2007 Nissan Altima electrical system problems

Defect

NISSAN IS RECALLING 204,361 MY 2007-2008 ALTIMA, ALTIMA HYBRID, 350Z, 350Z ROADSTER, MY 2008 ALTIMA COUPE, ROGUE, MY 2009 MURANO, AND INFINITI MY 2007-2008 G35 SEDAN, MY 2008 G37 COUPE AND EX35 PASSENGER VEHICLES EQUIPPED WITH CONTINENTAL AUTOMOTIVE SYSTEMS' OCCUPANT CLASSIFICATION SYSTEM (OCS) CONTROL UNITS. A VARISTOR IN THE OCS CONTROL UNIT LOCATED IN THE PASSENGER SEAT CUSHION MAY HAVE BEEN MANUFACTURED OUT OF SPECIFICATION. UNDER CERTAIN CONDITIONS, THIS COULD CAUSE AN INTERRUPTION OF SIGNAL BETWEEN THE OCS AND THE AIR BAG CONTROL UNIT (ACU).

Consequence

THIS COULD RESULT IN THE PASSENGER AIR BAG BEING SUPPRESSED WHICH COULD FAIL TO PROVIDE ADEQUATE PROTECTION IN THE EVENT OF A CRASH.

Remedy

DEALERS WILL TEST THE SIGNAL BETWEEN THE OCS AND ACU SYSTEMS USING A SPECIAL TOOL TO CHECK THAT IT IS FUNCTIONING AS DESIGNED. IF NECESSARY, THE SEAT CUSHION (CONTAINING OCS HARDWARE) WILL BE REPLACED WITH A NEW ONE MANUFACTURED TO SPECIFICATION. THE RECALL BEGAN ON NOVEMBER 4, 2008. OWNERS MAY CONTACT NISSAN AT 1-800-647-7261 OR INFINITI AT 1-800-662-6200.

Defect

ON CERTAIN PASSENGER VEHICLES THAT HAVE HAD THE BODY CONTROL MODULE (BCM) REPLACED DURING SERVICE AT A DEALERSHIP, THE TIRE PRESSURE MONITORING SYSTEM (TPMS) MAY HAVE BEEN INADVERTENTLY DEACTIVATED DUE TO AN ISSUE WITH THE DEALER SERVICE SOFTWARE. IF THE TPMS IS TURNED OFF, IT WOULD NOT ALERT THE DRIVER TO A DECREASE IN THE TIRE PRESSURE AS DESIGNED.

Consequence

DRIVING ON UNDER-INFLATED TIRES IS UNSAFE AND COULD RESULT IN A CRASH.

Remedy

DEALERS WILL CHECK THE TPMS FUNCTION AND REACTIVATE IT IF NECESSARY. THE RECALL BEGAN ON JANUARY 18, 2008. OWNERS MAY CONTACT NISSAN AT 1-800-647-7261.
