2022 KIA K5 problems

SEATS

On XXX, while traveling to [XXX], I experienced serious fuel system problems after filling my vehicle. The fuel gauge fluctuated from full to empty, and a loud pop caused the rear seat, where my two children were sitting, to lift upward. The vehicle would not accept more fuel despite the empty reading. I called AAA, but before the tow arrived, the gauge returned to normal, so I continued my trip. After returning to [XXX], I checked my Kia app and discovered active Recall SC356 describing a damaged check valve that could cause fuel tank expansion, rear seat lifting, and abnormal fuel gauge behavior—the same symptoms I experienced. On XXX, I brought the vehicle to The Kia Store in Louisville, advised them of the recall and my symptoms, and requested an inspection. Service Advisor Sidney Daub stated the issue was caused by a scratched muffler, not the recall, and no recall repair was performed. Relying on that assessment, I continued driving. From XXX, while traveling to [XXX], the same problems returned. Smoke came from the fuel tank area, fuel sprayed onto me when I opened the fuel door, and the vehicle became disabled and required towing home. I then took it to Kia Store East on June 10. There, [XXX] advised the failure was related to Recall SC356, and Haley informed me Kia Consumer Affairs would contact me. After weeks of communications, Kia advised on XXX that the vehicle was unrepairable and requested ownership documents. On XXX, Kia offered only to satisfy my loan balance through a buyback. I believe the dealership's failure to properly diagnose & repair the recall condition in April directly contributed to the later failure, safety hazards, towing expenses, and loss of my vehicle. I respectfully request that NHTSA investigate Kia's handling of Recall SC356 and the dealership's actions, & encourage Kia to consider a replacement vehicle, collateral swap, or another equitable resolution.

FUEL/PROPULSION SYSTEM

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.

FUEL SYSTEM, GASOLINE

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 NHTSA 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.

POWER TRAIN

The Integrated Thermal Management System (ITMS) in my Kia K5 GT (2.5T engine) has experienced a recurring internal electronic and mechanical fault. This is the third failure of this component. The failure causes the cooling system to malfunction, either by over-cooling or failing to cycle coolant once at operating temperature. ​Under acceleration—specifically when merging onto expressways—the vehicle suffers a sudden loss of power and enters 'limp mode' with a dashboard alert stating the engine is overheating. This creates an immediate safety hazard in high-speed traffic. When the fault occurs, the radiator fans lock at 100% duty cycle. This is a documented systemic issue with the Kia 2.5T powertrain (referenced by major automotive publications and multiple Technical Service Bulletins). ​Despite a prior Lemon Law settlement and an active 100,000-mile powertrain warranty, the manufacturer refuses to acknowledge this as a powertrain or emissions defect, attempting to charge out-of-pocket for a component that prevents the vehicle from passing state emissions and safety inspections."This was also cited in a 2023 issue of car and driver magazine long-term test with The Kia Sorento that shares the same engine and transmission combination This is a third time that part has failed for me with others had to replace that part over seven times The first time it happened it was at 8,000 mi it did not get fixed until 30,000 mi The second time it happened was at 51,000 mi The third time 75,000 mi

I was driving on the highway and my check engine light came on. I pulled over and it told it was from engine control system. I had a computer connected to it and it came back the idle control system rpm higher than expected.

NHTSA complaint #11736237 — an unverified report by a vehicle owner.

FUEL/PROPULSION SYSTEM

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.

FUEL/PROPULSION SYSTEM

The vehicle experienced an overheating condition involving the fuel system, which aligns with an active recall stating that a damaged check valve can allow air into the fuel tank, causing it to expand and come into contact with hot exhaust components, potentially melting the fuel tank. While operating the vehicle, this created a serious safety concern due to the risk of fuel tank damage, fuel leakage, and potential fire. This was not a minor issue, as it directly involved a component that could lead to a fire hazard. The vehicle was later evaluated and deemed unrepairable due to the severity of the issue. Because of this, the vehicle is not currently being used due to safety concerns. Despite the known safety risk and recall-related defect, the situation has not been properly resolved. The handling of this issue raises concerns given the potential for fuel system failure and fire risk associated with this defect. This complaint is being submitted due to the safety risk involving the fuel system and the potential for fire while operating the vehicle.

I bought a 2022 KIA K5 gt-line new and the horn stopped working less than a year later at 64,000 miles Gary Rome KIA assessed the repair and said KIA would not cover. I paid $169.00. In January 2026 my horn stopped working again. Ron Bouchard KIA assessed and said KIA would not cover repairs, I paid $819.98 myself. I have contacted KIA myself and with the assistance of the Ma Atty Gen'l office. I and the Atty Gen'l advocate have not received a reply from KIA. my out of pocket cost so far is $877.38 not including down time and inconvenience. KIA reportedly quietly acknowledged the horn issue in the K5 and extended warranty to cover repairs but did not or will not reimburse me my cost.

POWER TRAIN

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 NHTSA investigate whether SC288/SC288A is connected to recurring P0471 faults in 2022 Kia K5 vehicles. Kia Consumer Affairs Case escalated April 2, 2026.

POWER TRAIN

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.

The contact owns a 2022 Kia K5. The contact received notification of NHTSA Campaign Number: 25V794000 (Fuel System, Gasoline); however, while taking the vehicle to the dealer, it was determined by the dealer that the vehicle could not be repaired. The contact was not given any reason why the vehicle could not be repaired and was offered a buy-back option instead. The contact stated that the rear passenger seats were extremely hot. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The failure mileage was approximately 90,000.

UNKNOWN OR OTHER

The infotainment system in my 2022 Kia K5 began failing on or around early December, 2025, at approximately 44,000 miles and has continued to worsen. The vehicle is currently at approximately 47,000 miles. The screen displays the Kia startup screen repeatedly and does not fully load, flashing, becoming unresponsive, and ultimately causing distraction while driving. Audio may still function, but key features such as Bluetooth, Apple CarPlay, and auxiliary input do not work. The backup camera will either not function at all or will flash intermittently while reversing. This failure affects safe operation of the vehicle because it limits access to vehicle controls and creates distraction while driving due to the malfunctioning display. It also impacts visibility and usability of integrated systems that are expected to function reliably. The problem has been reproduced consistently and was evaluated by a Kia dealership. The dealership was unable to determine a clear cause for the failure but recommended full replacement of the infotainment system at a cost of approximately $6,700. There were no clear warning messages prior to failure. The issue has persisted despite attempts to reset the system and power cycle the vehicle. This appears to be a premature failure of a critical electronic system that should not occur at this mileage.
