Have had car ~18 months, bought new in Aug. 2014. All of a sudden a couple of months ago, had rotten egg smell in the car whenever heater or rear window defroster were turned on. Assumed it was perhaps a dead animal or worst case scenario, catalytic converter (which should never be the case) so brought to place of purchase for investigation. They told me it was a lead pipe that was filled with a plastic bag and dry leaves, etc. so they cleaned it out and also flushed the ac system and replaced cabin filter. Although the rotten egg smell is gone, there's a new smell that is very annoying.

Since that time, when I fill up the tank, the dashboard says ~650KM till empty, which is about what I've seen over time. Now, as I drive, that number goes down about every 500 meters, even just sitting at a red light for a minute, it seems to lose about 2KM. By the time I've driven 20 km, the 650 number has dropped to 620 or so. The gas gauge doesn't move though, still shows completely full. It seems like there are other fuel system issues with this year/model so am reporting it here.
