I have a 2017 Malibu Hybrid w/83,000 miles. I got a CEL w/P015B code, I had (2) o2 sensors replaced and CEL came back on after 2 days. Once cleared, it seems to come back on about every other day. Has anyone else had this issue?

I haven't had that issue, but there can be many things wrong than can trigger the O2 sensor code. One of which is a dirty engine air filter. Your sensor might not be bad. You can read about it in the link below.

possible that the adaptive memory doesn't recognize the different resistance of the new O2 sensor.

Would this be something dealer corrects with a “flash” or is there “DIY” sort of reset?

well, not necessarily a flash, although every drive-ability school I go to they tell us to flash the PCM to the current programming before proceeding..
It's just a "reset" of the adaptives to make sure the car doesn't learn bad habits.

...and dealer would be able to do this? Thanks

I am having the same problem with my 2017 Malibu hybrid. Did you ever figure out your problem and the fix. Mine has been in the shop for more than 2 months and still not fixed.
