Why would I experience vaginal bleeding years after a hysterectomy?

This is a question that has been asked several times on the forum so you are not the only one having this problem. It could be caused by all kinds of problems and only your GYN can get tests done and answer that question. I would see him/her ASAP.

A matter to take to your doctor. There are many possible reasons; only your doctor can tell them which might be a problems for you.
