I got an ECM (Engine Control Module) voluntary recall notice (#N192273630) on 4/13/20.
Due to "The engine control module in these vehicles may not adequately diagnose or illuminate the malfunction indicator lamp (check engine light) when frequent regeneration of the diesel particulate filter occurs."
I took it in on 4/14/20. 30 minutes later, all done. Time will tell if any major differences occur.
 
I've had it completed on one of my 3 cars and have not seen any difference. Based on the description, the programming change was to allow a MIL (Check Engine Light) to be triggered if the car is doing regeneration events too often. This was also a recall for the 2.8 Duramax engine that has very similar engine computer programming.
