The high pressure fuel pipe that connects to the fuel pump outlet may have been damaged, misaligned or improperly torqued during the engine replacement procedure, possibly causing a fuel leak.

Defect: Kia Motors America (Kia) is recalling certain 2010-2013 Kia Forte, Forte Koup, 2011-2013 Kia Optima and 2011-2012 Kia Optima Hybrid and Sedona vehicles. 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.
Risk: 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. For all other affected vehicles, Kia will instruct dealers to install the extension wire harness kit. The recall began September 28, 2018. Owners may contact Kia customer service at 1-800-333-4542.

Defect: Kia Motor Company (Kia) is recalling certain 2011-2014 Optima, 2012-2014 Sorento and 2011-2013 Sportage vehicles. Machining errors during the engine manufacturing process may cause premature bearing wear within the engine.

Risk: 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 will send an interim notification to owners in May 2013. When parts are available, owners will receive a second notification and dealers will replace the stop lamp switch, free of charge. Owners may contact Kia at 1-800-333-4542. Kia's recall campaign number is SC098.
