CERTAIN AFTERMARKET BRAKE HYDRAULIC MASTER CYLINDERS SOLD AS REPLACEMENT BRAKE CYLINDERS FOR CERTAIN FORD, DAIMLERCHRYSLER, AND JEEP PASSENGER VEHICLES. THESE BRAKE CYLINDERS WERE SOLD UNDER THE BRAND NAMES OF NAPA, RAYBESTOS, AIMCO, AC DELCO, CARQUEST, BENDIX, AND WAGNER. ONLY PRODUCTS THAT WERE MANUFACTURED FROM JULY 27, 2005 THROUGH JANUARY 17, 2006 (DATE CODES 0529 THROUGH 0602) ARE SUBJECT TO THIS RECALL. WHEN SUBJECT TO VERY COLD TEMPERATURES, AN INTERNAL SEAL IN THE MASTER CYLINDER COULD LOSE FLEXIBILITY AND MAY CAUSE BRAKE FLUID TO LEAK.
LOSS OF BRAKE FLUID CAN LEAD TO A DECREASE IN BRAKE LINE PRESSURE AND AN INCREASE IN STOPPING DISTANCE, WHICH CAN RESULT IN A VEHICLE CRASH.
CERTAIN AFTERMARKET AIRTEX ELECTRIC FUEL PUMPS INSTALLED FOR USE AS REPLACEMENT EQUIPMENT FOR CERTAIN 1997-2004 JEEP WRANGLER; 1997-2001 JEEP CHEROKEE; 1997-2004 JEEP GRAND CHEROKEE; AND 2000-2003 DODGE DAKOTA VEHICLES. THE PLASTIC ELECTRICAL GROMMET CONNECTORS AT THE TOP OF THE FUEL PUMP MODULE ARE NOT COMPATIBLE WITH AUTOMOTIVE FUELS AND MAY DEGRADE CAUSING A POTENTIAL LEAK PATH FOR FUEL.
IN THE PRESENCE OF AN IGNITION SOURCE, A FUEL LEAK COULD RESULT IN A FIRE.
ON CERTAIN SPORT UTILITY VEHICLES, DUE TO A RECENT SOFTWARE PROGRAMMING ERROR, THE TIRE, WHEEL, AND INFLATION PRESSURE INFORMATION WAS INADVERTENTLY OMITTED FROM THE VEHICLE CERTIFICATION LABEL.
THE VEHICLE OWNER WOULD NOT BE AWARE OF THE TIRE, WHEEL, AND INFLATION PRESSURE INFORMATION FOR THEIR VEHICLE.
