Consumer Description

For the past 16 months I have been experiencing a fuel odor in my vehicle cabin while idling or when in slow moving traffic. Knowing this likely is due to a fuel leak, I have taken it to the dealership 6 times to find the leak and remedy it. The dealership always finds something to repair/replace under warranty, however, the fuel smell persists. Over the past 16 months, this has increased in how strong the smell is and how often I am smelling it. It started out as only smelling fuel once a week or so. Now the smell is there during ever drive. It seems as though if my tank of 7/8 or above full, it does not smell for some reason. Upon searching online, many other K5 owners are experiencing the same exact issue and the dealership has been unable to resolve this. The vehicle has had 3 seperate recalls for fuel issues and I believe another is necessary regarding this because the recalls has not fixed the fuel leak I and many others are experiencing. Kia is doing the bare minimum to resolve this and my children are breathing fuel fumes consequently. Please note, not all my repair invoices are attached. I do not have access to all of them at this time
