2011 Kia Optima recalls
Electrical short can start engine fire
Fire riskAn electrical short in the brake system's control unit (HECU) can cause a fire in the engine compartment, either while the car is parked or while driving. Such a fire can lead to injury.
Fix: Until the repair is done, park outside and away from buildings, and the dealer will replace the HECU fuse free of charge.
Recall 23V652000 · Sep 2023Fuel pipe may leak, causing fire risk
Fire riskDuring an engine replacement, the high pressure fuel pipe at the fuel pump may have been damaged, misaligned, or under-tightened. This can cause a fuel leak, and fuel near an ignition source can start a fire.
Fix: The dealer will inspect the fuel pipe and replace it if needed, at no cost to you.
Recall 18V907000 · Dec 2018Air bag / restraint control module
In the event of a crash, the air bag control unit (ACU) may short circuit, preventing the frontal air bags and seat belt pretensioners from deploying. If the frontal air bags and seat belt pretensioners are disabled, there is an increased risk of injury to the vehicle occupants in the event of a vehicle crash that necessitates deployment of these safety systems.
Fix: Kia will notify owners. For model year 2011 Sedona vehicles, Kia will instruct dealers to verify the ACU part number and, if necessary, install an extension wire harness kit between the ACU Connector and the Vehicle Harness Connector.
Recall 18V363000 · Jun 2018Engine
Machining errors during the engine manufacturing process may cause premature bearing wear within the engine. Bearing wear may result in the engine seizing, increasing the risk of a crash.
Fix: Kia will notify owners, and dealers will inspect the engine assembly, and replace the engine if necessary, free of charge.
Recall 17V224000 · Mar 2017Switch
Originally, in April 2013, Kia recalled 623,658 model year 2007-2010 Rondo and Sportage, model year 2007-2011 Sorento, model year 2007 Sedona, model year 2010-2011 Soul, and model year 2011 Optima vehicles. In September 2013, Kia informed the agency that it was adding an additional 356,719 vehicles to this campaign. The total number of vehicles being recalled is now 980,377. In the affected vehicles, the stop lamp switch may malfunction. A malfunctioning stop lamp switch may cause the brake lights to not illuminate when the brake pedal is depressed or may cause an inability to deactivate the cruise control by depressing the brake pedal. Additionally, a malfunctioning stop lamp switch may also result in intermittent operation of the push-button start feature, affect the operation of the brake-transmission shift interlock feature preventing the shifter from being moved out of the PARK position and cause the Electronic Stability Control (ESC) malfunction light to illuminate. Failure to illuminate the stop lamps during braking or inability to disengage the cruise control could increase the risk of a crash. Additionally, when the ignition is in the 'ON' position, the transmission shifter may be able to be moved out of PARK without first applying the brake. This may lead to unintentional movement of the car which may increase the risk of a crash.
Fix: Kia's recall campaign number is SC098.
