I have a new to me 2020 GMC Sierra 1500 Denali with 23K on the odometer. I set up various profiles for the different trailers that I tow occasionally. Today I was trouble shooting the lights on my small cargo trailer and the trailering app failed to initialize. I let it rest for a short while and tried again but the problem didn't go away. The third time the display said not available, try again later. 

 

 

Any thoughts anyone?

6th try was the charm. The trailering app just started working all of a sudden. There must be a electronics gremlin lurking in the background just waiting to mess with my truck. I hope this is just a one-time event.

Mine can be hit or miss.  I haven't towed in a few months but I recall it doesn't do a heckuva lot anyway.

I have 2020 Silverado 1500 and my Trailering App is also intermittent. I've been to two dealerships, center display software has been reinstalled multiple times, I opened a customer service case and even had a tech service case opened that simply told tech to reset console to factory defaults. Unfortunately, nothing improved the App, it's hit or miss. I'm still under warranty and will be taking it back again soon. One tech told me it is a software anomaly that will probably never be resolved.

That's discouraging news. It's like they are in so much of a rush to get this to production that it's not thoroughly tested before hand. Then once it's out the door they are on to bigger and better so it's left in the dust.

It continues to be very sporadic. Sometimes it works and other times it refuses to initialize. I have a towing job this evening. Hopefully it will work then. 

 

I like having the profile of the different trailers that I tow because it will remember the brake gain settings and remind me to use the tow/haul mode. The light test feature is great as well.

 

I love the way it's integrated into the blind spot camera so when I turn on the turn signal that sides blind spot camera come on automatically. It sure makes towing a lot easier.

 

I would just like it to be reliable and not be so hit and miss.

I have had the trailer app not start a few times, I just get a blank black screen when I go to that screen. probably works fine 95% of the time

I hear ya. That's exactly what mine does. The local dealership is aware of the problem but didn't volunteer a solution. 

Also, I get a message sometimes when I go to engage the cruise control that says 'adaptive cruise control not available' . This is a little frustrating especially since I use it all the time, even in town.

It would be nice if this problem would get fixed, I have had it for the life of my truck so far.  Hampton Chevrolet has replaced the screen, same day I came out after shutting down and still had the problem???? It works when it wants to. Updates anyone?

No solution either, for my 2020 Silverado. Trailering App randomly does not start (blank screen) whether connected to 7-pin travel trailer or 4-pin fishing boat. It's about a 50/50 chance it will work. Dealership asked me to bring truck and travel trailer in to check and reloaded some kind of software. But, just like you said, I started truck the next day with trailer connected and app screen was blank.

My truck acted the same way for a short period of time but for the past several months it's worked flawlessly. I just finished a 2,600-mile trip pulling a cargo trailer and everything worked correctly. I hope this problem has corrected itself.

    • Hey guys, sorry for the confusison about this. This wasn't my experainnce, it was copied and pasted fom the net. 
    • The problem with failure rates or increase failures are there’s people who don’t have a problem. What are you doing wrong they say. We had 4 5.7 GM diesel’s in the family when they came out. One was flawless. My uncle who happened to be the most abusive. Early rotary engines were known to use oil. I abused my first car so bad in six months I replaced the clutch, transmission and rear end. It didn’t use oil. My brother in law has a 2013 Tahoe and an older Yukon. The Yukon has 280K miles. The Tahoe around 175K. He runs them to about 300K. If his lifters fail before that time he would consider it a failure. My Hondas, I know people hate it when I mention them. Identical engines. One with cylinder deactivation one doesn’t have it. One shudders when the eco light goes on or off. Cylinder deactivation. But wait! According to the web. It can happen with lock up too. So now people in the know are changing the oil and transmission fluid more often. Then you read it could be a programing issue. So what do you do? There’s lots of money involved. I see three ways to deal with it. One only works if you don’t drive lots of miles. Lease, never get out of warranty. Or only buy older vehicles with a good track record. They all have bad runs. Usually when there’s a change. Even Toyota and Honda. 
    • Question @diyer2 on this line if you please. Are you saying the shudder is the system turning on and off at the frequency of the shudder? Guess I'm asking if you are saying you have seen it do this with the bi-direction scan tool in graph mode? If so have you been able to discern the 'trigger'. Something is telling to cycle rapidly.    My truck just started doing this recently. 197K on the clock. My response has been M5 anything under 55 mph. I treat it like a lugging stick shift. Gear down and let it spin a bit. Engauge M5, then tow mode and then M6 lets the trans stay in 5th but the AFM is active. Smooth like Skippy.    My thought was that as a machine ages the friction gets lower and as the system is load based, the lower friction would allow it to turn on at ever lower rpm until it reaches the lugging point. And yes I am ignorant of any minimum rpm requirement for the system. If you know that would be useful information.    As you know I run a Scan-Gauge II which allows me to watch the On/Off of the signal to the VLOM. While in the shudder mode I'm not seeing is cycle at that frequency or at all for that matter outside the triggers @newdude posted a few years back. Now is it possible that the refresh rate isn't fast enough to catch it? Maybe. It is why I asked my first question about graphing and trigging parameter.     As we have observed from members here the failure point is all over the map miles wise as you note yourself in your opening post. That by itself begs a few questions like fellows that comment on these lifters failing even after the system has been disabled. Long after. 😬   https://www.enginelabs.com/news/tech-tips-replacing-ls-active-fuel-management-lifters-with-melling/   The Gen5 lifters operate the same as the LS versions. In fact they are the same lifter.    https://www.enginelabs.com/tech-stories/sorting-out-gen-v-lt-lifter-failure-with-a-simple-valvetrain-fix/        
    • UPDATE 2: Steering wheel control backlights and control of the cluster can supposedly be achieved by adding a wire to pin 20 of the cluster and tapping it to pin 2 of the main clock spring harness. I'm going to give it a shot - will update  
    • GM Global A pickups 2019-2022 can do OTA programming for the radio.  GM VIP (GM Global B) can do OTAs for almost every module on board.  So a 2022.5 and newer pickup can do OTAs for recalls like the 2.7 fuel flow recall.  EVs get OTAs that improve one pedal driving, radio issues, HVAC issues, updated battery management software, etc.     So age of the vehicle/what GM electrical platform its on will alter what amount of updates can be pushed on OTAs.
