What will make brake lights and rear turn signal to stop working?

What is your question?

Was driving along in my 2017 Ford Fiesta SE and went to stop and almost was hit from behind due to my rear brake lights and turn signals was not working and I didn't even knew it. Got home and checked the fuses but the fuses was good. Only the 3 rd light work and rear signal lights won't work but front signal lights working.

What makes this problem better or worse?

I don't know just went out today

How long has your 2017 Ford Fiesta had this problem?
