That annoying horn chirp.

[WalleyeMikeIII]

I am enjoying this thread because my 2022 Yukon Denali also seems to give me random chirps. Not all that often but it did happen two days ago for no reason that I could figure out. I have pretty much learned to think about it, but also to ignore it. As I have said before, I think the new vehicles are using some version of the HAL 9000 software.

Totally agree...it does seme to be a little off..

Starting to think @tgilwright's issue is that the car is confused and is "off cycle," like it thinks he is in the vehicle when he isn't and thinks he is out of the vehicle when he is in it...Maybe disconnect the negative battery terminal for a half hour and start over.

What are you doing, Dave?

Bought gas this afternoon and you'll never guess what it did after I got back in the car and closed the door. I'm going in for a couple of minor warranty fixes in the next week or so and while I'm there I'm going to suggest they first experience this disorder, then fix it. I do believe they can reflash the ECM, if that's what it's called, and assure that the software is fresh and correct. Haven't had this much fun since my root canal.

Maybe there's a third remote squirreled away somewhere?

Well, that's at least a REMOTE possibility.

 

[tgilwright]

Seriously, if there was another remote shouldn't it chirp EVERY time I close the door? There is no explanation that would account for how this thing behaves. I was hoping that someone else also has this problem and has fixed it.

I have searched all over and it seems that I may be the only one with this particular issue. 2021 Tahoe. Usually, when I enter the vehicle in the garage after it has been unused for at least one night, when I am sitting in the driver's seat and I close the driver door , the horn gives me three quick chirps. This is before I even think about starting the vehicle. Occasionally it will do this away from the garage and after only sitting long enough to gas up. The key fob, of course, is in my pocket. I have been through the vehicle setup menus more times than I can remember and my service manager at the dealer is at a loss. Is anyone else having this problem?

My 2022 Premier does this also...Gets on my dang nerves..I have all the tag turned off and still does it..

I believe it. I had mine into the dealer today for an oil change and a couple of other small warranty items. The dang car decided not to act up today. If it doesn't show the symptoms the techs can't fix it. My wife's 2022 Buick Enclave is now doing this too, at random times and random locations. All alarms are turned off in the setup menus.

Silly question, but when you leave the vehicle, are your keys always going with you? Do they get stored near the vehicles when you are at home?

 

[tgilwright]

The fob is always in my pocket. In fact every time I go to the garage, such as to take out the trash, the car spools up, projecting the logo on the garage floor in the rear and, I assume, pressurizing the fuel system.

My 2022 Denali just gave me the 3 chirps when I got into it after filling the tank at the gas station. Did the same thing two days ago. I turn it off, get out and fill the tank, then when I get in before I even start it I get the 3 chirps. I figure it is trying to tell me something, just not sure what that is.

 

[WalleyeMikeIII]

Mine has done it at the car wash a couple times...but, I think that has to do with the fact that they open the driver door to let me out, I get out w/ the fob in my pocket, and they never actually close the driver door. They finish drying it, and signal me to come back and get in. I do, and shut the driver door...so in this case maybe the vehicle thinks I left the fob in the car.

Chevrolet Silverado Beeping? (7 Common Causes) - Engine Patrol

The Silverado is Chevy’s best-selling vehicle. Like any other vehicle, it uses beeps, chimes and noises to alert the driver’s attention. If you’re unsure why your Silverado keeps beeping, this guide is here to help. Chevy Silverado 3 Beeps The most common cause of unknown beeps coming from a...

Found that article, has a point you might want to check:
Replace Fob Battery
Or, maybe one of the door sensors isn't actually working...

If you can dial in the sequence that causes it most frequently, a trip to the dealer to show them may be helpful.

Here is another thread over on gm-trucks forum seemingly complaining about the same thing:

Horn honks 3 times after I enter truck and shut door.

For the past few weeks my truck honks every time I close the door in the morning. I’ve had that feature disabled for months in the settings. This is annoying because I leave before 5am and I’ve got a sleeping household to not wake up. Anybody else having this issue? Know how to fix it?

www.gm-trucks.com

The one that is most annoying to me is the "Fob left the vehicle" when running alert...since I often leave my truck running when hooking up my boat, or launching or retrieving it at the ramp.

