The Problem: All-season floor mats, sold as an accessory, may not completely conform to the floor, potentially reducing clearance between it and the accelerator pedal. As a result, the pedal could become trapped, which would prevent it from returning to its normal position after the driver lifts their foot. The vehicle may not decelerate as expected, which could increase the risk of a crash. Slowly applying the brakes will bring the vehicle to a stop, however.
The Fix: Mercedes will begin notifying owners in September, when dealers will replace floor mats free of charge. Mercedes advises owners to remove floor mats until new ones can be installed. Owners can contact Mercedes at 1-800-367-6372 for more information.
Number of Vehicles Potentially Affected: 8675 M-Class SUVs equipped with accessory floor mats including 2012-2013 ML350, ML550, and ML63 AMG models.
