What is wrong
Issue:
Kia Canada is conducting a Product Improvement Campaign that provides an update to the engine control module to detect potential problems before an engine fails. An engine failure could cause a sudden loss of power with an inability to restart.
Note: This campaign only affects Optima Hybrid models equipped with a 2.4 L MPI engine.
Safety Risk:
A sudden loss of engine power could increase the risk of a crash. An engine failure could also create the risk of a fire.
Corrective Actions:
Kia will notify owners by mail. Owners will be instructed to take their vehicle to a dealer to update the software for the engine control module.
Note: Kia recommends that you should always follow the correct vehicle maintenance schedule, which is printed in the Owner's Manual. If you experience unusual engine noise, reduced power, or a check engine/oil warning light, Kia advises you to immediately visit a Kia dealership to have your vehicle diagnosed.
