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.

A recall from Kia a damage check valve and a fuel tank issue. I have called the manufacture Kia company and they have no result, I have called for over a month now and haven’t had my car for a month and an half now, still waiting for a results or a solution for the Kia K5 GT Line. I have called my case manager as well, every time I call it goes straight to voicemail. I am looking to contact anyone from higher up to help me find a solution for my car.

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.

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

On April 8th my car was taken to the dealership for repair on a hose. When the dealership did a diagnostic on the vehicle it had 4 safety recalls. And my car had a major recall the fuel pump on my car expanded and it was very dangerous for me and my kids to drive the vehicle per Kia they say it could have blown up. My car can not be released to me and I’m without a vehicle. On the night of April 7th my Kia k5 ran hot without any warning lamps and the thermostat radar in the car did not indicate hot at all!

I am writing to formally report that the manufacturer of my vehicle is refusing to repair a safety issue covered under an active recall. My vehicle is subject to Manufacturer Recall Number SC356. I brought my vehicle to an authorized dealership for inspection and repair as instructed.However, after evaluating the vehicle, the manufacturer/dealer informed me that the issue cannot be repaired. I am concerned because this situation leaves me without a proper remedy for a known safety defect. I understand that under federal law, manufacturers are required to provide an effective repair, replacement, or refund for safety recalls. At this time, I have not received a satisfactory resolution that ensures my safety or complies with recall obligations. I respectfully request that NHTSA review this case and provide guidance or take appropriate action to ensure the manufacturer fulfills its responsibilities.
