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?

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:

    • Okay boys and girls I put a bottle of this in Dizzy the oil burning guineapig after a tank between the coil and plug service of the #3 hole and near the end of the first R&P 5W30 attempt. As a note I did a two R&P oil changes back in October of 2025 with little effect. Granted they were 1K mile a shot oil changes so.... Then followed by fourteen  1K mile changes of Mobil 1 Euro 5W30 FS. Also ineffective.    Anyone who has followed the adventures of Dizzy may remember that to put the oil on the full mark of the published nominal 5 quart change I withhold about a cup of oil. That over the last 50K miles the P0420 light has been a frequent flyer, sometimes three of four a day. And that even on 93 octane fuel she registers some KR even in moderate conditions on favorable days on slight inclines. Lastly when giving her a kick in the pants, something done about once a week, she looks like a diesel with the pump turned up. 😬   After one bottle and over the last 500 miles of a 3K mile OCI, of the first oil change I dropped the nastiest looking oil ever in her history. That's saying something as  you will recall I have used AutoRx, HP EC30/40 and a few other harsh solvents in her before including the GM top soak twice. This was syrup. Black stinky, inky syrup but the filter wasn't all that bad.    On the second fill I had to use the entire 5 quarts to reach the full mark. That was unexpected! The ignition KR is completely gone! Even at 99% engine load. MAP is much lower. Level road is now 9.8 instead of 12.5. Fuel economy is remarkably higher and for the first time since her earliest days she will spin to 6500, more than a thousand higher with out laying down dead. Yes, the coil and plug had something to do with that but remember the first 2500 miles after that repair on the first change it was same ole same ole Dizzy. Seems we have top rings that are somewhat functional again. P0420 code only comes on now if run in town for more than an hour of stop and go. On the open road it goes weeks without a incident. Perhaps it is cleaning the cat on the pass through?  Fuel Trims have improved as well. Nothing not to like.    To early to say about oil economy but the changes to date in the operational aspect is remarkable. I can't think of a worse case than Dizzy.... It's already paid for itself in a few tanks of fuel with the mpg improvement.    @OnTheReel, I'd say if the Jeep didn't respond perhaps there wasn't an issue to respond to.    I've run the Red Line SI-1, AMSOIL fuel cleaner, GUMOUT and Techron all in this SUV without any such results. Color me impressed. I'll be running out my supplies of the list mentioned and moving on to the Valvoline R&P Fuel System Cleaner.     
    • Hey Chuck !!Thanks for the all the info I'm an old fart and I have everything I need for the oil change at home,minus flexibility .... and I’ve been doing my own oil changes for 40 years. I just didn’t want to end up without a crush washer or with the wrong one in my stash and have to walk to the auto parts store, lol. I climbed under the truck to check the location, and man, it’s going to be the easiest oil change and filter swap in the last 40 years—right up there with my 2014 Mitsubishi Outlander 2.4. No mess, nothing to drip on—just perfect. I’ve got one more free oil change to use, and then that’s it with the dealership!
    • I think this subforum was created for the new generation pickup trucks (2027-) with the 3.0 but I don't think it's a big deal either way. There are probably 2027 model-year specific changes for the SUV's too.   I was just curious if you had issues with your 2025 3.0. I'm still under 10k miles on mine and fingers crossed I don't have thrust bearing issues. I'm guessing not, since you're willing to buy another one! It's a good engine minus one or two manufacturing whoopsies.
