Infotainment Screen Black When Using Remote Start


Recommended Posts

I have less than 300 miles on my 2020 GMC Sierra 2500HD. I have utilized the remote start feature on my fob 3 times so far. Each time, upon entering the vehicle, I place my foot on the brake and push the start button to bring it up to life. Everything works fine, with the exception of the infotainment screen. It remains black, with the exception of displaying the rear camera view when I back out my driveway. Once back in drive, it goes back to black. I have to park the vehicle, turn it off, and then re-start using the vehicles start button to bring the display back on. Anybody else having this issue?

That’s odd. Sounds like a software glitch to me.

I have the same truck. When I remote start it, the screen stays black. Once I get in, the GMC splash screen comes up. As soon as I hit the start button, the radio comes on instantly.

Thank you all for your info. I went into SETTINGS and tried to search for an update, but it said none available, and I also went onto ABOUT and it shows a BUILD NUMBER with a bunch of letters and numbers (I'.m assuming its version 148, as part of the numbers are "U148.3.4") with a date of Sep 12, 2019. I also tried pressing the HOME button below the screen, and it would not bring the display to life. Results are the same if I use the smartphone app to start the engine. So I guess its a glitch. I'll wait for something else to creep up before bringing it in.

Well, this morning I got up bright and early to go take her to her first car wash. But she would not budge. After repeated tries to start the engine...just a click click click and multiple error codes. I called GM Roadside. The tow truck arrived and jump started it. I drove straight to the dealer to address this issue and the infotainment screen issue noted at the beginning of this thread. I just picked her back up from the dealer. They found that the 12 volt battery on the drivers side failed the "GR-8" test, while the battery on the passenger side was good. Replacing the battery also remedied the black infotainment screen upon remote start up issue!

Interesting way to get the infotainment system fixed haha. But weird that your truck wouldn't start with 1 good battery. I assume everything was covered under warranty. I remember reading in one of the threads that a dealer would not replace a bad battery in a new 2020 HD diesel with dual battery system... I think it was in one of the trailer light threads.

 

Good that they could fix everything in one day on a Saturday.

Yes, and if you don’t restart the vehicle to reset the screen, overnight my batteries drained completely dead!  Can’t even jumpstart it now, currently trying to put a little charge into the batteries to try boosting again...

      I have a 2012 Suburban, owned since new.  Yesterday the key fob / remote / keyless transmitter stopped working.  It stopped, then worked a couple times to unlock, then quit completely.  I assumed it was a bad battery (10+ years old), so I replaced it with a new battery, still didn't work.  I have the second remote that's only been used a couple times when the keys were "lost", and it doesn't work either.  No response from any buttons.  I checked the batteries in both, and both batteries are at 3.3 volts.  I pulled the DSM fuse for 5 minutes and then disconnected the vehicle battery for 5 minutes, no change.  I have tried holding the remote right next to where (I think) the RCDLR is in the left-rear pillar, still no response.  The TPMS system works fine, reading all 4 tires correctly with no errors.  I hooked up my ODB2 scanner, and it doesn't show any codes.

      Do I have two dead remotes?  Or has the RCDLR partially stopped working?  I called the dealer, all they said was "buy a new remote, your two remotes have died".  I asked, why would an unused 10 year old remote die?  No answer, just come in and buy one.  I have no faith in my dealership's service department based on previous repairs unfortunately, so I thought I'd ask here.  My local locksmith will attempt a re-sync for $50, but they said if they're both not working it's not that.  Unfortunately this year model won't allow the user to add or reprogram a remote.
       
      Thanks in advance for any ideas of what to try, or what might be the issue.

      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.
