I am filing this complaint regarding the handling of a fuel tank recall involving my 2023 Kia K5 GT-Line. On XXX, I brought my vehicle to Kia Rockwall in [XXX], after being informed of an issue related to a fuel tank recall. I was told that my vehicle could not be returned to me and that Kia would pursue a buyback instead. Before this incident, I had spent approximately $1,200 on repairs related to the issue, including replacing the charcoal canister. These repairs occurred the previous month. I am concerned about the circumstances surrounding the defect, the expenses I incurred attempting to address the problem, and the handling of the vehicle once it was brought in for the recall. I was initially told that a case manager would assist with arrangements. On XXX, a case manager contacted me, and I explained I could not afford to pay for a rental vehicle out of pocket. I was subsequently informed that I would need to pay for a rental through Enterprise and seek reimbursement from Kia. I explained again that this was not financially possible. On XXX, I received a further response, and Kia America ultimately stated that if I could not rent a vehicle under its specified conditions or pay for one out of pocket, it would not provide a rental. As of XXX, I remain without my vehicle and without a transportation arrangement that I can afford. I am requesting that the federal safety agency review the safety defect and recall associated with my vehicle, including whether the recall remedy and handling of affected vehicles are adequate and whether the circumstances warrant further review. I would also like my experience documented as part of the broader record of complaints concerning this recall. I can provide repair receipts, dealership communications, and correspondence with Kia America to support the timeline above.

The vehicle is grounded at the dealership due to the federal safety agency Campaign 25V794 (Kia Recall SC356). The vehicle's fuel tank has critically expanded and swollen, causing permanent structural and chassis deformation inside the vehicle. The dealership service department has documented this structural damage, confirmed the vehicle is entirely unsafe to operate due to an immediate fuel system fire hazard, and stated the vehicle is likely unrepairable. The manufacturer is currently holding the hazardous vehicle but is failing to provide immediate alternative transportation, leaving the consumer stranded and creating severe financial hardship. I do not have the financial means to pay rental car fees up front for an extended and undetermined amount of time while waiting for Kia to decide the next step. All of the issues with the vehicle are directly related to the manufacturer defect. My safety was at risk while operating the vehicle due to a severe fire risk.

I brought my 2023 Kia K5 to Citrus Kia in Ontario, California on 2/20/2026 for two safety recalls, including Recall SC356 involving a defective fuel check valve that can cause the fuel tank to expand, melt, and potentially catch fire. When I picked up my vehicle on XXX, I was given a repair invoice stating that both recalls had been completed. Four months later, I received another recall notice by mail for SC356. After contacting Kia corporate, they confirmed that Citrus Kia had never completed the recall, despite providing me with paperwork stating that it had been done. I made multiple attempts to contact the dealership for an explanation but my calls were never returned. Kia corporate also had difficulty reaching the dealership. They ultimately confirmed with Citrus Kia that the recall had NOT been performed and instructed me to have it completed at another dealership. This was not a minor paperwork error. Citrus Kia falsely represented that a serious safety recall involving a potential fire hazard had been completed when it had not. I have the dealership's own repair invoice documenting that they claimed the work was finished. I also have a voicemail recording from Kia corporate stating they were told by Citrus Kia that the recall was actually not completed. What is most alarming is that Kia corporate never asked the dealership why they provided an invoice stating the safety recall was completed when it had not. Attachments: page 3 of invoice from 2/23/2026 shows Recall SC356 as completed; 2 screenshots from the federal safety agency and [XXX] on 7/23/2026 shows Recall SC356 as not completed.

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
