DETROIT – General Motors has announced that it will soon lift charging, parking and range restrictions on Chevrolet Bolt EV and EUVs that have been recalled due to the risk of battery fire.
2019 Bolts owners who have not yet received a battery module replacement can receive a software update from their dealer that will remove the restrictions starting Friday. The software will be available to 2017-18 and 2020-22 bolt owners within the next 30 days, GM said in an emailed statement Friday.
The new software significantly reduces the risk of fire by automatically setting the vehicle’s maximum state of charge to 80 percent, spokesperson Kevin Kelly said. Automotive News. The software reduces vehicle range but eliminates the need to follow previous GM guidelines. It allows owners to safely charge indoors overnight, park indoors after charging, and operate their vehicles within 70 miles of range.
The software also includes diagnostics to detect specific anomalies that may indicate a rare battery problem.
The recall includes more than 140,000 vehicles – each Bolt EV and EUV GM has built since 2016 – and could cost up to $ 2 billion depending on the number of module replacements required. Battery supplier LG Energy plans to cover the vast majority of the costs. The drastic recall has been a black eye for GM as it prepares to launch its next-generation electric vehicles, powered by its proprietary Ultium batteries, unlike the Bolts’ batteries. GM plans to deploy 30 models of electric vehicles around the world and invest $ 35 billion in the development of electric and autonomous vehicles through 2025.
Owners of 2019 Bolts who have not yet received replacement battery modules should make an appointment with their dealer as soon as possible to install this software, GM said.
Owners of other model year bolts will receive a letter from GM when the software becomes available for their vehicles. GM advises them to follow its previously published guidelines in the meantime.
GM started replacing battery modules in 2017-19 Bolts last month. The automaker plans to run separate diagnostic software on the 2020-22 bolts to determine if the modules need to be replaced. This software is not yet available.
