From the wording, I'll guess it has to do with the ability to call after a crash, but I've never seen that message in mine, so a guess is all I have.

 

Normally I would say to have OnStar give you fault codes. But with this error, I suspect they can't - even if you call them not using the vehicle.

 

You can use the vehicle. There is some sort of problem with the OnStar.

 

Thanks to all. Left message with dealer service. Plan to contact OnStar later today. Vehicle seems fine otherwise

 

OnStar attempted reset; didn’t work. Several OnStar functions not working. Scheduled for Dealer Service.

 

GM is having some issues it seems with the OnStar module right now. This TSB was recently posted for many of their 2025 and 2026 vehicles, Ultium EV's and otherwise. For some reason Lyriq isn't mentioned (nor are 2024 model year vehicles) - may be a miss.

 

Spuds exactly like what’s happening with my Lyriq.

 

Yes, anything that had the OnStar module get stuck will result in those same problems and things not working. Do you just need a software update or do you need a new module, that is unknown. Let us know what the dealer works out to resolve the issue for you.

 

Will do, unfortunately, service date is Tuesday September 23rd.

 

Is that solely because of the dealer's schedule, or is your schedule also partially responsible? Nearly 3 weeks is unacceptable.

I can usually get an appointment within a few days to a week - including getting a Lyriq loaner. Concierge service to boot (they deliver loaner to me, take mine in. When ready, they reverse the process.
