I’ve seen a thread on here regarding this topic, but can’t seem to locate it. Anyway, I have a 2021 2500 HD crew cab and both my wife and I have noticed that the front doors rattle when going over bumps. I have read many posts about this issue with 2020-2022 HD’s. Apparently GM knows about this but has yet to come up with a solution. I called the dealership and they have no information about this. Does anyone have any updates regarding this? I’m just trying to avoid several trips to the dealership until a remedy has been found. Thanks

I never thought of that! I will give it a try.  It sounds like my back passenger door is also rattling

I thought mine was rattling but it wasn't, turned out to be the seat belt buckle (that wasn't being used of course) occasionally hitting the side of the door.

Problem Solved!! At least for me. 3 of my 4 doors rattled when going on rough roads. Talked to dealer body shop and he said he has not heard of this problem and that there is no door adjustment on those models. I decided to remove the door catch and attempt to bend it in slightly to see if that fixes the problem. As I was removing the T-40 bolts I found that the housing inside the body was lose. I then noticed that the catch housing has approximately 1/2” of vertical adjustment. I adjusted the two front doors as far up as possible and that eliminated the door rattling. Repeated the process on the rear doors and all is good!!! Easy fix and saved me several trips to the dealer.

Glad to hear the fix. Whenever I see a remedy I screenshot it and put all the pics in a photo album on my phone in case it happens in the future.

Thanks for the advice! I had rattling doors on my 2022 AT4 so I took your advice and moved the catch up as far as it would go and problem was solved.

Moving the catch up like this, did it not mess with your body lines? The gap from bottom to top between two doors?

It does change the gaps some, my truck is black so it's not too noticeable. After moving it up as far as it would go I dropped the catch down about an 1/8" on the front door so that helped with the miss match and it still makes the door close tight. I can live with the miss match but can't stand doors that rattle...

To adjust the door catch, do you have to do it from the inside of the door? Do I have to take my door panel off? My truck is brand new only 16,000 km  I don't really want to have to disassemble the whole door....

Hi I have a 2024 AT4 doing the exact same thing. 3 different Chevy and GMC dealer visits in San Diego and they all claim they don't know what I'm talking about. 

 

I the movement damped out with some electrical tape on the striker. 

 

I'm trying to understand what you adjusted when you say door catch. Do you mean the mechanism inside the door? Or the striker mounted inside the door frame at the b pillar?

The striker is located on the B-pillar, loosen the screws a bit but don't remove them and move it in the up direction. I ended up adjusting all 4 doors on my 2024 AT4. I put a piece of masking tape below the striker on the B-pillar before I loosened the screws, this allowed me to measure how far I moved it. I adjusted them all about 1/4" in the up direction and it solved the rattling problem. It does change the body line gaps because it lifts the door a little in the closed position but I really don't think it's that noticeable. Hope that answers your questions.

      Another 6.2L engine failure!

      By MASONV88888888 · Posted

      My 2025 Silverado 1500 had to receive a brand-new engine (long block) under warranty last month at only around 16,500 miles. Before the replacement, the truck repeatedly displayed "Engine Oil Level Low" warnings, even though the Oil Life Monitor still showed around 50% remaining after about 6,000 miles since my last oil change. After seeing the warning several times, I checked the dipstick with the engine cold, and the oil level was completely normal. The next day, the message escalated to "Add Engine Oil." At first, I assumed it was just a faulty oil level sensor, so I brought the truck to the dealership. After inspecting the engine, they found internal cylinder wall scoring and ultimately replaced the entire long block under warranty. Before this happened, I was planning to install a 4-inch lift and suspension upgrade on my truck. After needing a new engine at just 16,500 miles, I honestly don't see the point anymore. I also contacted GM to ask whether my vehicle qualified for a buyback, but I was informed that it does not at this time. Anyway, this experience has left me with serious concerns about the long-term reliability of this engine. I sincerely hope NHTSA expands the current investigation or recall to include 2025 model and performs a thorough inspection of affected vehicles. My biggest concern is that these engines may fail shortly after the powertrain warranty expires. If GM truly stands behind this engine, then at the very least, please consider extending the powertrain warranty to 10 years for affected owners. That would go a long way toward restoring customer confidence.

      OCI, not when but why?

      By Grumpy Bear · Posted

      Without exception but then I'm the odd duck, right? I know what goes into that test, how it is calculated and thus how to beat it. But EPA values are often not beaten by the general public and the government has in past years adjusted the means and methods to come to those values to more closely approximate "Joe Average".    The only real trick to beating that EPA average is don't drive like "Joe Average".    It's the same method you used to profit from "Economic Migration" and in doing so beat the 'stats'. But you, like me, are not "Joe Average".     The thing you don't seem to grasp is this "Purchasing Power Index" isn't forward looking. It doesn't predict what it going to be but looks backward and states what it was. They are not telling us what the THINK, they are telling us what they MEASURED. Example:    Wife says "I'm going to lose 40 pounds by Christmas". May she does, maybe she doesn't but the doctors office who weighed her when she made that statement and again at Christmas only REPORTS what the RESULT was. You and I can banter about what was possible and what aunt Tilly did till the cows come home but the result is the result. Arguing otherwise is.....irrational. That's all I'm saying. This isn't about:      What you are calling a 'Statistic' is a RESULT not a CALCUATION and as a result the RULE. Like gravity as a rule, it can not be broken.

      Rattle in the rear!

      By MASONV88888888 · Posted

      Just wanted to say thank you for posting this. Years later, your thread is still helping Silverado owners.   I bought my 2025 Silverado 1500 in January 2025, and I've had what feels like the exact same rattle since day one. After reading your findings, I believe my truck has the same issue with the cable carrier contacting the rear sliding window. To be honest, I had pretty much given up on pursuing the issue. It wasn't until I recently drove another brand's pickup that I realized just how quiet their cabin was—and how noisy mine has been all along. On my truck, the rattle happens on almost any paved road, gets even worse on rougher pavement, and I can even hear it during braking and acceleration.   I actually referenced your thread when submitting my case to GM, hoping they'll recognize this as a recurring issue instead of treating it as an isolated incident. The reason I reached out to GM first is because my dealership told me they would need to keep the truck for at least two days just to diagnose the problem. I was concerned that even after two days, they still might not be able to identify the source of the rattle before giving the truck back to me. I had also asked a few dealerships about this issue during previous service visits, but none of them seemed to know what was causing it or had a solution. That's why I decided to contact GM directly first, hoping they might already have an official repair procedure or guidance for this issue.   I also hope GM eventually comes up with an official fix for this problem. I have a feeling there are many Silverado owners experiencing the same rattle, but most either choose to live with it or simply don't know what the cause is.   Really appreciate you taking the time to document your diagnosis. Your post is still making a difference years later.

      Do you have access to BP fuels? Some stations have Silver 91 E-0 priced the same as their 93 E-10.  There is a local Marathon with 90 alky free for $6 a gallon but I go down the road to BP for $5-ish. They also have a 100 E-0 but that stuff is $10 a pop.
