Lawsuit Filed Against Mercedes-Benz AMG 6.2 M156 Engine Over Potential Defects
Mercedes-Benz is facing a class action lawsuit due to a defect in the 6.2 liter M156 engine developed by AMG. The alleged defect leads to premature wear of the engine and engine failure. The M156 engine powers many of the popular Mercedes cars like the C63 AMG and the E63 AMG.
The class action lawsuit has been filled at the U.S. District Court of New Jersey. The automaker had previously filed a report about the potential problem, but has not yet issued any recall or revealed the probable number of affected vehicles.
The lawsuit was filed by a previous owner of the 2007 Mercedes-Benz E63 AMG, who has claimed that problems in the valve train have lead to premature wear of the engine. In the lawsuit, it has been alleged that the camshafts made of nodular iron and the valve lifters made of 9310 grade steel were either improperly heat-treated or installed with improper offsets.
The plaintiff has claimed that his E63 AMG had problems in the engine due to considerable wear on the left bank camshaft. The issue was not covered under warranty and the replacement cost him $4,594.26. After three months, he experienced the same problem on the right side of his engine and decided to sell his car. The plaintiff has claimed that he has suffered financial losses worth $25,000 in repairs and in the loss of value in his leased (but pre-owned) Mercedes-Benz E63 AMG.
Donna Boland, Corporate Communications Manager at Mercedes-Benz USA, said that the automaker is aware of the lawsuit. She also added that engine is not defective and the customer’s engine appears to have run for tens of thousands of trouble-free miles.
