Thor Motor Coach (TMC) is recalling certain 2018 Thor Chateau and Four Winds motorhomes and 2019-2020 Magnitude and Omni motorhomes. The backup camera displays may revert back to the factory default settings which may cause the camera image to be reversed.
Thor Motor Coach (TMC) is recalling certain 2018-2019 Thor Four Winds, Chateau, and Freedom Elite vehicles. The liquid propane (LP) hose may not have adequate space between the floor and the metal plate on the refrigerator, causing damage to the hose and possibly creating a propane leak.
Thor Motor Coach (Thor) is recalling various 2003-2018 recreational vehicles, equipped with Kidde Plastic-Handle or Push Button 'Pindicator' Fire Extinguishers. See a list of the affected trailer models at: https://static.nhtsa.gov/odi/rcl/2017/RMISC-17V758-5764.pdf. These extinguishers may become clogged, preventing the extinguisher from discharging as expected or excessive force may be needed to activate the extinguisher. Additionally, in certain models, the nozzle may detach from the valve assembly with enough force that it could cause injury and also render the product inoperable.
