I am filing this complaint regarding Kia America’s handling of a safety recall and repurchase of my 2023 Kia K5 GT-Line (VIN: [XXX]. I purchased this vehicle used on XXX, and financed it through Capital One. After taking my vehicle to an authorized Kia dealership for the fuel tank valve safety recall, I was informed that my vehicle was unsafe to drive and could not be repaired. The dealership advised me that Kia would be repurchasing the vehicle. Kia has offered to buy back the vehicle, but the settlement being offered does not appear fair under the circumstances. Although Kia has determined that my vehicle is unsafe and unrepairable due to a manufacturer safety defect, I have only been provided with 15 days of rental vehicle coverage while Kia’s own repurchase letter states that the process may take 60 to 90 days to complete. This could leave me without transportation through no fault of my own. Additionally, Kia has refused to reimburse my $4,000 down payment or provide any additional compensation related to the loss of use of my vehicle. Their offer also includes a substantial mileage deduction under certain options, despite the fact that this repurchase is the result of a manufacturer safety defect rather than a voluntary sale or trade-in. I requested written clarification regarding my settlement options, rental coverage, loan payoff, and reimbursement of my expenses. Rather than answering my questions, Kia responded only that the offer was “firm” and compliant with Florida law, without addressing the specific concerns I raised. I am requesting that this matter be reviewed to determine whether Kia is handling this safety recall and repurchase fairly and whether consumers whose vehicles are deemed unsafe and unrepairable should receive adequate transportation assistance and fair compensation while waiting for the manufacturer to complete the repurchase process. I respectfully request assistance in reviewing Kia America’s handling this case. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA

The fuel tank expanded, the car was spitting out gas from where you are supposed to insert gas nozzle. my fuel tank expanded so bad from pressure my vehicle sensors malfunctioned my car did not tell me something was wrong, I heard a pop and my car was telling me I had no gas when I did. the insert area for gas to be pumped was swollen and couldn't shut my gas cap cover. I went to gas station and since my car said it was empty I attempted to add gas and it spit it back out immediately it could not take gas, so I called kia locations since I was in [XXX] with kids in my vehicle for halloween trick or treating. the recall papers I have in order says safety hazard was a FIRE. my car fuel tank could had made my car explode at any moment. my engine light did not come on all my car showed me was mile change and inaccurate amount of gas reading. the dealer has had my car since November 2025. I heard popping sounds when I would return home from work in the driveway but no warning. one Time in July of 2025 my engine light came on I went to autozone they gave me a code for something with fuel issue, light didn't stay on no longer than a few hours. kia has cost me so much mishap and unfair financial responsibility. it has been a nightmare. the person working my case I can only talk to in email, it has taken forever now I have a repurchase offer that I had to fight for. they are trying to make me return my rental before completion of repurchase offer which offer stated could take longer than 30 days. this is so unfair. it seems illegal.

NHTSA complaint #11737762 — an unverified report by a vehicle owner.
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

The display is shows a "Check Oil Level" error. It comes on then goes off regularly. I have verified that the oil level is OK. Took it into the dealer and he said that this is a common issue and a software fix is coming. The car only has less than 2K miles. I depend on the engine displaying error messages, but they need to be real ones. Online complaints indicate that this is a common error and there seems to be no fix.

My brand new 2024 Kia K5 has been at Kia of temple hills since February 23, 2026. The dealership has stated they do not know how to diagnose or repair the issue and indicated they needed a special diagnostic tool from the manufacturer. The vehicle has now been out of service for an extended period with no repair timeline provided and no communication from them at all. I also have not been provided a loaner or rental vehicle during this timeframe. While driving with my toddler child the steering wheel gets tight the speedometer isn’t reading correctly. Dashboard lights up like a Christmas tree with almost all warning lights on and messages to check every system: from tire pressure to forward collision to RearCross-TrafficSafety and the list goes on
NHTSA complaint #11729327 — an unverified report by a vehicle owner.
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.
NHTSA complaint #11728917 — an unverified report by a vehicle owner.
Shortly after a routine oil change performed at a Kia dealership, I discovered a significant oil leak underneath the vehicle the following day. Within a short period of time, the vehicle began experiencing engine-related issues including a cylinder misfire, noticeable shaking while driving, and loss of power, particularly when accelerating or driving on inclines. The vehicle also displayed a check engine light and a warning related to 12-volt battery drain. In addition, I noticed a strong burning odor coming from the engine area, which raised concerns about a possible fluid leak or internal engine issue. These conditions created a safety concern because the vehicle would hesitate and lose power during normal driving, which could increase the risk of an accident, especially in traffic or when merging or climbing inclines. The vehicle was returned to a Kia dealership for inspection. I was informed that a cylinder issue was suspected; however, only a temporary repair involving a coil swap was performed. No comprehensive diagnostic testing was completed to confirm the root cause of the problem. After the repair, the vehicle continued to exhibit abnormal behavior, including shaking and lack of power. Due to ongoing safety concerns and lack of confidence in the vehicle’s reliability, I stopped driving the vehicle. This issue occurred at relatively low mileage, raising concerns about a potential engine defect or unresolved mechanical failure.
