Defect
On certain vehicles, moisture can enter the brake Hydraulic Electronic Control Unit (HECU) and cause a short circuit.
Safety Risk
A short circuit could create a fire risk. This can happen even if the vehicle is parked.
Remedy
Kia will notify owners by mail and instruct you to take your vehicle to a dealer to install a relay to power off the HECU when the vehicle is turned off. Kia recommends that you should park your vehicle outdoors, and away from other vehicles or structures until the recall repairs have been completed.
