Recalls (2)

  • POWER TRAIN:MANUAL TRANSMISSION · Campaign 07V307000 · Jul 19, 2007

    Defect: ON CERTAIN VEHICLES EQUIPPED WITH 5-SPEED MANUAL TRANSMISSIONS, DUE TO IMPROPER SHAPE OF THE CLIP, THE RETAINING CLIP THAT KEEPS THE GEAR SHIFT CABLE ATTACHED TO THE GEAR SHIFT LEVER CAN CONTACT THE GEAR SHIFT LEVER HOUSING IF EXCESSIVE LATERAL FORCE IS APPLIED WHEN SHIFTING TO FIRST GEAR.

    Consequence: REPEATED SHIFTING IN THIS MANNER CAN EVENTUALLY CAUSE THE RETAINING CLIP TO BREAK. IF THE RETAINING CLIP BREAKS, THE SHIFT CABLE CAN BECOME DISCONNECTED FROM THE SHIFT LEVER, RESULTING IN LOSS OF THE ABILITY TO CHANGE TRANSMISSION GEARS.

    Remedy: DEALERS WILL REPLACE THE GEAR SHIFT CABLE RETAINING CLIP WITH A CLIP THAT HAS A DIFFERENT SHAPE. THE RECALL BEGAN ON AUGUST 13, 2007. OWNERS MAY CONTACT AMERICAN SUZUKI AT 1-800-934-0934.

  • VISIBILITY:WINDSHIELD · Campaign 03V223000 · Jun 18, 2003

    Defect: CERTAIN PASSENGER (111 MY 2002 ESTEEM, 777 MY 2002 AERIO, 2,368 MY 2003 AERIO) AND SPORT UTILITY (324 MY 2002 GRAND VITARA, 274 MY 2003 GRAND VITARA, 684 MY 2002 GRAND VITARA XL-7, AND 781 MY 2003 GRAND VITARA XL-7) VEHICLES FAIL TO COMPLY WITH THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 212, 'WINDSHIELD MOUNTING." THE WINDSHIELD MAY NOT BE PROPERLY SECURED TO THE VEHICLE BODY DUE TO INSUFFICIENT ADHESION BETWEEN THE PAINT APPLIED DURING THE SECOND-STAGE PAINTING PROCESS AND THE PAINT APPLIED DURING FINAL-STAGE PAINTING.

    Consequence: IF THE WINDSHIELD IS NOT PROPERLY SECURED, IT MAY SEPARATE FROM THE VEHICLE DURING A CRASH WHICH COULD RESULT IN THE EJECTION OF UNBELTED OCCUPANTS, INCREASING THE RISK OF SEVERE INJURY OR DEATH.

    Remedy: DEALERS WILL INSPECT THESE VEHICLES. VEHICLES THAT ARE FOUND TO HAVE INSUFFICIENT PAINT ADHESION WILL EITHER HAVE THE PROBLEM REMEDIED BY REPAINTING, OR WILL BE REPLACED, OR REPURCHASED AND DESTROYED. OWNER NOTIFICATION BEGAN ON JULY 8, 2003. OWNERS SHOULD CONTACT SUZUKI AT 1-800-934-0934.
