On 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","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2021/MC-10197968-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2021/MC-10197968-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10197968","components":[{"id":"electrical","name":"Electrical system","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"THOR MOTOR COACH","model":"CHATEAU","year_from":2013,"year_to":2017,"match":null,"vehicle_ids":[]},{"make":"THOR MOTOR COACH","model":"CHATEAU CITATION","year_from":2019,"year_to":2020,"match":null,"vehicle_ids":[]},{"make":"THOR MOTOR COACH","model":"COMPASS","year_from":2017,"year_to":2019,"match":null,"vehicle_ids":[]},{"make":"THOR MOTOR COACH","model":"FOUR WINDS","year_from":2013,"year_to":2018,"match":null,"vehicle_ids":[]},{"make":"THOR MOTOR COACH","model":"FOUR WINDS SIESTA","year_from":2019,"year_to":2020,"match":null,"vehicle_ids":[]},{"make":"THOR MOTOR COACH","model":"FREEDOM ELITE","year_from":2018,"year_to":2020,"match":null,"vehicle_ids":[]},{"make":"THOR MOTOR COACH","model":"GEMINI","year_from":2018,"year_to":2020,"match":null,"vehicle_ids":[]},{"make":"THOR MOTOR COACH","model":"QUANTUM","year_from":2017,"year_to":2019,"match":null,"vehicle_ids":[]},{"make":"THOR MOTOR COACH","model":"SYNERGY","year_from":2017,"year_to":2019,"match":null,"vehicle_ids":[]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
