2012 Mercedes-Benz C63 AMG Coupe

Citing sources at BenzBoost, Autoblog says that Mercedes-Benz may soon be facing a class action lawsuit over defects in its M156 V-8 engine. The 6.2-liter engine, which cranks out anywhere from 450 to over 570 horsepower, depending upon application, is used in seven different Mercedes-Benz models ranging from the C63 AMG coupe and sedan through the ML63 AMG crossover and the SLS AMG supercar.

The lawsuit alleges that material choices made by Mercedes-Benz and AMG have led to premature component wear and failure. Specifically mentioned in the suit are the engine’s nodular iron camshafts, which may be too soft or may use the wrong offset to function properly with the engine’s 9310-grade steel valve lifters. The suit further alleges that Mercedes-Benz and AMG have both been aware of the issue since 2007, when a service bulletin on the issue was released by Daimler.

While no damages have been specified in the suit, the sole (so far, at least) plaintiff alleges financial losses exceeding $25,000, both for vehicle repairs and for the loss of value in his leased (but pre-owned) Mercedes-Benz E63 AMG. Next, a judge needs to approve the suit as a class-action lawsuit, opening it up for others experiencing similar issues with the M156 V-8 engine to join in.
