ENGINE
At 2500 miles when checking my oil I discovered flakes of metal on the dipstick. I immediately changed the oil and in doing so found a massive amounts of metal in the filter housing. I took it to the dealer along with pictures and told them on startup the engine was noisy and sounded like it was low on oil, noisy on acceleration and would exabit an engine knock at times when hot. They didn't investigate it at all. Being an auto tech all my life, I know that metal flakes are a sigh of a damaged bearing and by the sound, a conrod bearing. I'm afraid to take it anywhere other than local commutes. This sounds like the same thing as the K4 Tuscan issue in my professional opinion.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER, VISIBILITY/WIPER
Kia dealership has confirmed that the components of the vehicle's multi-fuse (located under the hood) for the AC/HVAC system have started to burn and are melting part of the fuse panel due to excessive current draw and excessive heat. Due to this, the vehicle's HVAC (both heat and a/c) does not function. A vehicle's HVAC functions help to: 1) Defrost/defog vehicle's windows during rainy and humid days, 2) maintains a vehicle's air quality, 3) cools the vehicle's interior on hot and humid days, 4) assists in preventing mold and bacteria growth via dehumidification, 5) assists in keeping the cabin cool and dry to prevent driver fatigue and promote driver focus. Other than the inoperability of the HVAC system, no other signs or symptoms were present prior to the issue. I initially though this issue would be covered under Kia's HVAC Blower technical bulletin/warranty (WTY037) however the dealership has advised that the WTY037 only applies if the fuse is blown, not melted. This slight difference in melting vs. blowing should be an issue as the effect of the issue is the same, but components melting seems to be slightly more serious, but is not covered. Also, melting components, to me, could lead to fire hazards.

FUEL SYSTEM, GASOLINE, FUEL SYSTEM, GASOLINE:STORAGE:TANK ASSEMBLY
The contact owns a 2022 Kia K5. The contact stated that while driving at 43 MPH, the vehicle made an abnormally loud booming sound. The contact's daughter, who was occupying a rear seat, screamed out because the rear seats had suddenly risen. The contact pulled over to the side of the road and inspected the vehicle. The check engine and the low fuel warning lights were illuminated. The contact's wife met the contact and picked up the children. The contact stated that upon resuming driving, the vehicle was jerking violently, and the fuel gauge level lowered significantly. The vehicle was taken to an independent mechanic, where it was diagnosed with an EVAP system failure. The vehicle was driven to the residence. The vehicle was then towed to the dealer, where it was diagnosed, and determined that the fuel tank had expanded. The vehicle was not repaired. The manufacturer was notified of the failure and offered to repurchase the vehicle. The failure mileage was approximately 85,000.

UNKNOWN OR OTHER, FUEL/PROPULSION SYSTEM
HVAC is not working at all, not even blowing hot air. I've been told it could be a wiring issue or have to change my blower and resistor. KIA has told me they could not help because my car is over the 60,000 mile warranty. However, my car is 70,000 miles and about 4 years old. It has had other recall issues and just trying to be helped.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER
At the beginning at the year I had to change my starter because my car would leave me stranded on the street, at a stop light or any time my car would stop. I was once in the car with my little brother and in the middle of the street it would not start again and left us stranded. Others around me had to help me push the car to the side of the road that way I wouldn't be rear ended. Now, I'm having other issues such as HVAC were my cars AC does not turn on. It doesn't even blow hot air. Some mechanics have told me it's probably my blower and resistor and other that it's a wiring issue. My car is only 4 years old and should not be having so many issues. I have tried reaching out to Kia but always get sent to voicemail or have told I would be charged for it to just be seen. If anyone could help me with my car that would be greatly appreciated.

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.
