Just picked up my 2022 2500 diesel and promptly (15 mile on the Odometer) got a check engine light and it displays a Service Air Filter message under slight load. Back to dealer and they replaced the MAF which seems to have quieted down the check engine light (so they say) but not the Service Air Filter message. Tech opened a case with STAR, but I still don't have my truck back. I searched and saw nothing on point, but checking to see if anyone else has run across this and how it was resolved.
