One new doc has appeared at https://www.nhtsa.gov/vehicle/2017/CHEVROLET/BOLT/4%20DR/FWD#recalls. It's now at 20 associated docs. Was stuck at 19 for a long time. I think it's https://static.nhtsa.gov/odi/rcl/2020/RCLRPT-20V701-7407.PDF submitted April 29, 2021.

It is pretty vague and mentions the software (we already know about that) and:
"GM and LG Chem’s investigation concluded that the known field incidents were likely caused by one or more rare, latent cell-level manufacturing defects in design level N2.1 batteries produced at LG Chem’s Ochang, Korea facility."

"Owner notifications of the final remedy are estimated to occur in two phases; the first on May 13, 2021 to address 2019 model year vehicles and the second on May 31, 2021 to address remaining vehicles. The final remedy will be executed under bulletin N202311731. Until the final remedy is available, an interim remedy is executed under bulletin N202311730."

From the top, the estimated percentage with defect is still 1%, just like in the Feb 2021 submission.

https://www.reddit.com/r/BoltEV/comments/n1sp1m/technical_details_of_n202311731_2019_recall/ supposedly has a high-level summary of the recall procedure.

Also, oddly, when I searched last night (e.g. https://www.cars.com/for-sale/searchresults.action/?mdId=36274172&mkId=20053&page=1&perPage=20&rd=99999&searchSource=GN_REFINEMENT&sort=price-lowest&stkTypId=28881&zc=00001) it seems like used Bolt prices have gone up.
 
Now realizing I'll have to eventually pony up $5 for foam to fix my Bolt's front seats. :cry:

What was the video? It's wiped out now.

Today, the # of associated docs jumped to 27. It was 20 last night.

Interestingly, from some of the new docs like https://static.nhtsa.gov/odi/rcl/2020/RCSB-20V701-5306.pdf, they so far have only released the final fix for 2019 model years.
"Vehicles involved in this recall had an interim repair made available under N202311730 on November 16, 2020. A final remedy has been developed for the 2019 model year. (The remedy for 2017-2018 model year vehicles is still under development, and will be released after validation.)

This is a phased launch."
So, that means they can't lift the stop sale on '17 and '18 Bolts yet.

As part of the jump to 27 documents, I only tonight noticed that https://static.nhtsa.gov/odi/rcl/2020/RCSB-20V701-5306.pdf has the actual instructions for the dealer tech, instead of the summary on reddit. The reddit entry also has been revised to point to the above PDF.
 
Bolt fire #7 a couple days ago. Elektrek has a little more detail after interviewing the 2019 Bolt owner.
The owner had the temp recall performed in March.
He started charging at '30-ish' miles and stopped at '160-ish' miles. It sounds like the EVSE was disconnected. A couple hours later the car went up in flames.

All I am willing to say say at this point is that the GM instructions to engage hilltop mode, or avoid charging above 90% SoC, or their March fix that I think prevented the consumer from reaching a high SoC in any case --- were likely proven ineffective. GM is now saying that it is not a high SoC that is the fire risk, it is a low SoC.

Whatever. Let's just agree that GM is clueless, but happy to declare 'problem solved' when it is not and put their car owners in danger. I came *this* close to buying a Bolt last month. I consider myself fortunate that the deal fell through since I am fairly certain that my wife would have rightfully demanded that I tow the car to the closest GM dealership and leave it there with a big sign that says "BEWARE. Unresolved Spontaneous Combustion Risk."

https://electrek.co/2021/05/07/exclusive-the-latest-chevy-bolt-fire-reveals-troubling-pattern-that-owners-should-be-aware-of/ came out just today and since I have a day job, I've not had time to read it in detail yet. Prior to this, there were almost no info and only plenty of speculation and questions re: the above incident. Sean (the author of the piece) is a Bolt enthusiast and an admin on at least one Bolt FB group I'm on.

There was no special "March fix". The temp "fix" to limit high SoC came out in Nov 2020 but drivers could've waited until any time to have it applied (or not). If in fact this Bolt caught on fire due to the same battery defects that this recall was for and that limiter fix was applied, then yes, I agree, the "fix" was ineffective.

It is possible there is another defect(s) which caused this fire or something that was unrelated to the Bolt itself.

Have a source for the bolded part?

