Newmar Corporation (Newmar) is recalling various 1995-2018 motorhomes. A list of the affected vehicles available at: https://static.nhtsa.gov/odi/rcl/2017/RMISC-17V809-2309.pdf. These motorhomes are equipped with Kidde Plastic-Handle or Push Button 'Pindicator' Fire Extinguishers that may become clogged, preventing the extinguisher from discharging as expected or excessive force may be needed to activate the extinguisher.
