As some of you might know, the AMG 6.2-litre engine is a popular engine that powers many Mercedes-Benz AMG models, including the C 63 AMG and E 63 AMG, as well as other models in various tunes.
Well, the German company Mercedes-Benz is reportedly facing a class-action lawsuit in the U.S. District Court of New Jersey for alleged defects involving the M156 6.2-litre AMG V8 engine. The car maker has previously filed a report about the potential problem but has not issued a recall or stated how many vehicles could possibly be affected.
Filed by a previous owner of a Mercedes-Benz E 63 AMG who claims that the engine wore prematurely due to problems with the valvetrain, the lawsuit say that the engine’s camshafts, made from cast nodular iron, and the associating valve lifters, made from 9310 grade steel, are either not installed properly from the factory, or are not heat treated correctly which causes early wear.
The owner who filled this lawsuit says that his now-sold second-hand E 63 suffered engine failure due to considerable wear on the left bank camshaft and he was upset because he paid US$4594.26 to have the problem fixed because the issue was not covered under warranty.
In addition to that, three months later, the right cylinder bank camshaft suffered the same problem, so he had to sell the car. The plaintiff claims that this situation put him at a loss of $25,000.
According to Car Advice, up to three different lawsuits have apparently been filed against Mercedes-Benz surrounding the same issue, with the main complaint being that Mercedes-Benz has been aware of such potential defects, but has not issued an official recall.
