2011 Kia Forte Recalls, Issues & Maintenance

The 2011 Kia Forte carries 3 open NHTSA recalls — most recently covering air bag/restraint control module and cooling unit and lines. Owners report 7 recurring issue clusters, led by “Engine knocking noise progressing to rod bearing failure.” Kia uses Hyundai Motor Group's powertrains, so service intervals mirror Hyundai's. Kia Promise covers the first 3 years / 36,000 miles of complimentary maintenance. Kia owners with the Theta II 2.0L/2.4L (Optima, Sorento, Sportage 2011-2019) should adhere strictly to oil intervals due to known oil-consumption issues in Kia TSBs.

AIR BAGS: AIR BAG/RESTRAINT CONTROL MODULE

Campaign #18V363000 · Jan 6, 2018

Issue: 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. Kia's number for this recall is SC165.

POWER TRAIN:AUTOMATIC TRANSMISSION:COOLING UNIT AND LINES

Campaign #16V070000 · May 2, 2016

Issue: Kia Motors America (Kia) is recalling certain model year 2011 Forte vehicles manufactured August 27, 2010, to November 11, 2010. The affected vehicles have a transmission fluid cooler hose that may have been improperly manufactured, resulting in a transmission fluid leak.

Risk: If enough transmission fluid leaks out, the transmission may not function properly and the vehicle may stop moving, increasing the risk of a crash.

Fix: Kia will notify owners, and dealers will replace the transmission cooler hose, free of charge. The recall began March 30, 2016. Owners may contact Kia customer service at 1-800-333-4542. Kia's number for this recall is SC129.

SERVICE BRAKES, HYDRAULIC:ANTILOCK/TRACTION CONTROL/ELECTRONIC LIMITED SLIP:CONTROL UNIT/MODULE

Campaign #23V652000 · Sep 25, 2023

Issue: Kia America, Inc. (Kia) is recalling certain 2010-2019 Borrego, 2014-2016 Cadenza, 2010-2013 Forte, Forte Koup, Sportage, 2015-2018 K900, 2011-2015 Optima, 2011-2013 Optima Hybrid, Soul, 2012-2017 Rio, 2011-2014 Sorento, and 2010-2011 Rondo vehicles. The Hydraulic Electronic Control Unit (HECU) may experience an electrical short, which can result in an engine compartment fire while parked or driving.

Risk: An engine compartment fire while parked or driving can increase the risk of injury.

Fix: Owners are advised to park outside and away from structures until the recall repair is complete. Dealers will replace the HECU fuse, free of charge. Interim notification letters, notifying owners of the safety risk, were mailed November 14, 2023. Owner notification letters were mailed March 29, 2024 through June 18, 2024. Owners may contact Kia customer service at 1-800-333-4542. Kia's number for this recall is SC284.

Estimated cost — typical U.S. ranges

Dealer

~$120–$160

~$60

DIY

Most shops do this free as a courtesy with any service. Don't pay separately if you can avoid it.
