Mercedes-Benz Equipped With M156 Engine Are Defective. A lawsuit has been filed in federal court in New Jersey alleging that Mercedes-Benz vehicles equipped with the M156 engine are defective and prone to premature wear. The lawsuit seeks class action status on behalf of consumers who own or lease 2007 through 2011 Mercedes-Benz vehicles equipped with the defective M156 that were sold or leased in California.
Daimler AG, a defendant in the lawsuit, introduced its M156 engine, a 6.2-liter V8 engine, in its AMG vehicles starting in the 2007 model year, the suit says. The M156 is the first V8 automobile engine designed autonomously by Mercedes-Benz subsidiary Mercedes-AMG, as previous AMG engines have always been based on original Mercedes engines.
Engine Does Not Perform As Promised
But according to Cedric Chan, a California resident and lead plaintiff in the lawsuit, the engine does not perform as promised. According to the complaint, Chan has spent roughly $4,600 since he purchased a pre-owned 2007 Mercedes-Benz E63 AMG in 2008. When the vehicle required even more engine repairs, Chan decided instead to trade it in, incurring a $25,000 loss. The lawsuit alleges that Daimler has known about defects in its M156 engine since introducing it in the 2007 model year and has revised service bulletins for mechanics covering replacement of engine parts.
“As an owner or lessee of numerous Mercedes vehicles in the past, plaintiff expected to receive a product that conformed to the quality that Mercedes advertises for its AMG products,” Chan’s suit contended. “Alas, plaintiff did not even receive a vehicle that conformed to the lesser (but, still high) quality of Mercedes non-AMG vehicle line.”
