My 2020 2500HD Duramax LTZ has this issue. I have not taken it to the Dealer yet. Has there been a resolution, other than hitting the latch with a BFH?

The same shuddering noise is occurring with my driver door when going over a bumpy road. Any updates on a permanent fix? Thanks

Has anyone had any luck with a fix to this issue? I’ve had my 2020 3500 LTZ to 2 different dealers a total of five times now. All say they couldn’t recreate the noise. With the help from the dealership where I bought it we figured out how to recreate the noise by rolling the window down and shacking the door vigorously. The dealer says they can’t fix and I’d need to take it to a dealer with a body shop. Took it there twice to be told that  they were normal truck noises and if I had anything in the door pockets or that my seatbelt latch could tap the side of the door and make noise. I feel as though he talked down to me because I’m a woman. The second time back he told me it was normal truck noise and that I’m not familiar with normal truck noises. When I rolled down the window and recreated the noise he told me that the door needed the support of the window being up. With it down the door would rattle. SMH 🤦‍♀️

Definitely not normal.  I had my buddy ride in my truck because he didn't believe me that there was a problem.  When it happened, he was amazed.  We have identical trucks but his isn't like this.  My only thought is something went wrong with where the door latch or hinges are located on some of the trucks.

Didn't gm come out with some kind of afterthought hard tapered plastic piece that was screwed to the bottom of the cab jamb on the old heavy duty square bodies, to keep the doors from thunking on rough roads?

 

I know it's been some odd 50 years ago, but someone has to recall this also.

Tried something a little different, had some dense foam strip and mounted it on the upper side of latch guide. This has tamed down the thumping over bumps but still have a bit of rattle depending on outside temprature.

I had my dealer's shop foreman drive mine while I rode with him over a spot I knew would cause the issue.  The result it he now believes me that there is an issue, that the door actually moves, I call it flapping basically.  It's like the door isn't latched.  He's stumped as to how to do anything about it though.  There's no adjustment, I feel like perhaps the door is not mounted correctly in the frame, and it only happens to some of the trucks.  My buddy has a nearly identical 2022 HC that doesn't do it.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      Progress... sort of.   Intake is disassembled, spider is out, fuel lines removed. Used a torch on the stripped screw with the lower intake off, much easier when I've got the intake sitting on my workbench, I made it talk. Walked right out with a pair of vice grips once it was nice and toasty hot.   New parts are piling up on my service cart waiting to be installed. Distributor, temperature sensor, new gaskets, fuel line kit, themostat, water neck.   My new pickle is I don't want to spend $600 on a replacement spider. I'm not sure IT is bad. I'm probably splitting hairs. Or it's $300 to send mine away and another 3 weeks of the truck just sitting. I have half a mind to assemble everything with the old spider to see if I can get away with just replacing the fuel pressure regulator to be safe. The obvious issue was the gushing high pressure fuel line which will be replaced. Getting to the spider really isn't that hard, and now I know what I'm doing , swapping it would be a breeze should it absolutely need one. Stupid, or smart?   The part that gives me pause is replacing the distributor. Well, it's already out. And I didn't mark it, whoopsie! Engine was at TDC when I removed it, I know that, so upon correct reinstall the metal tip on the rotor should point to the TDC mark on the distributor because that's where it was pointing on the old distributor. Worst case I'm a tooth off and have to re-stab it.   But then, what? I assume the truck will start. It doesn't appear the timing can be set. Here's the problem: These distributors can't be rotated but a degree or two, by design. What I read is Cam ****** needs to be -2 to +2 degrees, ideally at 0 (and checked/set above 1000 rpm). There should be enough wiggle to get that properly set, but checking the reported value is another potential issue. My Actron 9185 scanner says it supports enhanced GM PIDs and Cam ****** is one of them but it's unclear that I'll be able to correctly see it over OBD 1.5. I can see why people end up junking these things with life left in them. They're an absolute nightmare with tweener-year diagnostics/electronics and unobtanium parts.   Fingers crossed it starts and idles nicely. There can be hope, right? I'ma buy a lottery ticket the same day just in case.   Next steps..DO IT. I have not installed an intake before so I've been reading and watching a lot. Some say NO RTV except on china walls, some say DO RTV on water ports but not fuel/air intake. 1/4 or 3/8 bead on China walls? I think my strategy will be, obviously, RTV china walls with overlap on the gasket corners. Chapstick-style RTV the water ports. Leave intake ports dry. The only set of intake gaskets I could find locally are Edelbrock performance gaskets (uh...for an asthmatic 190hp V6? LOL) so we'll see how they do.   #NoToolLeftBehind. It took an hour, but my recovery mission for my deep 10mm socket was successful. It had rolled down the bellhousing and wedged itself between what I think are the fuel lines? I couldn't see it at all, but with a junk antenna I had laying around, I blindly went poking/sweeping for it, heard it clink, raised the truck, and caught a sliver glimpse of chrome with a flashlight way up there in Narnia. I had pushed it farther along the lines holding it captive, but within access of severely improvised tools, poking and cursing at it to finally knock it free to where I could get a fingertip on it to bring it home.    Not much to see.

      2027 GMC Sierra: Official Discussion

      It wouldn’t have happened if the government hadn’t mandated outrageous fuel mileage standards. It does very little for the consumer. It adds cost. Back during Covid there was a chip shortage. They gave a rebate for your truck if it didn’t have the chip to turn on cylinder deactivation. It was 50$ because at best you may see 1/2 a mile increase per gallon. Splitting hairs each fuel mileage trick wasn’t mandated. The government doesn’t do the engineering work and say use this until it’s already in use and they like it. The fuel mileage was mandated. And those add ons the results. There’s a mandate and they are the results.
