MERCEDES-BENZ issued a recall on the ML CLASS and R CLASS models

On certain vehicles, the accelerator pedal might not have been fully fastened to its mounting studs during vehicle assembly. Due to the geometry and tension in the assembly, the mounting studs will maintain the position of the accelerator pedal but may, over time, not maintain a consistent pedal position, which could make it more difficult to operate the accelerator. Correction: Dealers will inspect the pedal assembly and, if required, install two nuts.
