Knock on wood I have also not had this issue on my 22 lt w/ multi-flex.  My truck lives outside in snow, rain, and gets washed frequently.  Hoping this never does happen and would like to kno what the definitive reason is behind it and the fix to go along with it

I have had my cover off and can confirm the switch is underneath the holes, another reason to plug the holes is the switch and linkage will freeze in the winter after getting soaked.

Did anyone ever have a problem with a good old fashioned manual pull tailgate? Yeah me either. Sometimes reinventing the wheel is unnecessary. I wish my truck had a manual old handle.

I disagree, I love the tailgate. I've always driven a Ford F150 and decided to try an AT4. One of the things I like the best is the tailgate. If I'm hauling dogfood or anything in the bed it makes it

Well, chalk up another inner tailgate switch. I started to head out this morning and my dash said “Inner Tailgate Open.” So I checked and it wasn’t open nor was it even unlatched. I tried to open it but the switch was not working. The main tailgate switch worked fine. Whenever I tried the inner tailgate the taillights would blink three times. I started the truck up and the flashers would blink three times, stop, and then blink again. I opened and closed the main tailgate several times to see if that would clear it but it didn’t help. The lights quit flashing eventually and they also quit flashing when I pressed the inner tailgate switch. But the switch never worked again, not that I expected it to after that. Truthfully I have lost count now as to how many switches have been replaced. I do know that most of them have been the inner tailgate switch. 
Late yesterday, I had the truck bed loaded with firewood so when I was done unloading I hosed the bed out. I’m even more certain than before that water intrusion is the culprit. Why water doesn’t have that same effect on everyone’s truck I have no idea. Back to the GMC dealer on Monday. This is getting real old!

You have to have another wiring issue. There is no way you have that bad of luck with those switches. We've had the wettest year in a long time here, along with me going through high pressure car washes on a regular bases, and I've had zero issues. I'm absolutely sure our tailgates & switch configurations are identical. I'd definitely be looking elsewhere for the problem & solution. If you hold the inner tailgate switch down for 3 seconds, it'll lock it so it won't open it, making your lights flash. That is for when you have a stinger in your receiver hitch. GM put the sticker on the drivers side inside the jamb of the tailgate that shows how the lock works. It sounds like you just have yours locked, try holding it in for 3 seconds & it'll unlock it.

Yes, I’m aware of the lockout feature for the inner tailgate. Actually I thought that it was 5 seconds but either way it’s not that. I’ve used that before when I had a bumper pull trailer last year but I switched to a fifth wheel this year so I haven’t had to lock out that feature. It could be another wiring issue however when at the dealer they replace the switch and it will then work for a while anyway. If it’s a wiring issue shorting out the switch wouldn’t it blow a fuse first? It doesn’t seem coincidental that after I hosed out the bed of the truck and the tailgate that I had the switch go bad the very next morning. I have an appointment tomorrow so I’ll ask the technician if he thinks that the problem could be up the line and not the switch itself. The entire problem doesn’t make sense however there is a TSB on the switches getting wet.

On the way to the dealership this morning I was sitting parked inside the truck and the flashers would blink 3 times real fast and stop. 10 seconds later it would do it again. This simulates the 3 fast blinks on the taillights that happens when the inner tailgate lockout is activated. 
When I got to the dealer the inner tailgate switch was working! 
The dealer checked the Body Control Module and evidently it threw a code. They reprogrammed the BCM. So far so good.

Wow, some crazy stuff going on there! Well, maybe that BCM was the issue, hopefully, huh?

The TSB speaks of replacing two parts.  The Recall speaks of replacing the touchpad...are the switches and touchpad one in the same (one part)?

 

Also, how is there a stop sale on all of the new trucks when they had the new parts since July 2023 (TSB)?

 

TSB 23-NA-112

 

Recall

 

BTW...are there two threads on this same topic or is my mind playing tricks on me again!

Well, it's very odd that a few people have had to replace several switches, when others have had zero issues. I'm still not convinced water is the culprit as my truck(s) have gotten plenty wet several times. I'm more convinced that a BCM or other electronic system glitches is the real cause, like just plain cheap Chinese parts. I've seen several cameras fail also, just because of their quality. Did "Slathering" on the silicone resolve anyone's issues???

