From what I’ve read, this looks like signs of a bad radiator cap. Am I correct?
I am talking about the white spots. That is what OAT antifreeze does, right?

It could be, although mine has done that a few times over the years. They're cheap to replace. Or you can wipe it down and check more frequently to see if it's a one off or happening every time you drive it.

I'm still on my original cap on my 2013.

That’s what I’m going to do. I know that it happens, but I have never seen one go bad.

Look at the seal on it to make sure it's not dirty or cracked. The pressure part of the cap is the smaller part of the cap when you look at it when it's off.

I cleaned everything and have been driving as normal for the last 4 hours. Hopefully I just had a little premature concern. 🤷🏻‍♂️
