2026 3500HD 6.6 gas.

Happened a few times now .

Radio works fine, then stop and shut off truck. Come back 20 minutes later start truck, no sound. I'm sure the dealer hasn't a clue or can't replicate.

Ideas?

BTW

My 23 High Country did similar things. Like go black while you're driving.  No sound no nothing. Then it would come back on after a minute.

Things like this piss me off they know there's a problem but just keep using the same schittty part until the next generation because it's easier to find new buyers than keep long time customers (47 years, 23 Chevy trucks, most were new) like me.

Yeah my ‘24 ZR2 was a bit twitchy, sound cutting out, etc.  seems like this has been an ongoing issue since maybe 2023.  I saw that some tried replacing the amp at some point but it did not solve anything

Are you talking Sirius radio? As you can see the station, song and artist but no sound? Also, no sound from either AM or FM bands?

Press and hold the mute/call hang up button on the right steering wheel controls for 15-20 seconds.  That hard re-boots the radio.

 

If that doesn't solve the sound issue, there's likely an update the dealer can perform.

The more technology the more unreliable things seem to be getting. 
 

no issues at all with my 22 radio but it’s on the older technology.

Only thing that works is let it sit for a while.

If it keeps doing this it's going in to the dealer.

The hard-reboot has worked for me. I hold down the hang up button  while the screen clears and continue to hold until it comes back on. I probably need an update as I’m still showing the I’m running Android 10. I don’t have On Star so I’m guessing it would need to be Dealer installed. Don’t really want to part with the coin to have it done. Do I even need to?

Radio updating is covered under Bumper 2 Bumper if you still are in that 3yr/36mi period.  You'd just have to express one or more of the concerns in the current radio update bulletin and they'd be able to flash it.  

 

GM doesn't track the software via what level of Android Automotive it has, rather, they track it based on the build number.  Y181 is the latest and greatest software.  Example below of the page with the prior build Y177.

My build date is Y169.3.2 so I’ll give the local Dealer a call.

 

Thanks very much.

So I have had this happen twice now. First time was a short stop with about a 20 minute off period. Next restart it was fine again. Sunday it happened but this was after the truck was off for over 5 hours. Did the hard reset and it was fine. Wonder if more then just the few of us have been having this issue. My truck is out of factory warranty and really don't want to pay the deductible just to have an update done.

Had the same issue multiple times.  Dealer could not replicate, of course, so nothing was done.  At least its documented for whatever thats worth.

Had this happen to a few times. No sound at all, including turn signals. Reset via the hangup button on the steering wheel cleared it up.

      Correct way to service 2024 l8t allison trans?

      By Chuck FB · Posted

      That should answer the maximum depth difference between the stock and the PPE so its not hugely lower. As to the PML pan, they don't make any claims that it fits the L8T with the same transmission and in fact leave their information confusing, however on the surface it says "for Duramax" and so its hard to say. I know a while back and not sure which brand it was that specifically stated that the extra capacity pan that particular company made did NOT fit the gas version.

      Installed Bilstein 5100's on my 2024 2500HD - Worth it - VIDEO + GIVEAWAY Inside

      By fondupot · Posted

      There are several versions of the 5100's. Some for stock height, some for leveled, some for lifted.    Side note. I finally had a chance to tow with my 30' gooseneck with about 10,000 lbs of material on it this past week. Hands down the 5100's made the trailer towing much more stable and comfortable. I even had 10 cmu blocks in the bed. What a difference over the stock shocks.

      According to PML, the stock pan is 4.3" deep - (PML info): Dimensions: at deepest area, PML pan is 7 inches, stock pan is 4.3 inches    PPE is 5.4" so roughly 1.1" deeper than stock

      I had not realized that PPE has come out with a version of a cast aluminum oil pan specific to being able to fit onto the 10L1000 with the L8T engine sometime this spring. I was doubting that anyone would come out with something beyond what Dorman had in more of a direct factory pan swap. I see from one comment that is on the PPE site that they found the pan to be tighter to install then the factory unit and having to flex the exhaust down to fit it. I didn't lookup any specs if they have any as per how much lower it hangs but as it holds more oil and has fins outside the pan it would no doubt hang a certain amount lower.    I looked back at the site and they do have some depth measurements to get a rough comparison to the factory pan total height or hang down if you will at the front and rear of the pan so that will give a good idea how much further down this pan would end up being for ground clearance issues.    2024-2026 GM 6.6L Gas 10L1000 Heavy-Duty Cast Transmission Pan – Pacific Performance Engineering

      I'm in constant amazement over the number of people that do oil maintenance by how they feel, what they were told, what materials cost, what brand A claims vs brand B.     Come to think of it, this behavior isn't exclusive to oil. 🤔 They drive this way too. 😬   There is a 20 plus page thread on BITOG on Mobil 1 Advanced Clean vs Valvoline Restore and Protect it would be amusing if it were not so........humanly pitiful.   Last Sunday we were are sitting at services and listening to a speaker talk about Jesus parable of the wide and narrow gates and he said something that hadn't dawned on me but totally fit the way people in general are about just about everything. He said there are so few people on the narrow path leading to a good reward not because the the narrow gate was hidden or hard to find but because the wide gate leading to a bad end it so darn easy and uncomplicated to follow!!!
