Degradation of greater than 40% of capacity would trigger a replacement within warranty period, well that is what was stated when I bought the car. I haven't paid attention if that language has changed since then, I have a 2017.Hi Everyone,
I will be buying a Chevy Bolt in November. I currently drive a Nissan Leaf. Nissan has had major issues with batteries in their electric vehicle and the 2011 Leaf that I purchased in 2016, came with a brand new battery. The previous battery was severely degraded to qualify for warranty replacement at 37,000 miles and less than 5 years of ownership.
Now I know that the Bolt battery is a completely different technology and is actively cooled and heated. This is one of the main reasons for my pending purchase of a Bolt, and the increased range is great. Every Nissan owner knows that if their battery health gauge of 12 bars, falls below 9 bars during the warranty on the battery, their battery will be repaired/replaced under warranty.
I can't find anything similar on a Bolt battery and what exactly triggers a repair/replacement under warranty? I know the bolt battery is warrantied for 8 years and 100,000 miles. What I am looking for is to learn exactly what triggers a warranty repair or replacement? So far the dealership hasn't been able to answer this question and they are actively searching, but so far nothing definitive.
FYI, the dealership I am working with for a 2019 Bolt LT purchase provided the following information on a replacement of the battery outside of warranty
$16,250 is your net price plus tax
labor is estimated at 6 hours $145 per hour labor. 6x$145= $870 labor
I have asked if individual bad cells can be replaced on a Bolt battery without the full battery needed to be replaced. I am waiting on an answer.
Hopefully, it will be years and years before I need to do anything with a Bolt battery. My interest is knowing up front what triggers a repair/replacement under the current 8 year/100,000 mile warranty.
Any assistance with information would be greatly appreciated!
I think his question is: how do you tell if you've lost 40% of your capacity? On the Leaf there's an indication on the dash that tells you how far the battery has degraded, but there's no equivalent display on the Bolt.1) a bad cell or any other complete battery failure.
2) greater than a 40% loss of capacity.
That is precisely what I have been bitching about on here for almost two years. Many of you just yawn, or find it funny. I think it is absolutely crazy that the government doesn't require a readout of battery capacity prominently displayed on a display on all electric cars.I think his question is: how do you tell if you've lost 40% of your capacity?

If one can drive on average 4 mi/kWhr they should be able to go 240 miles in theory on a battery charge.I think his question is: how do you tell if you've lost 40% of your capacity?

It doesn't matter what you get for mi/kWh. It is just simple math when doing a full range test to determine the usable capacity. But will GM accept my word for it? Will pictures of the displays be enough proof?If one can drive on average 4 mi/kWhr they should be able to go 240 miles in theory on a battery charge.
Pretty sure the answer is "no". GM would make it judgement based on service diagnostics.It doesn't matter what you get for mi/kWh. It is just simple math when doing a full range test to determine the usable capacity. But will GM accept my word for it? Will pictures of the displays be enough proof?
Diagnostics which we will not be able to see, and even if we did they have made no statements about a number. So what is to prevent them from saying, at ten years, sorry that isn't the number we were thinking of. You lose.Pretty sure the answer is "no".

Where most Bolts are sold the battery warranty is 10/150. Haven't seen many complaints about range loss in Gen I Volts, a number of which have crossed the 100K barrier by now.
First, they picked 40% precisely because that was a number that would pretty much never happen.Diagnostics which we will not be able to see, and even if we did they have made no statements about a number.

