I'm guessing these 3 are coolant? I wonder if I can investigate air pockets?

Yep, those look like it. Interesting that it has three of them. All are full, so that'* good . . . and bad because it'* not just that one is low or something. Maybe it'* a bad pump or valve or flux capacitor or something.

An update but still in progress.



The dealer is 95% sure my Chevy Bolt 2020 battery has a bad cell.

We’re also very sure (I’m never certain) it’* covered under the warranty as the car is far below both conditions of the warranty: “100,000 miles or 8 years”.



The dealer will get confirmation from GM’* engineers next week if the diagnosis is correct. Then it could take “3 days to 3 months” for the battery to arrive at the dealer.



Next week GM (I won't work directly with the dealer for this) will tell me if I can get reimbursed for a rental. There will be stipulations – a GM vehicle and – I think – if the dealer has the appropriate car available.

I’ve read in other forums that they’ll cover $45 per day. There are no rentals that cheap around here, but if they honor something like this, I’m satisfied with that.



It’* too bad: this is my first American car. I was trying to do the right thing, buying American. I hope it will take less than 3 months to remedy so that I can recommend Chevy to my friends.

Okay, that makes sense.

Sounds like you're definitely covered! . . . although I would be thinking the same thing, like maybe there'* some clause in the fine print that allows them to wiggle their way out of it, or something. If I had to give odds right now, I'd give 95% that you're covered.

That'd be cool, and all that sounds reasonable.

This is an interesting feat to attempt to achieve these days. Only about 20% of your Bolt is actually manufactured in the USA. It'* like 60%+ for the Toyota Tundra.

I wouldn't let this one issue dictate recommending an entire vehicle brand. They all have issues.

Your feedback is wise and strong.

LOL, thanks!

Updating my status so folks can learn. You can see it'* been a month and a half since I posted about it.

My 2020 Chevy Bolt wasn't charging well. The dealership (apparently the only place to go to get GM to pay for it) said I would have to wait up to 3 months for a replacement battery to be delivered to them.

Today they told me that GM decided it needed a software update instead. It charged and I drove it home.
I do work in software so I appreciate that when computers (this car is essentially a computer) needs "software patching", that might take time.
But I don't know any more than they told me so I'd love to hear anyone'* insight. Are there other Bolts that have needed a software update lately?

Part of my skepticism comes from the fact that in the beginning, the dealership asked me not to bug them. They would contact me the moment GM delivered the battery (back when that was the diagnosis) which might take months.
But I decided to bug them yesterday. And they told me that "GM sent the software update this morning". So that'* fishy.

Yeah, that'* fishy.

While presenting in the light of "that seems fishy that GM would do that to a dealership after three months, ask them what the current version is and what the new version is, and ask what changes have been made. Like all software, there should be release notes. This would appear to position you as an ally and not an enemy.

Worst case, they tell you nothing, update your car, and it is either fixed or not fixed, then you get the ball rolling. In the end, they have a lot of control of the situation. That'* the biggest struggle here.

I can't remember where you stand on warranty, but if these shenanigans put you within 180 days of running out of warranty, they need to extend it, and do it in writing. Easier to require of them since you're appearing to be their ally pointing out the shenanigans that GM is doing to them and you.

Is there anything to draw out of this concerning update version or errors or what these codes mean?

So this is after the software update, right?

It looks like they had a choice in September: Software update or replace battery pack.

Then as of this write-up, they decided to go with the software update. Makes sense to me based on this narrow view into the situation.

Big question: Does it charge correctly now?
