Defect

Mercedes-Benz is recalling certain accessory all-season floor mats sold for use in model year 2012 and 2013 Mercedes-Benz ML-Class vehicles. This all-season floor mat may not fully conform to the contour of the vehicle's floor plan as intended. Clearance between the mat and the gas pedal may be reduced, possibly allowing the pedal to become trapped.

Consequence

This interference could prevent the gas pedal from retracting and the vehicle may not decelerate as expected when the driver lifts their foot from the gas pedal, which could increase the risk of a crash. Should the pedal become trapped, steady application of the brakes will allow the vehicle to be brought to a stop.

Remedy

Mercedes-Benz will notify owners, and dealers will replace the floor mats free of charge. Until replacement mats become available, consumers are advised to remove their floor mats from the vehicle. The safety recall began on December 21, 2012. Only vehicles equipped with the accessory floor mats are affected. Owners may contact Mercedes-Benz for more information at 1-800-367-6372.
