That is unfortunate. Hate to hear they are having problems. People are getting
more and more afraid of these batteries because of design flaws causing fires.

GM warns some Bolt owners to park outdoors due to fire risk

...
The company said Wednesday that the request covers 2017 through 2019
Bolts that were part of a group that was recalled earlier due to fires
in the batteries.
The latest request comes after two Bolts that had gotten recall repairs
caught fire, one in Vermont and the other in New Jersey, GM spokesman
Kevin Kelly said.
...
In April, GM announced that it had developed diagnostic software to look
for anomalies in the batteries of 69,000 Bolts worldwide. If problems
are found, the company will replace faulty parts of the battery.
...
At first the company didn’t know what was causing the problem, but it
determined that batteries that caught fire were near a full charge. So
as a temporary fix, owners and dealers were told to make software
changes to limit charging to 90% of a battery’s capacity.
GM traced the fires to what it called a rare manufacturing defect in
battery modules. It can cause a short in a cell, which can trigger a
fire. Under the remedy, dealers were to install software designed to
warn owners of problems, and any defective cells were to be replaced.
...
Engineers determined the fires took place in Bolts with battery cells
made at an LG Chem factory in Ochang, South Korea, from May of 2016 to
May of 2019.
...
Once the final recall repairs are made, the Bolts’ full range will be
restored. Older Bolts can go about 238 miles (383 kilometers) per
charge.
