These are current. I just put my car back to stock (has been on stands for a few months) and cleared all of the codes. After a little bit of driving, this is what popped up. I'm not experiencing any other problems. The only other issue it has is the steering lock column message, but that isn't what is throwing the codes.

They really do not mean much unless other things are happening as well. The code just means the one of the periodic SOH messages that are passed between two modules was missed at a point in time. Since there are multiple messages sent between modules it normally doesn't mean anything because some of them got through. The messages can be missed because of bus activity or electrical interference from an outside source.

Unless you are experiencing actual problems of some sort related to the RFA system, these can be ignored and are just a nuisance more than anything. I've had these same three codes pop up over the years many times since I bought my car. My codes usually show an "H" (history) at the end of the number. These in particular are not uncommon.HTH
