Only 39k miles. I'm gonna get it checked out ASAP. Does anyone have an inkling what it might be if I experience rough idling from a cold start? i.e. lots of vibration. It's not present with a warm start.

Hopefully it’s no big deal. You should look into an OBD2 reader. Plenty of cheap ones on Amazon. Quick question, did you have wrist pin issues?

I took my car (40k miles) in yesterday for the same issue. The car has a slight vibration on cold start. My 2018 loaner is doing the same thing. So this may not be an issue.

I hadn't noticed the vibration as much before though. And the check engine light doesnt come on for no reason.
