FAILED COMPONENT: Fuel rail pressure sensor (DTC P019100), 2025 Kia Sorento. Dealer (Kia of Glendale) replaced it [redacted]; the original part should be with the dealer or Kia. I have both repair orders and videos of two incidents. SAFETY RISK: On [redacted], climbing a hill on [[redacted]], the car would not exceed ~14 mph. 5-10 minutes later, entering the freeway, it would not exceed ~12 mph. On [redacted] recurred: the car lurched, dropped from ~20 mph, surged to ~33 mph, then lost speed to 0. My wife pulled...

over and it shut off once stopped. Shortly after, it lost power on a hill and regained it with a lurch. Both on video. No crash, fire or injury. REPRODUCED/CONFIRMED BY DEALER: Not at first. I brought it in [redacted] and was told [redacted] that a 50-mile test drive found nothing, but the repair order shows 26,319 in and 26,321 out: 2 miles. It failed again [redacted] and was towed in. The dealer then pulled P019100 and replaced the sensor. That repair order says a road test was done but gives no distance (26,594 in, 26,602 out: 8 miles total). OTHER INSPECTIONS: Kia America consumer affairs reviewed my complaint and paperwork. No police or insurance involvement. WARNING LAMPS: None. No lights or messages appeared before or during any failure. The first symptom was sudden loss of acceleration on [redacted]. I am filing so NHTSA has this on record, including the gap between the claimed 50-mile test and the documented 2 miles, whether or not the repair resolves the defect. I am concerned that the same fault could affect other Sorento owners, because the sensor failed without any dashboard warning and left the car unable to maintain highway speed. The first dealer visit also failed to catch it, which suggests the problem may be hard to reproduce in a short test. I am asking NHTSA to review this report alongside any other complaints about fuel rail pressure sensor failures on this model. My wife stopped driving our son in it after the incident.
