Owner report 10249541 · 2008-11-22 (November 22, 2008)
THE ENGINE MAKES CLICKING/TAPPING SOUND AT START-UP, DEALER SERVICE DEPARTMENT CONTACTED. I WAS INFORMED THAT I NEED A "SPECIAL" OIL CHANGE, AND THEY'RE AWARE OF THE PROBLEM. AFTER RESEARCHING FOR THE SAME PROBLEM, IT LOOKS LIKE THIS 'SPECIAL' FACTORY OIL WILL BE NEEDED AND COST MORE THAN CONVENTIONAL OIL. HOWEVER, I WAS NOT INFORMED OF THIS SPECIFIC MATTER WHEN THE VEHICLE WAS PURCHASED NOR DOES IT SAY ANYWHERE IN MY OWNER MANUALS. APPARENTLY, ONLY THE DEALERSHIP HAD SUCH OIL AND I AM REQUIRE TO USE IT AFTER THE FACT. *TR

Owner report 10292951 · 2009-11-19 (November 19, 2009)
ON OCTOBER 23, 2009 I WAS DRIVING IN A PARKING STRUCTURE WITH MY INFINITI G37 2008 AND A PASSENGER. THERE WERE SEVERAL PARKING SPACES ON THE FOURTH FLOOR. THE PARKING STRUCTURE WAS VERY BUSY AND SLOW MOVING. I COASTED INTO THE PARKING SPORT SINCE I WAS DRIVING AT A CRAWL. WHEN I TOUCHED THE BRAKE LIGHT TO COME TO A COMPLETE STOP THE CAR SURGED FORWARD WITH SUCH A FORCE THAT IT HIT THE WALL THAT WAS APPROXIMATELY 3 FOOT IN FRONT OF PARKING CURB. IF IT HADN'T HAVE BEEN FOR THE WALL THE CAR WOULD HAVE GONE OVER. *TR

VEHICLE PULLS AND JUMPS ALL OVER THE PLACE, THIS IS SO PRONOUNCED THAT THE VEHICLE IS UNSAFE TO DRIVE ON MOST ROADS. I HAVE TAKEN THE VEHICLE TO THE DEALER 3 SEPARATE TIMES FOR THIS ISSUE, ON EACH OCCASION THEY HAVE PERFORMED AN ALIGNMENT BUT IT DOES NOT SOLVE THE PROBLEM. ON THE FOURTH VISIT TO THE DEALER AN INFINITI REPRESENTATIVE LOOKED AT THE VEHICLE AND DECLARED THAT THERE IS NOTHING WRONG WITH THE VEHICLE BUT CONFIRMED IN WRITING THAT THE VEHICLE DOES INDEED EXHIBIT THIS BEHAVIOR. ADDITIONALLY, THE VEHICLE WILL OCCASIONALLY HAVE A COMP…

08V521000 · Electrical System:Software | Air Bags
Reported: 2008-10-07 (October 7, 2008)
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.
