Hello everyone:
Got in my 2024 C8 Z06 this morning, backed out of the garage and I got a message to download update. Has anyone else did this update right from the car recently, or is this something that needs to go to the dealer?
I had an OTA update pop up 2 days ago. Should be able to go to Home, settings, updates, check for updates and it will install. Have the car outside if it hasn't downloaded the update.

Recommendations: Drivers window down, smart charger installed, frunk open before you start the OTA. Occasionally some OTAs have hung up and drained the battery. Doing these steps minimizes that risk.

My early 24 called for it when I drove in the garage 2 days ago. Only took about 5 minutes. Follow the prompts.
Battery tender back on after.
Have no idea what the update was, but my car is much faster
The notes said
Improves frunk latching in cold
improves range accuracy in shuttle mode
Improves check engine light accuracy
Improves center display adjust to ambient light change
Improves warning when key is missing
improves tuning for interior lights in stealth mode
Improves auto low beam logic
Improves AWD notif (prob not a vette thing)
Also check with the dealer but there is a BCM update to reduce the chattiness of the BCM and Improve MIL light detection ranges and a few other things. This one has to be done at the dealer or with the subscription tools to download module updates
This is the 2nd OTA update I've gotten since I bought my Z06 in 2024. In both cases, a key indicator of a needed update would be that the radio would continue to play, even with the car off and me leaving the car. It would typically play for a minute or two even as I walked away from the car and the car auto locked the doors.
After the first update, this behavior stopped and the car would operate normally - the radio would turn off as soon as I opened the door.
After THIS update, the radio issue did NOT fix itself. It is back to staying on after the engine is off and I've left the car. I hope this eventually takes care of itself????
Have you tried the Cache clearing exercise? I think its procedure is on Youtube but basically is shut off car open door and leave it open for at least 60 secs then close and restart / shut off. I am sure its on this site or a quick you tube search will find it

I called the dealer a few weeks ago about a different issue and he told me their was a BCM download that has to be done

‘I heard there was some issues on 2022 C8 with the updates with battery draining, but haven’t heard about that issues on 2024’s?

I do not recall specifically it happening on a 24 or newer, but it did not appear to be MY or model specific in any of the prior postings. I have a 23 Z06 and have not personnally experienced it, but did take the precautions I listed above when I did them. They are easy enough: an ounce of prevention is worth a pound of cure. (old saying), may be new to many Corvette owners.

‘Can I just not do the update, in other words don’t pay attention to it. I have to go to dealer for a hard BCM download anyway, let the dealer handle any other updates.

Why ignore it? The instructions on how to execute the download is as simple as hitting a button and waiting for a few minutes - Unless you have a more complex issue?
I would just do it - I have a 24 and there's been 2 updates that I can recall and were both simple to do. Good Luck!

You’ve got 45 days. After that, any issues needing repair relating to outdated software will be billed to you.

GM has fixed the issue and your 2023 MY should have the gateway module TSB issued that fixes it( and earlier MY's).

‘’I will do the download, it may be the BCM download, of which it will kick it out and fail the down load.
I’m sorry but I don’t believe gm can enforce this download or else…. Day one I turned of OTA’s on my SR and now my Z06. If the car is running fine I’m not messing with it or letting gm mess with it while it’s in my garage… there have been several examples of OTA’s going wrong turning customers vehicles in “lawn art”. If the car needs repairs I’ll bring it in so if the “update” drains the battery or causes some other unforeseen issue, it’s the dealers problem.
I also don’t believe the “update or else” rule will hold up if the lawyers get involved but regardless if gm wants to play that game I’m more than fine with dumping the car and getting an AMG GT or something else…. My daily is an AMG that has also never had an OTA… six years a counting no issues.
Auto manufacturers leaning on OTA’s concerns me they will deliver vehicles that have not been properly vetted and debugged.
I don’t see how GM’s statement about “you must download within 45 days…” can be enforced…. I don’t remember home wifi as being a requirement for Corvette ownership. What if owners use a detached garage that even though they have WiFi the signal doesn’t reach where the car is garaged? Or what if the vehicle isn’t garaged at all? There are so many holes in the “download or else”…

That would be my approach. If the car needs repairs I’ll bring it in. I have OTA’s turned off in the vehicle settings menu. I did the same on my SR and never had a problem and never received any notification of a pending OTA.

I agree. The article states, "General Motors provided the following statement regarding its policy. "As standard industry practice, most automaker warranties require owners to follow the recommended maintenance schedule to keep the vehicle in proper working condition," the company said. "
Yet, software updates are not listed anywhere in the recommended maintenance schedule outlined in the owner's manual.
Further, Chevrolet.com states this about OTAs, "
To be eligible for vehicle software updates, including automatic Super Cruise®* driver assistance technology map updates (if equipped), you must have accepted the connected vehicle User Terms for Connected Vehicle Services and OnStar Privacy Statement for the vehicle"
There's nothing forcing the owner to accept the connected vehicle user terms & privacy statement as a condition of the new vehicle warranty.
I’m sorry but I don’t believe gm can enforce this download or else….
A warranty is what a manufacturer decides is a warranty. As long as it’s stated by the manufacturer, then it’s enforceable. That’s why some manufacturers offer a 3 year Bumper-To-Bumper (Chevrolet), while others offer a 4 year B2B (Cadillac), and some offer 5 years (Kia, Hyundai). A B2B could be 2 years or even 1 year, as long as it’s stated (the consumer pretty much expects 3 years minimum for B2B so anything less would most likely seriously hurt sales). Some offer 5 year Drivetrain warranties (Chevrolet, transferable) and some offer 10 years (Kia, Hyundai, NOT transferable). Some include one-time free maintenance (Corvette includes one oil change and one DCT filter change, must be completed within stated time or it expires), while at least one manufacturer includes 7 years of oil changes plus other free maintenance for 7 years (Ferrari). Whatever the manufacturer decides, as long as it’s stated, is enforceable.

I’ve had several OTA updates work fine with my 2020 C8 which I owned until DEC 2024. Same for my 2025 Z06. Never had an OTA issues. Just because a small number of C8 owners had an issue, doesn’t mean everyone will have an issue. Also, OTA updates include updates/fixes that newer C8’s include. If the GM software engineers include those fixes in subsequent model year Corvettes, I want those updates/fixes too. One example is my 2020 C8 did not include a reminder when a phone was left in the charging cradle. Sometime in 2021 I received an OTA update that added that feature.

You’re free to purchase whatever you want.

Software is never perfect, there are so many lines of code, often millions, that there are bound to be issues. Microsoft, Apple, etc are always creating software patches. One example would be software hackers that are always looking for ways to break into your computer (or car’s computer!). Sometimes they find a way then Microsoft and Apple create software patches that “close the door” on viruses that can disable your computer. Refusing to install those software patches can leave you’re system vulnerable to getting hacked and viruses.

Not sure what home WiFi has to do with anything. C8 OTA updates come via 4G cellular, no WiFi required.
