Well, this is a first. I've had this 2017 Bolt EV for 2 years and have seen "Fully Charged" as 250 miles in the summer, and 180 miles in winter. I am just beginning to see these numbers fall-off to 86 miles on two recent "Fully Charged" cycles, with temperatures just above freezing. I will now schedule a service call to see what my dealer says. At this point it appears something is seriously amiss, and I plan to post on Chevy's attempt to understand/resolve this.

Yeah, please keep us informed at what you learn and if they start talking about battery replacement can you find out if they replace ALL of them, or just the bad pack that contains the bad cell(s) .... assuming it's a battery issue of course. I think there is a lot of misinformation about what is really getting replaced floating around.

If you have a bad battery (cell or cells), it'll probably trigger a recall for your car. If you check on the phone app or GM owner's site, you can see if you have a low cell recall.

Service Dept's initial response was unimpressive: "There IS a reduced range with cold temps." The earliest this issue can be diagnosed will be next week. When I know more I'll post. Note also: There have been no Bolt EV "recall" notices to me re: potential battery problems.

"Currently, there are no recalls or programs associated with your 2017 Chevrolet Bolt EV"
This vehicle, aside from the diminished range, remains perfectly drivable. But the earliest it can be "diagnosed" is early next week, after which another post will follow.

I suggest driving it until it stops, preferably in the middle of a multi-lane highway. I would then a call a lawyer and sue GM.

Yeah. I guess I would consult a lawyer first, about the best way to do this. ;)

Seriously though, this dealer's response is totally ridiculous. How do they know it is "perfectly driveable?" Did they look at battery capacity, or the 96 cell voltages? I have a $30 OBDII adapter, and a $5 app that can tell me these vital things in five minutes. They couldn't be bothered to do as much?

"There IS a reduced range with cold temps." Are they that stupid, or just being smart a$$ed? A total range of 142 miles on a 100% charge is grounds for a warranty replacement, but 86 miles or 36% is "perfectly drivable!" GM has a huge problem with their dealer network...and the rest of the old-line OEMs are no better.

I don't think anyone would dispute that something is wrong. And probably a warrantied issue. No one here, that should be allowed to log in, should be surprised at the stupidity that exists in every profession ...... and I'm going to throw this out there; especially car salespeople. Some people, and some are here, have no clue how stupid they are and are in full denial. 100% full denial. The car is broke. Things break. What has happened to the OP could easily happen to all of us. Our cars were made in Michigan. Have you been to Michigan? The U.P. ??? I have, and it's a miracle our failure rate is as low as it is.

Are you still getting a reasonable miles per kilowatt hour number? In the dead of winter I might see 2.5 m/kwh, during mild days in May or September close to 5.0. You'd have to consume power at a rate of less than 1.5 m/kwh to get only 86 miles on a "full" charge. I suppose if you sat idle for extended periods of time with the heat running it could happen. Or drove at 90mph all the time. If neither scenario applies, then your dealer has some explaining to do.

So would you drive this car down a busy highway at the assurance of this dealership that it is perfectly driveable? Either the battery is faulty, or the car is miscalculating SOC, range, or both. Either way I would be very hesitant to drive it.

I would experiment a bit. I don't think I'd put it on the freeway, but if I did I would stay in the right lane for sure .... might even be with one of those I D 10 T's who go below the posted limit on the freeway. But yes, I would drive it conservatively. I am not lawsuit happy like someone I won't mention. But I would take city streets and take it home. That's what I would do. Other's might escalate with management, call GM, call their local news affiliate and get a loaner and leave it there. But yes, I would drive it carefully, not race with it, not go to the #1 lane on the freeway and be somewhat responsible in my driving. I think both solutions are fine. The problem here is that this highlights the hidden secrets of dealership service that no one will talk about or acknowledge, here's some of the highlights:
1) Some of the techs are horrible.
2) Most of the service writers are horrible.
3) Dealerships want to see you something new and shiny and they lie. After you bought your car, they really don't care about you like you wish they did.
4) Sometimes the dealership as a whole, all the way into the rank and file have lied so much they actually believe their lies as truth.
5) Dealerships that say they have an EV tech, just might be .....dishonest.
6) Even GM doesn't know who's got an EV tech and who doesn't because one thing I know with 100% fact/certainty .... when tech leaves, dealerships take their time taking critical techs off their roster as far as GM is concerned.
7) Some service writers just make poor decisions. I make a few now and then ... daily it seems.
8) People need to get their heads out of their buttocks and realize things go south, it happens, try to not be a jerk.

If you reset the trip odometer... what are you seeing as far as mi/kWh?

