General Motors issued an advisory on April 5 to all owners of 2017 Chevrolet Bolt EV vehicles requesting they visit a dealership for a free software update due to potential battery cell failure.
Specifically, a small percentage of 2017 Bolt EVs may have a cell defect that can result in low cell voltage, according to GM.
To remedy the problem, dealers will perform the calibration software update which is intended to give customers additional warning if their battery is experiencing a cell voltage condition and begins to lose propulsion sooner than they expect.
If a customer does experience a loss of propulsion, GM advises that they go to a Chevrolet service center to have the battery checked. If it is determined that the battery is experiencing a low cell voltage condition, the battery will be replaced at no cost to the owner.
The company is not aware of any accidents or injuries associated with the battery cell issue. The automaker also noted that only some vehicles may experience the issue, however, it is asking all owners of 2017 Bolt EVs to participate.
GM told Automotive Fleet that this is not a safety recall but rather "a campaign about further improving the monitoring and warnings that already exist, and as such, was designated as a customer satisfaction campaign by GM safety experts and external safety monitors."
