Just had the UB4 recall done on my 15 Challenger SXT Plus, new evap canister. Now a couple weeks later I am getting 3 codes P0440 (General EVAP failure), P0456 (EVAP Small leak), P0457 (Loose fuel cap). I replaced my fuel cap, made sure it was seated correctly and ran through engine restart more than 6 times out running errands and it hasn't gone away. Anyone seen this before after that recall? Could the tech have screwed up the install? Anything else it could be?
