2015 civic hybrid u0029
 

New to me car from carmax.
It's still within the 30 days returnable state.

I filled up with gas and started the car again at the gas station. All the lights came and and a bunch of error messages flashed on the screen. I'm sorry, but I don't remember what they were.
The check engine light came on. I checked it with the obd2 scanner and u0029 came up.
What is that error?
I did some looking around and read a drive battery change fixed the issue.
Has anyone heard of that u0029 error?
Should I return the car and get another?
Thank you so much everyone!
I unplugged the battery for 30 seconds and the error went away and hasn't come back in 50 miles.
