I'm having a similar sounding issue with my 2021 Sierra 1500 with the LM2. Wondering if you got this resolved and what the solution was. TIA

My 2021 Sierra 1500 at4 LM2 hasn't been updated since August 2022. Went to update today, connected to WiFi and tried to update. Will attempt to search for update for about 10-30 sec. before saying connection unavailable and prompting me to check the internet connection or switch to a new connection. Important to note, WiFi connection works fine outside of the update search - I am able to stream the radar, etc. Have had the same issue in 2 different '21 Sierra 1500's (LM2 and the 5.3). I've tried switching WiFi networks, switching WiFi bands, mobile hotspot(used to work), forgetting networks and reconnecting, restarting the truck, etc. I feel that I've tried everything short of restoring to factory defaults or taking it to the stealership - neither of which I want to do. Looking to see if anyone: 1. Has had or heard of similar issue and how it was resolved 2. Has any ideas if this this issue is on my end or GM's 3. Knows where I can find the patch notes/update logs to check latest available for my truck. TIA

Gonna leave this here... Make sure your service center has read the link below. If problems continue after this I'm going to take advantage of the used car market and take some profits. https://gm-techlink.com/?p=14824

Can you please share the photos?

Same thing happened to me today for the first time at 4029mi. Crank timed out, I got out checked for any blatant leaks, saw none, tried again and it started right up. Other issues I've been having are a engine light for abs system (only experienced one during heavy rain) and camera system wouldn't work one day. Bought the truck a month ago and I love it, I'm just nervous about the issues it's been having... All intermittent and seem to be electrical.
