2014 Nissan Armada POWER TRAIN,SERVICE BRAKES

WHEN PARKED ON STEEP INCLINED DRIVEWAY, THE PARKING BRAKE WILL NOT ENGAGE AND VEHICLE CONTINUES TO ROLL. WHEN SHIFTING TO PARK ON STEEP INCLINED DRIVEWAY, THE VEHICLE CONTINUES TO MOVE UNTIL IT CATCHES. WHEN APPLYING FOOT BRAKE, THEN SHIFTING INTO PARK AND APPLYING PARKING BRAKE THE VEHICLE CONTINUES TO MOVE UNTIL IT CATCHES. WHEN VEHICLE IS ON FLAT SURFACE AND ONLY PARKING BRAKE IS APPLIED, THE VEHICLE WILL MOVE FORWARD IN NEUTRAL WHEN VEHICLE IS AT HIGH IDLE (WARMING UP) AND WILL MOVE EASILY WITHOUT RESISTANCE WHEN PUT IN FORWARD OR REVERSE. THE PEDAL CAN BE PUSHED ALL THE WAY TO THE FLOOR BOARD AND WILL NOT ENGAGE. THE NISSAN MANUAL STATES IN MAINTENANCE CHAPTER (8-3) PARKING BRAKE: CHECK THE PARKING BRAKE OPERATION REGULARLY. VEHICLE SHOULD BE SECURELY HELD ON A FAIRLY STEEP HILL WITH ONLY THE PARKING BRAKE APPLIED. IF THE PARKING BRAKE NEEDS ADJUSTMENT, SEE A NISSAN DEALER. THE MOST COMMON USE FOR A PARKING BRAKE IS TO KEEP THE VEHICLE MOTIONLESS WHEN IT IS PARKED AND TO PREVENT DAMAGE ON THE TRANSMISSION/PARKING PAWL (ESPECIALLY WHEN PARKED ON AN INCLINE). I HAVE SEEN 2 LOCAL NISSAN DEALERS AND THEY SAY THIS IS NORMAL AND THEY DON'T HAVE A SOLUTION TO FIX THE PARKING BRAKE.
