Unless your North of the border.
My money is on the USA LD's will be included eventually. Just so many switches to go around. Spread the recall out.
My money is on that the gasser's 10speed will be on the valve body recall, also.
Your money would be in the right place, if it's betting on this issue affecting USA 1500's as well. I have a 2021 AT4 with 30K miles on it, assembled in Fort Wayne, IN, USA. This past week, upon going through the wash, my multi-pro tailgate automatically opened while standing 20 feet away (was not touching the fob, nor pressing the button). Upon closing the tailgate, it re-opened and repeated another 10-15 times, then finally stopped, until the next day. This went on for a few days.
Upon doing the online searches and seeing the recall info (N232426400 or N232426400) for the 2500 and 3500 HD's , along with some in Canada, all describing exactly the issue I encountered, I contacted my local dealer who said there is nothing they will do for it under the recall ... as it's not in the recall. Yes, I agree with all of those who think that is ridiculous. So, I figured out there issue with mine, at least fairly quickly. If this helps you out, great! Here's what I did (Note: I am not a mechanic, nor know the 'exact technical terms', I'm sure there are other ways to figure it out, there are some videos which show the how-to steps on replacing the switch, so depending upon your configuration, may be different, etc.):
1. Opened tailgate and top part of the multi-pro tailgate to fold down.
2. Opened the step of the top tailgate.
3. Removed the panel with the T15 screws where the tailgate button assembly resides.
4. With a nylon pry tool, removed the two (of four total) center black square (~6"x~6") plastic pieces to access the back of the assembly.
5. Removed the switch with the yellow wire (bottom button for the whole tailgate). Note: The switch with the blue wires on top is for button for the top of the tailgate.
6. Upon removing the switch with the yellow wires, I removed the rubber cap which was loosely attached to the switch assembly. Inside is the actual green silicon switch (which is triggered when you push the button to activate the tailgate release), this was clearly corroded on the actual switch contacts and showing corrosion residue on the rubber cap.
7. I carefully cleaned the corrosion from the contacts, cleaned the corrosion residue from the rubber cap, tested it by hand and upon re-assembling it, had no more automatic opening issues.
Putting it all together, at least in my head and performing those steps: Had there been a decent seal from the rubber cap to the switch, water would not have entered the switch, corrosion would not have occurred on the switch, the short would not have been possible, and my tailgate would have functioned as expected versus how the switch closure assembly was engineered and enabled this issue to surface. Perhaps it was developed in a dry climate.
I did order a new switch and will replace it. If it comes with the same rubber cap, I will apply a sealant to it so this does not happen again. This will cost about $10 and take me about an hour.
Hope this helps.
