Car smells gas on the inside whether it's full tank or half tank gas. Also on full tank gas, gas comes out from gas cap when park uphill and happened once on level park. I don't know where to begin checking. Sometimes I smell gas outside on rear of car when parked. Any pics or video for troubleshooting would be appreciated very much. Any idea how much is repair? Thanks.

Sounds like the spring on the end of your filler neck has failed. There is a plastic flap at the very end of your filler neck that keeps gas from flowing up the filler tube while driving. I don't know if you can buy the spring separate or not, but you may have to drop your gas tank to get access to all the screws holding the filler neck to the tank.

Gen 5 filler tubes are notorious for rusting, next time you fill up check and smell the wheel arch where the filler cap is.
