Certain vehicles may be equipped with a 4-pin accessory trailer wiring harness kit that could fail. Over time, this could result in a short circuit that can cause the control module to overheat.
A short circuit can create a fire risk, even while the vehicle is parked and turned off.
Kia will notify owners by mail and instruct you to bring your vehicle to a dealership to inspect the vehicle for a trailer wiring harness kit. If necessary, the dealer will install a 15A fuse and a wire extension kit. Kia advises that if your vehicle has a tow hitch harness installed, you should park it outdoors, and away from other vehicles or structures until the recall repairs have been completed. As an extra level of protection, you or your dealer can also remove the "TRAILER" fuse in the under-hood fuse box.