I know that most folks on here will be on their third or fourth EV by then. But for those of us who are in this to the end, it really does matter.
This is not like being struck by lightning. This is a written warranty on a $36K product we bought. I just don't understand how people can be so generous to giant corporations selling us products that, in the US, are practically a necessity.First, they picked 40% precisely because that was a number that would pretty much never happen.
If it does happen, the battery will be in a serious decline and it’s likely that a month later it’ll be 45%, etc. So if they did say “that’s only 38%”, you’d just drive it a little more.
Perhaps (whoever measures it) it could somehow be 39.4% at 100,000 miles, but you might also be struck by lightning or win the lottery with a ticket you found lying on the ground. You could spend your whole life pondering unlikely what-ifs.
We're talking about probabilities. For the situation you're worrying about to occur, you need the following:This is not like being struck by lightning.
You signed on the dotted line. If you didn't like the warranty, you should have written to GM saying you wanted to buy a Bolt, but were not going to do so because the warranty was ill-specified. Now that you've accepted it, it's a bit late to complain.This is a written warranty on a $36K product we bought. I just don't understand how people can be so generous to giant corporations selling us products that, in the US, are practically a necessity.
Not really. GM has been pretty proactive in replacing battery packs for people with failing cells, and that makes me think that they actually do want to do right by their customers. Even if car gave you a measurement dial on the dash and a promise that they'd replace if the capacity dropped by only 25%, you could later find that the warranty made no claims about charge/discharge rate, and that the BMS was “protecting the battery from degradation” by reducing these rates, limiting your enjoyment/use of the car.Honestly, do you not find it ridiculous that they are telling us they are guaranteeing 60% of a number they will not specify?
First off. I am quite sure GM wants their EVs to succeed, as they know better than most that from here on out transportation is going electric. I suspect they would be shocked if more than a tiny number needed to use the battery warranty.But all the evidence points to the fact that most of the time there isn't bad faith, because it's clear to me that if they did want to screw you over, there are many many ways to do it.
The government often lags behind in those areas, which I think is okay. Essentially, if something actually becomes a problem for society as a whole, then the government should step in and legislate or regulate.First off.

My beef is really with government. It seems like, eight years ago, it would have been easy enough to write a line into EV regulations requiring a readout of battery capacity.
As for not buying a Bolt...It was, and still is the only EV we could/would buy here in Virginia.
GM has a hundred years of customer experience telling them for 99% of their customers, no news is good news. Yes, Bolt and BEV owners are definitely different. However, for most ICE owners, GM knows dials/readouts on the dash are like pacifiers to babies; makes the owner feel better but don't really do much, because most never look and fewer understand.That is precisely what I have been bitching about on here for almost two years. Many of you just yawn, or find it funny. I think it is absolutely crazy that the government doesn't require a readout of battery capacity prominently displayed on a display on all electric cars.
Battery capacity is usually more a straight line degradation than is ICE lifespan, but both have the potential for catastrophic failure at any time in ownership. Today's ICEs have the hardware/software capability to display developed horsepower. Just hold full throttle for five seconds and see how much of the rated horsepower remains. Why isn't that a government regulation?My beef is really with government.

Happens most below-zero mornings in the frozen northwest. Should guvmint also have written a line into EV regs requiring the buyer to sign he had been read a statement indicating the 238-mile range estimate was a best case scenario and for six months of the year, it's more like 140-160 at best?Pray you don't wake up one morning after recharging your Bolt with the GOM showing 140 miles capacity...
But 350 x 171 = 59.85 kWh, which is lower than some have seen on their center screen for total used.GM officially published that in the Bolt EV's EPA filing documents (60 kWh: 350 V nominal at 171 Ah)
For true; GM got it right. The Bolt looks conventional, drives conventional, has enough range.As I have said many times, It is as sensible an EV as will ever be sold here,
Well, there were decimals, as well. :laugh:But 350 x 171 = 59.85 kWh, which is lower than some have seen on their center screen for total used.
According to Wesley, the Korean government officially lists Bolt EV's battery as being 350V 174Ah, which makes more sense, as 350 x 174 = 60.9 kWh.
That hasn't been what I've seen so far. While Bolt EV sales have been overshadowed by Tesla Model 3 deliveries, it's important to keep in mind that the Bolt EV has been selling as well as any other BEV to date. So I definitely wouldn't say that there is a lack of interest.Mostly, I am talking about this because I am bored with the slow pace of EV acceptance in general, and the pitiful interest in the Bolt in particular. As I have said many times, It is as sensible an EV as will ever be sold here, and the total lack of interest by my fellow citizens shows how hopelessly screwed we are.
