I called the EV concierge today to see if I could find out where I am in line. I told him that I live in the north and am concerned about leaving my Bolt outside in cold/snow/ice. They answered very quickly--after pushing "1" he was right on! He could not tell me when I was "due" for the battery replacement, but he then double-checked the software and said it was available now, and if I had that installed, I could resume charging inside, and I could drain below 70 miles. The negative is that it reduces my charge max amount to 80%

To be honest, this is not a bit problem for me. I seldom have ever gone more than 150 miles or so on a charge. But I'm wondering if this is really the software that has been discussed before which reduces your charge, monitors the battery, and gradually (if it sees no problem) raises the maximum charge limit. I also wonder if upgrading the software moves me back in the battery replacement queue...Any thoughts? Anyone have any details from a GM service tech or something?

Another possibility for this software: Maybe it just changes the scale so that what used to be 90% is now called 80% and what used to be 70 miles is now called 0 miles?

Based on what we are seeing, the update will leave you with an actual 80% range. We have not seen ANY indication that it will change your spot in line for a battery, as this software will soon be available to all Bolt owners. This IS indeed the software we heard about, but it will not directly raise the charge rate. It will have to go back in to a dealer later for the rest of the range to be restored.

There is some more discussion ongoing in this thread.

I wonder if it is just adjusting the SoC levels, what happens if you run the battery down to zero? Do you get that extra 10-20% or whatever is left at the bottom?
I surely don't know, but you are losing 10% at the top (about 25 miles) and gaining 70 miles at the bottom (since that restriction has now been dropped)

Oh, you got an email direct from GM about the s/w? I did not get that yet, but I did call the dealership. The "generic" appointment people said there was no recall yet on my VIN (I don't think the s/w is considered a recall) but they will talk to the EV Specialist when he comes in on Monday.

GM is a big company with thousands of dealers and millions of customers. I can imagine it being very difficult; I'm willing to give them a break on this. I also love the car!

And after 2 previous software updates to limit the charge to 90% for safety's sake and then "the final fix" software update that restored things to full range if no problems were detected in the process, we are now all supposed to assume all is well with this new update to get us back to 80% range and parking in the garage and all that? I have a 2019 with the Korean built battery, so I am not exactly confident that all will be well with regards to overnight charging and parking in my garage, etc. If the software at least has diagnostics that we don't currently have to warn of impending problems, then I suppose it's worth making the appointment to have it done soon, but my "fire-Bolt" is still gonna be living on the street I think.

Another thought, with OnStar capabilities, you would think that GM could have provided over the air software updates, like other manufacturers have now. Dropping the car at the dealer for a day for software updates, isn't exactly convenient for most of us I'm sure. But at least it will be parked more than 50 feet away from my house for a day.

Unfortunately, Bolts, at least '17 to '21 AFAIK can only have a very limited set of modules that can be updated OTA (e.g. infotainment system). As for others, besides Tesla, yeah, but only on some newer vehicles.

I also have wondered this. I have a 2022 EUV, and considering that it also has a direct cellular connection I'm amazed they can't just update this over the air. Especially considering the emergence of surveillance capitalism the last few years I would think they would also be pulling tons of other real-time data from the cars.

The earlier "software update" would have irreversibly limited the charge to 90% (something I already was doing with HTR when charging at home). The overall risk of a fire was in the range of 0.000167 (0.0167%). I have always felt that to charge to 100% once or twice a year (and to run below 70 GoM miles) was an acceptable risk, especially if you 1) did not leave the EV plugged-in after fully charged and 2) began the trip right as charging was completed so as to not leave the EV at that SoC for more than 10-15 minutes. I opted to NOT have the "permanent" limitation placed on my EV. Now we are told that if your EV "passes" the final (third defect) diagnostic evaluation, you can "charge to full" and park in the garage until the battery is replaced. However, with the battery permanently limited to 80% SoC, I do not feel this is suitable compromise. I may voluntarily limit my home-charging to between 25% SoC and 80% SoC, but for that 1-2 times a year that a road trip means that I NEED that full-charge to get to the next EVSE, I shall not hesitate to do so. {Remember that my state has NO DC Level 2 EVSE of > 24 kW!!} 2017 Bolt EVs are at a fire risk which is lower than the overall risk, and therefore my battery replacement is pushed behind the 2019 Bolt EVs which are at greater risk. If COVID has taught us anything, it is that risk is relative and that some very low risk is acceptable to some while not to others. Meanwhile, my Ioniq 5 reservation is still in effect, and awaiting ordering capability within 5-6 more weeks.

