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.

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.

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.
