This is happening on mine too.  I’ve noticed the Auto Stop feature is not working either when I have these issues, along with making changes to the settings on the infotainment system.

 

Pretty frustrating that this wasn’t caught in testing.

The start / stop feature has a lot of parameters to meet before it’s active. If the engine isn’t at temp, or the battery is not charged enough, or the ambient temperature is too low, it won’t activate. On really cold days mine never shuts down.

 

I too have noticed a few funky things changing on the infotainment, especially the camera views. But that sure doesn’t annoy me like the “trailer disconnected” every 3 seconds though.

Same issue here. Less than 600 miles on 2019 1500. It's at the dealer for the second time in less than three weeks (2 of those weeks it wasn't driven). Took it out in the snow five blocks to grab a bi

GM has released an updated program to fix this issue on March 1st, any programming done before this was not the final "fix".

They must have put the intermediate or non-final program on mine last week. It’s been a lot better. I was still getting the error yesterday in 5 degree weather but today at 10-15 degrees it was fine. Usually anything below 20 was a guaranteed error-fest. Anyway, I’ll be making an appt. next week to get it done. I was sort of waiting for any number of people at GM or the dealer to call me but I guess they don’t give a rip.

Truck is at the dealer now
They said there was a recall for Rear parking assist and SD card navigation problem
Do you have any idea what the official name of the updated fix for the trailer disconnect error is

I got the call today from Dealer, I am going in on Friday to get the updated program.  Will update everyone after that.  If they actually are desensitizing the systems and it makes any of systems perform less, I will be taking my truck back in to have them fix that issue as well.  Stay tuned.....

#PIT5648B: Trailer Disconnected Check Connection Message on DIC Without a Trailer Connected (Reprogram the Trailer Lighting Control Module K68) - (Mar 1, 2019)

 

With U1D - Advanced Trailering System 

 

Some customers may comment on a "Trailer Disconnected Check Connection" message being displayed on the DIC without a trailer connected,  message shown below.  In addition to this message, there may also be the following messages depending on the vehicle content:

  • Rear Park Assist Off
  • Lane Change Alert System Off
  • Rear Cross Traffic Alert Off

This condition is more likely to occur with colder ambient temperatures.

 

This concern could be caused by the Trailer Lighting Control Module software.

Correction

To correct this concern, reprogram the Trailer Lighting Control Module (K68) with the latest software available in Tis2Web.

 

Additional information for false trailer detections:

The Trailer Lighting Control Module monitors the trailer tail lamp, trailer Rt stop/turn lamp, and trailer Lt stop/turn lamp circuits to determine if a trailer is connected.  If the Trailer Lighting Control Module detects enough of a load on any one of these circuits, it may determine that a trailer has been connected.  If moisture/corrosions/etc. gets into either the trailer receptacle, or the Trailer Lighting Control Module connector, or if anything is left plugged into the trailer receptacle, like trailer adapters with built in test-LEDs, it may cause the module to think that a trailer is connected when there actually is not.

  • Inspect and remove anything that has been left plugged into the trailer receptacle, such as a trailer adapter plug. 
  • Inspect the following areas for any moisture, corrosion, etc.:

 The 7-way / 4-way trailer receptacle X88, located at the rear bumper.  

The chassis harness connector X1 that plugs into the trailer receptacle X88.

 

The Trailer Lighting Control Module K68 connector.

 

Clean and dry, repair and/or replace any connection issues which have moisture/corrosion present.  

 

This PI maybe converted to a bulletin shortly.

Nice, at least the frustrating part is covered. But read closely, they are NOT fixing the problem, they are covering it up. There is still a mild short to ground somewhere. Beware!

The feature I would expect to no longer work might be the trailer disconnected alarm...

 

I scheduled an appt with my dealer to have the programming done... not too hopeful because the last few times it has been in for this they either leave it inside where it is warm or it hasn’t been cold enough. The service tech said that if their scan didn’t find anything they wouldn’t do anything to it. I pointed out that this isn’t a code issue and could they just right the number down from the above and check that specifically. I can even show them a video of it failing. He said that doesn’t matter, no codes in his fancy computer equals no work done unless I pay for it. I had to argue with the guy for him to even bother writing the PIT number above down for the techs to look at. 

 

GM is the worst. Everyone I talk to about this truck gets an earful about how terrible this has been. Even though GM probably won’t notice the sales difference I personally swayed two people to buy a new Ford instead of this GMC specifically because of how this has been handled.

That is BS, there is a update that is free and covered under warranty. I had mine done today. Mine had for some reason been working ok so I saw no difference. This update PIT 5648B is an update to the update PIT 5648A. The only difference is a bit of programming to ignore amperage on the trailering system.

