Hi I just bought a 2013 base model Veloster. Is there any advice you would give me. i have 2 issues with the car. The catalytic converter was replace in October and there is an error in the code saying bank one is below required threshold. then sometimes when i'm driving i hear a clicking sound from the front of the car. when i shift from 1st to 2nd there "can be but is not always there" a grinding/ clicking sound. kind of like an animal in a sense. It kind of sounds like a rattle, like two pieces of metal tapping slightly and quickly. If anyone has had this, or not i was hoping the more experienced owners would have some ideas on what this could be.
