It's back... after a getting the original repair done in late 2019, the jingle has returned.  went on a road trip from jersey to maine and on the way back i heard the familiar sound.  even the girlfriend confirmed.  time to take it back to the dealer for this and the shitty 8 speed.  the noise is a little more random than it was before, but it definitely stopped as soon as i shifted into 4 wheel auto.  not much hope after the trouble they gave me the first go around... im just about very much so over this truck.

It's a well known issue and GM keeps producing the vehicle without a design fix. I have a 20' ltz 6.2 fully loaded with the same issue. GM as of my recurrence in July will not even attempt a fix until another "fix" is approved. The 21' was produced with the same design, so I imagine they will continue to produce this design until people quit buying. The refusal to fix until a enineering solution shields them from the lemon law.

Are TrailBoss and AT4 owners experiencing this same problem?  Or is it only on trucks with standard ride height?  TB and AT4 have different CV shafts, right?

 

I'm finally in the market for a new truck and have my eyes set on a new AT4.  Just wondering if this is something I have to look forward to?

This issue only effect trucks with the AAM front axle (SU4) the axle made by GM (SU5) doesn't have the issue. You can tell which axle you have is by the build code or get under the truck and look at the front diff gear housing on the passenger side of the housing you will see a raised embossed stamp that has the GM Mark of excellent logo on the housing towards the top this is the SU5 axle, pretty easy to see with a flashlight.  The AAM axle (SU4) is an outside vendor who makes the axle for GM which has the jingle issue. The SU5 is made by GM that does not have the jingle issue.

SU5’s have reported the issue in here. 

 

I pretty sure its only the SU4s that are affected or GM would of included the SU5. That's just my opinion...

Thanks for the info.

 

I hope everybody gets their problems fixed "quickly."

Dealer had my truck for 2 days. Drove it a total of 90+ miles and could not duplicate sound. They were stumped because I sent them this video as proof... They are an awesome dealership and do everything to help me out so cant wait to go back to them with this TSB. Here is the video that captures the sound pretty well, I notice it most on hot 80-90 degree days after driving for about 30-45 mins...also tested pushing 4wd auto and it goes away. Has anyone had this successfully fixed?

Don’t get your hopes up. I bought my truck in April of 2019, first reported the issue in may/June of 2019 and was told the dealership was waiting for a repair from GM. Finally got the truck “fixed” in September of 2019, fast forward to this past month, and the issue has returned. GM has had over 2 years to figure out how to fix the problem, I have zero confidence they will do so at this point. Sad thing is they continue putting an axle in brand new vehicles two model years later, knowing full well that it has this issue. Shame shame.

Hey does anyone know if this is happening to 2021? I'm pretty pissed I have a 2019 Denial after 15 YEARS of driving my prior truck I finally upgraded and now I can't get in without hearing a squeaking noise. I'm close to pulling the trigger on a FERD but I love the 6.2 and Denali trim. Anyone know if the 21's are experiencing the same thing? 

 

Also my front driver side tire has been thrown out of balance multiple times, so their claim "does not damage the ride" is BS.

 

Thanks

Doesn't look good. I drove 100 miles yesterday and I could hear the chirp and then hear it even louder when it bounced off of other cars going by. Some of us are hoping guys like you with higher end vehicles will help push things along. It's nuts to me there isn't a fix yet. They have tried in the past, so I'll hold out hope they're still trying. I love the truck. Baby Duramax here.

According to the service bulletin PIP-5653K, 2021 Sierra and Silverado 1500’s are included. I guess the only way around it would be to ask for a build sheet from your dealer and make sure it has the SU5 axle rather than the SU4 before you buy. Still deciding what I should do with my 2019

