Hello, I have a 2014 Honda accord sport and the check engine light came on so I took it to a local well known muffler shop and the code came back for the front catalytic converter...the car at the time had 125,000 miles on it and was told the car was too new so the converter had to come from the dealer so after paying a pretty penny I had it replaced drove around and around 300 miles later the check engine light came back on so took it back to the same place and code came back for the front catalytic converter again. So Honda sent a replacement the converter again and had it changed again at the same shop now the check engine light is back on if it is the catalytic converter again what can be causing this?

 

It depends on what the code is. And there is really no way your cat is bad with so few miles. It's likely either a wiring issue or the ecu is somehow bad.
