Over 600,000 Hyundai and Kia vehicles are being recalled to address a brake fluid leak that could start an engine fire.

The recall affects more than 440,000 Kia Optima midsize sedans, model years 2013-2015 and Kia Sorento SUV’s, model years 2015-2015.

Also affected are 151,000 Hyundai Santa Fe SUV’s., model years 2013-2015.

A brake fluid leak inside a hydraulic control unit for the vehicles’ anti-lock brakes can cause an electrical short that could cause a fire.
