The contact owns a 2023 Kia K5. The contact received notification of NHTSA Campaign Number: 25V794000 (Fuel System, Gasoline). While driving approximately 45 - 50 MPH, the vehicle shook violently, went into LIMP Mode, and failed to accelerate above 10 MPH. The contact stated that the vehicle stalled. The vehicle was towed to the dealer, and the fuel rail sensor was replaced. However, the fuel tank became deformed and bent the subframe, which the dealer deemed unrepairable. The manufacturer was notified of the failure by phone. The failure mileage was approximately 102,000.

ENGINE
I bought a 2023 Kia K5 GT vehicle as a CERTIFIED PREOWNED from Rick Case KIA Sunrise, FL. I paid $30,000.00 + an extended warranty for about $4,000.00, traded in my vehicle (for $9,000.00) and put a down payment of $5,000.00. Within two days of buying the vehicle in April of 2025 my car was back at the dealership in the service department for transmission issues. My vehicle has had 4 total transmissions and it is 3 years old (original transmission, 3 replacement transmissions). SHOCKER - it is STILL having transmission problems. I have NEVER had a good drive in this vehicle. I filed a request for a buy back with Kia Customer Care and they told me I did not meet the requirements. My car has been in the dealerships service centers 9 times due to transmission issues that continue arrising since I bought the vehicle about a year and a half ago. Kia Customer Care stated the only option was to open a "tech line" with Kia from the dealership directly so again I dropped my car off for over a week and they could not replicate the issue to start the tech line. I took a 45 minute test drive with the manager and duplicated it twice but the manager stated they could not feel it and sent me home with my vehicle. The vehicle stops accelerating all together in the middle of traffic, shudders when trying to speed up, sounds like and feels like the entire engine is going to drop out of the car to the floor. You can feel the gears slip. Even though it is more infrequent now, it still happens and I am afraid to drive my car.

FUEL/PROPULSION SYSTEM
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 NHTSA 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.

UNKNOWN OR OTHER, ELECTRICAL SYSTEM
My 2023 Kia K5 GT has an intermittent and unpredictable audio defect which the vehicle suddenly and spontaneously produces an extremely loud static-like noise through all speakers in the car, immediately upon starting the vehicle. This is not related to the radio, car play, phone connection, weather, etc. Adjusting the volume dial does not effect the issue either, for example. Shutting the car off, stops it momentarily, but will return upon starting it. The only way to stop the issue is to either disconnect the battery or pull the main fuse to the dash, resetting the car. The issue has been occurring for 3 years. With multiple videos of the issue happening. The noise is loud enough to cause medical damage, especially to a child or infant. This will put my newborn infant at risk of medical damage to her ears due to the decibel of the issue which is a safety issue. Kia of Greer South Carolina, has had the vehicle on numerous occasions and not been able to fix the car or made any attempts to fix the issue. I have escalated a case with Kia North America customer care due to the nature of it being a safety concern. No one has inspected the vehicle at this time outside of the dealerships I have taken it to.

FUEL SYSTEM, GASOLINE
The contact’s son owns a 2023 Kia K5. The contact stated the vehicle was previously included in NHTSA Campaign Number: 25V794000 (Fuel System, Gasoline), and the vehicle was repaired. A day or two after the recall repair was completed, the check engine warning light illuminated. The vehicle was returned to the dealer to be diagnosed, and the contact was informed that the fuel tank could expand and explode. The contact was informed that the fuel tank and fuel pump needed to be replaced. The vehicle was repaired. The contact stated that after driving 10 miles after the vehicle was repaired, the check engine warning light illuminated again. The vehicle was taken to Auto Zone, and similar fault codes were retrieved. The vehicle was not repaired after the latest failure. The manufacturer was made aware of the failure. The manufacturer referred the contact to the NHTSA Hotline to report the failure. The failure mileage was unknown.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER
The infotainment system in my Kia K5 has failed completely. The screen went black, causing the radio, infotainment features, and backup camera display to stop functioning. At times, the system will attempt to reboot on its own, but it does not return to normal operation and continues to malfunction. I have attempted to reset the system multiple times using the available reset methods, but none have resolved the issue. I took the vehicle to my local Kia dealership, where I was informed that the radio/infotainment unit itself is defective and needs to be replaced. The loss of the backup camera display is particularly concerning because it affects visibility and safety while reversing. I have also found numerous reports of similar infotainment and radio failures involving Kia vehicles, which makes me concerned that this may be a widespread defect rather than an isolated failure. I am requesting that this issue be reviewed and investigated as a potential vehicle defect.

