I have a 2024 2500 diesel at4x AEV edition and a week into ownership the tailgate started to open while parked. After it opened it would continue to unlock every 30 seconds, eventually killing the battery overnight. Brought it in to the dealer and they said there was a service bulletin and replaced the switch. Now the tailgate is fixed but the headlights flash for no reason. Also causes the wiper blades to stutter when the headlights flash. See attached video. Bringing it back to the dealership for some more head scratching. Anyone else having this issue?? Or any ideas?

No similar issue with mine now six weeks old and 1300 miles, except an emissions alert however interested in the service bulletin; do you have the bulletin number from their job sheet please? I just had wheel alignment and ECU/TCM flashed/updated yesterday for emission update. How does it drive empty?

I replaced mine with smoked and they look great especially on my black onyx vehicle.

Brought the truck to the dealership today and they replaced the fender marker. The headlights flashing were related to the light module? Maybe when the tailgate switch malfunctioned and killed the batteries it glitched the light module As I understand it from the service tech. They disconnected the module from power and the blinking was corrected. Ordering a new module to be sure. They want the vehicle to be perfect. Excellent service.
 

That tailgate switch will continue to fail, unless you seal the 2 holes up. Stupid engineers.

That is useful to know. I've had my 2024 2500 diesel at4x AEV edition for a few weeks now and no such issues. What is the answer? Plug the holes before an issue occurs? If plugged, water would accumulate in that pocket. Or get to the area behind the switches and spray them with an insulating spray. Need to think about it.
 

Most just take black rtv silicone and dab the holes close.

Yes, the finger hold indentation will fill with water, but oh well. Better to spell a little water on your boots, than to have it constantly get the switches wet. We have not come up with a good reason the engineneers put it on the HD's, but not the 1500's.

I will look into it today.
 

I don't think its hard to remove kicker sound system from the tailgate and spray switches with a water protecting sealant (assuming the switches are bare). As a quick protective fix I put in long silicon tubing, about 8" (I use for my RC Planes fuel lines) in the holes and put some sealant around them. The holes will still drain but to an area below/away from switches. The silicon will take a little time to dry. Not a perfect solution but will do for now.

Haha solid!
 

Same truck back in the shop for an apparent diesel exhaust fluid heater. Tank needs to be replaced. It's been at the shop for 3 weeks as no parts are available. What a joke.

I was under the impression gm took care of that problem! Just to be clear, your truck is a '24?

I have been running my 21, 22, and 23 just high enough to keep the dic warning off, of low def fluid warning, durning winter. My thought process was less ice cube to melt, allowing the heater not to run so long.

I was now going to keep the tanks full and make the heater wiring connection fail under warranty once the def tank supply was no longer on national back order! But now I don't know what to think.

Wow! How did you find out? Did CEL come one?
