Well, middle age has hit me hard. 

Same here. These are getting more and more complicated. But glad it was figured out.

Sounds like the system may not be recognizing the remote when you enter the truck. Have you noticed a "remote not recognized message" on the DIC?

I would probably go get the 2nd remote just to eliminate the 1st remote as the issue........

Dead remote battery. It may not think you have it. Try placing it in the designated key pocket then open/shut door. 

Bingo...I think. 
 

I put a new battery in the remote Friday. No honking since. 
 

Kind of shocked the battery in a one year old remote went dead so quickly but whatever.

Nope. Still doing it. 
So it's actually honking because it thinks that the remote is not inside the truck anymore.

so for instance if I have my truck running and remote in my pocket and I get out of my truck and close the door to go into the gas station it honks three times.

it's just one of those things that's going to happen with a keyless entry system.

could GM have done a better job as far as it correctly identifying if the key is inside or outside of the truck? of course, but it is what it is.

Just annoying how it intermittently does this despite immediately afterward, and without fail, starting right up with the push button.

Horn honks 3 times also if the remote gets left in the vehicle.  Mine does this sometimes as well when I leave work and I think I have figured out why.  When I get to the truck I open the back door first to put my duty belt in the back seat and what ever else.  Then I open front door and get in, and as soon as I close the door I get the 3 honks which I believe is the "Fob left in vehicle reminder" and I think it does this due to the fact a door was already opened and closed with the Fob in range and it thinks I am leaving the vehicle and leaving the fob in it when in fact I am getting in the front seat.  I do not know if you are opening the back door first as I do or not, but I believe this is why mine does it.

This has been happening to me for

the last 5 days on a 2019 trail boss with 65000 kms. I leave my truck with fob in hand and about 10mins later it gives me 3-5 quick honks, like super quick. No idea why it’s doing it. Leave key fob in house, go out to investigate, trucks locked, no lights on dash like something is on. Yesterday morning I started the truck, went to back up Out of the driveway for work and my steering wheel was locked. Cycled off, on. Still locked. Another cycle, same thing.... locked. No lights on dash, nothing,  Everything else was normal.  Came home after work, started it and it was normal again. Had steering. No idea. Hate this truck

@AJMBLAZER did you ever figure this out? My 2020 is doing this when I get in the truck with the fob in my pocket, or in my hand. It's driving me nuts.

No I never did. However I swear it’s better now. Kinda wondering If one of the software fixes worked on it. 
 

Still annoying when it does happen.

Mine does the exact same thing. How do I turn that honking feature off?!

 

I don't care for the truck to remind me that I left my remote inside (even though I didn't, because I AM inside the truck).

You leave your fob in the truck at night?  Just wondering if it is honking because it thinks you are leaving the fob in the truck.  I know my truck and my wife's car will honk if you leave a fob in the vehicle and it is shut off or you get out of the vehicle with the fob and it is still running.  I wouldn't think it would be an issue when leaving, but if you came home at 5am and left the fob in the truck.

When you leave your key inside and close the doors it beeps 2 times, this one beeps 3 times and it's actually louder, even with your keys outside. I would have to disconnect the battery for a couple of minutes, then reconnect in order to fix the problem. Goes away for like 3 months then comes back.

