2022 Kia K5

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.

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.

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.
