WHILE DRIVING THE VEHICLE AND PRESSING ON THE BRAKES THERE IS A LOUD CRANKING, GRINDING NOISE AND THE BRAKES APPEAR TO LOCK UP. THE SLIP, VDC OFF AND BRAKE LIGHTS ILLUMINATE ON THE DASHBOARD. I WILL USUALLY HAVE TO TURN THE VEHICLE OFF AND BACK ON FOR THE LIGHTS TO GO OFF AND TO DRIVE THE VEHICLE. THIS WORKS INTERMITTENTLY. *TR
THE EXHAUST MANIFOLDS ARE DEFECTIVE WHICH CREATES NOISE AND ALLOWS FUMES TO ESCAPE. INFINITI ADMITS THEY ARE DEFECTIVE BUT THEY WANT $2,800 TO $4,000 TO REPLACE THEM. THIS SHOULD BE CONSIDERED A SAFETY HAZARD AND INFINITI SHOULD REPLACE THEM FREE OF CHARGE. *TR

I HAVE A 2004 QX56 AND HAVE BEEN HAVING BRAKE PROBLEMS SINCE I FIRST GOT IT. THE BRAKES WERE REPLACED UNDER AN INITIAL RECALL IN 2005, BUT A NEW PROBLEM BEGAN IN 2006 AND HAS BEEN OCCURRING SINCE. INITIALLY, ONLY ABOUT ONCE EVERY 2 MONTHS, THE BRAKES WILL SPORADICALLY PULSATE AND THE CAR WILL COME TO A QUICK HALT. I WOULD JUST RESTART THE CAR AND IT WAS FINE. THE DEALERSHIP SAID IT WAS A FIRMWARE PROBLEM, AND "FLASHED" THE FIRMWARE. IT STILL KEPT HAPPENING, THEY FLASHED THE FIRMWARE OVER AND OVER AGAIN, AND THEN JUST SAID THERE WAS NOTHING MORE THAT COULD BE DONE. NOW THAT THE TRUCK IS OUT OF WARRANTY, THE DEALERSHIP SAYS IT IS BEING CAUSED BY A BAD BRAKE BOOSTER, AND WILL COST $1,100 TO FIX. BUT THIS HAS BEEN HAPPENING SINCE LONG BEFORE IT WAS OUT OF WARRANTY, AND NOW IT IS HAPPENING MUCH MORE OFTEN, ALMOST EVERY DAY. REVIEW OF DIFFERENT INFINITI FORUMS SHOWS MANY QX56'S, NISSAN ARMADAS, AND NISSAN TITANS ARE EXPERIENCING THIS PROBLEM. NISSAN HAS PUT OUT A SERVICE BULLETIN ACKNOWLEDGING THE PROBLEM, BUT THEIR SOLUTION DOES NOT SOLVE THE PROBLEM. THIS SHOULD REALLY BE INVESTIGATED FURTHER AND A RECALL ISSUED FOR WHATEVER THE CAUSE OF THE PROBLEM IS. *TR
Official recalls
110V517000 · Engine And Engine Cooling
Oct 28, 2010
NISSAN IS RECALLING CERTAIN MODEL YEAR 2004-2006 ARMADA, TITAN, INFINITI QX56 AND MODEL YEAR 2005-2006 FRONTIER, PATHFINDER AND XTERRA VEHICLES. THE INTELLIGENT POWER DISTRIBUTION MODULE (IPDM) ASSEMBLY CONTAINS AN ENGINE CONTROL MODULE (ECM) RELAY THAT HAS A DIODE FOR ELECTRICAL CURRENT NOISE REDUCTION. THE ECM RELAY MAY ALLOW SILICON VAPOR TO FORM AND, OVER TIME, THE SILICON EVAPORATES FROM THE DIODE MOLDING WHICH CAUSES SILICON OXIDE TO DEVELOP ON THE ECM RELAY CONTACT DUE TO ARCING.
Consequence & remedy
Consequence: THIS COULD CAUSE ENGINE STALLING INCREASING THE RISK OF A CRASH.
Remedy: DEALERS WILL REPLACE THE ECM RELAY INSIDE THE IPDM ASSEMBLY. THIS SERVICE WILL BE PERFORMED FREE OF CHARGE. THE SAFETY RECALL BEGAN ON DECEMBER 6, 2010. OWNERS MAY CONTACT NISSAN AT 1-800-647-7261.
