Official manufacturer communication context for 2021, 2022 Thor Motor Coach Sanctuary, with affected products, buyer checks and links into Carchieve recall, problem and VIN research.
Reviewed June 2026 from NHTSA manufacturer communication and service bulletin records. Carchieve is independent and not affiliated with any vehicle manufacturer or government agency.
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.