    • Wawa and Meijer here have ethanol free (88 & 89) I use for my mower and lawn equipment.  Its not much more than reg.  I paid $3.29 a few weeks ago.  
    • tl; dr I've now reached the 6th floor of hell. I'm chronicling my journey for my morning readers.   Pulling the top of the intake apart was moderately easy but it involved a lot of parts, connections, and minutae. I was preparing for the new fuel lines to arrive ("nut and bolt kit" it's called). The fuel line connections are notched and held in place by the manifold and a metal plate with a T27 screw.   It's on the back of the intake, under the firewall, with little clearance, and two hard metal fuel lines in the way. I was using Franken-tools (weird combinations of 1/4 inch ratchet with/without an extension, with a bit holder for my T27) to get in there. One of my sockets and bits fell off and has yet to emerge on the floor. I lost a second setup and that's when I almost started throwing tools. But that was the point at which I had gotten traction on the Torx head, and it promptly stripped. No more traction.   I started humming "1-877-kars-4-kids" because I was about at that point. You know what? I'm $1500 into this thing and I can make it disappear just as quickly. This isn't fun anymore. I had spent a lot of time already "tidying" around the engine bay: Fixing all the "someone's been here before!" BS. The truck has been exclusively dealer- and shop- serviced and I'm reminded of why I never let other people work on my cars unless absolutely necessary.   Speaking of dealer service. This truck has a 1" stack of records going back to 1995. I put them all in an excel spreadsheet, date/mileage/description.   The CPI spider has been replaced 4 times in 85k miles. The EGR? Another 4. Multiple, multiple O2 sensors. One Cat. 4? Sets of plugs and wires, and I swear half the stack is diagnosis paperwork for "misfire, runs rough, extended crank, dies at stoplights".   GM was producing some proper crap back then. And it was still well within the era of brittle/crappy plastic. (Windows 95 was released the same month this truck was sold new, we HAD the technology!!)   There (was) a plastic shroud around the evaporator core and HVAC fan in the engine bay. I noticed a chunk of it missing so I poked at it some more and it literally shattered. Touched it some more and pieces were crumbling off. Had a good laugh. Clearly whatever plastic garbage they were using had broken down over 30 years and was literally turning to dust. That was a good half hour of using a shop vac to remove the rest of it.   Back to it.   I was going to give up for the evening but then decided I'm already level 10 pissed off at the stripped screw: G* D* it, give me my tools back -- and my JOY. We'll do this the hard way: The whole intake is coming off.   Blazer won Round II. After finally finding and accessing the 12 intake bolts and using a pry bar to unseat it from the heads, it popped loose in an explosion of gunk and grime raining down into open ports. Awesome.   6 times I reminded myself: Be careful of the temperature sender on the front of the intake.   YEAH, I forgot again and snapped it clean off in the removal. Add another $20 to the ever-growing list of new parts this thing is consuming.   The shame is, long before removing the intake, I had changed the oil in prep for Tuesday's momentous fuel line replacement that was going to be the magic fix and I'd have a running Blazer to tool around in this next weekend. The intake removal, including raining gunk, also gushed dirty coolant all over the valley. Of course it did. Welp, there goes another $35.   I now need an intake gasket set, bolt set, coolant temp sensor, another 5 quarts of oil, some RTV. Don't worry, I've already got 3 new jugs of Dexcool and a thermostat waiting. I'll fill it with clean water first to get it running, dump it, and then add the Dex later on in case... well, let's not go there. I'm only tearing this down once, next time the truck is going on Marketplace for FREE.   Oh, and I'm going to need vacuum hose for all the stupid connections placed at the rear of the engine which have since disintegrated. Come on, GM....tell me you don't do that anymore?   Oh, and the ears on the distributor where the cap screws down are both cracked. I mean, why not put a new distributor in it too. You get a distributor, YOU get a distributor, Everyone gets a new distributor!   This truck isn't out of the woods yet...I'm already questioning how much more time I'm willing to sink in.
    • NewDude, thank you for the suggestions!    I did follow up and the dealer indicates he has an open CX case and is working with DPAC (Dealer Parts Assistance Center).   Per the dealer, GM has had a quality spill and is not providing an update for when a replacement engine will be available.
    • That's interesting.   There was a factory wire-hole in the back, top of the rear cab, which had a wire for the third brakelight assembly running through it, as well as several holes (10 of them I believe) for all of the studs coming off of the 3rd brakelight assembly itself.   I sealed all of those holes with RTV/silicone as well.   I found it kind of odd, that none of those holes, were sealed with any kind of sealant by the factory - if there was any there, it wasn't very much.   That said, I've been out in heavy rain and have ran the truck through high-pressure car-washes a few times now and she has been 100% water-tight to this point.   I feel very confident in the repair, we'll see how it holds up.
    • I bought a used 2022 2500hd with 6.6L in February. In March took a 2200 mile trip towing our 6500 lb trailer. Changed the oil day before leaving and when we were arriving at our 1st destination, low oil light came on (roughly 1000 miles) it was 2 qts low. Now it towed like a dream, no issue there, and we did go through the mountains of TN, but still, 2 qts! Luckily I did purchase an extended warranty. Brought it to the dealership in April, oil change and consumption test. Brought it back last week, 1300 miles, no towing, and no oil showing on the dipstick. GM is reccomending a new engine (cheaper than them rebuilding), we'll see if the warranty company comes through.
