Vehicles Affected: Approximately 800 model-year 2017 Mercedes-Benz E400 4Matic coupes, E400 convertibles, and E550 coupes and convertibles, all manufactured between June 7 and Sept. 8, 2016
The Problem: There may be insufficient clearance between the left catalytic converter and the composite underbody panel, which may cause the panel to melt, increasing the risk of a fire.
The Fix: Dealers will inspect and replace the underbody panel, as necessary, for free.
