Hyundai and Kia are recalling roughly 591,000 vehicles in the United States due to a brake fluid leak. This fluid may leak internally inside the Hydraulic Electronic Control ECU which, over time, could trigger an electrical short. An electrical short in the HECU increases the risk of an engine compartment fire while driving and Hyundai has added that a fire could even happen if the car is not turned on.
Vehicles involved in the recall are 2013-2015 Kia Optima models, totaling 283,803 vehicles. The recall also involves 156,567 Kia Sorentos from 2014 and 2015 and 151,000 Hyundai Santa Fe models from the 2013-2015 model years.
There have been 15 reports of engine fires in Hyundai and eight in Kia vehicles because of this issue. Owners of these models of Kia or Hyundai vehicles can check the NHTSA recalls website to find out if their vehicle is affected.
