Electric power steering issues

So I'm pretty sure my electric power steering is going out. I had the Jeep serviced today and when they were pulling the Jeep out I heard a little whine. I thought it was my fan at first because it was warm and the a/c was on. I had to shut off the Jeep in the drive thru and when I went to start it....it just gave a bump. That was weird so when I started it again the check engine light was on and the power steering wasn't there. I ran it over to the dealer and when she started it up the power steering came back! I noticed on my cross country trip i would smell some kinda gear oil on the trip. Its hard to recognize because that's a long trip with a lot of cars. I noticed the steering even would feel weird at times when I was backing out the Jeep. They reset the codes and made a note so when I come back they can look at it. I checked the battery, the can buss, and looked at all the connectors. Im at a loss because it seems to be fine now even though I know it's probably not. Here is a list of the codes they gave me.1000011962.jpg
 
Update: Took it back to the dealer and they said everything looked good 🤷‍♂️ I'm pretty sure they didn't test the batteries. The Jeep sat there all week without starting so I'm doubting that is it, but who knows. Maybe it was a computer glitch. Guess I'll just keep driving it and see what happens.