I understand the risks on the 2019's and they should be first. My concern is clipping the top end of the range at 80% with the new software WITHOUT a firm time line for when new batteries will be available to restore my 2020 Bolt back to 259 miles of range. (If you read the email we all got, 30 days after the software is deployed for the 2019's it is available for other model years.) It's just too much "trust us." This is I believe the 4th piece of software---albeit not GM's "final fix"-- but still. Is my wait for a MY 2020 new battery 1 year, 2 years, what? GM needs to publish the actual rates in which they are building batteries. They should be able to forecast by when 2019's will be done, 2018's, 2017's, 2020's, etc. They need to tell us a schedule. And yes, I know some cars will never be completed given the low rates of people actually having recall work performed. But still, WHAT IS THE SCHEDULE GM??. Otherwise, by installing the new software am I accepting a range limitation and surrender the right to file a class action suit against GM? I bought my 2020 Bolt with the 259 advertised range. I traded my one pay prepaid 2018 lease in early and bought the 2020 Bolt so I could not only avoid the fires on the Korean made LG batteries but also to get the longer range of 259 miles? If I install this software, I have a car with a range of 207 miles---might be temporary---but there is no schedule for when the new battery will be available to restore the car to the range advertised. . What will GM's compensation be for us owners who have had to charge away from home charging? Will I be able to turn in to GM for cash reimbursement for all of the DCFC's I have had to do away from home since the "no more than 90% and no less than 70 miles" restriction? Clipping top 80% may be GM's risk management strategy---but, I want to know WHEN I'll be able to get my new battery.

I agree with you.When i purchased my 2021 Bolt i was told i could use it for 259 miles and that the battery problem was solved.Now i hear that the problem is not solved on 2021 model and that i will get a software update that will limit my range.I don't think the updated software for a 2021 will be soon.If i need full range for a road trip will i be able to use my car a 100% or will the new software prevent my from doing so?I also agree with you that we would be able to get compensation $$$ for the lost of range.When GM started to sell EUV they offered free type 2 charging to new customer.They should also think of using this to compensating existing users for the lost of range.

Ditto.

By now, I am sure the plant shutdowns to prioritize cells designated for replacements must be creating some certainty as the replacement timelines.

Will older (2017-18) models come next on the assumption age is a contributing factor? What other factors might influence the timing of replacements? Will the new SW increase my chances of getting a new pack? Or will it defer my replacement timeline because I have a "good enough for now" solution?

I am planning a long trip to the E. Coast in March. I will need as much range as I can get for some of the stretches along the routes I am anticipating taking. As it stands, right now I have access to 100% of the pack capacity, albeit requiring I go outside of GM "recommendations". If I trade that for 80% "restriction", I lose 20% of the capacity. Thus, I hesitate. With more information, I might consider proceeding with the recommended update if I know 100% SoC will be an option for my trip. Without more info, I am inclined to keep what I have and wait for the new pack.

Then, there is the consideration of alternatives. Buyback? Trade in for another EV that isn't hobbled by the mess? Or take the wife's 115K mile ICE?

GM could gain some goodwill by being more forthcoming with information. It doesn't need to be 100% accurate, just some general idea as to how this will unfurl. Each new piece of the puzzle seems to introduce as much new uncertainty as it brings relief.

I think the software is a prelude to battery replacement so that the tech's don't have to discharge your car to prepare for the replacement battery pack to be installed causing less time in the dealers shop. Just my opinion!!!!!!!!!!!!

Not so sure, I believe there are shipping regulations on batteries, at least air shipping that requires they be discharged to some amount. Maybe ground shipping also has regulations?
