2022 Silverado 1500 ECM and TCM codes


Recommended Posts

I have a 2022 Silverado 1500 with the 3.0L Duramax in it with less than 1,300 miles on it and has the check engine light on. Called ONSTAR for the codes and it currently has either 11 or 12 codes all relating to the ECM and TCM communication issues. Has anyone else experienced these issues? Dealership can not get me in to look at the truck until next week which is frustrating having a brand new truck with issues already.
