Car has code p0442 is possible purge valve covered under emission warranty?

[1Hunter99]

sonic 2015LT, starts rough after I add gas , its been doing that for a while , but only recently did I get the code p0442 , and now it struggles a bit to get speed and has a rough idle.in the case I need a purge valve or hose , will that be covered under emissions or CA PZEV emissions warranty? I can see it on the list But I just want to make sure b4 I take it to the dealer and they charge me $200+

40$ part do it yourself actually get cheaper than oem on ebay 10$ it's on top of the motor ezpeezee and don't top of your tank when getting gas that's what makes them go out evap tube ends up getting filled with gas go all in evap canister so instead of feul vapors being purged into the it's trying to suck up liquid fuel don't top of your tank also make sure nozzle is all the way in before you by this part try tightening your gas cap if that don't work get 1 those as well as purge valve solenoid
