NHTSA investigations into the 2023 KIA K5

An investigation is the step before a recall: the agency has seen enough complaints to look into a pattern itself. An open one means it thinks something may be wrong and nothing has been fixed yet.

Loss of Motive Power

The National Highway Traffic Safety Administration (NHTSA) received a letter dated July 13, 2022, petitioning the Agency to initiate a safety defect investigation into loss of motive power allegations attributed to oil drain pan assembly failures on certain Hyundai Motor America, Inc. and Kia America, Inc. vehicles spanning Model Years (MY) 2005-2021. The Petitioners cited examples of complaints indicating that the subject vehicles were experiencing rapid loss of engine oil due to oil drain plug back outs, resulting in loss of motive power and/or catastrophic engine damage.

Recalls on the 2023 KIA K5

A complaint is one owner's allegation. A recall is the point at which the manufacturer or a regulator agreed the defect is real and dangerous enough to fix for free — however old the car is.

United States — NHTSA

25V794000

FUEL SYSTEM, GASOLINE

Kia America, Inc. (Kia) is recalling certain 2021-2024 K5 vehicles. A damaged check valve can allow air to enter the fuel tank, causing it to expand and contact hot exhaust components, melting the tank.

Risk: A melted fuel tank can leak, increasing the risk of a fire.

25V493000

STRUCTURE:BODY:ROOF AND PILLARS

Kia America, Inc. (Kia) is recalling certain 2023-2025 K5 vehicles. The left and right rear window trim pieces may loosen and detach.

Risk: Detached trim pieces can create a road hazard for other vehicles, increasing the risk of a crash.

23V149000

AIR BAGS:SIDE/WINDOW:CURTAIN

Kia America, Inc. (Kia) is recalling certain 2021-2023 K5 vehicles. The side curtain air bags may have been installed incorrectly, causing them not to deploy properly in the event of a crash.

Risk: Air bags that do not deploy as intended can increase the risk of injury in a crash.

22V760000

POWER TRAIN:AUTOMATIC TRANSMISSION

Kia Motors, Inc. (Kia) is recalling certain 2021-2022 Sorento and 2021-2023 K5 vehicles. The vehicle's "fail-safe" limited-mobility drive mode may be impaired, when prompted by a transmission oil pump malfunction, which can result in a complete loss of drive power.

Risk: Loss of drive power increases the risk of a crash.

Canada — Transport Canada

Canada runs its own recall programme, and its campaigns do not always mirror the American ones.

Recall 2025638 2,737 units in Canada

Fuel System

Issue: On certain vehicles, the check valve for the purge control system could wear and cause the fuel tank to expand. As a result, the fuel tank could contact hot components and fuel could leak. Note: This recall only affects certain vehicles equipped with a 1.6 L turbocharged engine. Safety Risk: A fuel leak can create the risk of a fire. Corrective Actions: Kia will notify owners by mail and advise you to take your vehicle to a dealership to replace the check valve and update the electronic control unit (ECU) software. The dealer will also inspect and, if necessary, replace the fuel tank.

Recall 2025398 1,032 units in Canada

Structure

Issue: On certain vehicles, the exterior trims on the C-pillars may not be properly attached. As a result, the trim(s) could loosen and separate from the vehicle. Safety Risk: Parts that detach from the vehicle could create a road hazard for others and increase the risk of a crash. Corrective Actions: Kia will notify owners by mail and advise you to take your vehicle to a dealership to replace the exterior C-pillar trims.

Recall 2023124 2,593 units in Canada

Airbag

Issue: On certain vehicles, the side curtain airbag(s) may not have been installed correctly. As a result, the side curtain airbag(s) may not inflate properly in a crash. Safety Risk: A side curtain airbag that doesn't work properly could increase the risk of injury in a crash. Corrective Actions: Kia will notify owners by mail and instruct you to take your vehicle to a dealership to inspect the installation of the side curtain airbags, and reinstall them correctly if necessary.

Recall 2022580 9,039 units in Canada

Powertrain

Issue: On certain vehicles, a fault in the transmission oil pump can cause the vehicle to enter "fail-safe mode". When this happens, a programming error can cause a sudden loss of power to the wheels after 20-30 seconds. Note: This recall only affects vehicles equipped with a 2.5 L turbo gasoline (T-GDI) engine and an 8-speed dual-clutch transmission (DCT). Safety Risk: A sudden loss of power to the wheels could increase the risk of a crash. Corrective Actions: Kia will notify owners by mail and instruct you to take your vehicle to a dealership to inspect and, if necessary, replace the transmission. The dealer will also update the transmission control unit software.

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

SEATS

In June 2025, while driving my 2023 Kia K5 (VIN: [XXX] ) at highway speeds on [XXX], the fuel tank suddenly imploded. A loud bang caused the rear seats to lift, startling me and my passengers. The car lost power, and braking too hard risked leaving us stranded in fast-moving traffic. I narrowly avoided a crash while trying to maneuver us to safety. This vehicle was previously recalled by Kia in April 2024 for a fuel tank defect affecting ~236,000 vehicles. I took it to Gunther Kia in Davie, FL for inspection, and they claimed it was fixed. In March 2025, I returned to Hollywood Kia because of popping sounds and a check engine light. They diagnosed and “repaired” a purge control valve but failed to address the underlying defect. Despite these repairs, the catastrophic failure still occurred. The vehicle is now completely inoperable and irreparable. Kia later offered to buy back the vehicle but failed to respond to over 200 calls and dozens of emails from me, allowing their offer to expire without explanation. This left me paying for a vehicle I can no longer use. This defect poses a serious danger not only to me and my passengers but also to thousands of other K5 owners nationwide. I urge NHTSA to investigate Kia’s recall handling and ensure affected vehicles are properly repaired to prevent injury or death.

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.

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.

Eastvale, CA

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.

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!

ENGINE

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

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!

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

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.

SEATS

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