I’m not sure what I think the cause is. My fob started acting up sporadically (and yes, I tried new batteries). Both on locking/unlocking and with the ignition. I took it in today thinking that maybe the BCM was also the cause of that (in addition to a previous BCM problem with the tailgate). Diagnosis was faulty fob and they ordered me a new one. 
I did silicone (a couple of neat inconspicuous dabs-no slathering) my tailgate grab handle drain holes long ago. It didn’t help. I’ve posted that I lost track of how many switches I have had replaced, mostly inner tailgate. The recall does not have a remedy as of 2/9/24 but I read that there is a stop order on all new sales so I suspect that a fix shouldn’t be too far off since GM no doubt doesn’t like to see zero sales of a high profit vehicle.

      OCI, not when but why?

      By Chuck FB · Posted

      I had skimmed through that article when you posted the link and honestly I felt rather defeated in a sense and realized that all these years in changing oil that in fact putting in what I was told was a good quality oil was probably not filtered as well as it should be although the filter put on the engine would be what ( as long as it never went into bypass mode ) would be the final filtering of the new oil that the engine components would first see, but then the filtering media itself is not up to par to what is ideal because a full flow filter would be too restrictive to filter fine enough for the engines best outcome in the long run. Only one of our tractors over the years which was a Versatile with a 855 Cummins had a separate bypass filter, some engine manufacturers did spec a partial bypass system within the main oil filter but I don't believe any other trucks or equipment I was servicing used such a filter. No doubt a product like the Amsoil bypass system is of benefit as long as nothing goes sideways with the extra plumbing and filter such as a rupture/leak that could cause the oil to pump out of the engine ( yes that Versatile had a remote canister with hoses routed to it as well ). With the idiot egr system on a diesel and as a result forcing a lot more soot into the oil, that certainly isn't helping the diesel engines cause or as you pointed out the GDI engine issue with creating more soot and aside from having a fancy secondary filtering system, changing the oil more often helping lower the total soot load.     So oil manufacturing and the end product is not something one can control and I wonder if there are specs on what various oil packaging companies produce in particle count or size. As to the filtering, if the OEM is not designing a filter size and spec that is really what it could be, they too are short changing the end user and so what is the answer. Of course as you say the oil side can only do so much if the air side isn't keeping up its end of the picture and air filters are only so efficient and if in a dusty environment such as farm or construction or driving gravel roads there is a lot of dirt to filter out and some of that ends up into the air stream.    Of course the irony in places like where I am where they dump the salt on the highways but also will mix in some calcium or outright pure calcium for problem road area's, or using calcium as dust control on gravel roads, the vehicle that gets used in that environment may rust out before a properly engineered engine and maintenance finally wears out so one has to face that reality in the rust belt.

      Oil Change

      By Erfar · Posted

      have you stuck with dealer oil changes since then? I made the same switch after getting tired of crawling around under the truck, but I’ve found some dealers are way better than others about getting you in quickly. Curious if yours has been good about scheduling or if you’ve had to look elsewhere for quicker turnaround.

      Can anyone decode a VIN to determine if this truck has had emissions issues or a recall?

      By cherryred21duramax · Posted

      Thank you.   I am set on a 3.0 Duramax as my previous truck with a Ford Ecoboost had just as many, if not more, "common" issues.  Cam phasers, timing chain issues, 10-speed valve body and CDF drum, emissions issues, etc.  So I figured, why not get 2x the fuel mileage (these things got 27+mpg on every mixed city/highway test drive I put them through) and better towing capability with resale value to boot?   My minimum, shortest trip will be 50 miles 1-way and I regularly go out of state with a travel trailer.  I'm planning on using this for a marketing/event promotion business also, which would require regular towing of trailers for bands, DJs, sound and lighting gear, along with my personal camera gear for filming events.   Looked at other trucks in the $30k+ price range but the issues seem to be everywhere, plus too many with gaudy mods.  I'm literally sticking with RWD trucks because they tend to be actually used as trucks, vs. the 4x4 models I've seen with unsafe lifts, huge tires, and general mods that would affect reliability (I'm wondering if some of them were tuned, hence the aggressive throttle response and hard shifting).   So my goal is to find a stock, 3.0 with 1 or 2 owners, in good physical condition, and decently well maintained.  Can't seem to find that up here, everything in the $27-30k range has had multiple owners, smoke smell, issues, or body damage.  Or the ridiculously modified trucks with 80k miles for under $27k but lots of problems...

      That’s pretty tough Grumpy. I reread the previous few posts. They all reference oil changes. Much like your last thread. In my humble opinion it keeps things interesting.
