WASHINGTON, April 29 (Reuters) - General Motors Co
said it would launch a recall and software update on Thursday to
address a callback of nearly 69,000 Chevrolet Bolt electric
vehicles for fire risks and will replace battery module
assemblies as necessary.
The largest U.S. automaker announced the recall in November
after five reported fires and two minor injuries covering
2017-2019 model year Chevrolet Bolt EVs with high voltage
batteries produced at LG Chem Ltd's Ochang, South
GM said dealers will use "diagnostic tools to identify
potential battery anomalies and replace battery module
assemblies as necessary."
They will install "advanced onboard diagnostic software into
these vehicles that, among other things, has the ability to
detect potential issues related to changes in battery module
performance before problems can develop" it added.
GM said in November the vehicles pose a fire risk when
charged to full, or nearly full capacity. The Detroit automaker
said it had developed software that will limit vehicle charging
to 90% of full capacity to mitigate the risk, while it
determines the appropriate final repair.
GM said Thursday that once the software update is complete,
dealers will remove the 90% state of charge limitation and
return the battery to its previous 100% charging capability.
Owners of 2019 model year Chevrolet Bolt EVs will be able to
update the software starting on Thursday and 2017 and 2018 Bolt
EVs owners will be eligible by the end of May. GM said it will
make the diagnostic software standard in the 2022 Bolt EV and
EUV, as well as future GM electric vehicles, and will offer the
update for all other Bolt EVs on the road at a future date.
