Defect description
ON THE INVOLVED VEHICLES, THE BRAKE MASTER CYLINDER MAY HAVE BEEN ASSEMBLED WITH RESERVOIR MOUNTING BOLTS THAT WERE IMPROPERLY PROCESSED. THIS COULD MAKE THESE BOLTS BRITTLE AND SUBJECT TO BREAKING. IF BREAKAGE OCCURS, A BRAKE FLUID LEAK MAY DEVELOP BETWEEN THE RESERVOIR AND MASTER CYLINDER. LOSS OF BRAKE FLUID WOULD ADVERSELY AFFECT VEHICLE BRAKING CAPABILITY.
Manufacturer remedy
DEALER WILL REPLACE THE MASTER CYLINDER RESERVOIR MOUNTING BOLTS WITH AN IMPROVED TYPE, WITHOUT CHARGE TO OWNER.
THE FRONT SUSPENSION CONTROL ARMS WERE ASSEMBLED WITH BALL JOINTS WHICH MAY CONTAIN SOCKETS THAT WERE NOT PROPERLY HEAT-TREATED. THIS MAY CAUSE THE SOCKET TO WEAR RAPIDLY AND ALLOW THE BALL JOINT STUD TO SEPARATE FROM THE SOCKET, CAUSING EITHER THE LEFT OR RIGHT WHEEL SUSPENSION TO COLLAPSE.
Manufacturer remedy
DEALER WILL INSPECT AND, WHERE NECESSARY, WILL REPLACE THE BALL JOINTS WITHOUT CHARGE TO OWNER.
