It’s an absolute beast of an engine. Generating some 525 horsepower in its current form, Mercedes-Benz’s  M156 6.2-liter V8, developed built by AMG has transformed some of the brand’s regular offerings into pavement eating road warriors. Cars such as the C63 and E63 AMG have become modern legends thanks to the incredible performance offered by this monster motor.

However for all it’s rip snorting ability and melodious sound, the 6.2 has recently come under flack in New Jersey, as a class-action lawsuit has been filed in the Garden State’s District Court.

The suit centers around premature wear on the engine’s internal components, particularly on the nodular cast-iron camshafts and 9310-grade steel valves. Plaintiffs complain that due to inadequate heat treating of components and incorrect offsets, engine failure is a common problem with the 6.2. To make matters worse, plaintiffs cite the fact that Mercedes and AMG have known about these issues since 2007 when the automaker issued a technical service bulletin to deal with the problem.

At present no actual trial date has been set, nor has any information been released regarding the number of 6.2-liter V8s ‘affected’ by this problem. Still, it will be interesting to see what further developments arise in this case and if a recall is issued covering Mercedes models powered by these ‘defective’ engines.

    Once I initially commented I clicked the -Notify me when new comments are added- checkbox and now every time a comment is added I get 4 emails with the same comment. Is there any way you possibly can remove me from that service? Thanks!

    I have an SL55 AMG that had a catastriphic engine failure last week. I only have 69,000 miles on my car and I am being “rushed” to buy a new engine. Now I need to find out how I can get included in the class action suit.

    I think everything posted made a ton of sense. However, think about this, suppose you added a little information? I mean, I don’t want to tell you how to run your website, but suppose you added a headline to possibly grab people’s attention? I mean Mercedes Benz Facing Class Action Lawsuit For AMG V8 Defects | AutoGuide.com News is kinda boring. You should look at Yahoo’s front page and note how they create article titles to grab people interested. You might add a related video or a related picture or two to get readers interested about what you’ve written. Just my opinion, it might make your posts a little bit more interesting.
