Breaking News - Chevrolet has modified their Bolt EV Recall page to indicate that a final software fix will be available in April. They cite "state of the art software" and a return to 100% of capacity.


Read here for a deeper dive into this, especially considering Hyundai seems ready to replace their batteries.

Seems interesting that Hyundai had three times more fires than the Bolt. And seemed to have them pretty early too.

I'm gonna see how the folks at the Korean EV forum will react to this. This software-only update is the sort of thing that Hyundai did to Kona last year, especially the early detection of failure part. But at least one unfortunate Kona burst into flames even with that particular update done. I believe that was part of the reason why Hyundai had to consider doing the complete battery replacement.

I just received an email from GM saying that my car (VIN #...) needed to have the recall done and that the full charge would be limited to 90%. This is a little surprising considering I performed the recall update months ago. However, that update only limited my charge to 95%... and took away Hilltop. Am I missing something? Have there been two recall updates, or did the dealership perform it incorrectly? Is anyone else limited to 95% instead of 90%? Any insights would be appreciated. Really not looking forward to having to take the car in yet again...

How can I tell what the recent update limited my battery's capacity to?

I will not be accepting this newly announced software "fix". It does not fix the problem of dendrites growing through the separators. It might allow GM to try to single out which cars must have the battery replaced immediately, in order to prevent the cost of a massive battery replacement campaign. The problem would still lurk in every one of the recalled cars, and could become a major problem requiring a major repair at any time. That will ultimately mean that all early model Bolts will be "tainted" and suffer from reduced resale values. The "fix" is not a fix for consumers at all. It's a fix only for the bottom line at GM.

Only way I know of is by charging it fully.

But where is the number shown? I seem to recall only seeing a representational graph with 25%, 50%, 75% and 100% markers, as well as the high, mid and low guestimates on mileage.

UPDATE: Thanks, Doug. I opened the mychevrolet app, and can see that the battery attained 95% charge after the recent software update.

It does charge to something slightly over 90%. I think of the bars displayed as 'up to' the max for that range.
So, 19 of 20 bars in the state of charge display represents 90.1% up to 95.0% (I think that is right). If you have the mychevrolet application for your cell phone, you can look at the state of charge: Open App, pull down to refresh, slide 'vehicle status' to the left, You can see 'battery level'. In the end, if the car is as charged as it can get and 19 of 20 bars are lit, you should be set.
Unfortunately, Generous Motors dropped the ball in explaining what users would see in this case.

If you are bullish on the software fix not working... Always charge your battery to full. Leave it fully charged over the summer, without plugging in while at 100F + temperatures. After a week of sitting in the hot sun, jump on the freeway, drive 93mph and blast the AC.... and this last part is important, with THE WINDOWS DOWN. Rinse and repeat over the course of the summer. You should have a nice crispy Bolt in no time at all! Then simply let GM pick up the charred remains and then deliver a new car to your doorstep. Who's with me?

I'm very happy to hear that a fix may be ready in April. Today I got a third email saying to take it in for the 90% limit. Nope. I installed a wireless linked smoke detector in the garage out of an abundance of caution, but it's not like Bolts are burning up at an alarming rate, and nobody has been hurt in 300,000 vehicle-years. Another couple months will be fine. I'll be satisfied if the recall is resolved by new firmware that doesn't reduce range. I would only become concerned if a Bolt burns subsequent to getting the fix.

We are in a very fortunate situation with our Bolt. We are retired, and don't drive much, so normally charge to hilltop. On the few occasions we do a long drive, I charge to 100% just before we leave. Our garage is 150 feet from the house. After we are both vaccinated, and folks have reported back on how the "fix" works, we will consider it. Our main interest is till how quickly our battery will degrade.

The article title is very misleading. The software "as a fix" is only meant to detect potential fire risks. We will not see any limited capabilities as a result of the software, so the only assumption should be, if the software detects a fire risks in one of the modules, sections, or battery overall, those at-risk sections will be replaced.

Since the lemon laws in my state are terrible, I'm basically forced to accept GM's fix. That or sell the car.

Another thing to consider is even if GM said they would replace batteries, that isn't going to happen quickly. People like me that live in an EV desert will probably be at the end of the list. With Hyundai needing batteries, if GM also did the same, I'm sure I'd be in for a long wait. I'd probably be waiting for over a year.

I've got about 6.5 yrs left on my 8 yr battery warranty. If I own the car another 6.5 years I guess I'll have to make a decision whether I want to continue to own it once my battery is out of warranty. By that time we should know if GM's fix is a good one.

A Mach-E would be cool. So would a Model Y. I could tell myself that this whole battery issue is good reason to abandon the Bolt and get something else. But reality is for the way I drive and use a vehicle right now, the Bolt is the perfect car for me. It makes the most sense financially to keep driving the Bolt, and that is most likely what I'll do.

The only announced SW fix is the 90% that was announced months ago. The latest notices are re-iterating this. I have lost count, but have probably received at least 10 email or snail-mail notices from GM about the recall, the latest seem to add a little more information, but the temp "fix" has not changed. They also keep referring to using Hilltop Reserve\Target Charge Level as a mitigation step.

When the final solution is revealed, it may be palatable for most Bolt owners. We bought cars on the promise of 60kWh and are being limited to 90% now. If they can safely return to 100%, how are we worse off than before? I think many of us are speculating that GM is confident they can diagnose the problem with SW, identify cars at risk, and get them in for repairs before fires actually occur. That might also mean limiting charging when, and only when the defect is diagnosed.

If that final fix comes with extended warranty for this particular defect, we are safe, retain the capabilities that we originally purchased, and have added long term assurances.

For GM to incur excessive costs by replacing entire packs over what appears to be a relatively rare defect would be irresponsible to share owners. It might be a windfall to Bolt owners, but eventually those costs would need to be recovered, probably in the form of higher prices for several years.

It sounds like GM will be sourcing batteries from a different location than Hyundai, so they might not compete for resources. The batteries for the Bolt EV will be made in the U.S., whereas the batteries for the Kona Electric will be made in Korea.

If the purpose of the fix is to identify faulty batteries so that they can be replaced, then by not having it installed you eliminate any possibility of having your battery replaced. If that's your preference, more power to you.
I will most certainly have that "fix" applied in April, assuming I still have this Bolt at that time. I just would not accept that as a "final fix". The battery would still potentially have the same issue, which could become a problem at any time. The April fix only helps in terms of fire prevention.

What if the software counts the number of cycles to 100% with a finite limit. Or gives unlimited 100% charges but prevents charging to 100% if the battery temperature exceeds a predetermined threshold? Just throwing out some random thoughts on the subject.

Any idea if this upgrade will include the cold weather DCFC in it? Or does it over write it? I never got the upgrade, but if I am bringing it in anyway...
