There is no reason not to get this update. It only takes approximately one hour to complete. Without it, I don’t believe you will receive any over the air future software updates.

 

I don’t need or want any updates. My car runs perfect. I don’t want an issue like corvette gear head.
JUST SAY NO👍

 

And now today since it was on dollies when they moved it, the front wheels slipped off of them and the dollies broke the front bumper. So they will be replacing the front bumper and color matching it. It keeps getting worse.

 

Updates can be fixes for problems. My 22 got one for the instrument display going black at startup. It didn't happen again after the update.

 

I guess if I had a problem I'd be willing to get it done..... as my '23 is just peachy why should I? What kind of updates have folks been getting? To update what exactly?

 

Even if and when they (GM) provides a description, it typically cryptic - very high level statement. And even if it seems like something clear, you never know what other changes have been bundled in with the change. I think I have seen reports of a subtle change in the behavior of a feature, such as the way the driver modes defaults, after an update - but that change was never mentioned in the description. I'm not saying GM is being deceptive. But its like when you get a system update on your lap top (mine was recently in the shop) and when it comes back it acts differently. They don't really articulate all the details of the change.

 

So assume you had that update done..... on the fence....but otoh, the improper installation incident is probably very unusual....I won't be going to a dealer for some time tho...6 months for a tranny fluid change out (3 year) if I don't decide to do it myself.

 

You know GM can reflash your ECM on an OTA update to detune your car to a lower power rating. This is a possibility and could happen for a few reasons.......

 

No I have not had this recent update done. I have a 2021. I have had OTA updates in the past, without incident, but I received no notice about this one. If it was done, then it was done without my knowledge while it was in for Service.

My statement about changed behavior was from reading other posts. Some car default to Tour when shut off in Sport. Others would stay in Sport when shut off in Sport. I think I have read that the default behavior for some changed after an update. I won't be able to find those posts - so its memory only.

 

No offense but I would strongly advise against the update for anyone that has disconnected your vehicle from GM's online services. You don't get OTA updates anyway, no risk to the issue.

Unless you have disconnected your GM online services, General Motors (GM) steals (aka takes without your permission) and shares your driving data with LexisNexis, a data clearinghouse that distributes information to numerous insurance companies. You are entitled to request a report of this data (as I did), which details every time you’ve exceeded 80 mph, each instance of “hard braking,” “hard acceleration,” and more.

This is not comparable to the optional data you might share with mobile apps like Waze or Google. (As a software engineer, I can confirm that Apple Maps does not collect or share your driving data.) This isn’t a conspiracy theory—it’s real. For example, my wife’s 2019 Jaguar SUV had data actively flowing to LexisNexis for years, resulting in a 30% higher insurance rate than my new 2023 C8 Corvette, despite the Jaguar being significantly less expensive and older. Why would a newer, high-performance car like the C8 have lower insurance rates than an older Jaguar SUV? The answer seems to be tied to data sharing and insurance profiling.



I also recommend using an OBD port lock. When my dealership insisted on accessing my car’s OBD diagnostic port as a prerequisite for replacing a faulty roof grommet (under warranty), I declined and purchased the part myself instead.

 

Here is the link to use to see your warranty coverage and any recalls against your GM product. Just put your VIN number at the end of the link (no spaces!) before you use this link in your browser:

Or just go to the base link and enter your VIN into the form:

https://www.chevrolet.com/ownercenter/recalls

 

This recall update is to prevent batt drainage.... I've never had an issue so....?

 

I called this number to check several things:
1. My extended warranty wasn't listed with my VIN - they said that would only be available at a dealership (confirmed my dealership shows the extended warranty).
2. My car was back 11/12/24 after 6 weeks for some issues that included the serial gateway recall work - the service paperwork shows it is done, but neither the recall URL above nor the car DIC show any update.

The representative said it is possible the recall work (which does not show on her screen) will be updated by dealership later.
But it doesn't make sense that the car's DIC only shows build info from 2022 (it's a 23 HTC).

Will wait and see why the recall info is not showing on my DIC

 

Took my 2023 in on Monday for the recall update and center console button replacement. All went very smooth. They had the car for a couple of hours after I dropped it off. FWIW, I don’t do any OTA updates, never have and no desire to do so in the future. However, I will take it in any time they issue a recall. Mainly because I don't want to risk anything that could void the warranty.

 

So....has anyone reported that this ever shows up in the DIC as and update? I don't think this "update" is the same type of update that can be done OTA. This is a "re-programming" of the Serial Data Gateway Module. The procedure for reprogramming of that module, described in the Service Manual, is pretty involved.

The description of the process, found in the announcement at this link, looks similar - very involved. So, I don't think is the regular type of update that is going to show up on a DIC. It may, but its a very different process.

The 800 number above confirmed 'no outstanding recalls' and the phone rep says by her records, my car has had all 'recall' work done.
But the 'serial data gateway module' is not called out explicitly.
My 23 HTC was delivered Oct 2022 so that explains why version is 2022. But when I check for updates for OTA, it says 'no new updates' (checked June 2024).
I've since disabled OTA updates and leave it to dealership when I'm in for service.

The Service Advisor told me the process takes about 3.5 hours to do - not sure why so long, but it is consistent with the idea that it's not an OTA operation.
If it were OTA, then there would no need to send the Recall notice I received in the USPS mail.

 

I recently had the update completed at my dealer. I was in and out of the dealer in a little less than one hour.

Not so...GM does not share data with LexisNexis any longer. So your insurance cannot get it.

I also requested that report after GM made this change and it did not show any driving details. They still collect the data but state it can only be disclosed to law enforcement.

General Motors said Friday it is severing ties with two data brokers following a lawsuit that connected the automaker to sharing driver data that resulted in higher auto insurance rates for that plaintiff.

OTA updates are not tied to your selection of GM online services. Unless you yanked the antenna, you'll still receive any OTAs that are pushed.

 

Texted with dealer late today, issue is resolved although not exactly sure what it was as of yet. Pick up car tomorrow. I'll see if any details are available.
