Kia Cadenza 2019 — Reported problems

While operating the vehicle, the engine suffered a catastrophic internal mechanical failure, resulting in an immediate and dangerous loss of motive power on the road. A subsequent physical diagnostic scan at an authorized Kia dealership revealed manufacturer trouble code P008800 (Fuel Rail System Pressure-Too High) along with universal engine misfire codes P030100, P030200, P030300, P030400, P030500, P030600. The dealership confirmed that the internal engine failure includes a shattered piston. Code P008800 is the primary mechanical failure indicator for active manufacturer warranty campaign WTY 0034 (High Pressure Fuel Pump Failure). The defective high pressure fuel pump suffered a primary mechanical failure, spiking fuel rail pressures to dangerous limits, causing all six cylinders to misfire, and inducing low speed pre-ignition (LSPI). This extreme combustion anomaly directly fractured the engine's internal piston. The dealership is currently attempting to clear these diagnostic trouble codes and perform an oil change, which would actively destroy the physical and electronic evidence linking the safety recalled component failure directly to the engine's catastrophic destruction. This component failure poses a severe stall hazard and a risk of total engine failure while operating at highway speeds. Photographic proof of the official dealer diagnostic report has been preserved.

I picked up my Cadenza from the repair shop. They were repairing the sunroof controls because the sunroof was not operating properly. I was 24 miles away from the shop headed home from Temple, TX to Waxahachie, TX on [XXX]. It sounded like a shotgun was fired right above my head and scared me. I am surprised I didn't crash. I pulled over and the sunroof had a 2 foot hole in it. The shade was in the shut position so no glass made into the cab. No rock or any debris hit the vehicle. My mom was driving behind me and she said she saw a huge chunk of glass fly up from my car and hit her car. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
