The catalytic converter closest to the cylinder head can fail causing illumination of the Check Engine Light. Prompt repair of this problem is recommended because the catalyst material can be sucked into the engine and cause internal damage.

    I am about to go on a 2,000 mile road trip and this is come on. I passed emissions today but gave the the Catalytic Converter error message. I am getting checked out tomorrow by the dealership and I hope I do not have to replace anything.

    Intermittent check engine light. Dealer and alt repair shop advised bad cat. Took to a third shop for full breakdown of exhaust system and found cat split at the welds. Mechanic quote, "Robot did not have its coffee that day". Replaced at cost of 983.00. Core sent back to Nissan or would be charged another 140.00.

    Car runs fine but the "service engine soon" light came on that the repair shop said the codes showed a bad CC. We hope that's all that is wrong!

    Had a fuel system cleaning done which set the check engine light off. Turned out to be the front catalytic converter for precisely the reason stated. Fixed through replacement.
