Recalls
Thor Motor Coach (TMC) is recalling certain 2016-2018 Thor Gemini and Compass recreational vehicles built on a Ford chassis and equipped with a trailer tow module. Water can enter the tow modules and corrode the wiring causing issues such as rapidly flashing turn signals, loss of instrument panel display, an electrical short and possibly the deployment of seatbelt pretensioner.
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.
