Question about 2007 Chevrolet Colorado
Clear the codes and check that the gas cap is seating properly.
No reason to replace parts for a possibly loose or worn out gas cap.
If codes return, trouble shoot first occurance.

First......clear those codes and see if they return before doing anything.Purge valve is on the vent line from tank to engine ,usually in the engine compartment,and vent valve is on the line from tank to outside air,usually by the fuel tank.Don't change any parts until you check them and their circuits with a good scan tool.

Was the repair facility a Hyundai dealership? If not, I would recommend a second opinion from a certified dealership. This way you will have more information and a better idea as to how much the repair will cost.
The canister in your evaporator system may need to be replaced. These will fill with emissions and cause a trouble code. Hope this helps.

Look on the passenger front of the engine compartment near the radiator. It will be mounted on a bracket, it will have two hoses attached to it, and have a single connector.

Evaporative Emission Control System Incorrect Purge Flow
What does that mean?
This indicates that a part of the EVAP control system is no longer functioning correctly. The EVAP system consists of many parts, including (but not limited to) the gas cap, fuel lines, carbon canister, purge valve, and other hoses. The (EVAP) emission control system prevents the escape of fuel vapors from a vehicle's fuel system. Fuel vapors are routed by hoses to a charcoal canister for storage. Later, when the engine is running a purge control valve opens allowing intake vacuum to siphon the fuel vapors into the engine.
EVAP emission canister purge is controlled by a valve which allows engine vacuum to pull stored fuel vapors from fuel tank into the engine to be burned, rather than be vented to atmosphere. A vacuum switch is used to detect when flow exists. If the PCM commands purge and sees that the switch is closed (indicating no detected purge flow) P0441 is set.
Likely, no symptoms will be discernible to the driver, other than the illuminated Check Engine Light.
A code P0441 could mean one or more of the following has happened:
With a P0441 OBD-II trouble code, diagnosis can be tricky at times. Here are some things to try:
