So, got off work, hopped into the truck, started up... no radio, no audio of any kind. Tried the "hold end call on steering wheel for ten seconds", no luck. Called dealer service department, guy said "Huh, yeah. Disconnect negative terminal of the battery for 5 minutes, should fix it." What he didn't tell me was that when you do that, and then reconnect the battery, the horn alarm starts going off. WFT?? Does this happen enough that the service department tells you to "disconnect the battery for 5 minutes", even if you don't carry tools in the truck?

 

Got the alarm to shut off. However, my question is how often does the truck's audio (radio, phone, alerts, etc) just randomly shut off? Tried to call the wife... nope!! No audio at all.

 

Yes, I realize the truck is still under warranty, however, the engine issues seem to take priority.

My truck did this one time. I was able to correct the issue by turning off the truck and letting it sit for 10 minutes. Restarted the truck and have not had any more issues.

Mine did this once. Went to dealer and they fixed. Had to reboot the radio system.   According to the tech that did it, common issue with the current system (took about 15 min). 

 

A friend said Onstar fixed his.  I tired but the Onstar tech did not speaka the good English and I had to hang up because I could not understand him. Very frustrating, he was getting po'd at me because I kept telling him I can not understand you!

This was the third time for me. First two the dealer "supposedly" took care of it by reprograming modules. Now I wonder if I will be left hanging with no connectivity with an $85K truck.

This happened to me for the first time yesterday.  No sounds at all, no radio, no door chimes, no turn signal beeping, etc.  The next time I started it back up all was fine.  I'm not even sure if it sat 10 minutes between issues and restart.  I didn't panic or worry because I've heard this was a known issue.  I suspect something in the computer system isn't launching or starting at start up as it should.

Might need a new radio.

 

There are specific steps a dealer must do to get one shipped in.  

 

Of course it's also possible the steps might correct the problem

Required Information for Restricted IOK Radios

May 13, 2025

The infotainment system (RPO IOK) on 2022-2025 Silverado, Tahoe, Suburban, Sierra, Yukon, HUMMER EV; 2024-2025 Corvette, Silverado HD and Sierra HD models is on restriction. (Fig. 3) If the radio must be replaced, there are several procedures that must be followed to order a new radio.

The IOK Radio part numbers 85086705 and 85086710 have been put on restriction based on #PIC6602. A PQC case will need to be created prior to ordering the part through Specmo. The PQC phone number is 866-654-7654.

Required Information

PQC will ask for the following information when creating the case:

  1. What is the message displayed on the radio screen? See #PIT6209.
  2. Did the technician confirm the radio software is up to date following:
  • Bulletin #24-NA-261 – 2022-2024 Full-Size Trucks and SUVs
  • Bulletin #24-NA-276 – 2025 Full-Size Trucks
  • Bulletin #24-NA-168 – 2022-2024 HUMMER EV
  • Bulletin #25-NA-098 – 2024-2025 Corvette and 2025 HUMMER EV
  1. If the radio is not at the latest software level, did the technician update the radio, clear all codes and recheck for the concern?
  2. If concerns continue, did the technician disconnect, inspect and reconnect all related connections, clear any codes and recheck for the concern?
  3. What is the current as-built version for the radio?

Once the PQC case is created and the part is released, dealerships can reach out to Specmo to order the radio. Specmo is the only approved supplier of the part. They will verify the PQC case and verify the part can be shipped.

Refer to #PIC6602 for additional information.

Thanks for the info! 👍 You gave me the first breadcrumb to follow. LOL

 

While searching for #PIC6602, I also found #PIT6101Q which says

So, I'm going to see if I can check the software version or I might have a bad/intermittent amplifier.

You're under warranty.

Take it in and let them provide the service you already paid for. 

 

If it needs a radio, they will have to go thru the steps anyway.

    • This is a 1/2 ton thing ONLY.  All HDs 2020-2026 have the two speed transfer case, with Autotrac as an option.     1/2 tons 2019-2026, regular 4x4s come with a single speed case (no 4LO!), and trucks with Z71 ordered, or all Trail Boss trucks come with the 2 speed case.  2 speed case is also an option on WT, and is also standard on High Country.  
    • 2013 5.3 still to this day calls for the PF48 filter.  Which as a 15psi bypass pressure.     There is a TSB, 17-NA-157 that talks about the PF-63 and PF-64 filters which have a higher bypass rating of 22psi.    TSB HERE - temp.xml   "Beginning in 2012, the oil pumps began to regulate main gallery feedback instead of pump out pressure. This means that the oil pump now does not begin to regulate until pressure is built up to the main gallery. This change reduces the amount of time it takes to provide oil to the engine bearing and lifters during extreme cold start conditions.  Main gallery feedback oil pump control systems are present on the following engine families which use Spin-on oil filters: Small Gas Engine (SGE), Large Gas Engine (LGE), High Feature (HFV6) Gen2 and Small Block Gen5 gasoline engines. These engines with the main gallery feedback oil pump control systems are factory built with an ACDelco® oil filters"   It also calls out what engines use those filters.  The gen 4 small blocks were not on that list (LMG, LC9, L9H, L92, L94, L20, L96).  Gen 5 small blocks use the higher pressure filter.          That all said...   Your 7045 Napa filter is the PF63 equivalent, with 22psi bypass.  You are already using the higher bypass pressure filter.  You CAN keep using it, you don't technically have to use it though.  
    • Do you know WHY the filter relief setting was increased to 22 psig?    When the new system goes into the second stage the pump volume ramps up considerably. It was found that the 15 psi filter bypass setting put the filter in bypass on a warm engine when the second stage was activated. Raising the filter bypass setting forced the filter to do what it designed to do. Filter. Preventing debris from circulating during high load, high rpm operation.    So next question is how did GM find this out? VLOM/lifter failures and a deep dive by Melling Corp.    Last question. Is it required? Look at it like this; a motor may be equipped with a rev limiter. But it only works if the set point in reached. That 22 psig setting only matters if the pressure differential across the filter media exceeds 15 psig during normal warm operation. Second stage kicks in around 3000-3500 rpm.    I can't answer your question because I don't know you and how you use the truck. But I think there is enough information here to let you decide for yourself. 😉
    • Probably not their first rodeo, so it should go as planned most likely.  Typically the service manager or tech doing the swap will put some seat time to shake it down after they get it all put back together.  We usually put 50-100mi before we hand them back so if something happens, its not after you get it.  A coolant leaks, oil leaks, a ground left off or loose, vibration, etc.     The new engines so far have been good?  There's been a couple that have popped out there again (the replacement engine) but most have been okay.
