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.

On certain Model Year 2020 Sprinter vehicles, the screws for the front door hinges may not have been tightened according to specification. If the door hinge screws are not tightened with the specified amount of torque, itâs possible that the pre-tensioning force of the screw could decrease and eventually cause a change in the opening/closing behavior of the door, as well as changes in door gap dimensions. This 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 2022 Tranquility motorhomes.
