The contact owns a 2022 Kia K5. The contact received notification of NHTSA Campaign Number: 25V794000 (FUEL SYSTEM, GASOLINE); however, the part to do the recall repair was unavailable. The local dealer was contacted, and it was confirmed that the part was not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The contact experienced the failure, causing the check engine warning light to remain illuminated, and the vehicle hesitated while accelerating. The vehicle was taken to the local mechanic, who diagnosed the vehicle and determined that the check valve was faulty and needed to be replaced. The vehicle was not repaired. Additionally, the contact stated that while the AC was activated, one vent was blowing hot air while the other vent was blowing cold air. No further information was available. The failure mileage was 103,000.
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.
Engine failed for literally no reason and started smoking and Lia won’t stand by warranty either
My vehicle is subject to an unrepaired safety recall involving the fuel system. According to the manufacturer’s recall notice, a damaged check valve may allow air to enter the fuel tank, causing the tank to expand and contact hot exhaust components. This can melt the fuel tank, cause fuel leakage, and increase the risk of a vehicle fire. This vehicle has experienced multiple fuel-system-related recalls, and this recall is currently listed as incomplete with no remedy available. The manufacturer has not provided a repair timeline, and owner notification and repair availability are delayed. I am concerned for my safety and the safety of my passengers because I am required to continue driving a vehicle that the manufacturer acknowledges poses a fire risk and cannot currently be repaired.
