Telematic Control Module needs replacement, but backordered with no ETA?! UNACCEPTABLE
I would like to know if this issue has been fixed. I do have issues with a very resent purchase of a used 2025 GMC Acadia and found the On Star future didn't work; no navigation, no GPS and no On Star help plus no wifi. I hope to have it taken care next month.
Hope everyone got helped!

Well, got my On-Star system (tcm module) checked Monday, they said they're going to order one, maybe come in next week. Hopefully, it does! Can't wait!

So, got the TCM replacement but still no On-Star. Now, waiting in line just like the rest of you all. No ETA on the other or should I quote the shop's dealer agent "Don't know when this module will be in". So, I like to have access to maps and wifi while traveling. I know I can use my phone but there's no On-Star incase an emergency arrises. Hope very soon!!!
