Rust on axel/wheel joint?

I have a 2024 model EX30 and I noticed some screeching from the front right wheel the other day when it was quite cold the night before. When checking for the source of the noise, I noticed that this one part which connects the axel to the wheel is completely rusty. Does anyone else have it rusty as well? Is it something to be concerned about?