FUEL/PROPULSION SYSTEM, UNKNOWN OR OTHER
The vehicle is grounded at the dealership due to NHTSA 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.

FUEL/PROPULSION SYSTEM
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 NHTSA and [XXX] on 7/23/2026 shows Recall SC356 as not completed.

FUEL/PROPULSION SYSTEM, ENGINE, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
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

FUEL/PROPULSION SYSTEM, SEATS, UNKNOWN OR OTHER
7/20/26 My 17 year old daughter was on the way to work and heard a loud noise like an explosion in her car. She, new to driving, scared and in a panic just assumed this was a blowout on a tire and pulled over to check the tires. All tires were clear so she proceeded to work cautiously, on her way home she noticed her check engine light had come on and noticed there was some road noise coming from the back. She then called me, note this is the first I heard of the situation. While on the phone with her I pulled up the CarFax to check when it had last been maintenanced, while doing that I saw for the first time TWO RECALLS on this car we had just purchased 3 months ago! By this time she was home and I instructed her to get out of the car while I Immediately called our local Kia dealership to schedule an appt to have the two recalls fixed (7/20/26 at 4:38pm). I gave the make and model to the service department and they informed me they couldn’t see me till Wed July 29th,at 8:00 am. When my husband and I further assessed the car after we got home we found that an explosion had occurred around her fuel tank, which was full at the time of the incident! The fuel tank expanded enough to completely rupture and detach her entire backseat! This incident was due to a recall replacing a valve on the fuel tank that was not conducted on the car from prior owners nor communication to the new owners (ME) upon my purchase of the vehicle. This could have been catastrophic to my daughter and anyone else in the vehicle had she kept driving the car and could have very easily been engulfed with flames and loss of life especially with a full tank of gas. The car has been towed to the local Kia dealership and leaked gas all in our driveway as it sat there. We are still awaiting response from Kia on our case it has been over 48 hours now and we have received no communication from them. KIA NEEDS TO DEEM THIS RECALL AS POSSIBLY FATAL AND ACT IMMEDIATELY TO SAVE LIVES!

SERVICE BRAKES
I am writing to formally file a complaint regarding my 2023 Kia K5 and the unacceptable experience I have had following a dangerous brake system failure. On Wednesday June 24th, while driving on Route 22 in New Jersey, my vehicle's brakes suddenly became extremely hard, making it incredibly difficult to stop. There were no lights on indicating an issue, neither any concerning sounds prior to this incident. I came dangerously close to being involved in an accident and was left extremely shaken. The situation was serious enough that my father had to come retrieve both me and my vehicle because I no longer felt safe driving it. I brought my vehicle to the Kia dealership on Friday, where I was informed that the repair would cost over $1,000. I find this extremely concerning given that Kia has previously recalled brake system components on other models for similar issues. While I understand my vehicle may not currently be included in that recall, a brake system failure on a 2023 vehicle is unacceptable and raises serious concerns about safety and product reliability. To make matters worse, I never even received a phone call from the service department to explain what was wrong with my vehicle or discuss the recommended repairs. Instead, I received nothing more than a text message with a link to a video. The first words I heard were, "Your brakes are really bad." For a customer who had just experienced a frightening brake failure that nearly resulted in an accident, I expected the courtesy of a direct phone call to explain the diagnosis, answer my questions, and discuss my options. Receiving only a video link felt impersonal and dismissive given the seriousness of the situation. After repeated back and forth with Kia corporate over the span of two weeks they determined that the repairs are on me, and I was offered nothing, even though this issue was of no fault of my own.

