Chevrolet Bolt Ev Ev Premier 1G1F76E09M4111610

Recall due to the possibility that when the high-voltage battery is fully charged or close to fully charged, smoke or heat may be generated from the high-voltage battery, which may cause the high-voltage battery and other parts to melt or be damaged, exposing them to a risk of fire.

<*We plan to provide additional notification when software development and replacement parts are ready in the future, and until final recall action is taken, we will keep the important information below. We ask you to comply.>

[Important Notice] We have confirmed that two extremely unlikely manufacturing defects co-exist in the same battery cell of a high-voltage battery, and these manufacturing defect conditions occur after the battery has been significantly discharged. Repeated/habitual charging to a fully or nearly fully charged state may worsen battery manufacturing defects, exposing the battery to a potential fire hazard.
1. Until a new recall action plan is released, please change the vehicle's maximum charging capacity to 90%, and change the 'Target Charge Level Option' through the charging option settings in the vehicle.
If the customer is unable to change the settings on their own, they can receive settings change by visiting a Chevrolet Bolt EV service center that can handle recalls.
2. Please recharge the battery as often as possible after driving the vehicle, and avoid allowing the remaining driving range of the battery to fall below 70 miles (approximately 113 km).
3. To prevent any emergency, park the vehicle outdoors immediately after charging. If charging for a long time (overnight charging, etc.), do not block the vehicle while it is charging.

Change the maximum charging capacity of the vehicle to 90% level

Additional notification will be made when replacement parts for the final recall are ready

Even in high-voltage batteries produced through an improved process compared to existing high-voltage batteries, two extremely unlikely manufacturing defects may exist at the same time. In this case, when the high-voltage battery is fully charged or close to fully charged, the high-voltage battery with the manufacturing defect may emit smoke or heat, which may cause the high-voltage battery and other parts to melt or be damaged, resulting in a fire.

<*Please read the “Important” below before your visit. We ask that you read and follow the “Guidelines”. Through this recall, we can resolve customer inconveniences regarding items 2 and 3 of the "Important Notices" below.>

※Important Instructions

1. Before receiving this recall, please be sure to change the maximum charging capacity to 90% in the "Target Charge Level Option" through the charging option settings in the vehiclefor safety. (How to set the target charging level: https://youtu.be/u5_mBIQcPoQ)

2. After leaving the vehicle in operation, please recharge the battery as often as possible and avoid allowing the remaining driving range of the battery to fall below 70 miles (approximately 113 km).

3. To prevent any emergency, park the vehicle outdoors immediately after charging. If charging for a long time (overnight charging, etc.), do not leave the vehicle unattended while charging.

Installation of improved diagnostic software and maximum charge limit of 80%

(We will inform you through additional customer notices when the final recall action method is confirmed)

<*For safety, Be sure to visit the nearest Bolt electric vehicle service center and install the software. Please receive parental date action.>

Due to the high temperature gas generated when the front seat belt pretensioner is activated, the insulation material under the carpet adjacent to the lower part of the B-pillar (pillar between the front and rear seats) may ignite, and in this case, a fire may occur in the carpet adjacent to the lower part of the B-pillar when the front seat belt pretensioner is activated. If necessary, assistance from the 119 fire department may be required to prevent the spread of the vehicle fire.)

Attach insulating aluminum foil tape to the insulation underneath the carpet

It was confirmed that two extremely unlikely manufacturing defects exist simultaneously in the same battery cell of a high-voltage battery. When a high-voltage battery is fully charged or close to fully charged, a high-voltage battery with a manufacturing defect may generate smoke or heat, which may cause the high-voltage battery and other parts to melt or be damaged, potentially causing a fire.
