Of course higher ambient temperatures could cause thermal runaway to happen minutes sooner. But to actually initiate a fire you are looking at hundreds of degrees above any earth temperatures, as shown by this study.
Yes, that was my point.

Thank you kindly.

If the battery is on a unstoppable runaway heating trajectory before it starts to significantly heat up, then any amount of cooling isn't going to help. Do we know that for sure at this point?
The battery cooling system in your Bolt has less than a gallon of antifreeze in it. That includes the external reservoir, pump, and hoses. Do you think that is enough coolant to have any effect on a fire?

My scenario is:
I live in a concrete high-rise with above-ground, enclosed, heated (for winter) parkade with those CO/exhaust detectors and giant exhaust fans and two sprinkler heads immediately above the car. One car next to me. I'm in a far corner with tight turns.
While doodling around an urban center, I'm charging up to about 75% and let it draw down to about 25% (really something between 20-25 and 70-75). Basically between the two bars on the GOM. Currently doing that on a free DCFC maybe once a week. Could be one more a week. Could be more than a week. I'll do more if I'm going somewhere of distance but not leave it parked inside ready. Occassionally I'll use a free L2 which I'll go back to when the DCFC is no longer free. No charging at home.

Do I need a whole lotta liability insurance? And would that be my condo insurance or car insurance?

Well, at least October is coming soon with cooler temps. Fortunately, my neighborhood is safe enough to park on the driveway.

And what would that few minutes buy you, if you didn't know it was going on?
I was imprecise in my post. The difference between inside and outside temperature is not important when the ignition temperature is so much higher. What matters is COOLING. Not degrees, but BTU/hour.

The battery cooling system in your Bolt has less than a gallon of antifreeze in it. That includes the external reservoir, pump, and hoses. Do you think that is enough coolant to have any effect on a fire?
Seems to work fine with engines that are designed with explosions in them. :) The amount of coolant isn't the point, the amount of COOLING is. The question is also not whether cooling can affect a fire (it can) but can it PREVENT a fire.

Thank you kindly.

If I'm risk management for GM, and thinking about the (admittedly rare) potential to burn down an apartment or condo full of people, I would have a fleet of 18 wheelers with checkbooks driving from one Bolt owner address to the next, picking up every car I could get my hands on. If a worst case scenario happens, a lawyer can easily prove GM knew the problem was there. That's going to be a settlement check to remember.

Hmmm. If your last statement were true, why would the lawyers even wait for the worst case scenario before going for the jugular? I mean, a dozen fires seem to be motivation enough, no?

Edit: I ask this question candidly and out of curiosity. I'm actually waiting for GM to buy back our 2021 as I type. I totally agree with your overall premise.

Per study: "Cells failed to be ignited at an ambient temperature of 162°C, but succeed to reach ignition at an ambient temperature of 169°C". 169 C is 336 F. Hardly an ambient temperature you will see, unless you park on a volcano. Your battery won't be getting that hot on it's own unless the chemical reaction has already started and if that started at 50 F or 120 F it won't matter.

That is not possible. I could park at the end of the parking lot at the food store with no other cars next to me. When I am done shopping there may be a car on each side. - great example is costco.
The same could be true at a gaming event.
My prediction is nothing will happen until a BOLT parked in a parking garage, goes up in flames, sets the whole multi-level building on fire and many deaths occur due to smoke inhalation.
Then, NHTSA will force GM to pull the BOLTs off the road aka buyback or trade.
Parking garage fires are covered in the U.S. building code under NFPA 88A. A fairly recent article in NFPA Journal ( NFPA Journal - Protecting Parking Garages, Mar Apr 2019 ) covers the problem and is mostly focused on the increased flammability of cars due to the increase in plastic in car construction. The totally burned our parking garage in the article was started by a Range Rover. Fires have always been a problem in parking garages and the plan is to be able to put them out quickly rather than eliminate car fires, which isn't realistic.

Anybody know how to reach this owner to find out more specifics? It is north of Atlanta.
The fire department give the address, so if you want to do some sort of lookup (property records, etc.) to find an owner's name and phone number or social media account, you can try that.

I currently have a broken passenger window ... It will take 7-10 days for the glass to get here...
I had a broken rear passenger window due to a break-in. The glass company said that they'd have to ship from the US and it would take over a week to arrive - but that wasn't acceptable to me because the Bolt is my daily driver. So I told the glass company to have it shipped overnight and I'd pay the extra cost. It was worth it for me.

No word on who made the battery? Went through the whole thread but didn’t see anything.
Who else would it be other than LG Chem?

I'm guessing you're wondering if it's the pack was made in Korea or the US, which I am too.

Lately it seems like insurance underwriters rule the world ... it's getting harder and harder to get away from their one-size-fits-all canned policies for all purposes, as the companies eat one another and conglomerate. And they're getting more and more restrictive (in parts of the PNW they have more or less imposed a de facto ban on wood heating, by jacking policy prices up astronomically for people with wood stoves).

So I'm wondering if sometime this year, as policies get renewed, apartment dwellers will find their landlords apologetically telling them, "Sorry but you can't park your Bolt in our parking bays any more because, you know, the fire risk... our insurance company warned us they won't cover us if we let you park there." And so on.

Sure hope GM gets this sorted out soon before it gets that ugly. I like my Bolt and I don't want them to buy it back, I want them to fix it (if it's even broken, which I guess no one will ever know).

this is what we all want to know, and whether he was following the Chevy advice. i'm sure one of the ev sites will reach out and find out.

Can you back that up with any sort of documentation? My understanding is that the Casino is NOT allowed to interfere with when or how slot machines pay out.
Watched a documentary of some sort. As long as they stick to the overall payout requirements, it's marketing to them.
