What 2018 Thor Motor Coach Four Winds owners say
Most recent owner complaints, unedited.
Twice! Wheel rim developed a hairline crack in the weld adjacent to the valve stem. 2-times, different rims - both on inside dually rear - one left and one right side. 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 consumer is left at risk. Human safety is at great risk!
Incorrect weight distribution. Back of vichicle to low,which causes front to be to high. Unable to maintain lane when beng passed by a big rig or side gust of wind. Vichicle very unstable,should not have been sold in that condition.
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.
