I received a call from my gm rep today asking how my repair went. Funny thing is I've never heard from my dealer that my parts had arrived!! I'm selling or trading mine asap. Maybe back to a 2wd is in my future. Can't bring myself to buy another brand of truck. This is pitiful!

I’ve considered going to a 2500 if they can’t get it figured out. Haven’t heard of the HD having the issue

I think if you look up the SU5 Axles don't have this issue, only the SU4s.  I've been doing some research and trying to find out which models have the SU4s or if it just depends on where the truck is made.

Mine was built in Indiana.  If you go look at them and scan the barcode on the B pillar you can see the build code.  I'm going to make sure when I get rid of this one that it doesn't have the SU4 axle in the new one.

I hope you're right but I would think that if the SU5 didn't have the problem that GM would simply just change out the axles to the SU5 as the fix

The axle has nothing to do with your VIN. 
 

The VIN tells a few things about configuration (nothing about axles) and where the vehicle was built by who.

It’s tied to the build codes that are on the door. I think those are related to the vin number. So if you took your truck to another dealer that didn’t know they replaced your axle with another and they pull your vin from the system it’s going to show the old Axle based off their cross referencing the build codes. It wouldn’t change your VIN but the link your build codes would be off and they wouldn’t know what parts to use.

GM will send your the build sheet for any gm vehicle if you ask them and it will pull all the options based on your VIN. So the trucks with the problems are SU4 build codes. That’s what will show up in the system. I don’t think they have a way or want to change the build codes on a vehicle because of that.

It’d be in your file no matter what. 
 

the RPO codes just represent what the vehicle was built with. They don’t change after that but might mean nothing 20 years down the road.

My dealer just called to let me know that my stub shaft is in. It's already been changed twice, I don't know why they think changing it a third time is going to remedy anything. I clearly told my GM rep that I refuse to let them change it again and she agreed. That was over 2 weeks ago and now she won't return any of my calls. This is my 4th GM truck and it will definitely be my last. This has been nothing but a nightmare.

Don't know where you live but here in Wisconsin if they fix the same thing 4 times and still doesn't fix the issue or the vehicle is not operable for 30+ days, it can be lemon law'd. You'd have to look up your state laws to determine what they consider lemon law. I'm waiting for them to get the axle shaft, its currently on back order. This will only be the first time they'll have replaced it. But if they replace the shaft 4 time before a real fix is found out, I'm lemon lawing the truck.

So, another victim to poor design. I started having this issue at around 6,000 miles. I have a 2020 RST z71 with those SU4 axles. Found this thread and finally can move forward with potential fixes. Looking at building a case to lemon law the truck. Working with my local dealership, I was floored they couldn't get this right. I finally found the PIP that "GM says fixes" the issue. Hoping it actually does, but after ready 30 pages of this thread, I think I'll end up in the same boat. Ohio has a one year or 18,000 mile lemon law. So far I'm at 10,500 miles and have until March. This will be the third repair, so hopefully I will have time to lemon law if it doesn't fix it.

In Ohio, the first repair attempt just has to be done in the first year... you can start lemon law after a year as long as the issue started and repair attempted before the first year or 18k... i'm in the same boat, on my 2nd repair attempt now... 1st attempt was last October, was quiet until late July or so and started making noise again. took it in late August to be told they were waiting for a new repair, now parts are finally in.

Thanks for the info, I read over it quickly. Hopefully it will fix it. I don't want to have to go through the process of buying a new truck if it comes down to it, however, if it does end up going down that road, I will probably buy a 2018 and get a few more options for less $$ used.

Hi,

I had the same noise that started around 5k Miles.

its the FR L. Drive shaft that goes into the diff that makes that noise.

i noticed whenever the suspension traveled in or out it stopped making that noise. 
so I decided to lift the truck and see what happens!

guess what the sound is Completely goneCompletely gone

so I suggest you all buy a 40 inch lift kit from ready lift and the sound will go away

So GM finally made an offer. A horrible offer. Let’s give you an additional 24000 mile warranty. Yeah, NO. So I can have it back at the dealership every 50 miles!

This madness needs to end. So sick and tired of the issues and the pure lack of customer service.

Will NEVER own another GM product again.

    • I’m definitely interested to hear the end result here. 
    • 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.
    • 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. 
    • 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.