Again, the final remedy (all 11 pages) for recalled '19 Bolts is at https://static.nhtsa.gov/odi/rcl/2020/RCSB-20V701-5306.pdf. It is n/a for '17 and '18 Bolts at the moment. https://static.nhtsa.gov/odi/rcl/2020/RCLRPT-20V701-7407.PDF says "GM and LG Chem’s investigation concluded that the known field incidents were likely caused by one or more rare, latent cell-level manufacturing defects in design level N2.1 batteries produced at LG Chem’s Ochang, Korea facility."

It is unclear why the '19 final remedy became available first. I have many guesses but who knows if we'll ever know why.

Wow, that wasn't reported on the evening news. Oh, it isn't a Tesla.

Sadly for this owner, they didn't follow GM's most important advice on this problem so far: don't park your Bolt inside a structure until this problem is resolved.

No kidding.

I'll guess less a conspiracy, and more a case of people not caring about the Bolt, so why read about its 'issues' ?

I'm not so clear that was GM's advice.

From https://static.nhtsa.gov/odi/rcl/2020/RMISC-20V701-4459.pdf and others, it seemed like the advice was along these lines:
All Model Years: If you are unable or uncomfortable enabling one of the above described charge-limiting features in your vehicle, you should park your vehicle outside as soon as your vehicle completes a full battery charge.
https://static.nhtsa.gov/odi/rcl/2020/RMISC-20V701-2689.pdf is an old version of the FAQ that says basically the same thing in Q8. Ditto for https://web.archive.org/web/20201127201550/https://my.chevrolet.com/how-to-support/safety/boltevrecall.
 
https://www.facebook.com/groups/chevroletevgroup/permalink/1402152823474955/ says "The future is all electric. The new 2022 Bolt EUV and redesigned Bolt EV have left the factory and are shipping to a Chevrolet dealership near you."

I also received a marketing email today w/the subject line "(my name was here), the All-New Bolt EUV and refreshed Bolt EV are in production".

OT:
Victoria Fire Department adds new electric vehicles called FireBolts to fleet

Hmmm....
 
As I posted at https://mynissanleaf.com/viewtopic.php?p=604955#p604955, the final remedy for the recall covering '17 and '18 Bolts came out on 5/26/21. So, that means the stop sale can be lifted on all recalled Bolts (all '17 and '18 + subset of '19) once the final remedies are applied.

https://my.chevrolet.com/how-to-support/safety/boltevrecall has been updated to reflect that and I've seen reports some '17 and '18 folks have gotten theirs done.
 
I hear rumors on another forum that the update also changes the DCFC curve for older Bolts. Instead of the staircase ramp-down, it is claimed that we will get the more gradual curve, which is probably a true Constant-Current -> Constant-Voltage profile.

I haven't heard anything from Chevy yet about the final fix. When I get it applied, I will be testing the DCFC curve for myself.
 
The procedure for covering all the recalled vehicles (all '17 and '18 + subset of '19) is up at https://static.nhtsa.gov/odi/rcl/2020/RCSB-20V701-3618.pdf. '17 and '18 final procedure didn't come out until a few days ago and as usual, there's a lag before appearing at NHTSA.

https://www.nhtsa.gov/vehicle/2017/CHEVROLET/BOLT/4%252520DR/FWD#recalls grew from 29 to 34 associated docs sometime today.

https://gm-techlink.com/?p=14834 explains the new DTC and diagnostics.
 
https://www.chevybolt.org/threads/my-recall-experience.38805/ is the 1st one I've personally heard of where it was identified they will need battery repair (e.g. modules or sections or entire pack swapped out) as a result of the dealer going thru the work for the battery fire recall.
 
There have been a few more and I or someone needs to start a list tracking either failures during the dealer diagnostics or afterward.

https://www.chevybolt.org/threads/no-start-after-second-recall.38925/page-2#post-616032 needed a new battery section.
https://www.chevybolt.org/threads/no-start-after-second-recall.38925/page-2#post-617450 is getting a whole new pack.
 
Year over year, sales of a redesigned Bolt EV and new Bolt compact SUV jumped 351% to 11,263 units, per GM press release today. That's starting to be some real numbers for a car model.

Thanks for that.

I found https://investor.gm.com/static-files/cc08e14b-29ae-4271-bffa-810b56ed0d83 from the bottom of https://investor.gm.com/news-releases/news-release-details/gm-second-quarter-sales-increase-40-percent with some numbers.

From looking at https://usa.nissannews.com/en-US/releases/release-10e81128ff45380ddab0a113f80cecd5-nissan-group-reports-second-quarter-2021-us-sales, in comparison, seems like US Bolt sales are over 2.5 times that of US Leaf sales for 2021 CYTD.
