Update on my 2023 Silverado 1500 5.3L HC made in Canada. Sorry for not update my problem, but i took it to my service man and he found out that the truck was searching for a hybridmodule i think it is called K16 and trying to connect to that, so the truck was looking for K16 day and night. But my truck is not a hybrid so after a while they finally changed my cluster and reprogram the truck. Now everything runs perfect and no issues at all. / H

Yes nothing that takes power when you test and no aftermarket items. I just shut the automatic update and installation of new program until i hear anything from workshop.

I have a Silverado HC 5.3L that after 2 month started to drain battery. Now it happend three times during a month and It seems it drain the battery overnight. Sometimes just after i have been in truck the day before not driving just getting things out of the bed. It is complete dead no fob or interior comes on. I have taking it to dealer and they are waiting for GM on what is causing the problem. Anyone with same problem ? / Hans
