In a statement General Motors Co said, it will replace all battery modules in some Chevrolet Bolt electric vehicles (EVs) following a recall earlier this month.
The replacement of the module could start as early as later this month. The development comes after the carmaker recalled its 2017-2019 model year Bolt battery-powered cars for the second time in less than a year. The recall came in the wake of two fire incidents, including one in a Bolt that had updated software.
On Monday, GM said it would replace lithium ion battery modules in the recalled vehicles with new ones rather than replace the entire battery pack.
“The battery pack case, wiring and the other pack components are not defective and do not need replacing,” said GM.
Earlier this month, GM had said the high-voltage lithium ion battery modules being recalled were produced at South Korea’s LG Chem Ltd’s Ochang facility in Korea. On July 23, along with LG it had identified the presence of two rare manufacturing defects in the same battery cell as the root cause of battery fires in certain Bolt EVs.
In a statement a spokesperson for LG Energy Solutions (LGES) said, LGES “will actively cooperate to ensure that the recall measures are carried out smoothly.”
In late July, GM said its second-quarter results included $800 million in costs associated with the recall of Bolt EVs.
GM asked owners to charge their vehicle after each use, where possible, in order to avoid depleting the battery below approximately 70 miles of remaining range, to reduce the risk of a fire. It also recommended that owners should park their vehicles outside immediately after charging and not leave them charging overnight.
Owner should also seek out the software update issued as part of the initial recall.
