I wanted to subscribe to this thread. Both codes have been appearing for me. Usually appear every 2 weeks and disappear after few days. Did anyone with these codes was able to get this fixed?

Very interesting, we both have 2017's. Mine have not returned since I first cleared them, ~1k miles now since.

Have you changed your oil? How many times have they shown up? That was the only thing that had any sort of correlation between my codes that I could remember. Maybe double check that your dipstick is seated fully and oil cap is snug. Makes little sense to me why this would cause those codes so if your scratching your head, trust me I am too.

My codes are popping up quite frequently. Every 100 miles or so. I also don't clear them and wait until they go away. The codes always appear few minutes after cold start. I can't think of any correlation between these and oil changes.

Interesting, the only time mine showed up was after a cold start heading to work a few minutes into the drive at most.

that is true, it always appears after cold start, but once in a while. Do you have warranty? My car has voided warranty because i bought it salvage with suspension damage, not engine related.
