Technical service bulletins are instructions a manufacturer sent its dealers about a known fault. They are not recalls and the work is usually not free, but they are the clearest signal of a problem the manufacturer already knows about.

MBAG has determined that on certain Mercedes-Benz Sprinter vehicles that are equipped with electrically adjustable front swivel-seats, the seat wiring harness may be improperly routed or mounted within the swivel-seat frame and could become pinched and damaged during the electric adjustment of the seat position. If the wiring harness were to become pinched and damaged during adjustment of the swivel seat, in a worst case scenario, the operation of the seat-mounted side airbag might not operate properly and the side airbag could either deploy inadvertently or not deploy as designed in the event of a crash. This condition could increase the risk of injury in the event of a crash. This affects the following Thor Motor Coach products: model year 2021/2022 Sanctuary and 2021/2022 Tranquility motorhomes.

It 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
