That sucks. I had mine do similar. Once it was at the dealership, they installed the update via direct line.

I turned off downloading OTA's in the background and downloading OTA's via WIFI. Not gonna chance my truck being bricked again from a hanging OTA download.
 

Well took the truck to the dealer yesterday to have them reflash the truck, well needless to say the truck doesn’t want to stay running, they kept the truck till Tuesday when a diesel tech can look at the truck, joy only 10,000 miles on it.

So you must have the 3.0 diesel. Hopefully the DEF and emissions system is not a problem for you. My 2020 AT4 3.0 had emissions system problems so bad they couldn't fix it, so I traded it off for my 2023 AT4X.
 

After the latest update, my infotainment screen will randomly reset and restart. Anyone else experiencing this?
 

I gave up on the (x)! Have taken it in twice, now they want me to bring it in and leave a few days so they can talk to GM to figure out how to make it happen. Risk ain’t worth reward reading this thread. Seems GM is making things worse with updates. Latest one I have to turn on auto headlight every time I start. Seems drug and alcohol testing at work has gone away at GM😂😂

That happened to mine the day before my truck was bricked. I didn't realize I had an OTA downloading in the background, which got stuck at about 50% the way through downloading. Not sure if this is why my infotainment system crashed completely while driving, but since the next morning my trucks entire electronics was bricked and it wouldn't even start, it seems logical the stuck OTA update download may have been the cause.

I had to take the truck to the dealership, who were able to force the update via hardwire in their shop. They also replaced the battery saying it was charging slowly - i.e., the battery failed their 60 minute test. Upon receiving my truck back (2023 AT4X 4.5 months old), the infotainment system was slow and laggy, and my bluetooth connection with my phone for music kept stopping, but it has now settled in back to normal.

All these OTA's seem like a hit and miss venture - since these trucks run off a computer system, if the computer system is not working properly, the truck may be bricked also.
 

Watching this thread. I have a 2022 AT4X with the “AT4” image on the gauge cluster at startup. Always perplexed me. I’ll check my manufacture date later.

Reading some of these comments makes me nervous about having the dealer do the software update on the gauge cluster.

I may wait a bit to see if this eventually turns into an OTA update with better reliability.

Cheers all, hopefully some of you get your troubles worked out fast.

If anyone has any new updates that would be awesome to hear.

I had my cluster updated (2022 AT4X) and everything went smoothly. Somewhere in one of these threads, someone shared GM details about the appropriate way to do this. A key part was power supply to the truck. If power shuts off mid-update, it will brick the cluster. GM actually specifies what they need to do, but the tech has to follow those instructions. For this reason, I don’t believe it will be on OTA update (I am thinking it is updating cluster firmware which may be more sensitive than the typical OTA update things).

I have had several OTA updates that have been really good. Someone mentioned above about auto Hi beams staying on between starts. At some point, that went away and required setting each time. Recently, it returned after an OTA. So, now it works like a lot of us prefer.

Super helpful information, thank you for this
 

Anyone else try this dealer Service Bulletin (Bulletin No.: 22-NA-253) yet -- "Subject: Cluster RPO UDV 162.1 Software Update – Multiple Updates". I have a 2022 AT4X (pre-AEV bumper) built in 9/2022.

Just curious if anyone else tried this without issues?
