General Motors has officially responded to reports of isolated battery cell failure in 2017 Chevrolet Bolt EV models. In response to the possible issue, the automaker will roll out a software update for Bolt EV that dealerships will perform free of charge.
GM told InsideEVs that the recall is not a safety recall, but asked that all owners participate in the software update.
Some owners have reported battery cell failure that leaves the Bolt EV without drive power. After analyzing OnStar data, GM noted the issue seems isolated to very early production units of Bolt EV. The automaker will continue to comb through its data and notify owners who may be at risk for battery cell failure.
In the meantime, the software update will introduce “additional warnings if a battery cell low voltage condition occurs, which could cause the vehicle to reduce or lose propulsion.” Owners will see an indicator light if the battery is at risk of cell failure. The update will not fix bad battery cells.
Additionally, starting at the end of this month, Chevrolet and GM will begin pushing over-the-air software updates to the Bolt EV. It will make the Bolt EV the first vehicle from GM to make use of a vehicle’s internet connection for seamless updates without having to visit a dealership.
