Kia Stinger hesitation problems

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)

My 2022 Kia Stinger first went into the dealership because it would not accelerate properly even at full throttle, creating an immediate safety risk in traffic. Over multiple visits, the dealership replaced the ECM, ABS module, brake booster, vacuum pump, and a fuel injector, and confirmed repeated electrical shorts across major systems including throttle control, braking, and fuel delivery. Despite months of repairs, the loss of power, brake assist issues, ABS faults, and electrical failures continued, and the dealership never identified the root cause. The problems were reproduced and documented by the dealer, the vehicle was inspected multiple times on behalf of the manufacturer, and warning lights and drivability symptoms appeared before each failure. The vehicle is currently not in my possession, and all replaced components are available for inspection. The combination of engine hesitation, brake system failures, and repeated electrical shorts makes the vehicle unsafe and unreliable to operate.

My dealership confirmed that the recall parts are on national backorder and cannot repair the vehicle.

Dealer stated that the GDI pump has failed and that is not a common issue. My car started shuddering as I was driving in the interstate I5 north at 70mph, then the car stalled in the middle of the freeway, gas pedal was useless, if it was not because my speed was 70mph and the force of the speed keep my car moving for a little I would probably be hit by a truck putting my life and others at risk. Car was towed back to the dealer, very strong smell of gas and smoke was coming from underneath it, engine lights came on after it stalled a second time while parked on the side of the road. Only signs noticed was the shuddering one day prior to this incident but car did not stall and I thought It was because it needed oil change, other was hesitation to start while cold, after a second attempt it would start without problem. all those signs were not long lasting nor repetitive (shuddering happened only ones prior the day of the incident and ones seconds before the incident).

Just purchased a 2021 kia stinger gt awd new about a month ago. Just over 1000 miles on it now and encountered a concerning issue. Sitting at a stoplight with the auto start/stop off, traction control off and in sports mode, I pressed the gas pedal and there was a slight hesitation followed by a pretty forceful lurch forward. As I approached the next stoplight several hundred feet further ahead the car completely stalled out. I took it to the dealer and they could not duplicate it... Of course.

On feb 18, 2020 the car had a throttle hesitation and cut off in traffic while turning through an intersection and when started again had check engine light and car went into limp home mode. Car had error codes p061b, p0172, p0175, p2180, p2178. Kia advised to not drive the car and have it towed to dealer. I was told there was a loose wire connection and dealer supposedly fixed it. On march 23, 2020, car was running with rough idle and check engine light came on pulling codes p0108 and p0068. Car was able to be driven to dealer and dealer could not find the issue. On september 25, 2020, car had rough idle and check engine light and pulled code p0068. Car was able to driven to dealer and dealer could not find the issue. Dealer said maybe it was related to k&n air filters so at their advice and replaced them with stock air filters. January 26, 2021, car had throttle hesitation on the highway and when on the exit ramp the idle was jumping between 1000 and 1500 RPM. Check engine light came on and car went into limp home mode and pulling error codes p061b, p0172, p2178, p2180 which were the same codes from february 18, 2020. Car was towed to dealer january 27, 2020, and for two days the dealer has not been able to find the issue. I do not consider this car safe to drive. There's an electrical issue that can not be found and not knowing if car is going to stall or go into limp home mode is a terrifying way to drive.
