Quick answer

Why the warranty extension? On certain Model Year 2011-2016 CL/CLS/S/E/ML/SL/G/GL/GLE-Class vehicles with V8 engines, the exhaust valve assembly might not work properly and result in an engine misfire and potential illumination of the check engine Malfunction Indicator Lamp (MIL).

What this bulletin may mean before buying

Treat this as service research, not a verdict on one car. Before you buy, compare this communication with official recall campaigns, model-level owner complaint patterns, and the exact vehicle’s VIN-decoded specifications. A bulletin can help you ask a seller or dealer sharper questions about software updates, known repairs, warranty extensions and service history.

Why the warranty extension? On certain Model Year 2011-2016 CL/CLS/S/E/ML/SL/G/GL/GLE-Class vehicles with V8 engines, the exhaust valve assembly might not work properly and result in an engine misfire and potential illumination of the check engine Malfunction Indicator Lamp (MIL).

How should a used-car buyer use this bulletin?

Use it as a research signal. Compare it with recalls, owner complaints, service records, a VIN report and an independent inspection before buying.
