Does anyone know what the recall was for? I just got it 2 days ago for my 2024 silverado LT 1500. I read what up date was for, but didn't really understand what it was updating.

What was the recall #?  Should be like "N242435630" as an example.  Should show you in the update history/updates installed in the update section in radio settings.

I just got a message on my center display today, saying there was a pending update.  I think the number ended in 132.  It said something about updating for the low oil pressure indication.  

 

Does that sound like what you got, 15 z71?

Some GMC Sierra And Yukon Units Need An ECM Software Update 

By George Barta

August 22, 2025 6:06 am 

GM has issued a Service Update that applies to certain units of GMC full-size trucks and SUVs, including the Sierra, Yukon, and Yukon XL, which is related to an ECM software update. For GMC models, it applies specifically to the 2021-2024 Sierra 1500 and 2022-2023 Yukon and Yukon XL.

The Service Update, number N252510321, applies both to vehicles brought to the dealership by customers and to Sierra, Yukon, and Yukon XL units currently in dealer inventory. The involved trucks and SUVs are marked “Open” on their Investigate Vehicle History page.

 

Affected models need a software update to add a Driver Information Center (DIC) warning message to the existing Check Engine Light if DTC P0016 is set. If the necessary update isn’t applied, drivers may not be adequately notified of a potential problem that the Check Engine Light is trying to show them.

The fix involves reprogramming the Engine Control Module (ECM). Luckily for owners who have accepted the applicable terms and conditions, the necessary software changes can be made via an over-the-air (OTA) update, so they won’t have to bring their GMC to a dealership. For those who do go to the dealership for the fix, it should take less than an hour.

 

The fix is available free of charge to Sierra, Yukon, and Yukon XL owners through the end of the specific truck or SUV’s New Vehicle Limited Warranty period. It’s unclear at this time how many models are affected, but we know that only the aforementioned model years are affected.

The 2021-2024 GMC Sierra 1500 and 2022-2023 GMC Yukon/Yukon XL all ride on the GM T1 platform, which debuted when the current-generation Sierra came out for the 2019 model year. We’re expecting the next generation of GM full-size trucks to arrive for the 2027 model year, and their respective SUV versions should follow shortly thereafter.

When I brought my 22 refreshed Denali in for the L87 recall, they did the ECM software update.  #N252510321.

    • Whoever greenlighted the work truck matte black front bumpers on every trim but the AT4X should be fired!  I was hoping that was an AI mistake, but just realized they were on every model of the 2027 Silverado too.     Some parts of the interior do look premium, but the Denali Ultimate dashboard looks like an afterthought.  At least they appear to have lost the microfiber the high end Silverado models showed, but the '27 High Country dash looks better than the Denali.  
    • New member here. I am researching a read-first event-recorder concept for late-model GM V8 trucks. This is not a sales post. There is no product link, price, preorder, or mailing list. I am trying to determine whether the underlying problem is real before building anything.   Has your truck ever had a brief problem such as: - rough running or a momentary misfire - an oil-pressure warning or unusual pressure event - reduced power or a brief stall - a U-code or lost-communication problem - a symptom that disappeared before the dealer or independent shop could reproduce it   If so, I would appreciate the following details: - year, model, engine, and mileage - what happened and under what conditions - whether a DTC and useful freeze-frame data were stored - whether the shop was able to reproduce it - what the eventual confirmed repair was, if known - what additional information would have helped the diagnosis   The concept being evaluated is a removable leave-in recorder that continuously retains a rolling window from before and after an event. It would not tune, reflash, clear codes, or change the vehicle calibration.   I am also not claiming that it could predict lifter failure or see every internal ECM variable.   The real question is whether continuous event history would add enough useful evidence beyond freeze frame, GDS2, and existing scan tools — or whether it would simply be another unnecessary gadget.   For owners and technicians, which problem would make something like this genuinely useful: 1. intermittent misfire or AFM/DFM-related behavior 2. oil-pressure events 3. lost communication or electrical faults 4. none of the above Please be blunt. Negative feedback is just as useful as positive feedback.
    • No tears over the SLE and SLT trim levels disappearing but I kind of loathe the "Elevation" name. It's a truck--skip the elegance.   The slab-dashboard design is decidedly different. Almost has a Hummer flavor to it. "Professional Grade" seems to be leaning very white-collar, tech-driven these days moreso than blue-collar, functional design.   The Silverado would be my choice between the two new trucks. Pleased with the engine lineup in both. The GMC is a little "too much" for a truck, IMO, and the Denali borders on ridiculous - but I do know there are buyers for luxury trucks out there. It's just not my speed.
    • Your safety is of utmost importance, @joshua1221, and we understand the importance of having all your lights working in your truck. If you have not already, we highly encourage you to bring your concerns to the attention of your local GM dealer. They are in the best position to diagnose your concerns as well as confirm the compatibility of the mirrors with your truck. Additionally, we would like the opportunity to explore any way we may be of assistance.

    • - I like the outside but not as much as the Chevrolet.  They ICE'd the EV styling and it works, but I think exterior goes to Chevy on this one.     - SLE and SLT dead = Not.  Surprising.  Fits into the rest of the GMC lineup like this which (aside from Pro) matches the rest of the family.  Elevation, AT4, Denali.     - Interior.  Sophisticated Malaise era.  Why do I say Malaise?  Drawn with a ruler.  Rectangles everywhere.  Looks very premium though.
