The clock is slow to update for some mysterious reason. At the daylight savings time switchover my clock sometimes doesn't update for a day or two. Patience, grasshopper.
OnStar can reset your ATT connection.Thanks - no ATT signal icon is displayed (we are in Phoenix).
The car is a 2020 Premier

It was fine before we took it in for service
I meant to check last time I was in the car, but I forgot. I see you've already slain that time dragon.Thanks shrox, does yours display the ATT Signal icon? Ours does not
What he said 👆
The OnStar module has to receive the update from the cell network to change the time. If not happening, just manual change the hour. No biggie. There are other things to worry in life, IMO.
I don't think an update to the OnStar module is necessary as I was able to get LTE connectivity back to my Bolt by activating an 3-month OnStar trial. LTE returned literally while I was on the phone with OnStar asking questions but before I gave them my credit card info.Problem solved (kind of)…
Called OnStar back and was fortunate to get an advisor that was willing to reset the system (which restored the ATT Signal, fixed the clock, etc). During the call the OnStar system light started flashing red so back to the dealer next week to fix whatever is causing the system to hiccup as it goes back and forth between red and green.
No issues with this before the Battery swap, maybe just coincidental.
Thanks for the help 👍
