Infotainment Screen Black When Using Remote Start

Recommended Posts

2020 Chevy HD with 9K miles started doing same thing as discussed. Remote start works, but upon entering vehicle, apply brake, and hit start button, everything turns on, EXCEPT infotainment screen. Have to shut off vehicle and restart. After 3 days of doing this every morning, my battery was dead. Dealer picked up vehicle. Ran some tests, all was good with alternator and battery, unplugged battery for awhile, performed regular maintenance and service that was due. Truck has been fine for a week now.

I think the OTA Update addressed this issue, along with several other software glitches.  I just did the update this evening.  Only took about 10 minutes.

so it's finally available?


EDIT: checked yesterday. my truck said no update available. I think it said last update was sept

I joined this forum because of this post, but I wanted to say my truck started doing this within a day or two of getting an oil change at my dealership. Has anyone gotten the update OTA recently? I just checked on my 2020 GMC Sierra 2500 AT4 and I got "No Updates".


@kylant did your truck ever update?

Quick update and the madness continues:

  • Reviewed v150 upgrade on my radio successfully on Wednesday, February 10, 2021 - all functions now work, I can remote start my truck and the radio works, SiriusXM works again, and my WiFi doesn't stay on beyond a couple minutes
  • Talked to my dealership and while all seems well on the surface, there was a fault code they could see internally on the radio and advised it should still be replaced
  • Radio Module is being replaced under warranty on Friday, February 12, 2021

      I purchased a 2021 Silverado Z71 in April, and I love it, but an odd quirk with the infotainment system. Each time I get in my truck, with the same cell phone I always carry, I cannot make a voice activated call for up to 5 minutes.  The response is always "please wait, I am loading your contacts".  Why does the system load my contacts each time I get it the vehicle?  Is there any way to have it store the contacts and not upload every time?  Is it supposed to do this?

      When I set "maximum start-up volume" to a good level, it will hold for a couple of starts.  then it reverts to a very loud start-up volume.  Radio blasts loudly until we turn it down.  Reset maximum start-up volume repeatedly but will not hold.  always reverts to loud start up volume.  service department has not heard this problem, but a friend with a 2021 silverado has the same problem, exactly.

      Looking at getting the 20" Factory Reproduction Style 59 wheels in black and would love to see if anyone has pics of them installed on their trucks.

      Good morning
      This is more of a FYI after a bit of runaround with GM/Onstar support.
      I'm on the 2nd week with my new '21 Sierra Denali. The issue I'm having is when accessing the "Apps" module in the infotainment system. When I try to open it I'm presented with a connection error asking me to check my network settings, available data, or connect to another WiFi (attached screenshot). After checking everything, connecting to multiple WiFi, etc. I called GM/Onstar support and after being passed around I ended up talking to a support tech that knew exactly what the problems was. This issue isn't related to the vehicle's setup, but apparently related to something that Amazon did with their service(s) that is causing the apps module to fail to load as it checks for status upon loading. This issue started popping up around 2 weeks ago and, according to the tech, affecting '21 Sierras (and later '20s). There is no ETA on resolution to this, but was informed that engineers are aware of the issue has there is an active service ticket for it to be fixed.
      Hopefully this post will help out any other owners having the same problem as it's not something that is readily known to GM/Onstar support.
