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!

VISIBILITY/WIPER, ELECTRICAL SYSTEM
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

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.

UNKNOWN OR OTHER
I am contacting Kia America Consumer Affairs to formally request a Goodwill Warranty Exception for the total failure of the factory infotainment and radio system in my 2024 Kia K5 LXS. The unit has completely lost Bluetooth and Apple CarPlay functionality. A certified technician has diagnosed the issue as an internal radio hardware failure requiring a complete replacement, quoted at an exorbitant out-of-pocket cost. While my vehicle has surpassed the standard 3-year/36,000-mile radio warranty threshold, this premature electronic failure is a documented, systemic manufacturing defect rather than normal wear and tear. I have fully exhausted all personal troubleshooting measures—including performing hard pinhole resets, deep system restarts via battery disconnection, clear-pairing device profiles, and verifying device firmware. The underlying hardware remains completely non-responsive. Furthermore, Kia America is explicitly aware of this systemic defect in this generation of head units, as evidenced by the publication of Technical Service Bulletin SA582 ("AVN 5.0 Wide Non-Responsive Radio Icon"), which explicitly acknowledges software and hardware stability failures in 2023–2024 infotainment units. Because the failure of this head unit completely eliminates hands-free voice operations, emergency communications, and navigation systems, it introduces an immediate driver distraction and safety hazard on public roads. As a loyal Kia owner who purchased this vehicle expecting modern reliability, I am asking Kia Corporate to review this case, acknowledge the documented history of this defect, and issue a Goodwill Exception to cover the replacement cost of this unit at a certified local dealership. I look forward to your prompt response and the assignment of a regional case manager to resolve this matter.

FUEL/PROPULSION SYSTEM
My car is losing power upon acceleration causing a loss of power upon take off upon taking off and when gears are shifting. Told by dealer it is a problem with fuel injection. Replaced several coil packs and spark plugs on my own. Dealer repair shop had my car for 4 days for the fuel talk and valve issues and did not repair anything. Losing power when I drive in traffic and on highway is a huge safety issue causing loss of power when at highway speeds. I plugged in a code reader bought by myself which is telling me it’s coil packs. We have replaced several with no luck. There is a smell of fuel and with all the other fuel system recalls and after reading other complaints on this site that sounds similar, I fear this is a safety issue with the vehicle. They checked my fuel tank and valve but didn’t replace either. I believe this is related to all the other fuel system recalls and should be repaired free of charge by dealer as a dysfunctional fuel problem as nothing we’ve done to repair with the code reader has fixed this issue. I fear a loss of power of fire caused by the mounting fuel system issues of these issues have caused the issue I’m having. Please look into this as several other complaints I’ve read online by owners are having same issue. My car only has 68,000 miles. I’m in fear of serious injury as a cause of these issues. Also concerned dealer had my car 4 days and DID. NOT repair or replace fuel tank or fuel valve, why did they have my car this long and DID NOT REPAIR the recall that the vehicle was there and the appointment was scheduled for such? I really have a fear there is an accident in my vehicle travels caused by mounting fuel issue recalls and problems. Please please look into this and help with these mounting fuel system issues before serious injury or death!

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, FORWARD COLLISION AVOIDANCE: WARNINGS, LANE DEPARTURE: ASSIST
Submitted by [XXX], Authorized Representative for the owner. The vehicle has a physical defect in the ADAS forward-facing camera bracket caused by a dealer-concealed repair using industrial silicone adhesive. The bracket is now visibly sagging, causing misalignment that leads to intermittent Automatic Emergency Braking (AEB) failure. Critically, the vehicle’s computer does NOT illuminate a warning light for this physical displacement ('silent failure'), posing a severe crash risk. An undisclosed aftermarket GPS tracker was also found installed, which is pending contract review. A third-party inspection report titled 'Repurchase Inspection (Silicon at Rearview Mirror)' confirms the non-OEM adhesive and physical sag. The dealer has refused to provide a safe replacement vehicle. This defect stems from a non-OEM repair performed prior to sale.

FUEL SYSTEM, GASOLINE
The contact owns a 2022 Kia K5. The contact stated that while attempting to reverse her vehicle and then shifting the gear shift into drive, the contact noticed her check engine warning illuminated, and she heard an abnormal noise coming from the front of the vehicle. The contact then parked the vehicle, went into the dealer, and let them know about the failure, but they offered no assistance. The vehicle was initially taken to the dealer, where NHTSA Campaign Number: 25V794000 (FUEL SYSTEM, GASOLINE) was completed. It was after the recall was completed that it was discovered that the check engine light illuminated, and the vehicle was not driving properly. The dealer took the vehicle back and provided a loaner. The contact mentioned that the engine was replaced, and then a catalytic converter was replaced. Most recently, the fuel oxygen sensor was discovered to be melted. The vehicle was repaired; however, the failure persisted. The manufacturer was notified of the failure and informed that the recall was complete with no other assistance offered. The failure mileage was 91,000.

WHEELS
While my 2025 Kia K5 was parked in the driveway, the front driver-side original-equipment Pirelli P Zero All Season tire suddenly blew out. I had just parked and walked inside when we heard a loud pop. There was no impact, no curb strike, and no driving event - the vehicle was stationary when the tire failed. The vehicle had approximately 16,500 miles. This is part of an apparent pattern: my son purchased an identical 2025 Kia K5 on the same day from the same dealer. At about 22,000 miles, his front driver-side tire developed a sidewall bulge, and all four of his original-equipment Pirelli tires show rapid, uneven wear. Two identical vehicles, bought together, both experienced failure of the same tire position (front driver-side) - his bulging, mine blowing out - which strongly suggests a defect in the original-equipment tires and/or a vehicle alignment/suspension condition causing abnormal wear and failure. No crash, injury, or fire resulted because the vehicle was parked. However, a sudden tire failure of this kind at highway speed would create a serious risk of a blowout, loss of control, and crash. The failed tire is available for inspection upon request. I am filing this complaint to document the failure and the pattern across two identical vehicles.

SUSPENSION, WHEELS
At approximately 22,000 miles, all four original-equipment Pirelli P Zero All Season tires on my 2025 Kia K5 are showing rapid and uneven tread wear that is far beyond normal for the mileage. Last week I discovered that the front driver-side tire has also developed a visible bulge/bubble in the sidewall, which indicates internal structural failure and an imminent risk of sudden blowout. There were no warning lights, no impact event, and no inflation problem before the bulge appeared. This is especially concerning because my father purchased an identical 2025 Kia K5 on the same day from the same dealer. His vehicle has significantly fewer miles, yet his front driver-side tire suddenly blew out while parked in his driveway. The fact that two identical vehicles, purchased together, both experienced failure of the same tire position points to a possible defect in the original-equipment tires and/or a vehicle alignment/suspension condition causing abnormal wear. No crash or injury has occurred yet, but a sidewall bulge at highway speed creates a serious risk of a blowout, loss of control, and crash. The vehicle and the affected tire are available for inspection upon request. The tires have not yet been inspected by a dealer or independent shop. I am filing this complaint to document the safety concern and the apparent pattern across two identical vehicles.
