Tailgate opening no notification

Just brought home my 2023 Denali and I already have a tonneau cover on it.  I stopped for fuel in the rain and then drove probably 6+ miles to my destination.  I'm unsure of if somehow I hit the button twice in my pocket or what, but it seems strange to have happened.  When I got to our destination, I went to back into the parking spot and noticed that the camera was looking at the license plate instead of behind me. I'm worried about this becoming a problem because I usually carry my tool bags and such in the bed of the truck and would hate to have the gate open and I would have no idea since I can't see it in the rear view or mirrors.  Anyone know why it would have opened or if GM can notify us on the newer vehicles?  My 19 Silverado would let me know if the tailgate was done with a simple notification that I could dismiss.  This is so far the only true issue with the truck.  I've seen that there have been others with the issue of the multi pro tailgate opening on its own and I do pull at trailer on occasion and if that were to happen it would definitely F up the tailgate.

My 2021 pro tailgate erratically opens and sometimes switch doesnt work when pushed. I've noticed it seems to happen after a rain or washing. The top switch gets wet and shorts out. See Technical Bulletin # 23-NA-112. Needs the switch replaced.

I'm a little confused on 1 point.  How could you not know if the tailgate is closed when looking in the rear view mirror?  Is the "spoiler" looking ridge not visible in the mirror?  I have a 2020 and have had 2 tonneau covers on my truck.  One was the Rough Country trifold.  The one I have now is a Retrax.  With both tonneau covers closed, I was always able to tell if the tailgate was up.  Was there a redesign of the top plastic trim piece I missed?

 

As for concern about the tailgate dropping while pulling a trailer, have you looked into the GM accessory that should prevent that from happening.  Iirc, it's made by Curt, but don't quote me on that.

My 2021 Silverado started having this tailgate issue over this past weekend.  I have an appointment in 2 weeks, assuming the fix will TSB 23-NA-112.  I'll reply after the issue has been corrected.

Is there any mention of a battery drain on any trucks? I'm having the same issue with my keys as well. Now, there is a parasitic draw that is draining the battery.  I go to pull the fuse for the theft system, there isn't one. It's supposed to be on the driver's side, on the side of the dash.  I have an appointment at our GMC dealer for May 2nd.

Thank you.

My rear view mirror  is a camera and no I can't see it. Hence my issue.

Flip the bottom lever over to regular mirror, then you can see it.

Tailgate issue was fixed yesterday, TSB 23-NA-112 was the fix.

I had the exact same issue.  Decided the first time it "could" have been one of us bumping the switch when we stopped in parking lot, as when we got out it was down. We knew it was up when we left home because I could see out the cameras. The next time this happened, unfortunately, told a different story. We were pulling our camper to an event in September. As I was driving in the area to park the camper, making the last turn of 3 (without stopping), I heard a CRUNCH!!  Yep, it came down on the last turn and hit the jack on camper. Not a pretty site. I have attempted to email & contact GM since it happened. I haven't gotten 1 single response. 

 

Last week I FINALLY found out that the first week in November a bulletin was posted by GM stating an issue with switch that they are replacing. Have one on order at dealer now.  Now I wait as the dealership is going to fight for my damage to be fixed as well. Such a disappointment as I'm on my 3rd new GMC Truck and can't get any sort of a response on this. Customer Service should be a priority, but sure doesn't seem to be with this from all I've read on the same issue.  Hope you got yours fixed!!

Will check out this TSB as I have a 2024 1500 Sierra and have noticed my tailgate being down without using buttons a few times in the last 3 months from delivery. One time was about 20 minutes after washing truck. Thanks for TSB number.

Did you have to prove to dealer to get fixed or will they address simply because you bring it up?

Pretty sure there's a recall now. Call your dealer and they can tell you if your truck is in it.

This has happened to me 3 times.....although like you, the first time I went in to get groceries, and when I can back my tailgate was down......thinking the key fob button was pushed accidentally in my pocket......fortunately nothing was in the back.  Second time, a bit more serious.......I was driving for over 100 miles on my trip, when I came to a near stop in heavy traffic on the expressway.....then when we resumed, another car flagged be down, and sure enough, my tailgate was down......and garbage was spread over the last mile......fortunately nothing of value and did not damage vehicles behind me.   I was not so lucky with my truck......I had ice build up on the bumper, so when it went down, it dented by tailgate which will have to be addressed when the problem is resolved.    Third time, after having it looked at by a local dealer, I left to go home, stopped for gas including 3- 5 gallon cans in the back......went a few miles, having the tailgate open.....and going around a roundabout intersections the 3 full cans of gas were spread out across the road.....fortunately no gas escaped and no one was injured.  A concerned citizen tracked me down, and let me know the situation.  I am so glad it wasn't my hunting rifles scattered down the road, and certainly am glad this hasn't caused any injuries or damage that I know about.

