2018 Kia Sportage Recalls, Issues & Maintenance

The 2018 Kia Sportage carries 3 open NHTSA recalls — most recently covering hoses, lines/piping, and fittings and control unit/module. Owners report 6 recurring issue clusters, led by “Excessive oil consumption and engine 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.

FUEL SYSTEM, GASOLINE:DELIVERY:HOSES, LINES/PIPING, AND FITTINGS

Campaign #18V907000 · Dec 19, 2018

Issue: Kia Motors America (Kia) is recalling certain 2011-2017 Optima, 2012-2017 Sorento and 2011-2018 Sportage vehicles that previously received an engine replacement under recall number 17V-224, warranty, or the Knock Sensor Detection System (KSDS) Product Improvement Campaign. 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.

Risk: A fuel leak in the presence of an ignition source can increase the risk of a fire.

Fix: Kia has notified owners, and dealers will inspect and replace the fuel pipe, as necessary, free of charge. The recall began January 17, 2019. Owners may contact Kia customer service at 1-800-333-4542. Kia's number for this recall is SC172.

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

Campaign #21V137000 · Apr 3, 2021

Issue: Kia Motors America (Kia) is recalling certain 2017-2021 Sportage and Cadenza vehicles. The electrical circuit in the Hydraulic Electronic Control Unit (HECU) may short-circuit, which can cause a fire in the engine compartment.

Risk: An engine compartment fire can increase the risk of injury.

Fix: Owners are advised to park outside and away from structures as a precaution until the recall repair is complete. Kia will notify owners, and dealers will replace certain fuses in the electrical junction box. Vehicles equipped with an electronic parking brake (EPB) will also receive a HECU software update.

Debris and moisture accumulation on the tow hitch harness module printed circuit board (PCB) may cause an electrical short, which can result in a fire.

Risk: A 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 inspect the vehicle, and, as necessary, replace the fuse and/or tow hitch harness module, free of charge. Owner notification letters were mailed August 11, 2023. Owners may contact Kia customer service at 1-800-333-4542. Kia's number for this recall is SC249.
