Hummer EV is broken, no one can figure out why

To sum up the post, if you are used to accessing your vehicle controls from your phone and sending remote commands - do NOT buy a Hummer EV. 
If you like watching shows on your car infotainment screen while charging - do NOT buy a Hummer EV. 
if you like checking the app to see how much charge you have on your parked EV - do NOT buy a Hummer EV. 

Hummer EV is broken. On Star doesn’t know why, Dealer doesn’t know why, GM doesn’t know why. Is it Onstar? Is it the Cars software? Is it the Hardware? No one has an answer, and no one cares. 

call onstar and they lack the technological know-how to trouble shoot anything that isn’t a “reset”, the dealer doesn’t have the tools to check if the hardware is working and will just tell you to call GM or update the software. GM, well Goodluck getting a hold of them. 

the sad part is my prior EVs from 2012 and 2018 from Tesla and Rivian had very reliable app connectivity to issue commands. My other car, a Lucid, even lets you schedule your service from it. Never an issue with speaking to your vehicle. So why can’t a legacy car maker like GM figure this out in 2025? On a $100k EV. 

Hulu app? Doesn’t work, just keep hitting retry. Wi-Fi hotspot? Doesn’t give you the option to turn on data. How much charge does my Hummer have? app says It’s been at 72% since I picked it up from the dealer. Lock/unlock your car or any other remote command? Negative.

do yourself a favor, if you want the tech to work, buy the car from a startup, not the guys that retired the H1 Alpha or produced the gaudy H2.
