At Don Herring Irving Mitsubishi, catalytic converters have been cut off 21 new cars in recent weeks. “Very frustrating but it’s more frustrating for us for our customers that are being bombarded by this,” said service manager Kevin Rogers. Rogers says the average repair costs up to $3,500 and could take more than a month to fix because of a limited supply. "If we didn't have this epidemic going on we would not have this supply issue," Rogers said. Cars in every corner of North Texas are being hit. In Plano, there've been so many stolen, police started a catalytic converter theft task force.
