This seems like a problem unique to engine with CD (cylinder deactivation) (18+, non-turbo).

jjm86m print off the document https://static.nhtsa.gov/odi/tsbs/2019/MC-10159203-0001.pdf with the line 'inspect for any rocker arms that are broken or have fallen off' highlighted and take it to your dealer and have them look for that.

And bring your original work order with you. If they checked for the valve assembly damage it would be on your original work order, I would think.
