“NHTSA Vehicle Safety Complaint Statement Vehicle: 2018 Kia Stinger Premium 2.0L Turbo VIN: [XXX] Component: Fuel System, Gasoline: Delivery: High Pressure Pump [1, 5] Recall Campaign Reference: 2023 Kia High-Pressure Fuel Pump Safety Recall [5] 1. Failure of Initial Recall Remedy & Active Safety Hazard This vehicle was subject to the 2023 Kia High-Pressure Fuel Pump (HPFP) Safety Recall due to a known manufacturer defect that causes fuel pressure drops, stalling, and loss of motive power on the highway. I originally presented the vehicle to an authorized dealership (Kia Cherry Hill) for execution of this critical safety recall. Instead of physically replacing the defective mechanical pump as required by federal safety guidelines, the dealership only performed a corporate software update and released the vehicle back into commerce with the defective hardware still active. This failure to execute the physical remedy allowed a known, high-risk safety hazard to remain completely unmitigated in the vehicle. 2. Recurrence of Failure and Catastrophic Incidents The unreplaced defective safety component inevitably failed, causing the vehicle to suffer severe pressure…”
“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…”
“While driving the steering wheel jerks back and forth as if it's trying to help assist in keeping in lanes even with the lane assistant off and it doesn't matter what speed it jerks the whole time. The steering wheel will also move on its own back and forth while in a parked position too. It's very dangerous because it's trying to jerk you all around the road at no matter what speed you're doing.”
