Heard from the service dept this AM. They said whatever is causing the battery drain does it very quickly (within a day). They still don't know yet and had a test device on it last night to see if anything happened and he said nothing showed up but they know something is still doing it. They said they will focus on the radio/software and see if something there doesn't completely 'shutdown' sometimes. I told them if they had to default everything to factory, then just reset it (accounts, etc) if it helps them find out what is going on.

Nothing from me is plugged into the ODB port. Truck is stock from the factory; I haven't added anything to it except red/white/blue CHEVROLET 'decals' on the tailgate.

As I hear more, I'll update but right now, nothing.

Oh man! At least they're still digging into it, that's promising.

I owned a 2019 RAM 1500 for 6 years, and it ate a battery a year until I figured out through a lot of reading the forums that the power running board module wouldn't fully shut down if you deployed them using the screen and then turned the truck off (handy for washing them, for instance). Once I stopped doing that when parked at work (they stuck out farther than the bodywork, preventing door dings), my truck stopped eating batteries.

I tell that story because maybe there's some combination of actions/settings that is causing one of your computer modules to not turn off with the truck.

Good luck!

I can verify pushing the fuses in cured a glitch. A buddy's '24 Z71 manual shift button had quit working. Yesterday I checked and all but 3 fuses were not fully seated. Many were about 50% seated. His manual shift is now back to working.

Well, there's your problem, supposed to be Red White and Blue... Slashes makes the battery confused...

Dood, that just made my day! Thanks for that laugh. I'll forward this to the dealer so maybe, just maybe, my truck will be 100% reliable now.

Called dealer. Service Advisor said they are still working on the programming and ran into a snag and are waiting for GM TAC but they are hoping to get all programming done this evening, take it for a test drive, then let it sit overnight with test equipment to see if something draws amps. If not, they will release it back to me tomorrow. Told him that they need to call it what it is: a lemon and start looking at getting this permanently resolved as I do not trust that truck any more.

Anyway, still waiting......

So there must be a Module(s) that are not "shutting down" properly
This becomes a big problem now that so much is networked....
So. if one thing hangs up.....It can hang everything on the network up
Which would easily kill a battery

I'm hoping they get it figured out. I'm sure this is costing the dealership an arm and a leg if GM doesn't reimburse them alot.

GM will reimburse them. The biggest issue is lazy/uneducated mechanics and service managers. There are plenty of ways to find these draws. It just comes down to time and training.

There's no fuse for that button alone. It's integrated in the electronic shifting system. All software/computer related and unfortunately a lot of the Colorado/Canyons are software glitchy.

When you do get it back, can you please let us know the production date. It seems trucks produced in certain timeframes have specific issues. Like 24's that were from May 24 to around Aug/Sep 24 had the flickering headlights. This happened to be the timeframe when the bad run of lights entered the production line. I'm betting if we looked at the issues based on truck production dates overall...we would see some trends. My theory is there were bad runs of parts and as a community if we asked for production dates and linked problems on trucks...we would get trends and be able to help others with those production dates as fixes were identified.

Or it's really late and I've got too many things happening if life ....which would mean this sounds like a crazy guy rambling. If so...ignore me.

Thanks

Trends in Manufacturing do make sense
The Parts SHOULD go out in order
But, sometimes Inventory does get shuffled

I know from my Manufacturing Days and my Distribution Days (current)

This is from the dealer this AM:

I will say I do believe that the vehicle is now fixed, we performed vehicle wide programming per General Motors to every single module on the vehicle that would pull battery voltage. General Motors thought is that the body control module was waking up at night and taking voltage and that's why the battery died, we have performed several parasitic draw tests after the update to find no draw

Sounds like they are going with a Module(s) is hanging a System... Which will in this case Wake up the BCM

Well, I THOUGHT they had this fixed last time. They said, on the 2nd tow, that it was the ABS system that was bad and killing the battery. And now this. So, I have no idea what to believe.

Well, totally understand and agree
1st time you had a Bad Battery (So, thought would of been Bad Battery.. Replace Battery.. All Good) That was not the Actual/Whole Problem
2nd Time Found the ABS System went Bad (Dealt with that.. All Good) That was not the Actual/Whole Problem
3rd Time Reprogramming all the Modules that would cause a drain ..... Might be it

Several Factors to why this happens
Techs only get paid so much time to diagnosis issues
An issue is found (but, not getting paid to confirm... so can't see if there is possibly more causing the issue)
Since Modern Vehicle are Basically Computers on Wheels... Once an issue can't be figured out, then you go to the Engineers to help sort it out (that is where the dealership is now)

What sucks is that GM doesn't care. They want to 'band-aid' it and hope it works for a while. In the meantime, I'm driving something that could strand me and my family because they are guessing. I'll probably be lawyering up on this as I'm tired of their excuses.

 

[Dankathy]

Another possibility is there were a number of failures and they worked through them. whether I'd give it another chance before starting the war, don't know. Confidence lost is seldom restored

 

[Xcanuk]

Honestly, their response sounds like a polite long version of "cannot replicate the problem"
On the other side of the fence, I can see their (the dealer) frustration down the line, unfortunately just too many modules and computers waking up and I'm sure they follow some type of flow chart for solutions. These new vehicles are way beyond my abilities.
When ever I get hit with a problem, computers or on the construction job, I go with the most common issue, address the fix, and find out its further down the line.
In the same difference, issues arise on plenty of projects and the others in my team go for fixes that just don't work, they call me in and its up and running in seconds, pisses them off, but I just have too much experience. One of the main reasons they don't want me to retire.

That being said, as I stated before, if I lose confidence in the product itself, its out the door

Hearing about these issues before I bought my 2024 in March last year, the first thing I did when I got home from the dealer (literally 40mi on the odo) were:
1. Push in all the fuses under the hood an in the passenger footwell....and they were all loose to one degree or another.
2. Turned off both of the automatic OTA (Over The Air) update settings. And until those settings got somehow turned ON again by the dealer, everything was fine with my truck. Unknown to me they turned them back on after a visit to the dealer...aaaannnd it bricked by truck (dead battery) about 2 weeks later.

As mentioned, loose fuses shouldn't cause a battery drain (unless it's arcing, in which case you've got MUCH bigger problems), but it might very well cause voltage fluctuations which would lead to glitchy screens/black screen of death etc.

The automatic OTA settings will DEFINITELY brick your truck if they're on.

Get a trickle charger SPECIFICALLY designed for these AGM batteries and use it religiously if your truck sits for even a week at a time.

So, maybe both your major problems with the truck are easily fixed by you without having the (incompetent) dealer having to look at it.

Best of luck!

GM Resolution called me a bit ago. I filed a BBB complaint and the lady was following up with it. She called me earlier and left me a voicemail (I was busy), and when I called back, she told me my case worker would call. About 5 minutes later, my case worker called and during the time she left me VM until she called me the 2nd time, she was reading the BBB complaint and all the repair orders. She went ahead and submitted it for a buy back. While on the phone, she said 'wait...I just got a notification that the buy back was approved' and told me the 2 options. I should get a settlement letter from BBB and go from there. I don't know what all this really entails, but they did speak to the dealership, and are trying to make this right.

I'll update as soon as I hear anything. FINALLY someone at GM listened.
