The gas cap seal is not working as it should. It only last two years with 40k miles. The vehicle trip on trouble code: p0456 evaporative emissions system - small leak detected. It happen 4 out of 5 times I fill up my gas tank. Each fill up, I verify that the gas cap is tight - click a couple times. The gas cap is cheap. I can replace it myself but does not like Subaru to become cover up like Toyota.
