Bought my truck new April 2023. Like most new GMC Sierra they come with 2 year subscription with OnStar. My two year subscription expired two days ago 4/17/25. The same day it expired my OnStar functions all went out and my battery light came on. I didn’t notice anything wrong with the way the truck was running, I just notice all functions like the blue bottom, SOS button, GPS etc weren’t working. I was unable to call OnStar through the blue button. After, having a scan done the report showed two faults, P00FF- BCM and P0562 Low voltage.  After, having the mechanic check the BCM, Battery and alternator out, everything tested to be positive with no issues. So, I decided to renew my OnStar subscription to shortly find out from OnStar that my truck needs to go to the dealer to have new OnStar module put in. It seems odd how all this happened at the same time of my subscription expired. Everything was working just fine and no check engine prior to expiration date. Anyone else having this issue?
