Problem with Trailering App

This thread was started a while back.  https://www.gm-trucks.com/forums/topic/244615-2020-silverado-z71-rst-screen-black-out-on-selecting-trailering-app/.  I didn't want to respond to it because I wanted owners of other vehicles to respond.

 

After working fine for 2 years my 2020 Sierra is having the same problem.  There are times when the app won't load and just has a black screen.  It started a couple of months ago and is happening more often, but not every time.  It doesn't matter which trailer I hook up and it happens even with no trailer (in that scenario it is supposed to load and say there is no trailer connected.)  Even though the app doesn't load I still have lights on the trailers.

 

Messing with the plugs doesn't help.  Once it in black screen mode it doesn't load until the truck is shut off and restarted.  Sometimes that works and sometimes it doesn't.  On a trip last week I tried restarting repeatedly and finally gave up.  I towed the boat to the ramp about an hour and a half away without it working.  After fishing for about 8 hours I got in the truck to leave and it loaded right up.  I hadn't touched a thing.

 

Has anyone been able to figure out what is going on?  I had the truck at the dealer on Saturday for the state inspection and mentioned it to them.  Unfortunately they are working with a skeleton crew on the weekend and don't do diagnostic work.  They did tell me that they had never encountered the problem before.  That could be an issue because it doesn't act up every time.  I don't want to drive there and have it come right on so they don't see the problem.

I have 2020 Silverado with the trailering app and *exact* same thing is happening for me since delivery. When screen is blank, have to shut off truck, open driver's door, and leave truck off for 15+ mins to reset. There is a TSB out that says to reset Infotainment System to factory default, and show customer how to do this in case it happens again. I've had service 3 times for this where different software was reloaded, but no improvement. Dealership tech even opened a tech case with Chevy, but response was to reset to default. I opened a customer case and was told to try a different dealership, no improvement with their help either. Bottom line, I was told it is a software anomaly and there will probably never be a fix.

That is not good news.  When I bought the truck I was also considering the RAM.  I had listed pros and cons of both and the trailering app on the GMC was a factor.  If that isn't going to work I may start wishing I had gone with the other brand.

 

How do you reset the Infotainment System?

How do you reset the Infotainment System?

On the radio display, go to settings, updates (I think), and then Return To Factory Settings. You will reset all truck settings, delete phones, and delete all programmed radio stations.

Does that actually fix the issue?  I've seen other posts from people saying that procedure doesn't help, then you're stuck with redoing all of your setting...

No, reset to factory default settings is not a permanent fix, just the only solution GM had for several years. But, a software update has finally been released and it did FIX the blank trailering app on my 2020 - have not had a blank screen since software update. Check out my post and also download the related TSB:
