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

SEAT BELTS
THE AIRBAG WARNING LIGHT COMES ON. DEALER STATES THAT IT HAS TO DO WITH THE SEAT BELT PRETENSIONER WIRING. OWNERS MANUAL STATES THAT IF THIS LIGHT COMES ON, IT MOST LIKELY MEANS THAT THE AIRBAGS ARE NO LONGER FUNCTIONAL. SEAT BELTS AND AIRBAGS ARE KEY SAFETY MEASURES. TO HAVE THEM BE NOT FUNCTIONING IS A MAJOR CONCERN. IF YOU PUT IN A GOOGLE SEARCH FOR "AIR BAG LIGHT FLASHING INFINITI QX56" YOU WILL FIND HUNDREDS OF POSTINGS FROM PEOPLE WITH SIMILAR PROBLEMS, SO THIS IS NOT AN ISOLATED INCIDENT. *TR
