Catalytic converters are factory defective My vehicle has less than 80K miles and used as pleasure vehicle. The problem has been inspected and confirmed by a reputable independent service provider. Warning lights came on and upon inspection it was determined that 3 catalytic converters are defective. My spouse also complains about a bad odor when vehicle is on but not running.