Unfortunately, A manufacturer is never going to just buy you out.  You will have to get a lawyer and press the issue under lemon law, if your particular case qualifies for it.  I live in CT where the lemon law is two years or 24,000 miles.  “A reasonable number of attempts to fix the same problem”, which I’m told is four.  The “senior advisor” said they “never attempted” for fix it because there was no fix.  Which is B.S.  You can’t just tell someone it’s broke, we can’t fix it, wait MONTHS, too bad, so sad.  They will lose in the end.  They will eventually have to buy the truck back, minus some formula for mileage AND pay for my lawyer fees (part of the law).  It doesn’t happen overnight, but it will happen.  It’s really too bad.  This is my first GMC, it’s a beautiful truck and I love it otherwise, but this has been a horrible experience!!

I don’t even see how this is even a software issue. This only happens in real cold temps.  How do cold temps affect software or amps?  This sounds like hardware issue.  When its cold, things contract, when hot, they expand.  It’s seems like a connection issue.  When it gets real cold, a connection somewhere is probably contracting and squeezing the connection to screws with the contacts which send the signal wether or not a trailer is connected.  When the temps are warmer, the connection expands to normal and the contacts are seated correctly again and we get no warning pop ups.  This “fix” almost seems like they are disabling something in the software so the pop ups will stop popping up.  This actually doesn’t fix anything, only hides the problem.  Only my theory, but makes sense, no?

      AFM Experience

      By Atlas · Posted

      When I had a Bumper subscription for a few days when I needed to run title histories on cars I was looking at, I decided to look up a few of my old/past vehicles.   My 2015 Silverado was still actively registered and it last sold in 2024 with 160k on the clock. No idea if that's on the original engine but someone's keeping it on the road or the original AFM stuff is still going.   It used 0w20. I remember feeding it Mobil 0w20 AFE for the first 30k of its life on <5k OCI's.     Edit: Just did a nationwide search on Autotrader for 2015-2025 Silverados with 5.3's and sorted by highest mileage first.   357k 352k 292k 291k 290k 277k 271k 268k 266k 259k 256k   High mileage on a modern 5.3 doesn't seem all that uncommon, but that's just searching mostly dealer ads on Autotrader. FB Marketplace has all kinds of high mileage 5.3's going back to 2007

      Bridgestone vs Goodyear tires?

      By Chuck FB · Posted

      I can't say I have ever heard of someone getting that type of mileage out of a set of tires even though they rotated on a regular basis but without a doubt if the front end gets wear and those tires are no longer able to track straight it scrubs them off, and driving style and road surface make a huge difference as well.    However that is not what prompted me to comment as it was the new tire theme of sitting in storage waiting to be used scenario. I am sure some tires can last for quite a while in storage if its not too warm and out of the sunlight but unfortunately some tires the way they their rubber compound is formulated they can age and dry out even in a reasonably decent storage location. My brother ran into this maybe three years ago when he was looking at the tires that were on his dually truck and a combination of wear on the rear ones and noticing that the front tires had some cracks around the sidewall of the tire not far from the bead but he had replaced only the front ones not long ago with 2 of the remaining 6 he had left from the initial two sets of takeoffs he had all bought at the same time .... 10 years ago ! ( the years fly by, a truck that only gets used a bit to haul a camper during the summer and sits in a shed for a large part of the year ). That second set of 6 tires, two he had put on the front prior like I said and they had very little wear but those cracks were now present. So we go into the shed where the other 4 tires had been stored all this time and every one of them had the same cracks in the sidewalls and so in the end it amounted to throwing away 6 brand new but 10 year old takeoff tires into the dump that he got a deal on at a tire shop because they aged out. They were a Ford factory equipment BFG tire and those tires did not age well compared to some tires I've seen far older then that and did not show that type of aging. True, they always say up here anyway that 7 years is sort of a limit for age by rights, we don't have the intense prolonged heat that many of you have down in the states that just cook tires and depends on where the vehicle sits when not in use. GB, another words maybe had you bought a set of tires to store it would have been fine as long as you used them up fast enough but there are no guarantees when it comes to rubber, tires or of that other type stored in some guys wallets 😆

      Open Door Chimes When Key is Out

      By Head South · Posted

      2020 2500 HD...I had some trouble getting the key into the ignition switch but went in fine after applying some extra effort. Since then, the door chimes when open when the key is out of the ignition. Also, when I lock the doors with the switch on the arm rest, the driver door locks but then unlocks. (I can lock everything fine with the fob) The message on the little screen displays the "Engine Hours"...kinda weird.   I'm guessing something happened to the ignition switch and it thinks the key is still in there. I unplugged the batteries for 20 minutes, no change. There are a number of videos on YouTube but nothing I can find that address this specific issue. Ideas appreciated, thank you.

      Front End Rattle

      By AndrewF · Posted

      Looking for help troubleshooting a metallic like front end rattle. Figured I’d see if anyone had thoughts before I schedule an appointment with the dealer.   The rattle is fairly loud and occurs primarily when the front driver side wheel hits a bump, even fairly minor road seams. Sometimes does it when the passenger hits a bump but I don’t believe when the rear hits. Rattle still occurs when foot is pressing brake peddle so I think that rules out the caliper rattle I’ve read about. I’ve also checked the running boards and they are tight.   Most noticeable at slow speeds.    Any insight is appreciated.
