Chevrolet Bolt Euv Ev Premier, 2019 ENCAR40060897

As a result of an investigation by GM and LG Chem into a fire accident that occurred in the United States, it was confirmed that there was a potential battery cell manufacturing defect in the high-voltage battery produced at LG Chem's Ochang plant in Korea. In this case, smoke or heat may be emitted from the high-voltage battery when charging the high-voltage battery at full charge or close to full charge, which may cause the high-voltage battery and other parts to melt or be damaged, creating a risk of fire.

1. Check the battery module using the high-voltage battery diagnostic procedure

2. If necessary, replace the battery module or battery pack

3. Hybrid powertrain control module 2 and body control module software update

1. Continue existing recall work currently in progress

1) Check battery module through high-voltage battery diagnostic procedure

2) Replace battery module or battery pack, if necessary

3) Perform hybrid powertrain control module 2 and body control module software update

​ (“Advanced onboard diagnostic software” update)

2. Change the maximum charging capacity of the vehicle to 90%

It was confirmed that two extremely unlikely manufacturing defects exist simultaneously in the same battery cell of a high-voltage battery. In this case, when the battery is fully charged or close to fully charged, the high-voltage battery with the manufacturing defect may generate smoke or heat, which may melt or damage the high-voltage battery and other parts, causing a fire. In response to the recall limiting the charging capacity to 80%, please visit your nearest Bolt electric vehicle service center and receive priority software update, and we ask you to read and follow the important instructions below before your visit.>

<※Important Information>

1. For safety reasons, please be sure to change the maximum charge capacity to 90% in the "Target Charge Level Option" through the charging option settings in the vehicle until this recall is addressed. (How to set the target charge level: https://youtu.be/u5_mBIQcPoQ)

2. Please charge the high-voltage battery as often as possible after driving the vehicle, and avoid allowing the remaining driving range of the high-voltage battery to fall below 70 miles (approximately 113 km).

3. To avoid emergencies, park the vehicle immediately after charging, and do not leave the vehicle while charging for a long time (e.g. overnight charging). Please.

<※Customer preparations when replacing high-voltage batteries>
1. To ensure rapid high-voltage battery replacement, do not perform high-voltage charging (within the plug) the day before arriving at the service center (within 24 hours). Please.
2. When arriving at the service center, the high-voltage battery must be in a state of charge (SOC) of less than 90%.
3. Recall for high-voltage battery will be carried out by reservation due to limited exchange locations, so please contact GM Korea Customer Center at 080-3000-5000 for the replacement location and date. Please consult.

Installation of improved diagnostic software and maximum charge limit of 80% [*For some vehicles 2022.01.24 / 2022.01.27 / 2022.05.03 / 2022.05.25 / 2022.06.27 / Battery replacement and improved diagnostic software update (recovering 100% maximum charge)] are possible from 2022.11.14. Please contact the manufacturer's customer service center for details. Please.]

** 2019 model year vehicles: After installing improved diagnostic software and limiting the maximum charge to 80% from 2021.12.03 → 2022.01.24 / 2022.01.27 / 2022.05.03 / 2022.05.25 Considering the improved high-voltage battery supply and demand schedule, etc., battery replacement and improved diagnostic software (100% maximum charge reduction) installation will be carried out sequentially [in the second half of 2022 (around July)]. style="color: rgb(255, 0, 0);">

** 2017-2018 model year vehicles: From 2021.12.22, improved diagnostic software will be installed and the maximum charge will be limited to 80% → 2022.06.27 / 2022.11.14 Battery replacement and improved diagnostic software (maximum charge 100% restored) will be installed sequentially in consideration of the improved high-voltage battery supply and demand schedule.

Recall due to the possibility that the insulation material under the carpet adjacent to the lower part of the B-pillar (pillar between the front and rear seats) may ignite due to the high temperature gas generated when the front seat belt pretensioner is activated. In this case, a fire may occur in the carpet adjacent to the lower part of the B-pillar when the seat belt pretensioner is activated. (*If smoke or fire occurs in the lower part of the B-pillar, please exit the vehicle urgently for the safety of the occupants. Required. City may require assistance from 119 Fire Department to prevent vehicle fire.)
