R Elam. I did the same type of thing with a 2week old S. That is not part of the battery and totally cosmetic. There is an aluminum plate bottom for the battery. I hung mine up on a pointed rock hitting the battery plate,also. 2 years later all still fine. Tesla’s are tough underneath.Without more detail, I can't say. It's tough to tell from the pictures what/where is damaged, but it looks minor. Generally speaking, the bottom of cars are pretty resilient. Unless there is a major gouge, I wouldn't worry too much, but a Tesla SC can provide peace of mind. When I hear "curbing", I think of a rim hitting a curb, JFYI.
