2004 Infiniti QX56

DRIVING WITH MY TWO YOUNG CHILDREN ABOUT 35 MPH WHEN I DEPRESSED THE BRAKES THE CAR SHUTTERED BADLY ON THE FRONT END AND THE PEDDLE WENT ALL THE WAY TO THE FLOOR AND THE VEHICLE BARELY SLOWED DOWN. LUCKILY THERE WAS NO-ONE IN FRONT OF ME OR I WOULD HAVE CRASHED. PROBLEM CONTINUED UNTIL THE VEHICLE WAS TURNED OFF AND RE-STARTED. EXTREMELY DANGEROUS!!! MANY OTHER SIMILAR ACCOUNTS AND IT DOESN'T SOUND LIKE THERE IS A DIFINITIVE RESOLUTION TO THE PROBLEM EVEN AFTER SPENDING THOUSANDS AT THE DEALERSHIPS. *TR

YESTERDAY APRIL 10,2012 I WAS DRIVING AND NEED TO STOP THE MY QX56 I FEEL A COMPLETE BRAKE FAILURE,BRAKE WARNING LIGHT ON AND A LOUD NOISE UNDER THE VEHICLE. BRAKE PEDAL DOING ALL THE DOWN TO THE FLOOR. AFTER TURNING THE VEHICLE OFF AND RESTART, EVERYTHING TURN BACK TO THE NORMAL AND WARNING LIGHT GONE. THIS IS SERIOUS ISSUE AND MANUFACTURER SHOULD FIX THE PROBLEM BEFORE ANY BODY DIE. *TR

TODAY, WHILE MY WIFE WAS DRIVING OUR 2004 INFINITI QX56 WITH 106,134 MILES, SHE EXPERIENCED A COMPLETE BRAKE FAILURE, ALONG WITH THE "BRAKE" DASHBOARD WARNING LIGHT. IT WAS DESCRIBED TO ME AS THE STEERING WHEEL AND BRAKE PEDAL SHAKING, A LOUD NOISE FROM UNDER THE VEHICLE, AND THE BRAKE PEDAL GOING ALL THE WAY TO THE FLOOR. THIS EXACT SAME ISSUE IS ALL OVER THE INFINITI QX56 / NISSAN ARMADA FORUM, THE INTERNET, AND WWW.MYCARSTATS.COM SITE TO WHICH I'M A SUBSCRIBER. IT'S RIDICULOUS THAT WITH THE NUMBER OF STATED OCCURRENCES OF THIS FAILURE ON THESE VEHICLES THAT A FORMAL RECALL HAS NOT BEEN MANDATED TO CORRECT THIS PROBLEM. AS WITH MOST OF THE OTHER REPORTS OF THIS HAPPENING, TURNING OFF AND RESTARTING THE VEHICLE ELIMINATED THE "BRAKE" WARNING LIGHT AND THE NORMAL PEDAL FEEL RETURNED TO OUR VEHICLE. THERE IS AT LEAST ONE REPORT OF THIS FAILURE RESULTING IN A SEVERE, ALMOST FATAL, ACCIDENT AND I'M SURE IF ACTUALLY INVESTIGATED THAT THERE ARE PROBABLY MORE. NISSAN - INFINITI - NHTSA: DO SOMETHING FORMAL ABOUT THIS IMMEDIATELY BEFORE SOMEONE, THEIR WIFE, AND OR CHILDREN ARE HURT OR KILLED! *TR

TL* THE CONTACT OWNS A 2004 INFINITI QX56. THE CONTACT WAS DRIVING 30 MPH WHEN THE BRAKES WERE DEPRESSED AND A GRINDING NOISE EMITTED AS THE VEHICLE FAILED TO STOP PROPERLY. THE EMERGENCY BRAKE LIGHT ILLUMINATED DURING THE FAILURE. THE VEHICLE WAS TAKEN TO THE DEALER AND THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED AND THE VIN WAS UNKNOWN. THE FAILURE MILEAGE WAS 105,000 AND THE CURRENT MILEAGE WAS 135,000.

