NHTSA Complaint #11468003 — 2021 TIFFIN WAYFARER

The Tiffin Wayfarer is built on a MB Sprinter 3500 chassis. Tiffin adds rear wheelwell liners made of plastic. These liners are held onto the chassis by 4 screws all on the outside of the liner. There is no inside support of the liner or reinforcement of the screws. My right side liner detached while traveling on I-81 in PA at 65 mph. It went under the wheels which caused the vehicle to bounce and it acted like a blow-out. I pulled over and could see no significant damage and there were no warning lights so we kept traveling. Luckily there were no vehicles behind us as they would have had plastic shooting at them. I removed the left side liner when I got home and found that it was being held on by a single screw as the other 3 points had failed. I have enclosed a PDF showing the left side liner damage. The mounting is totally insufficient. Other owners have stated that they also have had the liners come off and one owner said his rubbed to the point where it melted. I have attempted to contact Tiffin Wayfarer without success. No insurance or police were involved.
