I’m having the same symptoms, had it towed to the dealership but it started up there even after a GM roadside assistance person couldn’t jump it. Dealership said they found nothing wrong with it and sent us away. Now, 3 days later it’s completely dead again. Glad I ran across your video, ill be getting it towed back to them tomorrow and will share the info with them.

Exact same problem on my wife's 2022 Suburban. First time was 6 months ago. Local dealer replaced the battery. Second time, three months ago, the dealer kept the vehicle for three days and said "nothing is wrong." Third and fourth time happened over the past ten days. I'm bringing the vehicle into my local Chevy dealer on Friday, 10/27/23.

Show this video and how we tested. All get a data log of all the firmware uploaded into the truck and dates they were installed.

I did. I'm literally sitting at the service department of my local Chevy dealership right now. I printed out your video link as well as the GM article that you provided. Also, FYI, another came out earlier this month concerning Colorados. Same issue. I handed them all to my service advisor, who immediately told me that he was acutely aware of the issue. (He also noted that it's worse for Colorados because the dead battery somehow affects the ability to use the brakes.) For now, we're going to handle it by shutting off the OTA allowance in the Suburban. When I come in for an oil change or other service or maintenance, the dealership will do the download while that's occurring. I won't have to deal with dead batteries at home anymore. Thanks for your help. FYI, I have a colleague who drives a 2019 Subaru Outback with the same problem. (Lots of information online about it.) I'm sure he'd love to see you do a video on that.

Sooooo what would the problem be if several modules are on? And how would we see all the connectors unless we completely remove all panels and the actual dash?

@stealthg35infiniti94

@@AnthonyJ350 So let's say several modules are on. You go on All Data and get a power distribution circuit. See if modules are in the same branch of the circuit. Read the theory of operation and see how the system is supposed to operate. You may have an ECM, PCM, or other Modules not performing correctly. A bi directional scan tool can see the CAM Buss to see if the suspected problem module is not going to sleep. This type of Diagnosis is best left for Experienced Automotive Diag Techs. Even if you got lucky and found a HOT Module, the replacement one might have to be programmed to the vehicle. BTW, in another scenario, if you had a dirty/corroded connection, it would heat up higher than the surrounding area. The infared imaging Camera shows the Hot areas in amber, reddish color. Ivan @PHAD did a good comparison on some entry level units for the DIY.

This is nothing new. But they're not fully testing the software/ firmware when they develop it under all scenarios.

Since when was a car called a truck?

@AnthonyJ350

When the vehicle is a full size SUV on a later frame with a pickup truck front end, pickup truck front suspension, and pick up truck powertrain I guess.

Initial surge and taper is the ECU and other compute modules initializing. Should not draw more than 50mA in standby when there's no heavy computing. At 12V, that's only 120W for computing at 10A draw. Start pulling fuses looking for the draw. Could be something like heated seats on from bad module. You bought a MultiMeter from Snap On ? Aaahahahahahaaaa!!! Get a Fluke.
