VINs of cars who lost back bumper cover?

The story that I got from reddit is this: The issue is when driving through standing water. There is a fabric material in the wheel well that saturates with water and tears. This somehow funnels more water up and in front of the rear bumper, causing it to act like a parachute and tearing it off.

Are Tesla Model 3 Rear Bumpers Falling Off In The Rain?

"A little research says that instead of using a plastic under panel they are using some sort of fiber one (note that Jeep is doing the same thing now,"

"BMW uses some type of paper fiber or cardboard type material for their undercarriage."

"Ford focus belly pan is fiber, looks like compacted flannel, wheel wells are same in other cars I've seen"
