The point I was trying to make: soft paint might be the reason OP
@Saili ’s car got scratched and it is useful to consider that possibility in this particular case.
I made no claims about how widespread or not this issue might be only that there seems to have been an issue with some Model 3s in that timeframe. Maybe something happened with the painting of a subset of cars for example. Some of these clearly expand beyond the rocker panels as the paint softness seems to relate to the overall car paint, just exhibits first in the rocker panels that take most heat from the road... Interestingly Tesla says this is normal so Tesla has not identified this paint as abnormal.
I believe the Facebook group for Model 3 paint issues has like 400+ members now. Given that not all will find their way there and not all will see the paint issue immediately if it exists (meaning that if we now have 400 cases, it is not unfathomable to think the real number is at least 10x that), it seems more than a nonexistent question.
So something to consider in OP’s case.
Not saying it affects all cars at all — and of course if people have protected their paint that would mitigate it too.
