FUEL/PROPULSION SYSTEM, ENGINE, ELECTRICAL SYSTEM
Just minutes before entering the highway, my son and I heard a very loud popping sound that startled us, like something large hit the car or a tire exploded. I immediately pulled into a gas station checked the exterior & all 4 tires, but everything appeared intact. Shortly after, while driving on hwy during morning rush hour at 65–70 mph in the far-left lane, the check engine light illuminated & almost immediately the car lost all engine power. My speed dropped quickly with cars behind me traveling at high speeds. I had to activate hazard lights & cut across 4 lanes of traffic to the shoulder, putting myself, my child passenger, & others at serious risk of a multi-car collision. While waiting for help, I plugged in my FIXD OBD-II reader later looking over diagnostics read code P0451 – EVAP System Pressure Sensor. 8 hours after car was towed & had been parked at my home & still not starting I researched the code to learn what that means & the possible cause for & found it is all emission related issues varying in reasons as simple as a gas cap replacement. Nothing of any engine failure while driving risking the lives of drivers & others so before sending my car to a mechanic, I went and checked the gas cap in case just a simple emissions type fix that is where I observed fuel still bubbling out of the tank have photos, my daughter, & sister, as witnesses. The next day car was towed to Kia Mall of Georgia on June 26, 2025. As of August 20, 2025, the dealership has confirmed the fuel tank expanded as of now there is no resolution from Kia for fixing once this happens can likely shift car frame & could be declared totaled. Component/system failed: Fuel tank/EVAP system (pressure failure). Vehicle is available for inspection at Kia Mall of Georgia. Safety risk:Complete engine shutdown at highway speeds with child passenger on board; risk of multi-car, high-speed crash. Fuel bubbling/spitting increased fire hazard. not a recall only emissions campaign needs to change

FUEL/PROPULSION SYSTEM
The fuel tank in my 2023 Kia K5 LXS expanded and bent the subframe. This is a known problem with K5's with the 1.5L turbo engine. Kia had an emissions campaign for this problem affecting 2021 to 2024 models. My VIN isn't in that campaign, but it had the same problem. Given the fuel tank expansion and bent subframe, my car is no longer safe to drive and has been sitting at the dealership. I was told that with the fuel tank expansion a plate could pop open and create a fire or explosion. This also caused a significant loss of power, making the car untenable to operate. Kia's Techline reviewed the findings from the dealership service department (Campbell Kia Missoula), but closed the case without offering a repair and escalated it to another department (Consumer Affairs?), where it remains unresolved after two weeks. Kia is failing to resolve the issue in the form of either a repair or a buyback and keeps dragging the case out with virtually no contact or updates. Please help. This needs resolved ASAP.

ENGINE, FUEL/PROPULSION SYSTEM
Car stalls out without warning. The electronics (radio, dash, lights, etc...) all are still functional, the engine light comes on while the car is still "on" with the engine stalled out. I pulled over, put the car in park, turned it off, and then restarted the car without issue. After restarting the car, the check engine light is not longer on. This first occurred once about a year or two after i bought the car while on the freeway (2023). The second time I was on a dirt road outside of town (March 2025). The third time I was accelerating through an intersection while taking a left turn, after being stopped at the green light waiting for a time to turn (August 2025). My car stalled out in the middle of the intersection, but I was lucky enough to have gained enough momentum to roll out of the way of oncoming vehicles. The most recent time this occurred, the car had trouble turning over, but was able to after a few tries. I took it into my kia dealership and they told me to replace the battery as it was testing "low". I bought a battery from autozone and replaced it as instructed. However I have never had any issues otherwise and the battery test autozone performed on my old battery said the old battery was still "good". This was recent and the problem is rare so i have not confirmed if this is a fix, however it is a dangerous fault that does not seem to be resolved.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, FORWARD COLLISION AVOIDANCE: WARNINGS, LANE DEPARTURE: BLIND SPOT DETECTION
After getting my rearview mirror, repaired by the Kia dealership when I break when I came to a stop, my car started flashing forward, collision warnings, and Blindspot assist warnings and activated the emergency parking break ticket to the Kia dealership they saw the safety issues in in diagnostics and a history of it They said they won't replace anything unless it happens in the dealership's care gave the car back to me and less than five minutes after leaving the same issue occurred. They've currently had my car two weeks and have no update on what's going on was almost in an accident because of this issue after getting it back from the dealership. I also have a recording of the dealership stash. They won't do anything about it unless it happens in their care. With them, knowing it's a safety issue.

