These conditions may increase the risk of a crash. This affects the following Thor Motor Coach products: model year 2019 Quantum & Freedom Elite, 2019/2021 Daybreak & Four Winds, and 2019-2021 Chateau motorhomes.

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.

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

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
