PIT5793- No wifi, apps, internet connection...

[Ryno12 92]

I had the exact same issue. Same messages on the screen, had WiFi but no internet connection, apps that require data didn’t work, etc.
I was on/off with Onstar a few days. They had finally escalated my issue to a higher level of tech support.
It was getting late in the evening & I told them I was done hanging on the line with them. They said they were going to continue to look into it & they would call me the next day to further troubleshoot the problem.
By midday the following day, my problem was gone & they never called me back. Haven’t had an issue since.

Did they seem receptive to you knowing about the fix already and having the TSB #? I told my guy all about it and he’s like “I don’t need that, they will just see what it does and then see if there’s any TSB that describes your issue.” Um, there is and I’m holding it in front of your face.

I took mine in about a month ago and the service guy gave me a copy of the  PIT5793.  He said GM was working on a fix and that he would contact me when one was avaliable. He called me on Tuesday and scheduled me for Friday.

Went to the dealer this morning for software update. I was there for 40 minutes and was back on the road. The problem with the app and connection appears to be solved.  No more Connection Issue.

Mine is there now. Haven’t heard back yet. I basically had to convince them there was a TSB for it and they still didn’t seem to care what I had to say. Guess I will call.

Picked it up and all is well!

Amazon app problem? I’m not exactly sure what that’s referring to, but whatever it is is not causing OnStar data usage to fail to load or preventing any GM app from downloading or preventing my app from connecting to my truck.

All those issues were resolved with the radio update described in the TSB.

So glad to hear that I am not alone in this. Just bought a $66,000 AT4 and can't even use the apps. I called OnStar and they said to take it to the dealer. Called again and got someone else who acknowledged this issue and said a fix is coming soon. So, nice to know I'm not alone, at least. Sounds like "coming soon" has been going on for a while now.  WTH

The fix came out last Tuesday. A few of us in this thread (myself included) have received the update at the dealer and it is now fixed.
