ONCE YOU GO ABOVE 40 MPH THE STEARING WHEEL STARTS TO SHIMMY AND THE FRONT END VIBRATES. IT TAKES ALL YOUR EFFORT TO HOLD IT ON THE ROAD UNTIL YOU REACH THE SPEED OF 70 MPH OR MORE. THIS HAPPENS WHILE TRAVELING ON MAJOR HIGHWAYS LIKE I95.

Owner report 11436297 · 2021-10-11 (October 11, 2021)

The first happened on our first long trip in 2019. The second time was on the next long trip of 2021. Internet forums are showing that this is a rather "COMMON" issue! Plus, Mercedes has recorded lawsuits with similar rim weld failures on other Mercedes vehicles. I get NO sympathy or compensation through Mercedes or Thor - They each kick the can to the other, and the consu…

17V634000 · Equipment:Other:Labels

Thor Motor Coach (TMC) is recalling certain 2017-2018 Challenger, Axis, Chateau, Four Winds, Hurricane, Miramar, Palazzo, Tuscany, Vegas, Venetian, and Windsport motorhomes.

Consequence: 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.

Remedy: 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.

17V758000 · Equipment

Reported: 2017-11-22 (November 22, 2017)

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

Consequence: In the event of a fire, if the fire extinguisher does not function properly, it can increase the risk of injury.

Remedy: 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.
