Default 2017 nx 200t idle problems

Has anyone ever has a problem with rough idle and acting like it's going to die when stoped at a light? Otherwise it runs great. Check engine light comes on.
Here is todays read out. So far, I've only replaced one o2 sensor. The one right up front. Maybe I should replace the other one too. Underneath the car.

This isn’t an O2 sensor issue. Has any work been done recently? When were the spark plugs last changed.

Default Nx idle issues

The spark plugs are new. Just talked to the dealer. They said they have been having injector issues with this model, so if that's the problem it's covered under the emissions warranty since my car only has 67,000 miles on it. I do have to pay the $225 diagnostic fee though.

What was the problem/fix? Our 2017 NX with 54k miles is having the same issues and codes. Did the dealer cover it with a TSB?
