GM Expands Chevrolet Bolt EV Recall, Adding $1 Billion In Costs

General Motors expanded a recall of its Chevrolet Bolt on Friday, announcing plans to repair thousands more of the electric autos in a move that will add $1 billion in costs.

The recall will address two manufacturing defects in electric battery cells, which can cause the cars to catch fire. The latest moves add to the $812 million in costs connected to the earlier recall of Bolt vehicles.
