    Defect, in the NHTSA record
    Thor Motor Coach (TMC) is recalling certain 2020 Daybreak, Four Winds, Delano, Gemini, Quantum, Tiburon, Chateau Citation, Compass, Chateau, Siesta, Freedom Elite, and Synergy motorhomes built on Mercedes-Benz Sprinter chassis [platform 907 (VS30)] equipped with automatic transmissions. The owner's manual does not correctly specify the certain conditions under which the automatic parking function (Auto-P) operates.

    TMC will notify owners, and a Mercedes Benz dealer will supplement the Operator's Manual with a correct description of the Auto-P function equipped in the vehicle.
