FUEL SYSTEM, GASOLINE:DELIVERY:HOSES, LINES/PIPING, AND FITTINGS19/12/2018

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.

High theft risk

#18 most stolen in 2025

The Kia SPORTAGE was the #18 most-stolen vehicle in the United States in 2025, with approximately 5,700 thefts reported to law enforcement.

Kia Boys / TikTok theft vulnerabilityModel years 2010-2021 Hyundai and Kia vehicles without engine immobilizers were widely targeted starting in 2022 after a viral TikTok exploit. If you own this vehicle, verify it has an ignition immobilizer or install a security upgrade. Hyundai and Kia both offered free software updates and steering-wheel-lock programs for affected models.

Recommended protection: engine immobilizer verification, steering wheel lock, GPS tracker, and comprehensive insurance coverage. Higher theft risk usually translates to higher comprehensive-coverage insurance premiums.
