2015 Honda CR-V wheels problems

Tl*the contact owns a 2015 honda cr-v. The contact stated that while driving approximately 40 MPH, the entire vehicle began to vibrate. The contact inspected the four wheels equipped on the vehicle and noticed that water was trapped inside of the wheel and would freeze during frigid temperatures. The contact stated that snow and ice buildups caused the vibration. The vehicle was not repaired. The manufacturer was notified of the issue. The approximate failure mileage was 150.

The part is protector 91720, pn: 52352-t1g-e01. It is small plastic part to protect real wheel axle or body structure in the bottom of the car. When my car has some vibrate (it did not hit anything), the part fallen to the floor. And one side of the part is still on the car. It made the car speed suddenly slow because the one end of parts is dragging on the road. The part is no screw on fallen side. The part is broken now. The dealer agent told me it is not on the car warranty and I need pay it.
