Defect
Kia is conducting a service campaign to inspect and upgrade the safety plug fuse. On certain Optima Hybrid (HEV) models, the safety plug fuse could blow and cause a loss of hybrid system power while driving at low speeds. Additionally, installing an incorrect aftermarket fuse could cause overheating.
Safety Risk
A loss of power to the wheels could increase the risk of a crash. Using an incorrect aftermarket fuse could create the risk of a fire.
Remedy
Kia will notify owners by mail and instruct you to take your vehicle to a dealership to inspect the vehicle for an aftermarket fuse and replace the 125-A safety plug with one that has a 150-A rating.
