Chevrolet Bolt Ev Ev Premier 1G1F76E03K4133728

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

We have confirmed the simultaneous presence of two manufacturing defects, which are extremely unlikely to occur, in the same high-voltage battery cell. In such cases, if a high-voltage battery with manufacturing defects is charged to full capacity or near full capacity, smoke or heat may occur, potentially causing the high-voltage battery and other components to melt or be damaged, leading to a risk of fire. Due to this possibility, a recall <*to ensure safe vehicle use involves an improved diagnostic software update that strengthens high-voltage battery condition monitoring and a recall that limits the maximum charge of the high-voltage battery to 80%, which can be addressed by visiting a nearby Bolt Electric Vehicle Service Center as the first priority for the software We ask that you receive the update measures, and before your visit, please read and adhere to the important instructions below. <※Important Instructions> 1. Before receiving this recall service, for safety, please change the maximum charge capacity to 90% in the in-vehicle charging options under the 'Target Charge Level Option.' (How to set the target charge level: https://youtu.be/u5_mBIQcPoQ)

2. After driving the vehicle, please try to regularly charge the high-voltage battery, and avoid letting the remaining driving range of the high-voltage battery drop to 70 miles (about 113 km).

3. To prevent unexpected situations, please park the vehicle outdoors immediately after charging, and if charging for a long time (overnight charging, etc.), do not leave the vehicle in a charging state unattended.

<※ Customer Preparations for High-Voltage Battery Replacement>
1. To enable quick high-voltage battery replacement, do not perform high-voltage charging (charging without plugging in) within a day (24 hours) before bringing your vehicle to the service center.
2. When bringing your vehicle to the service center, the high-voltage battery should be at a charge state (SOC) of less than 90%.
3. High-voltage battery replacement recall will be conducted by appointment due to limited replacement locations, so please consult with the GM Korea Customer Center at 080-3000-5000 regarding the replacement location and date.

Installation of improved diagnostic software and 80% maximum charge limit [*For some vehicles, from 2022.01.24 / 2022.01.27 / 2022.05.03 / 2022.05.25 / 2022.06.27 / 2022.11.14, battery replacement and improved diagnostic software update will be carried out (restoring maximum charge to 100%)] is possible, so please contact the manufacturer’s customer center for detailed information. ]

** 2019 Model Vehicle: After installing the improved diagnostic software and implementing a maximum charge limit of 80% from 2021.12.03 → 2022.01.24 / 2022.01.27 / 2022.05.03 / 2022.05. 25 Considering the improved high-voltage battery supply schedule, battery replacement and installation of improved diagnostic software (restoring maximum charge to 100%) will be carried out sequentially [second half of 2022 (around July)]. ** 2017-2018 model vehicles: 2021.12. Installation of improved diagnostic software from the 22nd and limitation of maximum charge to 80% → Considering the improved high-voltage battery supply schedule on 2022.06.27 / 2022.11.14, sequential battery replacement and installation of improved diagnostic software (restoring maximum charge to 100%) will be carried out.

Recall due to the possibility that the insulation material under the carpet adjacent to the lower part of the B-pillar (column 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.)
