General Motors announced that it will recall some of its Chevrolet Bolt electric vehicles. The affected ones are those that were fitted with batteries made at LG Energy Solution Ltd.’s manufacturing plant in South Korea.

The affected GM Bolt model

As per Yonhap News Agency, the battery software must be amended to reduce fire risks. Based on the report, General Motors will recall Bolt EVs with model years from 2017 to 2019. A total of 69,000 units are affected.

The batteries installed in the Chevy Bolt EVs were said to have been manufactured in Ochang, located in the south of Seoul. The automaker said that it has sold 9,500 units of its Bolt electric vehicles in South Korea.

To address the said issue on the Bolt electric vehicle model, the battery software will be updated. GM said that authorized dealers will install "advanced onboard diagnostic software" on the cars to find potential issues related to battery module performance. The company will do this step to prevent any problem that may arise.

“As part of the service procedure, dealers will utilize GM-developed diagnostic tools to identify potential battery anomalies and replace battery module assemblies as necessary,” Chevrolet, a division of GM, said in a statement. “The remedy will also include the installation of advanced onboard diagnostic software into these vehicles that, among other things, has the ability to detect potential issues related to changes in battery module performance before problems can develop.”

Schedule of the repair for eligible units

General Motors voluntarily recalled the Chevy Bolt EVs in November for fire risks when the batteries are fully charged. This flaw made the owners to charge their cars only up to 90% to temporarily solve the issue. When the battery software update is done, it was said that drivers can now charge to 100% again.

Finally, Reuters reported that GM Korea will immediately carry out the recalls once the software needed for the process and other parts are ready. The company said it will start the repairs by the end of May and all affected units should be brought to designated dealers and repair centers.
