Hi guys, ive only had the ksx-s awd for a few months now, but occasionally with the fan on low during driving, i get a really bad rotten egg smell that enters the car. Im not sure if its coming in via the vents, or from under the car or something. It doesnt seem to matter if its on heat, fan, or air con? Ive read somewhere that a rotten egg smell can indicate the that the catalyic converter may be buggered. Any one else experience this, or have any suggestons?
