SERVICE BRAKES, HYDRAULIC
Campaign #09V144000 · Apr 30, 2009
Issue: JAGUAR IS RECALLING 14,551 MY 2004 XJ VEHICLES. A POTENTIAL CONCERN HAS BEEN IDENTIFIED WITH THE INSTALLATION OF A NOISE VIBRATION AND HARSHNESS (NVH) PAD FITTED TO THE UNDER TRAY AND ITS INTERACTION WITH THE REAR UNDER FLOOR BRAKE PIPES, REAR CROSS MEMBER BRAKE PIPES, AND THEIR UNIONS. A REVIEW OF VEHICLE BUILD CONDITIONS PROVIDES EVIDENCE THAT A TOUCH CONDITION CAN EXIST BETWEEN THE UNDER FLOOR AND CROSS MEMBER BRAKE PIPES AND THE NVH PAD AT THE REAR OF THE UNDER FLOOR UNDER TRAY. WHERE THE TOUCH CONDITION EXISTS, WATER AND DIRT CAN COLLECT AND BE HELD IN CONTACT WITH THE PIPES AND THEIR UNIONS, ABRADE THE CORROSION PROTECTION AND REDUCE THE CORROSION LIFE OF THE PIPES ACCORDINGLY.
Risk: CORROSION OF THE BRAKE PIPES CAN LEAD TO A LOSS OF MECHANICAL INTEGRITY OF THE BRAKING SYSTEM. THIS CAN RESULT IN EXTENDED BRAKE PEDAL TRAVEL COMBINED WITH REDUCED BRAKING PERFORMANCE IN THE CORRESPONDING BRAKE CIRCUIT. THE INSTRUMENT CLUSTER MAY DISPLAY THE WARNING MESSAGE 'FLUID LEVEL LOW', ALONG WITH THE BRAKE WARNING LAMP BEING ILLUMINATED. IN THE EVENT OF BOTH BRAKING CIRCUITS LOSING INTEGRITY AT THE SAME TIME, COMPLETE LOSS OF SERVICE BRAKES WILL OCCUR, THEREBY POTENTIALLY CAUSING A VEHICLE CRASH.
Fix: DEALERS WILL REMOVE THE UNDER TRAY AT THE REAR OF THE VEHICLE AND REMOVE AND DISCARD THE NVH PAD FITTED TO THE REAR OF THE UNDER TRAY. DEALERS WILL INSPECT THE REAR UNDER FLOOR AND REAR CROSS MEMBER BRAKE PIPES AND UNIONS FOR RED RUST. IF RED RUST IS PRESENT ON THE PIPES OR ON THE UNION, THE BRAKE PIPES AND UNION WILL BE REPLACED WITH NEW COMPONENTS OF THE SAME DESIGN. THIS SERVICE WILL BE PERFORMED FREE OF CHARGE. THE RECALL IS EXPECTED TO BEGIN DURING MAY 2009. OWNERS MAY CONTACT JAGUAR AT 1-800-452-4827.
POWER TRAIN:AUTOMATIC TRANSMISSION
Campaign #04V024000 · Aug 1, 2004
Issue: ON CERTAIN PASSENGER VEHICLES EQUIPPED WITH AUTOMATIC TRANSMISSIONS, WITH THE FORWARD DRIVE GEAR SELECTED AND THE VEHICLE STATIONARY OR IN A FORWARD MOTION, THE GEARBOX COULD POTENTIALLY SELECT REVERSE GEAR, WITHOUT INDICATION.
Risk: THIS FAILURE COULD RESULT IN A CRASH.
Fix: DEALERS WILL REPROGRAM THE TRANSMISSION CONTROL MODULE. THE RECALL BEGAN ON MAY 1, 2004. OWNERS SHOULD CONTACT JAGUAR AT 1-201-818-8500.
AIR BAGS:FRONTAL
Campaign #04V136000 · Mar 18, 2004
Issue: ON CERTAIN PASSENGER VEHICLES, THE PASSENGER AIR BAG TRIM COMPONENTS HAVE A POOR APERTURE EDGE.
Risk: SHOULD THE AIR BAG DEPLOY, IT COULD BE CUT, CAUSING IT TO NOT INFLATE PROPERLY, WHICH INCREASES THE RISK OF INJURY TO THE OCCUPANT IN A CRASH.
Fix: DEALERS WILL INSPECT THE PASSENGER AIR BAG APERTURE AND, WHERE NECESSARY, REMOVE ANY SHARP, SERRATED EDGES. THE RECALL BEGAN ON MAY 14, 2004. OWNERS SHOULD CONTACT JAGUAR AT 1-800-452-4827.
