(Reuters) -Kia America is recalling 137,256 vehicles in the United States over concerns that piston oil rings may have been manufactured incorrectly, which can result in engine damage, the National Highway Traffic Safety Administration said on Tuesday.

The recall affects certain 2021-2023 Seltos and Soul vehicles, the auto safety regulator said.

Dealers will inspect and replace the engine as necessary and install piston-ring noise sensing system software, free of charge, it said.
