Re: [EVDL] Chevy Bolt Battery recall fix with software?

Thanks !

If you, or anyone, ever has the opportunity to do the same kind of trip 
in 35F ambient temperature, that would also be a good data point.


I've read that the Bolt is mediocre, in terms of maintaining range in 
cold weather. But real world data is always better than the usual 
subjective "analysis."

It was about 250 miles of relatively level freeway (I680 east of San Jose, CA 
and US101 south of San Jose, CA) at 65mph using cruise control.  The 
temperature that day went up to 80F, so I imagine the average for the drive was 
in the mid seventies. I set the climate control to automatically keep the cabin 
temperature at 71 degrees.

 I never got the software recall done on my 2017 Bolt.  Instead I just used 
hilltop reserve mode. I had the battery replacement done last August.

 I don’t know what my range was before I had the replacement because I usually 
only drive less than 50 miles. After getting the replacement, I did take it for 
a 253 mile drive using 59.3 kWh.

 How often do you drive 200 miles that you noticed the range dropped from 260 
to 200 miles?

Re: [EVDL] Chevy Bolt Battery recall fix with software?

[Peter Eckhoff via EV]

We went through the same thing with our 2019 Bolt.  Like you, we ignored
the invite but did set the car to "Hilltop Reserve" as recommendedand
parked it outside (garage was full) which would have been set by the
dealer anyway.
A while later, they said they had the new pack and we brought it in for the
servicing.  Two days later, we picked it up.  No problems since.  New
Pack.  New Warranty.  What's not to like?  Oh and the car did not catch fire.

I think that they probably consider it more important for the cars to look 
macho and aggressive, like their ICEVs do.  Hate and rage are trendy now, 
don't you know.  Hence big, heavy wheels and tires, a tall stance, ludicrous 
ground clearance, a boxy shape, and mean-looking front end treatments, all 
of which fight the air the car's going through.

Re: [EVDL] Chevy Bolt Battery Recall

[Mike Chancey via EV]

I have been told no over air updates for Bolts except for the entertainment 
center. I had to take mine in to get the 80% patch put in by a tech at the 
dealer until it gets a new battery. As I understand it, several of the Bolt 
fires were cars at a low state of charge. The problem is really an assembly 
issue within the cells. I think the newer Leafs don't have an 80% charge option 
anymore.

Thanks Ed, Mike for the informative reply. 
I still don’t understand why GM doesn’t display on the screen and users manual 
(like my Tesla Y and Nissan Leaf) does to only charge to 80% most of the time 
for local trips. Seems like this would help their 100% when hot charging cell 
(rare) fires. 
I got a letter from Chevy saying that they were going to reduce the range to 
80% (presumably over the OnStar air network).  A month or so it appeared that I 
had less range on long trips but could be a placebo effect….  Anyway I’ll check 
the link you recommended on the battery replacement status.  Sounds like 
they’re replacing the whole battery pack and not just individual cells since 
they can’t determine the cell shorting problem without destroying it.

the air tweaks) contrary to Consumer Reports last month black eye on

Re: [EVDL] Chevy Bolt battery recall

[Mike Chancey via EV]

There is a Bolt recall tracker at: https://bolt.areyouscared.dev/ that allows 
users to add their VIN and help track overall progress. Of course, VINs not 
entered aren't being tracked. GM is not doing the recall in any order that 
anyone can comprehend. Some from every year have been completed, but there was 
a push in the last few months to finish all the unsold 2022s on dealer lots to 
make way for the new 2023s. That push seems to be pretty much completed, so now 
they are picking up the earlier ones. BTW, the tracker hasn't been up that 
long, and only allows non-completed recalls to be entered, so replacements 
completed before 7/20/22 aren't shown. The recall reports at the NHTSA show far 
more of the earlier Bolts completed than the tracker does.

My 2020 Bolt became eligible for a battery 11/21/22, but I am in the middle of 
a repurchase/trade deal, so I am not getting it replaced at this time.

Re: [EVDL] Chevy Bolt battery recall

[Ed Blackmond via EV]

The batteries are being replaced because of a manufacturing defect. From the 
public description I believe that upon swelling at full charge, an arc could 
occur internal to a battery cell and start a fire. The defect is apparently 
rare, but there is no way to determine if a cell has the defect without 
destroying it.

GM discovered the manufacturing process that caused the defect and made changes 
so newer cells do not contain the defect. However since there is no way to 
determine which cells made under the old process are bad, GM decided to replace 
all the battery packs made from cells using the old process. This includes your 
2020 car.

As for your range reduction, did you really used to drive 260 miles per charge 
and now can only drive 220 miles per charge?  Driving the car from full charge 
until the charge is completely depleted is the only way to determine the range.

If you are noticing that the range estimate displayed on the driver’s 
information screen previously presented 260 and now presents 220, this is 
probably more of indication of how you have been driving.  Did you have to 
software update that limits the charge to 80% installed?  This will also effect 
the range display.

The estimates are calculated using a bunch of ad-hoc heuristics. The best thing 
you can say about them is that they are inaccurate (except if it displays 0). 

Having said that, the estimate combined with the trend bars is quite useful. 
The trend bars indicate how much better/worse you are driving compared to the 
estimate. If you always drive in a manner that keeps the trend bar above the 
range estimate, you will always beat the estimate. I find this combination to 
be a very intuitive and effective interface.

I have a 2020 and Jim sigel (grants pass) and Airport Chevy (Medford) won’t 
give me the time of day until more 2017s etc are done. I feel your pain.

[EVDL] Chevy Bolt battery recall

[Mark Hanson via EV]

Hi folks
I bought a new Chevy Bolt August 2020 (now has about 40k miles) and a year ago 
got a letter from Shelor Chevy saying they were going to replace the battery, 
now just crickets (dealer doesn’t know anything) Does any Bolt folks know if 
they just replaced the 2017s and not the newer cars?  The range has dropped 
from 260 to about 220 in warm weather. I noticed that Chevy is the only one 
that doesn’t say to charge to 80% for local trips , probably why they’ve had 
some 100% charging fires (clueless owners charging hot to 100% daily). 
Have a renewable energy Christmas 
Mark
