I wonder if this hasn't shown up quicker because many keep their cars on a battery tender.

I was in the dealer for another issue last week and they informed me of a recall/update that would take 3.5 hrs to load. I wonder if this this recall.

Just had it done on my 2024 Silverado. Service writer said sometimes it takes an hour, other times 4 or 5 hours. Go figure.

Just went to Ciocca on 9/9/2024 for an oil and DCT filter change.

Since the notification came out on 9/18/2024, I just missed it. Now I’m trying to decide if it’s worth taking the 1 3/4 hour drive back to Ciocca for the software update, or to bring it to my local Chevy dealer 10 minutes away.

I’m leaning towards the local guy because this should be an easy fix, right?

I just had the DCT filter service done this morning on my '23 Stingray. When I picked up the car, the service advisor mentioned they performed a GM recall programming of the serial data gateway module. Here's a clip of the invoice:


I drove it home from the dealer and didn't notice anything different.

Had mine done one day last week at the dealership. This has to do with the gateway remaining open/on and bricking the battery. Took about an hour or so. No issues thus far, don't really expect any.

It's interesting that this recall doesn't seem to apply to earlier year C8s but they also had the problem of OTA updates draining the battery. GM's solution for earlier cars seems to be to stop OTA updates for them.

Peterson Chevrolet did the update on my '23 2LT Coupe today. The car was in for a couple days on some other issues, so I wasn't worried about the time it took.

Hope the update fixes it. Sounds like a number of platforms have the need for it.

I have this recall on our 23 HTC, which will be addressed at the oil and filter change next week. I’ve not been overly concerned as the car stays on a trickle charger constantly.

I did have this issue on our 23 Canyon Denali. Woke up to the truck dead on the driveway after being parked 24 hours. I took it in, suggested it was the OTA situation and the dealer denied it. Within 24 hours of picking the truck up I received an email for a software update that would ‘streamline OTAs’.

i honestly have to wonder if they are watching their software platform, or their service tickets and sending the updates to vehicles they see present the issue….

Just an FYI, Recalls are always safety related. This does not apply. That's why it's not a recall.

What I don't understand is if an OTA update caused the problem, why can't they fix it OTA? I hate going to the stealership.

Yeah. It’s listed as a ‘customer satisfaction’. To the laymen, if you gotta take the car to the dealer it’s been recalled. The didn’t call the truck software a recall either, but it sure was a brick from their software issue and could have left me stranded given the issue was quite active. Semantics….

From what I understand, some updated happen in the background, some are requested to be installed by the user. These can get ‘stuck’ and the software isn’t smart enough to know that it has to stop attempting to install as thr battery is being drained beyond working capacity. That is hat happened to our truck. Dead in 24 hours. When I hooked up the charger it was at 3v and 4% charged. Took over 12 hours to bring it back to 100%. I’m assuming a simple battery monitor and programatic cutoff are what they’ve added to the software.

The dealership also refused to replace the battery. I pushed that drawing battery that low will damage it. They put it on a tester and it passed all tests for CCA etc so I was denied. They still blamed me and said it wasn’t the OTA issue.

Stealership is an understatement.

mine was 2 weeks ago and had the car an hour from check in to pick up. Not sure why dealers are quoting 3-4 hours other than to get more money from GM.

The time they quote you for the job has zero to do with how they're reimbursed from corporate... corp provides a set time for the operation and dealers are reimbursed based upon that value.

Great example of an invoice that spelled out the key steps in the DCT filter change procedure. It inspires confidence in this particular dealer. I think its rare to see one posted that has this much detail.
