Range indicator said "Low" then Bolt immediately died.

Tue Apr 21, 2020 4:17 am

Right before new year, just under 36k miles, I was driving to a fast charger (4 miles away), as I pulled up to an intersection, my range meter went from 14 estimated miles, to LOW, and then immediately told me it was out of energy and to pull over. I've been to three different dealers (including the one i bought it from, 500 miles away), I've called GM's "customer support," and to this day, there really hasn't been any resolution.

I drove back across country, weeks prior to the incident, from Bakersfield, CA to Charlotte, NC, using only fast chargers. I'm wondering if the cells didn't balance, and that imbalance is what caused the occurrence. I use torque pro, and from the lowest SOC I've been to, I didn't see any glaring cell voltage differences (granted I'm no expert). I spoke to 2 GM EV engineers at fully charged live in February, who recommended a battery test at the dealer. I took it to the dealer i purchased it from in March (500 miles away), and they told me their tech looked it over thoroughly, that there were no problems, and I would have to pay for the battery test, if it yielded no results. Given GM's less than confidence inspiring performance to date, I declined, because the vehicle is driveable, and I now have documentation from two dealers stating the vehicle is operating as designed.

I plan on doing a final test, while with a generator for backup (GM's road side assistance is a cruel joke from my experience), and if the vehicle repeats the problem, or has significant variation in min range being achieved (as measured from right before it displays LOW), I plan to invoke Lemon Law, as I've given GM adequate opportunity to diagnose and repair. Lawsuits suck, but sometimes there's no other reasonable option. I hope the test will end with not running out of juice, and give validity to my cell balancing theory.

I just wanted to throw this on the forum, incase anyone has good insight, etc.

I sent you a private message pointing to other sources for help.

I don't know why, but I didn't receive it. If it's in your outbox and you can easily resend it, Is greatly appreciate it. Thank you!

Thanks again Tom. I'm fortunate to not have an issue nearly as bad (for now), as the person in the other forum. I've driven 20,000+ miles since the night it died (right before the new year), but I won't push it and go below 20 miles of range anymore. I'll test it at some point when I have access to a generator, unless it happens again before. The attitude of GM corporate and dealerships I've interacted with is truly disheartening, which means the Bolt and my Spark EV, are the last GM product(s) I will own, at least for probably an extended period of time.

It nearly happened again the other day. I was traveling, stopped for an hour, had 31 miles of range left. Picked out a charging station 12 miles away. Took back roads instead of the hwy which cut the distance, and was more efficient than I had been driving prior to the stop, and looked like I was going to end up there with 23 miles of range remaining.

I was slowing down at a traffic light a third of a mile away from the charger, and happened to look down at the dash... 16 miles of range remaining.... WTF (not, Wow That's Fantastic!). Still regening as I'm slowing down, and the figure falls to 15 miles of range remaining. Now at a stop, range goes to low and propulsion reduced. Think I might be forked, but soldier on. Fortunately make it to the charger without entering limp mode.

Hook up to the first charger, a new Electrify America Signet unit (the one right next to it is powered down, already broken...great), dash reads "Can not charge." It's raining of course, fortunately not torrential. I power the car to the on position and try again, charge initiates, but no power is being supplied (never seen this before), then it faults and ends the session. I begin mentally preparing myself for unpleasant options, being 200 miles from home.

There are two more chargers, so I move to them, leave the car on, plug in, and fortunately it charges flawlessly. I take several minutes to try to unwind and decompress. Forgot to mention, I had the sense to check Torque Pro for individual battery voltages upon arrival to station, and there were no significant deviations. Didn't have the sense to put a load on (heater perhaps) to see if that changed things. Maybe it's a software issue? I know GM forked around and changed at least a few things in the battery control module, as 2019's give a nonsense number for the battery capacity estimate.

I've been to 3 dealers on 4 different occasions for this issue, and feel like I'm out of good options to resolve the issue.
