I got a letter from Chevrolet saying that an "updated" ADS package was now available to "address items that some Bolt EV customers have experienced after replacing the vehicle's high voltage battery". What "items" have people been having? I'm curious because I've experienced no problems. My Bolt is a 2019. Thanks to all who reply.

I didn't get the letter, but I'm curious if my Bolt needs something like this.
I don't have any 'problems'.
I do see a little weirdness at start up maybe half the time.
At button push the driver's display will show a 'spacey' "Waiting to Initialize" display for a few seconds and then start as usual.
Most of the time it just starts normally.
Has anyone talked about this behavior?

Had the waiting to initialize prior to getting conditions not correct for shift.
There was a software update that solved both problems...there is a thread on it here.
Not sure if this update is yet another one?

Isn't the unable to charge condition for 2019 models addressed in this latest update as well?

I just got this letter too. Any information from others would be very helpful - thanks.

And I found the relevant webpage on the Chevy site:
Most notably, "the new ADS will address customer complaints of difficulty connecting the vehicle to a charger or charging station (2019 model year only). It will also reduce false diagnostic activation in certain vehicles under certain driving conditions and help prevent diagnostic data loss compared to the previous software version." The update is only for 2017-2019 model years.
Anyone have further info? Are there any downsides, for anyone who's received the update already?
Thanks!
When you open the driver's door the car assumes that you are about to start it, and it goes through a kind of "boot up" initialization to prepare for that. But if you sit down, close the door, and don't start, then after a short period (15 seconds? 30? a minute?) the car goes back to sleep again. If you then start the car, you'll see the rotating sphere and the "Waiting to Initialize" message. Whatever it's doing during those few seconds are usually hidden between the time you grab the door and the time you sit down and hit the "Start" button.
Not to change the subject, but that rotating globe for directly adjacent multiple startups was one of the signs of the failure of my six-month old factory 12V battery. The battery passed a dealer "load test", but Chevy told them to replace the 12V battery anyway. No trouble since. BTW, on hot days, I now try to open the hood during a summer DCFC on the highway. It gets really hot in there, and that's in Mid-Atlantic states.
Thanks for the info!
I'll try repeating this process to see if it is consistent with both scenarios.
Are you saying ALL Bolts do this?
Yeah, I can imagine that part of the initialization routine would be to close the battery contactors, which could draw enough power from a bum battery to drop the voltage to the point where the computer resets, which lets the contactors open again, which would let the battery voltage bounce back up, whereupon the whole thing is repeated.
That would be my assumption until I heard evidence to the contrary.
I received it last week. I was expecting an earlier update but apparently this one is an improvement.
I have had some quirky things happen since my battery swap in February. I'm hoping this may fix whatever it is. Nothing seems to repeat. Just random failures.
Most issues have had to do with features of steering wheel mounted functions. For examples, Cruise Control will not set. Or, LKA will not turn on. Or, Auto Dimming turns on without pressing the button.
Last week, the 12V battery mysteriously died. I charged it and ran a simple load test and the battery seemed fine. I took it to the dealer and all they could find were codes set that were consistent with a dead battery. They could not find anything wrong. Did the headlights mysteriously turn themselves on? Now it's been about a week later and all is still good.
I'm thinking it's some random glitch and I'm hoping the update fixes it. I did start to carry a booster battery along with my 10mm wrench.😂
I had it done this morning. It is only for 2019 that have had the battery replaced. It (hopefully) fixes the charge port lock issue and (I think) the propulsion power reduced scenario that some people say can happen if the brake and accelerator are pressed at the same time, or if the car is rocked with the accelerator when on a hill or similar.
I'm going off memory on the propulsion power reduced thing. Someone correct me if I'm wrong.

I just got a letter about another software update.
"As part of GM's commitment to continuous improvement, we are making available an update an updated Advanced Diagnostics Software (ADS) package to address items that some bolt EV customers have experienced after replacing the vehicle's high voltage battery. This update will further refine your 2019 model year Chevrolet Bolt EV vehicles diagnostic performance, and will address potential charger connection issues some customers have experienced."
SPS is currently broken so I can't look up specifics on what's getting updated, but it sounds like we'll need to haul our 2019 Bolt EV's back to the dealership for another software update.

AFAIK, there are no "new" recalls since the Aug 17 as noted by Voldar above that fixes the P0BBD battery false alarm / 30% charge limit / propulsion power reduced problem, and a 2019 charger connection problem. GM is just now getting around to mailing notices about it. There are 2 flavors of that one, based on model year, but they are both under the same # [I think], and are functionally similar or identical. If anyone has a recall notice that references anything newer than Aug 17 and with a different recall #, I'd love to see it.
You can find recalls in the MyChevy App if you look really really hard, under Vehicle Overview, which is many many layers deep under your account info. You'd hope it'd show up under vehicle status but remember this is GM, and you should have no expectations. It will show up at https://www.chevrolet.com/ownercenter/recalls . This is not a safety recall and thus won't show up at the Recalls | NHTSA web site.

My position exactly.
As long as you can limp to the dealer with 30% SOC, that approach works. From what I have heard around here, the odds of this happening are not small. I'd guess that eventually many/most will throw this code without this patch. I will have it done when my local dealer regains the ability to do it. They had it but lost it. Maybe lost an EV tech?
As long as you're OK with having to take the car in for the update when it wants to rather than when you want to.
The impact of the "P0BBD" problem that this software fixes is more severe than the "cannot insert charge cord" issue (which is easily mitigated at home with a screwdriver blade or a 10mm wrench). If it were me, I'd get the software update at my convenience rather than risk the serious hassle of a forced trip to the dealer at a time not of my own choosing.
