On certain vehicles equipped with a 2.0 L NU GDI or 2.4 L Theta II MPI engine, an engine compartment fire could occur while driving. Kia is conducting this recall as a preventative measure to prevent fire risk due to potential fuel leaks, oil leaks and/or engine damage. In some situations, you may notice any of the following symptoms: there could be an abnormal knocking noise from the engine; the check engine light and/or the oil pressure warning light could turn on; you may smell fuel, burning or smoke; or you may notice oil leaks. If you continue to drive the vehicle with these symptoms, the engine could fail and/or a fire could occur. An engine failure can cause a sudden loss of power with an inability to restart.
Note: For the Optima model, only the Optima Hybrid is affected by this recall.
An engine compartment fire can create a risk of injury. A sudden loss of engine power could increase the risk of a crash.
Kia will notify owners by mail and instruct you to take your vehicle to a dealer for an inspection of the engine and engine compartment. The dealer will inspect for fuel and/or engine oil leaks, perform an engine test and make any repairs, including engine replacement, if necessary. Kia will also perform a Knock Sensor Detection System (KSDS) software update free of charge, once it is available for your vehicle. This update will detect and prevent engine damage from worn connecting rod bearings.
On certain gasoline and hybrid engine vehicles, the circuits within the airbag control unit may become damaged. This could cause the airbags and seat belt pretensioners to not deploy in certain collisions where deployment is warranted, which could increase the risk of injury to vehicle occupants. Correction: Dealers will install a wire harness kit between the ACU connector and vehicle harness connector as necessary. Note: This recall does not affect the 2013 model year Optima Hybrid.
On certain vehicles, the brake pedal stopper pad material could deteriorate over time and allow the stop lamp switch plunger to remain extended when the brake pedal is released. This could result in the stop lamps illuminating continuously, which would result in following road users being unaware of the driver's intentions. Additionally, it could result in activation of the engine management system’s brake pedal override feature, the illumination of the traction control warning lamp, and/or the ability to move the shift lever without depressing the brake pedal, which could result in unintended vehicle movement. These conditions could increase the risk of a crash causing injury and/or damage to property. Correction: Dealers will replace the brake pedal stopper pad.
