The two recalls are related. A software glitch was triggered by a “malfunction in the software programming tool during servicing” for the prior recall, the NHTSA documents said. That might fail to notify drivers of defective battery parts that need to be replaced, according to the filing.

The National Highway Traffic Safety Administration said on Tuesday General Motors would recall 107 Bolt EV and EUV vehicles over a fire risk. The recall covers previously repaired Bolt vehicles from model years 2020-2022.

National safety regulators warn some Chevrolet Bolt owners to not fully charge their cars or park them in the garage because of fire risk.
