Recall 17V-758: Equipment

Reported Nov 22, 2017 · 110,400 vehicles affected · Thor Motor Coach

Problem: 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.
