Tap a recall to see the problem, the risk and the fix.
Visibility
Problem: Thor Motor Coach (TMC) is recalling certain 2017-2019 Thor Challenger, Miramar, and Outlaw motorhomes. The motorized windshield roller shade at the driver's seating position may unroll without warning while driving.
Risk: If the windshield roller shade unrolls while driving, it could block the driver's visibility, increasing the risk of a crash.
Fix: TMC will notify owners, and dealers will install a fastener to ensure the motor will not allow the shade to roll down during while driving. The recall began January 10, 2019. Owners may contact TMC customer service at 1-877-855-2867. TMC's number for this recall is RC000165.
Equipment
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. For a full list of the affected fire extinguisher models visit: https://static.nhtsa.gov/odi/rcl/2017/RMISC-17E062-5427.pdf
Risk: In the event of a fire, if the fire extinguisher does not function properly, it can increase the risk of injury.
Fix: Thor will notify owners, instructing them to contact Kidde for a replacement fire extinguisher, free of charge. The recall began on January 15, 2018. Owners may contact Thor customer service at 1-877-500-1020, or Kidde customer service toll-free at 1-855-262-3540, or online at www.kidde.com and click on "Product Safety Recall" for more information.
Equipment:other:labels
Problem: Thor Motor Coach (TMC) is recalling certain 2017-2018 Challenger, Axis, Chateau, Four Winds, Hurricane, Miramar, Palazzo, Tuscany, Vegas, Venetian, and Windsport motorhomes. The cargo carrying capacity (CCC) label on these vehicles may indicate an incorrect water capacity for the water heater/fresh water tank. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 120, "Tires and Rims for Motor vehicles over 10,000lbs."
Risk: If the water capacity information is incorrect and it causes the vehicle to be over loaded, there would be an increased risk of a crash.
Fix: TMC will notify owners and send them corrected labels, free of charge. The recall began on November 15, 2017. Owners may contact TMC customer service at 1-877-500-1020. TMC's number for this recall is RC000147.
