Volvo Trucks North America and Mack Trucks are recalling nearly all the battery-powered electric trucks made over the past four years because of an issue that can cause a battery fire.

The recall is the fourth for the trucks since they entered series production in 2022. The latest recall affects 173 Volvo and nine Mack vehicles built between April 1, 2019, and Feb. 10, 2023.

Battery-powered electric trucks are still relatively new on the market. Some of the issues are consistent with new products. They develop bugs that need to be fixed, not unlike traditional diesel trucks.

The latest recalls for the two Volvo Group brands relate to an over-torquing of buss bars, according to a post on the National Highway Traffic Safety Administration website.
