WiFi on but no internet connection anybody got an answer?

Same issues here....

Bought a new 2024 Hummer EV. Drove it home to find that google was unable to connect to the internet. I can connect to the vehicle's WIFI with any other device, but they all show no internet access. I've called OnStar five times as well. They have opened a "case" with a level two technician looking at it. They have sent signals several times with no resolution. One even promised to follow-up via email with me to see if it was resolved, but no message ever came. I originally had access to use my Supercruise feature, but now that has since turned off. 

The customer service here is embarrassing for a company of this size. GMC and OnStar love to point fingers at each other. The dealership wants to keep my vehicle for days because they only have a couple hummer certified techs that can touch it! 

Overall, I'm beyond frustrated to purchase something brand new and have to jump through hoops just to get it to work the way it was advertised. This issue seems large enough that a recall should have been made.
