SUBARU OF AMERICA, INC. HAS DETERMINED VEHICLES AFFECTED BY THIS SERVICE PROGRAM REQUIRE FRONT CATALYTIC CONVERTER REPLACEMENT AND ECM REPROGRAMMING. FOR VEHICLES AFFECTED BY THIS SERVICE PROGRAM, EFFICIENCY OF THE FRONT CATALYTIC CONVERTER MAY DEGRADE OVER TIME. IF THE CATALYTIC CONVERTER EFFICIENCY DEGRADES BEYOND AN ACCEPTABLE LEVEL, THE VEHICLE MAY BE RELEASING AIR POLLUTANTS WHICH EXCEED CALIFORNIA STANDARDS. TO CORRECT THIS CONDITION, IT WILL BE NECESSARY TO REPLACE THE FRONT CATALYTIC CONVERTER AND REPROGRAM THE ECM SOFTWARE LOGIC, IMPROVING MANAGEMENT OF THE CATALYTIC CONVERTER. THIS SOFTWARE CHANGE WILL NOT ADVERSELY AFFECT FUEL ECONOMY OR PERFORMANCE OF THE VEHICLE.
