5BW 265 miles on the odometer and CEL popped up today. P3173 is what onstar reported back. At the dealer now having it looked at. Anyone else??

Here's a reference to it:

New Ct4V Blackwing check engine light from dealer

Wanted to see if anyone else had gotten these engine codes, as I cannot find them online. Just bought a ct4V blackwing the other day and it had a check engine light when I took delivery. I pulled the codes, and saw them to be 'P3173' and 'P3175'. If anyone has seen these before and knows what...

Luckily I was right by Sewell when it happened. Exhaust valve was stuck and needed a reprogramming. Reprogrammed and I’m on my way. Hoping it doesn’t pop up again.
