I am having this same exact issue as many on here about the P0455 and other issues. The dealer first told me a year ago that the gas cap was loose. Cleared the code and sent me on my way. Then in Jan of this year, I get the same P0455 code and they replaced the EVAP solenoid as you first did for $187 parts and labor. Now the eng light is back on and had it checked today. Now they say its the tank pressure sensor. $500 to drop the tank and replace the $80 part.
Man - between the oil usage, these sensors, the pinion bearing going out, the crappy door handles & brakes, I'm about done with the POS.
I assume dropping the tank myself isn't something I want to do?