 

I don't understand why there is not any indication of the gate being closed......green light or red light (the gate is open)on the button....there seems to be a spot for it.  Although there is a known issue, a gate ajar warning of some time is needed, this is a major liability for GM and for the owners of these vehicles.....I own a 2023 Sierra 1500 AT4.

I meant to say the tailgate opened unexpectedly and the gas cans went flying out the back on my way home, just so we are clear.  

 

The other recommendation I would have, is move the button away from the emergency flasher button.......when you are rapidly trying to push this button is a hurry given the situation, it is too easy to hit the tailgate button.

      OCI, not when but why?

      By Grumpy Bear · Posted

      Sad thing is that this doesn't have to be the case. LSPI can be solved without a reduction in TBN. Swap Ca for Mg.  Cats are not a issue if the OEM can get a ring and valve guide seal even at SN levels of SAPS. Dizzy is purring like a kitten with a bowl of warm milk. 200K of Full SAPS oil and zero detonation issues and nice a clean inside and out. This shouldn't be an issue. It isn't 1920.    Tell ya what AMSOIL SS is excellent at, internal cleanliness. The new formula is even a step up from their already outstanding cleanliness levels. Can't say the OEM offering is quite that clean. There marketing suggest the SS is cleaner.     That is the only defense with at shelf oil. Nothing wrong with them if you ignore the marketing and OEM 'recommended' OCI and use a thimble full of common sense. 😉 You go sir.

      Roll up bed cover experiences

      By StingerZ16 · Posted

      I started with a folding cover by BAK PAC on my 2500. It went bad after close to 5 years. Bent and vinyl coming loose. Contacted BAK and they gave me a very good discount on a Revolver. Had it a number of years. Mostly outdoor storage. Some garage storage. Vinyl started to come loose. Still under warranty so they replaced to cover. Sold the 2500, bought the 1500 and got another revolver for it. Had it a couple years now and no issues. I store it indoors. Got a bit of discount when buying it as well. If you are seeing problems, contact BAK or real truck and let them know. Customer service was pretty good. But I think they changed their warranty.

      Towing In Loose Gravel

      By Chuck FB · Posted

      I agree, there is no one answer fits all as every rig is different, one may be pulling some little aluminum fishing boat while another is towing a monstrosity that weighs a lot and hopefully the owner if the rig has some prior experience to know what drive mode they should choose.    It also struck me and this is from watching a few of those boat ramp escapades videos in the past, Ford being one of the vehicles that has the auto front axle hubs and sure enough its found out that one hub has crapped out and won't engage and may not have manual hubs to even select on both sides so they are on the boat ramp stuck with no four wheel drive and spinning .... they flat out need a tow to get up the ramp and deal with the vehicles new found issues. That can happen to all brands of pickup, finding out either four wheel drive or 4 low isn't working right at the time its needed it to work as some electronic crap has failed.

      Towing In Loose Gravel

      By Chuck FB · Posted

      Its possible you never had the joy of the crappy boat launches we tend to have around here or really some of them are just grades down to the river if its a river scenario and the conditions change all the time with the river levels and silt deposits. Some of the lakes we went to years ago, there was no such thing as a cement pad that went down into the water that the trailer stayed on, it was gravel maybe up to the water line and then duck crap much beyond that so sinking the boat tires into mud. Of course some of the more established lakes had a cement bar type boat ramp but sometimes it was covered in green slime closer and certainly within the water and a two wheel drive had all sorts of fun if one had to touch that slime with the rear tires.    A neighbor of mine had made a comment years back with his chev truck that was probably about the same year as yours but a half ton extended cab 4x4 and he a a fiberglass boat with an inboard so it wasn't a feather weight and he had gone out to one of the large popular lakes in the area and don't ask me how this happened but he was in two wheel drive as he figured he didn't require four wheel drive for that boat ramp and somehow upon pulling the boat out he twisted one of his drive axles. I suspect it must have spun and then grabbed on the cement ramp and shocked it to the degree of twisting it. He would have had the standard 8.5 or whatever it was axle housing as the 9.5 ring gear like my truck has also has larger drive axles as far as I know. Anyway he was feeling a vibration driving home and had it checked out and a shop found that the tire/hub was wobbling because of the axle had twisted so in went a new drive axle. After that bad experience he said he made sure to put it into four wheel drive to lower the stress on the rear axle. Of course that is where an HD truck can handle a lot more stress and no doubt these newer half tons with their larger ring gears probably have larger drive axles as well to match vs back in the day.

      2027 GMC Sierra: Official Discussion

      Desirable - as in does someone WANT one, aspire to have one. Could reasonably buy any car they want and CHOOSE these instead.    I didn't watch the video, why did they win?
