As I was driving down the road, I began to hear a loud, forceful noise. I assumed it was something in my trunk rolling against the rear seats. The noise kept getting louder, and I pulled over, very frightened, as several warning lights came on, including the low fuel light and check engine light, and the fuel gauge needle was past “E.” Before the incident, the GPM reading was 400. After a while, I made it home, but the car started making loud noises and then died. That’s when I noticed my back seats were lifted. I called Kia customer service and had the car towed to the Kia dealership on Seigan Lane, where it is now. Something needs to be done about this.

The contact owns a 2022 Kia K5. The contact stated that while attempting to reverse her vehicle and then shifting the gear shift into drive, the contact noticed her check engine warning illuminated, and she heard an abnormal noise coming from the front of the vehicle. The contact then parked the vehicle, went into the dealer, and let them know about the failure, but they offered no assistance. The vehicle was initially taken to the dealer, where the federal safety agency Campaign Number: 25V794000 (FUEL SYSTEM, GASOLINE) was completed. It was after the recall was completed that it was discovered that the check engine light illuminated, and the vehicle was not driving properly. The dealer took the vehicle back and provided a loaner. The contact mentioned that the engine was replaced, and then a catalytic converter was replaced. Most recently, the fuel oxygen sensor was discovered to be melted. The vehicle was repaired; however, the failure persisted. The manufacturer was notified of the failure and informed that the recall was complete with no other assistance offered. The failure mileage was 91,000.

A fuel system-related safety recall (SC356) remains incomplete on the vehicle. The vehicle was taken to an authorized Kia dealership in Jersey City, NJ, where I was informed that the recall repair had been completed. I paid for towing to the dealership for this repair. However, after picking up the vehicle, it immediately began exhibiting worsening symptoms, including engine shaking, rough operation while driving and idling, and prior stalling incidents. A check engine light also appeared after the visit. Upon further verification, the recall still shows as incomplete. This indicates that the recall repair was either not performed or not completed correctly. The issue appears to involve the fuel system, as the symptoms worsened after refueling and include unstable engine performance consistent with improper fuel delivery or air entering the system. This condition creates a safety risk due to potential engine stalling while driving, as well as the known recall risk involving fuel tank deformation and possible fire hazard. The problem has not been properly resolved by the dealership, and the vehicle is currently unsafe for normal use. The failed recall repair is available for inspection.

My 2022 Kia K5 GT-Line has had a recurring check engine light fault (P0471 — exhaust pressure sensor circuit) since approximately 9,874 miles in September 2022. The vehicle has been brought to the servicing Kia dealer a minimum of five times for this same fault across nearly 65,000 miles. It has never been permanently resolved. Most critically: dealer repair records from May 2025 (56,501 miles) confirm a technician identified fault code P047100, noted it as a history code, cleared it, test drove the vehicle, and returned it without performing any repair and without informing me. Ten months later, the same dealer presented this identical fault as a $1,121.07 customer-pay repair on a vehicle under active 10-year/100,000-mile powertrain warranty. The repair was only approved after I contacted Kia Consumer Affairs directly — the dealer had not contacted them despite claiming otherwise. The February 2026 repair failed within 15 minutes of pickup. I made five documented phone calls to the dealer over 33 days reporting the failure. No action was taken. The April 2026 repair — sensor and hose replacement — failed within one hour of pickup on April 1, 2026. Of additional concern: Recall SC288/SC288A (Fuel Tank Inspection and ECM Re-Update) was performed on this vehicle twice — July 2024 and August 2025. The ECM governs the exhaust pressure sensor circuit. The P0471 fault first appeared in dealer records between these two recall dates and has persisted through both completions. CARFAX confirms the April 2026 repair involved the engine/powertrain computer module. I am requesting the federal safety agency investigate whether SC288/SC288A is connected to recurring P0471 faults in 2022 Kia K5 vehicles. Kia Consumer Affairs Case escalated April 2, 2026.

STATEMENT OF FACTS: I presented my Kia K5 for two safety recalls (SC356 and SC263) with an active Check Engine Light for code P047100 (Exhaust Pressure Sensor). I informed the service advisor, Aliyah, that this code is a symptomatic secondary fault of the pressure irregularities addressed in Recall SC356, which explicitly lists an "Illuminated Check Engine Light" (MIL) as a primary warning sign. The dealership dismissed my technical assessment—which was backed by advanced AI data analysis. After the software update was performed, the advisor claimed the code remained "active," thereby "proving" it was unrelated to the recall. Based on this, I was charged a $248 diagnostic fee and told I needed a $534.02 out-of-pocket hardware repair for a "physically failing" differential pressure sensor that was allegedly reading 2 HPA against a spec of 23.09 HPA. EVIDENCE OF ERROR: Upon taking delivery of the vehicle, the Check Engine Light was completely extinguished. If the light were truly "still active" after the update, as I was told to justify the fee, the fault would have been present at pickup. Since then, I have driven over 120 miles (including multiple cold-start drive cycles between [XXX] and my place of work) with a 100% clear dashboard. My XXX App confirms the XXX fault is resolved, while the recalls remain "Open" administratively. REGULATORY VIOLATION: Under 49 U.S.C. Chapter 301, a manufacturer must remedy a safety defect without charge. A software "Logic Update" cannot physically repair a broken pressure sensor. The fact that the fault disappeared immediately following the update proves the sensor was functional and the fault was caused by the recall defect. By misdiagnosing a recall symptom as a non-covered hardware failure, the dealer effectively charged me for a federal safety repair. I request an investigation into these "diagnostic gatekeeping" practices and a full refund of the $248.00 fee.

My 2022 Kia k5 has gone into limp mode multiple times now while I am driving in addition to when it starts up. Check engine light, AUTOHOLD, EPB, traction control, etc. all aluminate on my dashboard. Car drives very rough and doesn’t want to accelerate or shift. Huge safety issue. Dealership said it was the throttle body assembly. Paid to have it replaced and the issues still persists. I have read multiple other comments with the same issue and dealerships have no idea what the issue is or how to correctly diagnose. Error codes were P00BD00, C136081, and C174181.
