Service bulletins

Technical service bulletins and other communications the manufacturer sent dealers about this vehicle. Ask a dealer for the full document by its number.

• 10197980MBAG has determined that on certain model year 2019-2020 Sprinter vehicles, the retaining washer on the bolt that connects the brake pedal to its bearing block could come loose. If the retaining washer were to come loose, over time it could detach from the bolt, and in the worst case and with ongoing use of the brake pedal, the bolt might separate from the bearing block on one side. If this were to occur, the brake lamp switch could become continuously activated even when the brake pedal is not pressed. If the brake lamps are continuously illuminated, it would not be possible for following traffic to determine the braking intention of the vehicle, which could increase the risk of a crash. This affects the following Thor Motor Coach products: model year 2020-2021 Citation, Compass, Daybreak, Delano, Four Winds, Freedom Elite, Gemini, Quantum, Siesta, Synergy, and Tiburon motorhomes.

• 10197969On certain model year 2012 2018 5-ton Sprinter vehicles that were upfitted into campers or recreational vehicles (RVs), one or more of the rear-wheel speed sensors may experience an electrical failure, which potentially could lead to a disablement of the Electronic Stability Control (ESP) control unit functions. If ESP control unit functions are disabled, vehicle driving stability may be impacted under certain driving conditions, increasing the risk of a crash. This affects the following Thor Motor Coach products: model year 2013-2020 Chateau Citation & Four Winds Siesta, 2017-2019 Compass, 2017-2020 Four Winds, Gemini, Quantum, Chateau, & Synergy, and 2018-2020 Freedom Elite motorhomes

• 10197609It has been determined that on certain Mercedes-Benz Sprinter vehicles, the hydraulic power steering return line hoses might detach at their connection points under certain operating conditions, which could cause hydraulic fluid to leak, resulting in the loss of power steering assist. If the hydraulic power steering hose detaches, the driver will still have manual steering functionality, but increased steering effort will be needed, particularly at low speeds. Sudden loss of power steering assist as well as the loss of hydraulic steering fluid to the road surface may increase the risk of a crash. This affects the following Thor Motor Coach products: 2017-2020 Chateau, Chateau Citation, Four Winds, Gemini, Quantum, Siesta, & Synergy; 2018-2019 Compass; 2018-2020 Freedom Elite; 2021 Sanctuary & Tranquility
