DETROIT (CBSDFW/AP) — Korean automakers Hyundai and Kia are recalling more than 591,000 vehicles in the U.S. to fix a brake fluid leak that could cause engine fires.

The recalls cover more than 440,000 Kia Optima midsize sedans from 2013 through 2015 and Kia Sorento SUVs from 2014 and 2015. Also covered are 151,000 Hyundai Santa Fe SUVs from 2013 to 2015.

The affiliated automakers say brake fluid can leak inside a hydraulic control unit for the anti-lock brakes, possibly causing an electrical short that can lead to fires.

Kia’s recall will start Oct. 15, while Hyundai’s will start Oct. 23. Dealers for both companies will inspect the control units for leaks and replace them if needed at no cost to owners.

This isn’t the first recall for the company for a similar issue.

In January 2019, the automakers recalled about 168,000 vehicles to fix a fuel pipe problem that can cause engine fires. The problem stemmed from improper repairs during previous recalls for engine failures.
