I filled my 09 with gas for the first time and noticed a difference from my 04 with the gas cap. On the 04, when tightening the cap, I could keep turning it for several clicks after the cap was screwed on. On the 09 the cap stops with one click and I can't turn it any further. Is this a change in gas caps, or do I possible have a defective one? Never mind ... found the answer. The gas cap was changed and will only click once.