BACK OVER PREVENTION: REARVIEW SYSTEM BRAKING, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
The reverse braking feature registers cross traffic or movement that is not near the back of the vehicle. This cause the braking system to engage. I was doing a U turn on 4 lane main street with a center divider. I didnt fully clear the turn leaving me to reverse to complete to turn. When i put the car in reverse, the sensors picked up movement across the street, engaging the brakes and leaving me stuck in the middle of the road with oncoming traffic coming straight at me. It would not disengage when I tried accelerating and I had to quickly throw my car into drive and pull into a driveway, that was luckily there, just to avoid being T-boned by oncoming traffic. This is not the first occurance as it happens often in parking lots locking my brakes due to any movement from behind. There is a manual feature in the dashboard to turn it off but it automatically resets every time the car is turned off, requiring you to have to manually disengage the feature everytime and you cannot disengage while the brakes are locked.i took it to the dealers but they said since it is a "feature" it is not considered a safety issue since there is an option to disengage even though it has to be reset during every use. They could not help or remedy the issue and instructed me to file a complaint with Kia manufactures since they are only the Kia dealer.

UNKNOWN OR OTHER, ELECTRICAL SYSTEM, VISIBILITY/WIPER
Blower motor failure, available for inspection upon request. The failure occurred while driving in muggy conditions, resulting in rapid fogging of the windshield and front side windows. With no functioning airflow, the vehicle’s defrost/defog system was inoperable, and visibility through the windshield became significantly impaired. This required me to reduce speed and open windows in inclement weather to maintain a minimal view of the road, creating additional distraction and exposure to hazardous conditions. The blower motor produces no airflow at any fan speed setting. Failure was confirmed during inspection. No warning lights, messages, or other indicators appeared before, during, or after the failure. This is not an isolated incident. A brief search reveals numerous reports from Kia K5 owners describing the same sudden blower motor failure, indicating a likely systemic defect in the HVAC system design. Kia has not issued a recall, technical service bulletin, or other remedy despite repeated reports from vehicle owners. Kia’s continued inaction in the face of widespread, well-documented blower motor failures represents a disregard for both driver safety and basic manufacturing responsibility. Numerous Kia K5 owners have already been victimized by this defect, and doubtlessly many more will be as long as these vehicles remain on the road unrepaired. The loss of climate control directly compromises a driver’s ability to maintain a clear windshield, safely see the road, and operate the vehicle in adverse weather. These are not “comfort” issues, they are safety-critical failures. By ignoring the mounting evidence and leaving affected vehicles on the road without a remedy, Kia is willfully allowing a known hazard to persist, exposing thousands of drivers and passengers to unnecessary and avoidable risk.

AIR BAGS
Side Curtain and Seat Side Airbags. Unavailable for inspection as Avis Rental Company cleaned the vehicle, removed airbags, and sold at auction as salvage. Side curtain airbags trapped me in the vehicle, and shrapnel from seat side airbag impaled/injured my arm. Combination of Side Curtain and Seat Side airbags, and seat belt, resulted in catastrophic shoulder injuries. Additionally, the gases and powder substance from the airbag deployment caused a severe asthma attack. I was told that the entire interior was covered in a powder substance. Note: It appears that Avis Rental Company rented this vehicle out in violation of Federal Law (FIXING AMERICA'S SURFACE TRANSPORTATION ACT - Public Law 114-94 114th Congress - SEC. 24109. <<NOTE: Raechel and Jacqueline Houck Safe Rental Car Act of 2015.>> RENTAL CAR SAFETY.) as the recall is still showing as unresolved. I had also contact Kia Corporate and Kia Maui to inquire as to whether they had record of the recall being resolved and neither did.

FUEL/PROPULSION SYSTEM, UNKNOWN OR OTHER
The fuel tank expanded causing the vehicle to become immobile. The car is sitting at a dealership after I declined to sign Kia's buyback so yes it available for inspection. As for my safety and other the fact a fuel tank is swelling under where people would sit and it is highly flammable/ combustible is kind of alarming to me. Yes, there are plenty of people having the same problems. The dealership has sent pictures and videos into Kia for their engineers to look over. The day before the car became immobile it was getting horrible gas mileage. There was no other things that happened no lights on the dash.

FUEL SYSTEM, GASOLINE
The contact's daughter owns a 2021 Kia K5. The contact stated that while the contact’s son-in-law was driving, the fuel level indicator failed to function as intended.
