Model 3 Undercarriage Composite Tray problems

This article is for the underbody aero-shields. Looking for information on the lower side panels coming unclipped?

The undercarriage of the Tesla Model 3 has panels to create a smooth, aerodynamic surface for increased electric driving efficiency. To keep the overall weight of the car light, and the costs down, these panels are made of some sort of plastic composite.

Water, Ice and Snow

There are issues with these panels – if water or snow, or water that freezes into ice, is trapped up there, the extra weight can cause the composite panel trays to rip when driving.