If you're still seeing between 2.5-4mi/kWh then you have a serious battery capacity issue.

The simplest test.

I know I forgot to plug my car in one night, and did a 15+ minute pre-conditioning the next cold morning and my efficiency bar for my first 5 miles or so was below 2 mi/kwh.

GJETSON: THIS is the type of useful feedback I was hoping for on a forum such as this. The Service Dept's initial pathetic response not withstanding, current mileage range numbers do not bode especially well for this particular Bolt EV. At 40 degrees, this morning the vehicle's "Fully Charged" milage was down to 66 miles, which jumped all the way up to 70 after its electronics were fully energized. Another reply in this forum wondered about this Bolt EV's energy efficiency number. The average I usually see is around 4 mi/kWh, but today the average for a 24 mile drive was 3.6. My plan, if the entire battery pack doesn't self-destruct before I drop the vehicle off on Monday for their Tuesday "diagnosis," is to use the Bolt EV, sparingly while watching its energy numbers much closer than I ever needed to. As long as it shows a at least a 30 mile range it ought to easily make the trip to the dealership. Any range less than that and the dealer will need to decide how they want to transport it. The larger moment of truth arrives if the dealer claims this is just "normal" winter-related battery degradation. And given the vast amount of experience represented by this forum, do any among you seriously doubt that remains a possibility?

Thank you for THAT excellent recommendation! The reset efficiency is still a quite reasonable 3.9 mi/kWh, while this Bolt EV's "Fully Charged" range remains an abysmal 69 miles, down from the scary 86 that launched this thread. I wish the dealership could have made time for the "diagnose" element of this exercise inside of a week, but it is what it is. To be honest, for the first time as if I've run into the EV v ICE aspect of automobile sales at a large dealership. I don't think, as an EV driver, I'm somehow expecting better treatment than an ICE driver. I'm just surprised to feel I may be getting worse...

I drive my car in sub zero weather. I find with using the amenities that we paid for, I get between 2.5 mi/kWh and 2.8 when the temperature is close to or below freezing. I also drive half my commute on the Interstate and the other half on county highways. I have a comfortable range in the Bolt under these conditions around 150 miles. I see numbers all over the place with the GOM, never anywhere near your numbers, usually it is overly optimistic and close to 200 when I know 150 is the most I could get out of it. In the summer, I have frequently driven 240 miles with comfortable range to spare. The GOM always, in the summer tells me I am good for over 300 miles ..... also optimistic. YOUR car is broken. If you are comfortable driving it, enjoy it. It's under warranty and beyond adding stress to your life or stranding you on the road your plan of action is the same one I would use. I would drive it up as needed within the limitations it has presented itself. Since the GOM always lies, ALWAYS, it's pretty hard to know what your range really is. But the GOM should not be that far off.

Thank you for taking the time to weigh in. For the record, I've been loving this Bolt EV since Day One and sharing my positive experiences with anyone who will listen. This vehicle has ALWAYS performed exactly as advertised. The dealership, not so much. To have my relationship with the Bolt EV/dealership feel like it is going South, and fast, kind of rattles me. Best case scenario: the Bolt EV goes in, the techs diagnose what is a seriously-failed battery/charging issue, the dealership treats me like someone whose continued business they care about and makes the proper repair under the Bolt EV's warrantee. But so far the "gatekeeper" between me and the service techs has coming off as someone who needs to consider an attitude adjustment or other career options, and the entire situation is seriously harshing my EV mellow.

@legaldesign There's no consumer loyalty anymore, for those that are loyal they are in hospice, or headed there shortly. Equally, those selling products have transformed into a commodity price driven, no service, on to the next customer, last customer is not my next customer mentality. Retail has tried to push service again, and I see it at Best Buy and even Costco ..... I see people look at a price, for a product they are holding .... but they have their smartphone in their other hand and they are looking for the barcode so they can scan it into the Amazon App to price compare. And rightfully so, people want it for the lowest price and don't see any other picture, right or wrong. One of my best friends, for almost 30 years owns a chain of dealerships all with different flags. I visit him frequently, and the rotation of staff, including service techs is mind boggling. The way that industry treats their employee's is mind boggling. The service tech cares about what he can put on his time card for billable time. He cares about finding something 'else' wrong to fix and relaying that to the gatekeeper. The gatekeeper who gets a piece of the pie wants to sell you something or fix something in addition to what you came in for. That's the game. Warranty repair is not the game. That's not where the money is for them and that's why it's a double whammy for us. In my opinion, you're doing it all right, and coincidentally the way I would do it. There is of course more than one right answer here.
