general problems of the 2004 Mitsubishi Lancer

A recall was issued in 2005 for a potential issue in the power train. The recall stated that if the vehicle had a check engine light, the repair was to first try reprogramming the power train. If the check engine light appeared afterwards, the catalytic converter was to be replaced. The car was taken to the dealership for the above outlined service in 2005. The power train was reprogrammed and the check engine light went away, but the catalytic converter was not replaced. The check engine light later returned. A diagnostic revealed that the catalytic converter needed replaced. I believe that if the initial recall work in 2005 was properly fulfilled the catalytic converter would have been replaced. Mitsubishi has refused to repair of replace the catalytic converter, citing that the work done in the recall was sufficient. I contend that the recall repair was not thorough enough and that the catalytic converter should be repaired or replaced by the manufacturer.
