General Motors again issued an urgent recall of some Chevrolet Bolt electric cars and SUVs that it previously repaired for battery fire risk.

GM replaced defective battery modules in the vehicles in an August 2021 recall. It now says installed diagnostic software may have failed and needs to be replaced. Until it is, it says the battery could ignite if fully or nearly fully charged.

Meanwhile, it urges owners of the 2020 to 2022 Bolt EVs and 2022 Bolt EUVs, or subcompact SUVs, to set their target charge level to stop at 90%, charge them more often, avoid using the battery down to 70 range miles, park them outdoors after charging, and avoid charging indoors overnight.

GM is scheduled to mail recall notices to the 107 affected owners on Dec. 16.

In May the automaker and battery supplier LG agreed to give owners of certain recalled Bolts up to $1,400 each to settle a class-action lawsuit due to recalls over battery fires, according to news reports.
