But in case anyone’s reads this thread looking for an answer, here are a few issues I found on the forum that cause a noise in the rear
1.) the headrests, pull them out and spread the prongs out just a little to snug up the fit
 
2.) Make sure your tire jack is secure 
 
3.) The seat belt covers in the c pillars are loose and can rattle
 
4.) And if your hearing a pop once in a while,  it’s your spoiler on the outside of your car
 
5.) lastly, check the chain linkage for the rear slider power wire. It presses up against the glass
 
 
 
 
Did you put something between it and the glass to help the noise?

I’m debating what to do, I have some 3m Tessa  tape I use for car audio installs that I think would work good. I’ll have to spend some time taking a better look to make sure whatever I do, do to it, d

Tighten the jack under the seat.

That would be the best idea (after taking it to the dealer) rather than having people on the internet all across the country with no access to your truck trying to diagnose it...

Dealers are terrible at fixing squeaks and rattles.  I can not count how many times that  I have been told that they can not replicate the problem, not just on GM but all vehicles.  I have the same issue on my 2019 rear seat left side.  I will find it and fix it myself as so as I can.

I'd be interested in what you do to fix it if you don't mind posting. Thanks!!

I cannot comment on the specifics if it would work but it looks like some tessa tape or even really thin window sealing would work. Just apply it to the glass and not the chain linkage for the wire harness and you should be fine. Double check that where that rests on the window does not get in the way of the travel on your window so you don't possibly rip the tape off and get it gummed up or jammed in the track.

If the dealer can not replicate the problem then offer to demonstrate.  If you and the dealer are unable to make it "act up" then at least it will be on record.  In the past I've had service advisors report that they were unable to replicate a problem but I can't ever recall being ignored on the second visit for the same issue!

If I had a second car And I wasn’t handy at removing car panels and etc from doing stereos I’d probably would take it to the dealership , but since I didn’t buy the vehicle from my local dealer, there about 50/50 on giving me a loaner sometimes. And I just can not run the risk of not getting my truck Back in time. I’m also scared of them touching anything on the inside lol. Maintenance I’m cool with, but I’ve heard horror stories off them just destroying panels either with scratches or leaving grease stains

While I was fixing the rear window rattle, I also noticed the metal tabs for the child restraints will rattle if there not pushed completely solid to the back. I shoved some foam on the front side of them to put pressure on them just now

Mine 19 had that rattle and so does my new 2020. Drove down 10 miles of washboard dirt roads this weekend, man did that rattle get annoying. OP did you figure out a way to stop the rattle and confirm it was gone?

So glad I found this thread, this has been driving me crazy.

To summarize, it's not the jack and not the passenger seatbelt (in my case anyway). I also have a power sliding rear window so I suspect that's it.

 

Please post any solutions you come up with. I'm going to tackle this on the weekend if no one comes up with something. Not sure what yet :)

I did find folding down the rear headrests got rid of some of the noise but not the main rattle from the window

Remove the rear headrest and flip the seat in the up position. This fixed the noise for me, well, temporarily until i figure out the root cause. If you slap the back rest portion of the seat with some force ( seat down) i was able to duplicate the noise. I think it might be the vents that let air escape when the doors shut or the headrest, ill look at the chain to since that was mentioned earlier.

Did you resolve the rattle? I ha e the same issue, only rattles when seats are down, if someone is sitting in the back seat or raising the seat it doesn’t rattle.  Dealer says it normal but I have a hard time believing that.

I'm inclined to think it's the cable housing rattling on the back window (like in the picture above). I think everything else that people are doing, like folding seats, having a passenger back there, or folding the headrests, is just changing the weight on the backrest and causing it not to rattle.

My plan is to wedge something small between the cable and the window. If that works I'll stick some velcro on the window (only the window, soft side) and hopefully that cures it.

If not, I'll really be stumped. I'll report back with results.

I also have a noise like that in my  2019 High Country with 125 miles....

I wanted to stop and tear the truck apart! Thanks for the info. I will try the same thing.

Had a similar rattle, had kids in back seat one day. They both said it was there head rests. Took to dealer, getting recall stuff done too, they fixed the rattle said it was the seat back latches.

      This is interesting. My quote tagged here is different from my original quote. After I’m driving them longer. That isn’t me. I don’t talk that way. I definitely wouldn’t express myself that way. Interesting.

      What have you done to your K2 today?

      By UrbanRage · Posted

      I have the same running boards on my truck and I do agree they are bulky. I also find myself stepping over them when getting in and out of the truck. Besides providing protection to the rocker panels, they aren't very useful.  I will be replacing them soon with the Amp Powersteps.

      OCI, not when but why?

      By Grumpy Bear · Posted

      10 Ford and Chevy engines proven to reach 300,000 miles   You may note a common 3K OCI on this list of gas motors. I skipped over the diesels. Dh'O.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By jake111 · Posted

      Thanks newdude!  By the time manual selection is needed, I'm probably too much of a control-freak to depend on the transmission sensing braking to activate automatic downshifting.  I would be anticipating the situation and already be manually downshifting.   This truck replaced a 2004.5 LLY diesel with the Allison 5-speed.  Putting it in T/H made noticeable differences (when the torque converter locked, upshift points, downshift behavior).  On this 2024 gasser with the 10L1000 I haven't been able to detect much, if any, difference.  Ok, I can never tell now when the torque converter locks up.  But I also don't notice differences in shifting.  For downhills, I've probably already manually downshifted by then anyway.  Since it's also more awkward (than the 2004.5) to engage/disengage I don't even bother.  Or maybe it doesn't really matter with just a 3k lb. camper in the bed?   Thanks also for the list of reasons the charging system might select various voltages.  However, what I am seeing doesn't fall into any of those categories.  It very definitely, and very consistently, rises after coasting/braking.  Maybe not immediately, but not very long after coasting/braking.  Very consistently drops voltage when no longer coasting/braking.  It might also be interacting with the camper battery charging (I might disconnect the camper and see if it changes the charging behavior).  I also need to recheck turning on headlights for when I want to force it to charge the camper.   Another JR, in June I converted the camper to LiFePO4.  Since it's not a good idea to try to charge lithiums directly using truck, I installed a Victron Orion XS DC-DC charger (which BTW is AMAZING!!).  Being cheap, I only had to buy that one item (besides the battery, of course) to do the conversion.  The camper OEM 120v battery charger (only 19 years old and works perfectly) and the truck feed the input to the DC-DC charger (not at the same time).  But I didn't want the camper charger feeding back to the truck so I kept the old separator.  I considered replacing the separator with a 30amp diode but that means more work and might add another 1/2 volt drop.  One thing that surprised me was the voltage drop over the long 10awg wire run, so I can only charge smoothly at 8 amps (because the DC-DC charger is completely configurable).  Another reason I don't want an added voltage drop with the diode.  I might also be a little lazy but all this work is being done under the sink with a small cabinet opening.
