Metal peeling off the bottom

This is from hitting water puddles at high speed.

You can replace that rear cover for about $300, but it's just aluminum sheets. Fortunately, this is just cosmetic and you can bend it back if you'd prefer without damaging anything.

Slow down on the puddles, or I guess you could prevent water from getting in those flaps with duct tape ? mostly kidding

That's what it looks like to me too.

Puddles? That seems crazy.

That seems like some significant under-engineering to me.

Sure. But when you hit water hard enough to feel that intense slow down, those are huge drag forces that are pulling on anything in reach of the water. I wouldn't underestimate the destructive power of water at high speed.

But I also agree, those aluminum covers shouldn't be designed to allow water to get ahold of them. Maybe someone could design an edge cover to fix Tesla's mistake here.

Definitely not a good design IF this is affecting a high percentage of CTs. A hot sealed 3M strip every few years could solve it but, redesign is the solution.

“Slow down on those puddles” is not the long -term solution for engineering or assembly issues. Anyone see this on theirs?

There are probably 10,000 cars a year damaged in this exact same manner. This is a physics problem, not a design problem.

Forward facing seam overlaps are a design problem, but I'm not sure I buy puddles. The force you feel when going through deep water is drag on the tires and has nothing to do with water hitting elsewhere on the vehicle. I guess this could be tested with a power washer, which can generate larger forces than puddles would. It is extremely hard to believe Tesla would not have done this kind of testing.

This is objectively false. F=MA. The mass of water required to reach the bottom of the CT accelerating instantly to 40+ mph is a lot more than any pressure washer I've ever heard of.

People underestimate the power of wind and water every day.

Exactly and we have no idea what other objects might be under the surface of the water when we make that huge splash.

From what I can observe in the photos, the spotwelds look like they failed. If anything those welds should have torn, but they look like they separated at the weld spots.

Zoom in on this pic. I see scrape marks before the area that folded back.

This is my truck.
