THE PARKING BRAKE FAILED TO ENGAGE ON MY 2008 JEEP LIBERTY AUTOMATIC TRANSMISSION. WHILE THE PARKING BRAKE WAS FULLY ENGAGED WITH THE JEEP IN NEUTRAL THE JEEP ROLLED BACKWARD AND STRUCK THE WALL CAUSING MINOR RIGHT FRONT FENDER DAMAGE. FORTUNATELY THE JEEP HIT THE WALL STOPPING IT FROM ROLLING DOWN THE DRIVEWAY INTO TRAFFIC OR RUNNING OVER PEDESTRIANS. NOTE; THERE IS A RECALL ON THE 2008 JEEP LIBERTY, CHRYSLER RECALL #H28 WITH MANUAL TRANSMISSION BUT NOT ON THE AUTOMATIC WHICH USES THE EXACT SAME PARKING BRAKE SYSTEM. WHY ISN'T THERE A RECALL FOR THIS VEHICLE? EMERGENCY/PARKING BRAKE SYSTEM SHOULD BE THERE WHEN YOU NEED IT AND IF THE HYDRAULIC BRAKING SYSTEM SHOULD FAIL. THIS IS A VEHICLE SAFETY ALERT THAT MUST BE ADDRESSED. *TR
