If the high-voltage battery is fully charged or charged close to full, smoke or heat may be generated from the high-voltage battery, which could cause the high-voltage battery and other components to melt or be damaged, exposing them to the risk of fire, resulting in a recall due to this possibility.

<*We will notify you additionally when future software development and replacement parts are prepared, and we ask that you follow the important guidelines below until the final recall measures are carried out. >

[Important Notice] We have confirmed that two manufacturing defects, which are extremely unlikely to occur in the same battery cell of a high-voltage battery, can exist simultaneously, and this defective manufacturing condition may worsen when the battery is repeatedly/habitually charged to full or near-full charge after being significantly discharged, potentially exposing it to a risk of fire.
1. Please change the vehicle's maximum charging capacity to around 90% until a new recall measure is announced, and use the vehicle's charging option settings to change the 'Target Charge Level Option.'
If the customer is unable to change the settings on their own, they can visit a Chevrolet Bolt EV service center capable of performing recall work to have the setting changed.
2. After operating the vehicle, please make sure to charge the battery regularly, and try to avoid letting the remaining driving range of the battery drop below 70 miles (approximately 113 km).
3. To prevent any unforeseen situations, please park the vehicle outdoors immediately after charging, and if charging for an extended period (such as overnight), do not leave the vehicle unattended while it is charging.

<Temporary Corrective Action Method> Change the vehicle's maximum charging capacity to about 90%

<Final Corrective Action Method> Additional notification will be given once replacement parts for the final recall are prepared

There is a possibility that two extremely rare manufacturing defects may simultaneously exist even in high-voltage batteries produced through processes improved compared to conventional high-voltage batteries. In such cases, if the high-voltage battery with manufacturing defects is fully charged or charged close to full, smoke or heat may be generated, and as a result, the high-voltage battery and other components may melt or be damaged, potentially causing a fire, leading to a recall.

<*Before visiting, please read and follow the "Important Notice" below. Through the recall being carried out this time, it is possible to resolve customer inconveniences regarding items 2 and 3 of the "Important Notice".>

※Important Notice

1. Please make sure to change the maximum charging capacity to around 90% in the "Target Charge Level Option" setting within your vehicle for safety before receiving this recall action. (How to set the target charge level: https://youtu.be/u5_mBIQcPoQ)

2. After driving the vehicle, please try to charge the battery regularly and avoid letting the remaining driving range fall below 70 miles (approximately 113 km).

3. To prevent any unforeseen situations, please park the vehicle outdoors immediately after charging, and if you are charging for a long time (such as overnight charging), do not leave the vehicle unattended while it is charging.

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

(We will provide guidance through an additional customer notice when the final recall method is confirmed)

<*For safety, please visit the nearest Bolt Electric Vehicle Service Center and make sure to receive the software update.>

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. In this case, the recall is due to the possibility that 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 smoke or fire occurs in the lower part of the B-pillar, please exit the vehicle urgently for the safety of the occupants. If necessary, assistance from the 119 fire department may be required to prevent the spread of the vehicle fire.)

Attach insulation aluminum foil tape to the insulating material under the carpet 

It has been confirmed that two manufacturing defects, which are extremely unlikely to occur simultaneously in the same battery cell of the high-voltage battery, exist. If the high-voltage battery is fully charged or charged near full, a high-voltage battery with manufacturing defects may produce smoke or heat, which could cause the high-voltage battery and other components to melt or be damaged, leading to a risk of fire, resulting in a recall.