 

[Chad G 1979]

did you close the door while filling up? i fueled up earlier today and fob in pocket and closed door and it never chirped.

 

[tgilwright]

Once again, this problem is intermittent and unpredictable. According to the manual the three chirps occur if 1) the car is running and the fob is moved outside the car and the doors are closed, 2) the fob is left inside the car when not running and the doors are closed, 3) the car is tampered with while the alarm is active and the driver pushes a button on the fob (which button I can't recall) to determine if there has been activity while alarmed. We're not talking about chimes, but rather horn chirps. In my case, the fob is always in my pocket and the car is not running when the chirping occurs. It is either when I get into the car and close the door or when I get out of the car and close the door. Pretty simple. The dealer tells me it works as designed because it won't act up when it's in the shop. I understand perfectly that if it doesn't present symptoms the techs can troubleshoot it. It will be chirpless for three days and then start chirping every other time I get in or out for the next two days. The really fun thing is that my dealer's service manager is starting to experience the same thing with his '22 Silverado. And my wife's '22 Buick Enclave is starting to act the same way, occasionally. It seems to me that if it was acting normally it would be consistent, not intermittent. I think I'll replace the battery in the fob tomorrow and try it for a week to see if that makes any difference, but it checks out as healthy on a voltmeter.

 

[WalleyeMikeIII]

One other thought. Try unhooking the neg battery cable for 5 min and reconnecting. Maybe it needs the ole <CNTL><ALT><DEL>.

I do think there must be some software related isssue here…Totally understand it’s not chimes.

Perhaps ask the dealer for the latest BCM calibration to be installed and update the infotainment unit? Mine has chirped a coulple times when I didn’t think it made sense…but yours seems a bit more intermittently often.

Good luck man! Not trying to be annoying…just tryin to narrow down what causes it.

I'm pretty sure that one fix would be to introduce 12,000 volts to the auxilliary outlet in the console, but I don't think the warranty would cover the ensuing fire. Then again.........

Would probably just blow the fuse and you’d be right back at the annoying Chirp

We've already seen the aftermarket fix for the start/stop function. I hope someone comes up with an incredibly profitable reprogramming fix for these vehicles that allows us to kill some of these alerts/alarms as well as allowing us to select music from our USB drives while driving alone. I know I'd pay up for such a mod. I love the ride and most other attributes of this vehicle, but I'm starting to seriously miss my 2011 Suburban. If the lifter issue ever raises it's ugly head here I'll be a basket case. Never should have quit drinking!

I think the key is to embrace the quirks.

98% of the time, I am thrilled w/ my Denali. 2% of the time it does some odd things, but most of them are quirks vs. affecting major function. Agree, the horn chirping is annoying...there are some annoying software issues, I keep watching and looking for updates (NHTSA web site is a good place to do this), and asking that they get applied when I go for service.

But, there are definitely times where the infotainment system bugs out...doesn't show a screen, has low performance, doesn't connect to my phone, etc. It is guaranteed its a software issue.

I was thinking, during this crazy supply shortage, the GM had to be trying to find ways to keep the builds going, and this could include qualifying 2nd or 3rd suppliers for some of these modules. Possibly they are slightly different, and cause some software anomalies...consider the DRL/Headlight issue and sensor...turns out that was a software fix, but probably tied to 2 different sensor suppliers...

I was watching a you tube the other day from a Marine mechanic, where he listed the 10 worst outboards, and #4 on his list was "CoVID motors -- thats right, any motor built during the pandemic." Makes a guy think.

Net, just try to enjoy your ride for what it is...a pretty dang sweet vehicle, with a few quirks to give it personality...its like the pretty girl w/ a beauty mark or two.

I have a 2019 so our infotainment systems are nothing alike - however I do have the "remote left in vehicle" horn chirp disabled as well as the "check rear seat" alert which is there to remind you if you've opened the rear door before opening the driver door and haven't opened the rear door when leaving your vehicle, for the absent minded parents who leave their kids in the car. Every once in a super rare blue moon when I get in the vehicle and shut the door I too will hear that "remote left in vehicle" horn chirp. I have no clue why, I just assume it's a bug!
