaint it is stated that the combination of these metals as designed is contributing to premature wear of the M156 motors. This can be due to improper heat treating of the metals or improper offset. The main sticking point is that Mercedes and AMG have known about this since 2007 when service bulletin S-B 05.20/20b was released. We will keep you updated on the details as this goes forward.

        AMG is a subsidiary of Daimler AG. No more, no less. Mercedes has been sued before for product defects and Sherman Act violations successfully. They aren't they god of immune corporations.

        You act like it never happens. Just because they can toss money at lawyers does not mean they can do whatever they want.

        You mean best of luck to all M156 owners. The suit is on behalf of all of them...and that includes benzboost members. I don't know why any of them wouldn't support this since it's in their best interest to do so.

        You're not going to tell me why you speculate the more money a corporation has, the more immune they are to the law?

        Because, you can't. It doesn't work that way. Give me the name of the biggest corporation you can think of and I'll show you a lawsuit where they had to pay money.

        Have you opened their engines and looked at the parts for premature wear? Your focus is completely misplaced.

        I have no clue what the explanation would be to that particular owner. We would need to hear from them directly.
        Probably where the Mag-Moss portion of the claim came from.

        Sticky, are there any links to threads from owners that have had this problem. This is still the first I have heard of this. You had heard of engine failures.

        The E63 owner in this lawsuit makes it seem like it is as widespread as the N54 HPFP.

        Shouldn't you be focusing more on Daimler addressing any potential motor issues? Or do we live in a world where we need to pay more attention to the army of lawyers they can afford instead of taking accountability for manufacturing and engineering?

        I don't understand why some of y'all have a hard time believing this when you haven't even seen these parts. It's not like the lawsuit is claiming extra terrestrials are real.

        Hey, the Mag-Moss act is why I didn't have to pay for the entirety of my repair work on my M3.

        I don't think it is anywhere near as widespread as the HPFP and it is a completely different kind of issue.

        I don't have any links but let me just say this is not the first I heard of this lawsuit.

        Because people don't want to believe something might be wrong with their motors.
