General Motors has issued another recall for over 50,000 examples of the Chevy Bolt EV electric hatchback over battery pack fires.
The automaker issued a recall in November 2020 for roughly 69,000 Chevy Bolt EV vehicles equipped with battery packs that were manufactured using faulty cells from supplier LG Chem. The recall saw GM dealers install new battery management software in affected vehicles, which was allegedly capable of detecting major battery faults before they happened. However the effectiveness of the new software was called into question after two more battery fires occurred in affected vehicles, with at least one of these fires occurring in a vehicle that had already been repaired under the initial recall campaign.
In a statement released Friday, the automaker said “experts from GM and LG have identified the simultaneous presence of two rare manufacturing defects in the same battery cell as the root cause of battery fires in certain Chevrolet Bolt EVs.” Vehicles involved in this second recall campaign will receive a new battery pack module. Just as before, Chevy Bolt EV models included in the recall campaign span the 2017-2019 model years.
The National Highway Traffic Safety Administration issued a directive to owners of the 69,000 vehicles involved in the initial recall campaign this week, cautioning them to park their vehicles outside due to the risk of vehicle fires. The safety watchdog has also instructed owners to not charge the vehicle past 90 percent and not let it dip below 70 miles of range to lower the risk of a battery fire. This is similar to GM’s interim fix for the battery pack fires that issued last year, which included a software update that limited to battery’s capacity to 90 percent.
