NHTSA lists 3 safety recalls and 165 owner complaints for the 2018 Kia Sportage. Most complaints involve engine (91) and electrical system (30). The EPA rates it 21–26 mpg combined, and NHTSA gives it 5 stars overall.
Kia America, Inc. (Kia) is recalling certain 2016-2022 Sorento, 2021-2022 Sorento Hybrid (HEV), 2022-2023 Sorento Plug-In Hybrid (PHEV), and 2017-2022 Sportage vehicles equipped with a tow hitch harness installed as original equipment, or purchased as an accessory through a Kia dealership. 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.
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.
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.

“The vehicle suffered a primary connecting rod bearing failure covered under the Theta II class action warranty campaign. A brand-new warranty engine long-block was installed by an authorized dealership. Immediately upon vehicle pickup, the brand-new engine began exhibiting an un-metered acceleration defect. While stationary and idling in Park (P), the engine aggressively revs on its own without any operator input on the gas pedal. This malfunction caused the vehicle to violently surge and physically lurch forward several inches while in Park. This un-metered acceleration is an active, unpredictable driving hazard both in parking environments and in traffic, posing an immediate risk of a collision or pedestrian injury. The manufacturer has been notified but has failed to transmit a diagnostic pre-authorization to an alternative service center to safely inspect this powertrain hazard.”
“I have spent two months trying to get my keys re-programmed to the system and the dealership informed me that the system has been "bypassed" somehow with no solution. This is after my account had been taken over and at one point the vehicle was being remotely controlled. I am out $500.00 for keys that cant work and this is a safety issue as I cant remotely lock or unlock my own vehicle or use the panic button. There have been people who gained access to the vehicle because somehow they have access to it remotely where I do not. This allowed them to brick the infotainment center and navigation. This is also an issue as this means they cant be utilized.”
