2018 Kia Stinger: sudden loss of power

Filed Nov 2, 2026 · Fuel system · MO

Vehicle Safety Complaint – 2018 Kia Stinger 3.3L Twin-Turbo I am filing a safety complaint regarding my 2018 Kia Stinger 3.3L twin-turbo due to a suspected failure involving the high-pressure fuel pump and high-pressure fuel pipe. While driving, my vehicle began hesitating and sputtering while stopped at a traffic light. The vehicle subsequently became unable to start. The engine cranks but will not remain running. The vehicle was taken to an independent repair facility for diagnosis. The mechanic tested the vehicle by manually supplying fuel, and the engine started but only ran for a few seconds before shutting off. The mechanic suspects a failure involving the high-pressure fuel pump and high-pressure fuel pipe. I am concerned about the safety implications of this failure because the vehicle experienced hesitation and sputtering while operating in traffic. A fuel-system failure that causes an engine to lose power or shut off unexpectedly could create a dangerous situation for the driver and other motorists. I contacted Kia Customer Care and provided my VIN. Kia informed me that there were no open recalls applicable to my vehicle and declined goodwill assistance. I am requesting that the federal safety agency document this complaint and review whether the high-pressure fuel pump and fuel pipe failures in 2018 Kia Stinger 3.3L models warrant further investigation or a safety recall. Vehicle: 2018 Kia Stinger 3.3L Twin-Turbo VIN: [XXX] Reported symptoms: Hesitation, sputtering, crank-no-start condition, and engine shutting off shortly after starting. Suspected components: High-pressure fuel pump and high-pressure fuel pipe. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
