General Motors Co says it is recalling 68,677 electric cars worldwide that pose a fire risk after five reported fires and two minor injuries.
The Detroit car maker said it will recall 2017-2019 model-year Chevrolet Bolt EVs with high voltage batteries produced at LG Chem's Ochang, South Korea facility.
The US National Highway Traffic Safety Administration (NHTSA) last month opened a preliminary investigation into the Bolt EVs after reports of three Bolts catching fire under the rear seat while parked and unattended.
GM said the vehicles pose a risk of fire when charged to full or nearly full capacity.
GM said it has developed software that will limit vehicle charging to 90 per cent of full capacity to mitigate the risk while GM works to determine the appropriate final repair.
Smoke inhalation injuries were reported in a March 2019 incident in Belmont, Massachusetts.
A Bolt caught fire in the driveway and the owner said strong fumes permeated the home during a three-hour fire requiring professional cleaning.
The owners also reported they suffered headaches from contact with the smoke.
Dealerships will update the vehicle's battery software from next week.
GM said until owners receive the dealer software update, they should change the charge settings to enable either "Hilltop Reserve" for 2017-18 vehicles or "Target Charge Level" for 2019 model year vehicles.
This will limit vehicle charging to 90 per cent.
