This popped up on me a few days ago. Disconnected battery and it went away for a few days and now it's back.

No real issues or symptoms other than CEL and some kind of traction light.

Just had my SC installed not too long ago. Could this be an issue?

Code is "lean on bank 1". I'm assuming its an o2 sensor? What else could it be?
Dealer said that would not be covered under warranty do its on me I guess and I can replace something if need be!

Well, in case anyone else has this issue I figured I would post the resolution.

After looking at it there was a split vacuum hose, replaced and cleared codes. All better. Dealer did it for free so I was pretty excited.
