FUEL/PROPULSION SYSTEM
I took my 2021 KIA K5 to the dealership in March of 2025 for an oil change. While I was there, a diagnostic test was conducted to determine if my vehicle was affected by a damaged check valve. Therefore, the car could have caught on fire while it was being driven. I was given a rental car while my vehicle was supposed to be fixed. KIA deemed my 2021 K5 to be a hazard to the road. In June of 2025, KIA offered to pay my loan balance off and give me less than $250 for the "down payment." Please note when I purchased the KIA K5 in 2021, I traded my 2018 KIA Optima. Now, in June of 2026, KIA in offering me $13,200 for my KIA K5. I have until June 29, 2026, to accept the offer. The balance on my loan will come out of that so, I will receive approximately $7000 for a car I will pay a total of $44,000 for. I never once stopped making my monthly payment and my car has been deemed a hazard for the road since March of 2025. For years, I drove a vehicle that could have potentially caused a death or injury.

Vehicle was shaking really bad. Inner tie rod was completely worn out and rusted around 32,000-37,000 miles. 04/23/2026 Ricart Automotive Group, Car purchased [XXX]. Issues since purchasing vehicle 1. AWD Electronic Motor Failed 02/28/2024 2,715 miles. 2. Chrome Side and Rear Pieces coming off 05/12/2026 22,019 miles. 3. Fuel Tank ECM Recall 08/05/2025 24,474 miles. 4. Passenger side mirror replaced 09/19/2025 26,180 miles 5. Fuel Tank Band Inspection 02/09/2026 34,167 miles 6. Passenger Side inner tie rod 04/23/2026 37,860 miles I have spoken with Theresa D. from Kia Customer Care (520)274-1627 requesting the vehicle be replaced or bought back, but due to Ohio's Law covering only the 1st year or 18,000 miles and Kia not issuing the recall until after these deadlines they were unwilling to work with me to replace or buy back, but instead offered me a 1,600.00 settlement. This seems unfair knowing that the issues above 3 and 6 had a recall for Kia K5 Models 2021–2024. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

POWER TRAIN
On startup, the engine took about an extra second to fire. The starter cranked noticeably longer than normal before the car turned on. Shortly after, I pulled out and turned onto a street. When I pressed the accelerator, there was no response at all. No rev increase and no acceleration. The car would not pick up speed. I switched to manual shift mode to try to force a gear change. When I changed gears, it took a couple of seconds to respond each time, much slower than normal. I managed to coast/limp to a nearby gas station. I shut the car off and restarted it, and the problem cleared completely. The car has driven normally since.

Premature Leaking Evaporator Core – 2021 Kia K5 I am submitting this complaint regarding a leaking evaporator core in my 2021 Kia K5. The evaporator core failed at approximately 59,600 miles, causing the air conditioning system to stop cooling properly. The vehicle was diagnosed by a repair facility, which determined that the evaporator core was leaking refrigerant and required replacement. An evaporator core is a major HVAC component that should not fail at such low mileage under normal operating conditions. This failure affects the vehicle’s ability to properly dehumidify and defrost the windshield, which can reduce visibility and create a potential safety hazard during rain, high humidity, or cold weather conditions. I have maintained the vehicle as recommended and believe this component failed prematurely. Due to the extensive labor required to replace the evaporator core, the repair cost is significant. I am requesting that NHTSA review this issue to determine whether there is a pattern of premature evaporator core failures in 2021 Kia K5 vehicles and whether an investigation is warranted. Vehicle Information: * Year: 2021 * Make: Kia * Model: K5 * Mileage at Failure: 59,600 miles * Failure: Leaking evaporator core causing refrigerant loss and loss of air conditioning performance Thank you for your consideration.

FUEL/PROPULSION SYSTEM, UNKNOWN OR OTHER
In XXX 2026, I brought my 2022 Kia K5 GT-Line (VIN: [XXX] ) to Jim Click Kia in Tucson, AZ for routine maintenance. Fuel system testing revealed my vehicle failed inspection due to an active federal recall affecting the fuel tank/fuel valve system. Kia America confirmed the recall defect caused cascading damage to additional components, rendering the vehicle completely unrepairable and unsafe to drive. My safety was put at risk because the vehicle cannot be operated and Kia has confirmed no repair is possible. I have been without my vehicle for over two months. Kia America has proposed a buyback at $10,550 (KBB value), which does not reimburse me for the approximately $35,000+ I paid into this vehicle. I have formally requested full reimbursement under 49 U.S.C. § 30120 and the Magnuson-Moss Warranty Act, which Kia has declined. I am currently in a rental vehicle paid by Kia, which they have threatened to terminate on June 9, 2026 if I do not accept their offer.

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.

ELECTRICAL SYSTEM
I am writing to formally complain about the ongoing issues with my vehicle, specifically the repeated failure of the air conditioning system and the excessive number of recalls that have caused major inconvenience and lost work time. The air conditioning unit in my vehicle has failed three separate times. Each time, I was told the fan motor needed to be replaced, and the motor has now been replaced three times. After each repair, the system works temporarily before failing again. I have now been informed that the issue may actually be electrical in nature, which raises concerns that the original problem was never properly diagnosed or repaired. In addition to the air conditioning problems, my vehicle has been subject to multiple recalls requiring repeated trips for repairs. These ongoing issues have forced me to miss work several times, causing financial hardship, stress, and a loss of confidence in the reliability and safety of my vehicle. At this point, I am requesting the following: A full inspection and proper diagnosis of the electrical system related to the air conditioning failure. A permanent repair solution rather than temporary fixes. Reimbursement or compensation for repeated repair visits, missed work time, and inconvenience caused by these recurring issues. A review of my vehicle’s repair history to determine whether additional corrective action is appropriate. I have made every effort to address these issues through the proper service channels, but the recurring failures continue. I expect this matter to be taken seriously and resolved promptly. Please contact me as soon as possible regarding the next steps to resolve this issue. Sincerely,

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.

My sunroof glass spontaneously shattered causing glass to be everywhere inside my car while I was driving. It scared me and now my car is undrivable until the glass is repaired. I see many thread online of other Kia K5 owners have experienced the same issue. My initial thought was that my tire popped so I tried to pull off to the side of the road but cars were just trying to get around me. I opened up my sunroof because it did sound like something popped and there was a big hole in my sunroof. I immediately closed it and drove home.

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

There is a hard shift after the car has been parked. Bought the car with 6 miles on it, now has 35,000. This issue is not new, we have had it into 2 different dealerships, and neither "were able to duplicate the issue". It is increasingly getting worse so it will be going back to the shop yet again.

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
