GM Serial Data Gateway Module and Radio N242435631 Service bulletin - 24 Yukon

TrueAt1stLight · Jul 26, 2024

I had my Yukon XL AT4 (6.2) in for an oil change yesterday and they wanted to do this software update which they said was released on 7/23/24. Based on the horror stories I’ve read on here about these types of updates bricking a perfectly-functioning vehicle, I declined. Any idea what this one’s all about?

@WalleyeMikeIII may know something about it

Not sure on this one…but if they say you need it, I’d let them do it. I searched it but can’t find anything on it…

I’m not finding anything either on that N24 #… the bricked rigs have always been OTA updates that fail and drain the battery. If they install it at the dealer I wouldn’t worry about it.

Thanks all!

OMG....this is like me but I did allow them to try to update the radio. Now it won't work and the whole info center will not work. It has been at GM Cavender in San Antonio for 6 days now with no resolution. My Tahoe keep sitting outside on the back lot and has not moved since a day after I took it in. They are still waiting on GM to get with them for a resolution. Can anyone help on this??? I was able to get a rental car but it's a Nissan Kicks. Can tow my camper with that. Oh!!

Sounds like your dealer is not very familiar w/ the update process...I have had my radio updated probably 4 or 5 times and never an issue.

I just had my 23 Tahoe in today and got this update. It was at Y171.4.2, and now it's at Y172.6.1. Just got it back, and no issues yet. Fingers crossed.

I just had this Data Gateway Module recall/update done on my 2024 Tahoe. Just under 6k miles.
Took way longer than expected a couple hours for the over the air update and computer sync. Dealer told me approximately 1.5 hours when I dropped it off after getting recall notice.

So far everything seems fine but I did have to sign back in to some apps like Google. I do notice more light activity from truck than before the update when I get close with key fob.

Trailering boat to go offshore fishing tomorrow and I will get a better idea if anything is different after that.