I DROPPED OFF MY CAR AT THE COVINA KIA DEALERSHIP EXPLAINING THE RECALL AND THE ISSUES I NOTICE SUCH AS A BULGE IN THE VERTICAL PORTION OF THE SEAT NEAR WHERE THE CALVES TOUCH. THE SEAT ALSO FEELS DIFFERENT FROM THE OTHER SIDE OF THE CAR. THEY SAID THERE IS A 3 BUSINESS DAY WAIT TO EVEN BE DIAGNOSED AND DID NOT ALLOW A RENTAL CAR. I HAD TO FIGURE OUT TRANSPORTATION. I HAVE NOT RECEIVED AN UPDATE ON THE STATUS VIA THE LINK OR FROM THE SERVICE DEPARTMENT AND IT IS THE END OF DAY 2. I TRIED CALLING BUT THERE IS AN AI MENU THAT I CANNOT GET PAST. I GOT NOTIFICATIONS TODAY FROM THE KIA APP THAT MY DOORS WERE UNLOCKED MULTIPLE TIMES OVER THE SPAN OF 30 MINUTES AND LEFT UNLOCKED AFTER THAT. I DONT SEE AN UPDATE ON THE SERVICE REPORT LINK AND I RECEIVED NO CALL. THE RECALL HAS ALSO BEEN WIPED FROM MY VIN WITH NO UPDATE.

SEATS, FUEL/PROPULSION SYSTEM
Shortly after refueling, I experienced a serious and sudden vehicle safety-related malfunction involving suspected fuel tank expansion. The event coincided with abnormal fuel behavior and an unexpected structural issue in the rear cabin area, where the rear seat assembly displaced upward without any passenger interaction or impact. The vehicle was inspected at Kia Archer, where I was informed it was unsafe to operate and required escalation to Kia corporate for review. I was advised the issue may involve a fuel system defect consistent with tank expansion potentially affecting surrounding structural or mounting components. Since that inspection, I have made repeated attempts to obtain clarification, safety guidance, and a technical explanation of the failure. These requests have not been meaningfully addressed. Communication from Kia corporate has been limited, delayed, or non-responsive. Instead of receiving a clear diagnostic explanation, repair plan, or safety directive, I was provided a buyback offer without supporting technical documentation, including no defect analysis, no engineering explanation, and no clear justification of valuation. I have also been presented with time-sensitive pressure to sign the buyback agreement despite the absence of disclosed safety findings or complete information regarding the defect. At this time: * The vehicle has been deemed unsafe by a dealership technician * A suspected fuel system defect involving tank expansion has been identified but not explained or resolved * There is concern of associated structural or mounting stress affecting interior components * Manufacturer communication has been insufficient and non-responsive following escalation * A buyback has been offered without transparent technical findings or defect disclosure * There is perceived pressure to accept terms without adequate time or information This was a huge safety risk to myself and any passengers I’ve had in my vehicle.

FUEL/PROPULSION SYSTEM
I am submitting this complaint regarding a serious safety defect involving my Kia K5 and the subsequent handling of this matter by Kia America. My vehicle was subject to a voluntary recall and was inspected by an authorized Kia dealership. During inspection, I was informed the vehicle has a defective fuel tank system that allowed air intrusion, resulting in abnormal pressure and structural impact to the vehicle. I was further advised by dealership personnel this condition created a risk the vehicle could catch fire or explode while being operated. As a result, the dealership retained possession of my vehicle and deemed it unsafe to drive. I have been without use of my vehicle and Kia has provided a rental car. For approximately eighteen (18) months prior to this discovery, I unknowingly operated this vehicle under these conditions. During that time, my minor child was a regular passenger in the rear seating area of the vehicle. My child has experienced ongoing neurological symptoms, including persistent headaches over a period of several months, which have required medical evaluation. While no definitive cause has yet been determined, the possibility of prolonged exposure to fuel vapors within the vehicle is a serious concern. In addition to the safety risk, I have incurred substantial financial losses, including: Monthly payments totaling approximately $10,170 Down payment $1,000 Maintenence $1,800 Insurance costs totaling approximately $7,500 Despite the severity of the defect and the fact the vehicle cannot be repaired or returned to me, Kia America has only offered resolution options that: Do not fully reimburse my financial losses In some cases require me to pay out-of-pocket to resolve the issue Do not account for the significant safety risks involved Furthermore, Kia America has imposed a deadline for acceptance of these inadequate offers and has stated that if I do not accept, they will: Discontinue providing a rental vehicle Return the unsafe vehicle to me
