Yes, I wondered about that, too. When we took it in for inspection, it failed because of an exhaust leak but I don’t know where it was leaking. We have taken it to our regular mechanic for repairs, a local independent shop. They have seemed honest about what we need to repair & what we can do without & still drive safely. I will definitely ask about the catalytic converter scan code & get a second opinion. Any other questions I could ask that would make me sound like I know what I’m talking about?
