General Motors Co. is recalling some battery-powered Chevrolet Bolt electric cars because they are at risk of catching fire, three years after a larger recall of the all-electric model for a similar hazard.
The latest action targets 107 bolts for the 2020 to 2022 model years, the company said in documents posted Tuesday on the U.S. National Highway Traffic Safety Administration’s website. That’s a small fraction of the 142,000 Bolt models that were subject to a previous recall due to a battery defect.
The two downloads are linked. A software problem was caused by a “malfunction in the in-service programming software tool” for the previous recall, NHTSA documents said. This may not notify drivers of defective battery parts that need to be replaced, according to the documentation.
The move comes as GM changes its approach from a one-size-fits-all battery strategy for its EVs.