      Oil Consumption

      By Chuck FB · Posted

      So speaking of oil consumption with my L8T as I just changed the oil yesterday and made the switch over to Amsoil SS 0W-40 from the Mobil 1  5W-30 Truck and SUV I just dropped out. 2900 miles on that oil as well as  68 hours on that oil ( so used to equipment with an hour meter and that becomes valuable information to compare with others as well ). Once again the oil use was so very little, I am going to say it dropped under 1/16 of an inch on the dipstick. No towing was done and this interval was from early spring until now.    One interesting item to note is that going by the 5 quart jugs I was using before from Mobil, it was showing that I was putting in 8 US quarts to bring it to full if not slightly over the full mark according to their jug markings. Granted I did allow more drain time this time and in part because the engine oil was only lukewarm as I started it and let it idle and not for long enough to get the oil itself hot ( the engine was up to operating temp ). The oil in that state just seemed to take forever for it to drip out but not only at the drain plug but at the oil filter housing as well, perhaps I had never quite gotten all the oil out before and I could have still waited longer but as it was I waited well over 3 hours. I think next time if I have the time I will do an experiment by dropping the oil and lets say leave the pan under it for 15 minutes, then switch to another pail and let it drip out overnight and measure how much more oil comes out. So this time and yes I ended up getting it just over the full mark as I was experimenting with trying to get the level to the add mark after I had run it and then waited some and then added a bit and waited for a certain amount of time for it to settle to the add mark. I very well may not have waited long enough for that experiment but I got to the add mark, then dumped in a full quart and waited some and checked and then waited some more and it crept up more ... and then finally oops, it was slightly over full some hours later when it really had settled all it would. I find this engine sure takes time for the last bit of oil that gets poured in to finally make its way into the crank case. I can only guess at how much too much I added as per maybe a 1/10th of a quart. I had poured in 8.5 quarts going by the quart containers as per 8 quarts and 16 us ounces. I was shocked at how much this was off compared to the prior oil changes and if those larger jugs and they are not marked accurately enough or they contain slightly more than what they say, or the drain time factor made that much of a difference. But I know on this forum there have been others who have said they have put well over 8 quarts in their L8T and now I have also going by the Amsoil true quart containers. Its a confusing convoluted mess up here in Canada with some oil manufactures packaging is in true US quarts, some is also in true US quarts containers on an even number of quarts but also marked in liters which becomes the odd ball volume of a fractional amount of liters. Then there is the Liters only containers, no US markings as its a true metric container and only measured in Liters to an even number of Liters. But remember we used to have Imperial Gallons and Imperial quarts as well !.

      Holy smokes. Clearly not a deal on that truck. I just mean in general, matte or painted trim is becoming more normative than chrome, but I know the Black Optics packages on various vehicles are being sold as uplevel trims. They look really good, but sheesh. It's just paint and plastic.

      I Wouldn't Know Where to Begin    Oh I know where I would begin but I'm just one of over eight billion people on this rock. Eight billion versions of where the goal post is. How large it should be. How far to kick from. What ball is the right ball. Elevation. Age.....are you getting the point? It isn't about disagreeing with one individual. It's about agreeing only with one individual. One's self.   Agreement comes when multiple people hold the same point already. THAT is the goal of an education. Building the Social Contract. That thing that allows us to all read this sentence. We've agreed on the alphabet and how to arrange those letters into words we agree upon whose meanings hold true for everyone entering into that contract. Those words arranged into a sentence form an idea and several sentences strung together in a paragraph convey an argument for or against or inform the reader of a state, condition or perhaps reveal a things nature. Paint a word picture. Make oneself known.    This contract is not limited to words although they are often explained by words. Things like numbers and their usefulness. Physics, Chemistry, Medicine, Music, Art and so on.    The frequency of middle C (C4) is 261.63 Hz is a first principle. We build on that to make music we all can enjoy even if we all can not compose or play. You don't have to master it to make it enjoyable and useful.    So why is the Beginning so difficult? Why is agreement so elusive?   Everyone "Signs" the contract (when receiving that education in obtaining it)  but fewer and fewer in this world have any intention of living by that contract. They find exploiting that contract more advantageous. Disruption. With intent. Without intent. In Ignorance. In your face. With a double dog dare you. With a hold my beer. In resistance to that contract and in spite how it looks on us. It permeates the very air we breath.    In this way the contract is subject to advantage. Abide by it when it serves you, disregard it when it doesn't. Unpredictable and self-serving. Corrosive.....Toxic........   It says a lot about a persons character to disregard the contract, the truth, first principles. None of it good.        ********************************************************   https://medicine.yale.edu/news-article/character-vs-personality-who-we-are-and-who-we-aspire-to-be/   Just an interesting article.

      It costs $5,250 for the Yukon Nightfall option (black wheels, emblems and illuminated black GMC grill badge). What a "deal".

      I keep getting the above error message on my 25 Sierra.  If I reset the infotainment unit (via the phone hang up button) it will work again for a day or 2.   But I dont want to do have to reset  all the time. Works fine in my 2023 Corvette. On both vehicles I connect wirelessly.   I have a Google Pixel 10 Pro XL, phone is up to date.  Any Ideas.  See attached
