I take Puppethead advise seriously and run. Away and let it burn bc my 2 lbs fire extinguisher in trunk is good to nock down a cigarette bud .
Fire extinguishers and water won't work for battery fires, that's the problem. Dousing with water (as much as 10 times more than a normal fire) is for keeping the surrounding temperature down to avoid spreading, not to put it out.

I believe in UK they developed a big fire resistant blanket to cover a car to exhaust oxygen to put fire down my fire extinguisher is a joke I my help someone on a road to put down fire on gas car or burning tire
 
Digging the web a bit more, there seems to be further information via Transportation Canada.

Issue:
On certain vehicles, a problem in the high-voltage system could cause a short circuit. If this happens, there could be a loss of power to the wheels and/or the high-voltage battery could overheat.
Note: This problem would cause a warning message to display on the instrument panel. This recall only affects the 3-door model. This recall replaces Transport Canada recall no. 2024-253.

Safety Risk:
A loss of power to the wheels could increase the risk of a crash. A battery that overheats can create a fire risk, even while the vehicle is parked and turned off.

Corrective Actions:
To reduce the safety risk, BMW advises that you should park your vehicle outdoors and away from other vehicles or structures until the recall repairs have been completed. BMW will notify owners by mail and advise you to take your vehicle to a dealership to update the vehicle software.

This is consistent with NHTSA's language:

Description of the Defect : Faults may occur in the high voltage battery or high voltage system, which could be caused by various reasons. These faults may result in a short circuit.

FMVSS 1 : NR
FMVSS 2 : NR

Description of the Safety Risk : This may lead to an overheating of the high voltage battery and, in rare cases, a thermal event, even when the vehicle is not in operation.

Description of Remedy Program : Potentially affected vehicles will receive a software update. This software includes a diagnostic function which detects a malfunction in the high voltage battery (in the high voltage system) and subsequently discharges the battery (below 30% State-of-Charge (SOC), high voltage battery emergency mode). Owners will be notified by First Class mail advising them of the recall and to schedule an appointment with an authorized MINI dealer to have the remedy performed for free. If this condition were to occur to a potentially affected vehicle prior to this recall, the remedy would be covered by the
MINI New Vehicle Limited Warranty program. Therefore, reimbursement for a pre-notification remedy re Part 573.13 and Part 577.11 is not necessary.

How you going to know which vehicle have an issue and 12000 owners driving a LEMON is like Russian rulete ?

You driving a lemon is like Russian rulete you don’t know what you drive if is yours or one of 128 units sold in USA and BMW can’t pin point which car is there a Lemon can heart you or burn your house to a ground
 
Had the update yesterday, quick and easy few hrs with a dealership courtesy car. We have about 40,000 miles on our 22 SE, haven't noticed any performance or range hits post update, just the nuisance Bimmercode drop outs.

Not worried about charging indoors, at least no more worried over charging and running all other garage electrical appliances. About two years ago we installed a couple X -Sense smoke detectors in the garage with wireless connectivity to two units near the sleeping areas.
 
I keep thinking about this recall and feel it's a half-solution. It seems this software update is designed to avert a thermal incident, but if I go to my car one morning and the battery is at 30% SoC, how does that make this a "fix"? Also, can it be recharged? Will it automatically recharge if plugged in after discharging to 30%, or is the battery locked from going higher? If this 30% safety margin is triggered, does that mean the battery needs to be repaired/replaced?

So many unanswered questions.

That’s a terrific idea. I think I will look into that. With two plugin vehicles, the thought of concern does cross my mind from time to time.

Including, is discharging to 30% safe enough?

However, with apparently only 2 events among ~100,000 (??) SEs sold worldwide, the risk doesn't seem especially high.

I’m seeing a dealer Friday 8 am I’m going to post what they did to @Rexsio a copy of fix and over the phone advisor mentioned KLE unit.
 
If more than 2 end up on fire, they might have to replace all of our batteries, just like Chevy did.
 
Hmmm... When I checked in for my annual state inspection on August 12, the young new hire at the counter said that there was a software update and battery thing due and asked if I wanted to have them also taken care of. Then I mentioned the last time I did a software update all my settings were lost and perhaps I should back them up or write them down prior. By that time, the senior guy returned and she asked him if settings would be reset. He quickly mentioned that the update hasn't been released yet and there are no parts for the battery. The last USB update reset some car's settings but not others, but this one won't affect the settings.

When I entered my VIN at the BMW site they say nothing is due. I was thinking this battery thing may be something different than the PSA/water leak thing. But I have heard nothing from the dealer or BMW. The Mini app is silent, but entering my VIN today says my mini is affected. I guess I was just a bit early for the official release but the dealer had a heads up. It may be more than software in some cases, if parts are required.
 
I'm in for my 2-year scheduled "maintenance" tomorrow at 7:20 am. Going to put the old headlamp switch module back in tonight just in case, but is there a chance they apply the update already? I don't have three or four hours to wait around.

Also haven't found anyone locally who might back up my CAFD files with Esys. One guy told me it wouldn't matter, because any backups wouldn't be compatible with a newer firmware. If anybody thinks he's FOS, and can do remote Esys tonight, let me know! Really just don't wanna lose Traffic Jam Assist. I can redo all the BimmerCode stuff myself.
 
Traffic Jam Assist?

I'm going to go in next week, and will just do Bimmercode stuff again. Bimmercode makes backups but you can't restore them if the software version changes.

It would be nice if you could record the steps you perform with Bimmercode and then tell Bimmercode to replay that sequence after a software update.
 
Wow, randomly checked the forum tonight and found our SE is affected. I remember checking the VIN a couple months back for something else on the forum related to the traction battery?

It's been sitting unattended out of state for months. Good thing we left it at 40% SoC based on the revised 2023+ manual. It always bothered me that the SE had no charge limit and a similar top buffer to other cars, with instructions to keep it plugged in at all times, when virtually all other EVs of this chemistry (including new BMWs) do not follow that scheme.
 
Traffic Jam Assist?
Yeah. Heh. It's a BMW feature that works quite well on cars with good ADAS using the multiple cameras and sensors that most BMWs sport now. With our single camera and the resulting wonky ACC, it's at best a very rudimentary version of autopilot. When conditions are perfect – well-painted lines on both edges of a lane or roadway is paramount – it works quite ok. I was stuck in crawling traffic last week in a part of town that maintains its roads, and I let go of the wheel and took my foot off the pedal, and kept my attention focused on potential lane-cutters and jaywalkers.
