Open the full vehicle complaint log (all categories)In October 23, 2025 I started to notice a fuel smell while I was driving the vehicle. The smell of fuel seemed more strong while I had the air conditioning running.I would shut off the AC and put the windows down. There was no leaks of fuel on the ground or close to the motor. No check engine light or messages was displayed on dash at anytime. My concern was that I’m constantly driving my small children in car seats to and from school, sports, and appointments the smell the fumes will cause headaches or worse car will catch fire were we would need to make a fast exit out the vehicle. So I made an appointment with Kia of Stockton and they scheduled me for 10/29/26 at 9:30am. Kia first diagnosis was undetermined and charged me another $315 just to keep diagnosing on top of there first fee of $315. Kia discovered after removing the foam that protects the fuel rail the leak was coming from fuel injectors and fuel rail. Fuel injector leaking where injector inserts into rail. Repair was needed due to failure of fuel rail housing not sealing properly. Kia also replaced associated components with the fuel rail clips, bolts, flanges, high pressure sensor, foam, and injector wire harness. According to Kia there tech found short in the injector harness.
Fuel gauge does not provide accurate representation of fuel amount. The car will read empty with 100 miles .
Vehicle mileage was about 1,750. Check engine light came on immediately after starting the engine and vehicle had a slight vibration. Drove to dealer and vehicle started shaking badly while accelerating and had slight burning smell inside the cab. Was told #6 cylinder was miss firing and fuel injector needed to be replaced. Dealer has fixed the issue and seems to be ok as of now.
