2024 Cadillac Lyriq No Longer Works w/ MyCadillac App or OnStar

Question

I have a 2024 Cadillac Lyriq that has stopped communicating with the MyCadillac app. The remote start features no longer work. OnStar is not working correctly either. I have tried a soft reboot of the infotainment. I have tried a hard reboot by disconnecting the 12v battery. I have tried uninstalling and reinstalling the MyCadillac App. I contacted OnStar and they said they would escalate to level 2 support - but no one has gotten back to me. You can see in the app that it hasn’t successfully communicated with the car in 6 days.

What are other things I can do? I feel helpless and without any support. It’s deeply disappointing having a 2 year lease on an expensive vehicle that is less than 3 months old and doesn’t work as advertised.

I have the exact same problem right now, with my brand new Lyriq, have been on the phone with OnStar 5 times and they still keep saying the same thing, tech will get back to you in 3-5 days. 7 days later they still say 3-5 more days??? Did this ever get resolved for you and if so how.