THIS 95% TOTAL BREAK FAILURE HAS HAPPENED 2 SEPARATE TIMES 8/2010 AND 3/2011; AND WHILE NO ACCIDENT, THERE COULD EASILY HAVE BEEN ONE HAD I BEEN TRAVELING AT A HIGHER RATE OF SPEED, OR IF THERE HAD BEEN OTHER VEHICLES AROUND ME. APPLIED BREAK, IMMEDIATELY BRAKE PEDAL SUNK TO THE FLOOR, BREAK LIGHT ON DASH CAME ON, FRONT BREAKS BEGAN MAKING HARSH GRINDING SOUNDS (AS WHEN SLIP CONTROL ENACTS); HAD THERE BEEN CARS IN FRONT OF ME I WOULD NOT HAVE BEEN ABLE TO STOP W/OUT HITTING THEM. EVEN WITH FOOT TO FLOOR VEHICLE DID NOT STOP, DOWN SHIFTED INTO 1ST GEAR, AND FINALLY VEHICLE SLOWED AND WAS ABLE TO STOP. PULLED OVER AND TURNED OFF CAR; AFTER TURNING CAR BACK ON BRAKE LIGHT ON DASH HAD GONE AWAY AND BRAKES WERE ACTING NORMAL. THIS IS A MAJOR SAFETY HAZARD AND SOMEONE MAY DIE FROM THIS. THE FRONT DISCS ON THIS VEHICLE ARE NO GOOD EVEN AFTER INFINITI/NISSAN HAS DONE THEIR SO CALLED REPAIR AND CONTINUE TO PREMATURELY WARP.A CLASS ACTION LAW SUIT NEEDS TO BE FORMED TO DEAL RESOLVE THIS MATTER INDEFINITELY. DEALER SUBSEQUENTLY REPROGRAMED VDC CONTROL.

WHILE DRIVING QX56 AT APPROX 40 MPH BRAKE LIGHT ON DASH CAME ON. AT INTERSECTION TO TURN LEFT BRAKES WOULD NOT FUNCTION AND SLOWING DOWN WAS DIFFICULT. THERE WAS A LOUD CLUNK AND "BOING" SOUND WHEN BRAKES WERE APPLIED. TURNED TO AVOID TRAFFIC AND STARTED UP HILL ALLOWING SPEED TO DECREASE. MOTOR WAS TURNED OFF. WHEN RESTARTED TO EXAMINE FAILURE LIGHT WAS NO LONGER ON AND BRAKE SEEMED TO WORK FINE. CONTACTED LOCAL INFINITY DEALER, WAS TOLD IT WAS BRAKE BOOSTER AND WOULD MOST LIKELY NEED REPLACED. WAS TOLD THERE WAS NO SERVICE BULLETIN OR RECALL BUT THEY HAVE SEEN THE ISSUE QUITE A FEW TIMES. *KB

PERIODICALLY, ON THE ORDER OF ONCE EVERY MONTH OR TWO MONTHS, THE ANTILOCK BRAKES BECOME ERRATIC. THE PEDAL GOES SOFT AND THE BRAKES ENGAGE EXTREMELY VIOLENTLY. WHEN IT HAPPENED THE FIRST TIME I PULLED OVER TO THE SIDE OF THE ROAD AND CALLED MY INFINITI DEALER. I KEPT THE ENGINE RUNNING WHILE I EXPLAINED WHAT HAPPENED AND WAS TOLD TO TURN OFF THE ENGINE, WAIT ABOUT TEN SECONDS AND THEN RESTART THE SUV. THE BRAKES WORKED NORMALLY AFTER THAT. I WAS TOLD THE "COMPUTER HAD TO BE RE-BOOTED". THIS CONTINUES TO HAPPEN ON AND OFF ABOUT EVERY MONTH OR TWO. NEVER WAS GIVEN A SATISFACTORY EXPLANATION AS TO WHY THIS OCCURS. WHEN IT HAPPENS IF THERE IS NO TRAFFIC AROUND, I PUT THE CAR INTO NEUTRAL, TURN OFF THE KEY, THEN RESTART THE CAR AND THE PROBLEM RESOLVES. IF I AM IN TRAFFIC I SLOW DOWN GINGERLY, THEN PULL OFF TO THE SIDE OF THE ROAD AND TURN OFF THE KEY AND RESTART THE ENGINE. THIS RESOLVES THE PROBLEM UNTIL THE NEXT TIME. *TR

TL* THE CONTACT OWNS A 2004 INFINITI QX56. THE CONTACT WAS DRIVING APPROXIMATELY 60 MPH WHEN HE DEPRESSED THE BRAKES AND LOST CONTROL OF THE VEHICLE. THE VEHICLE WAS TAKEN TO THE DEALER WHERE THE CONTACT WAS ADVISED THAT THE ROTORS WERE SEVERELY WARPED. THE DEALER MADE FIVE SEPARATE ATTEMPTS TO REPAIR THE FAILURE BUT TO NO AVAIL. THE MANUFACTURE WAS INFORMED OF THE FAILURE WHO ADVISED THE CONTACT THAT THERE WERE NO RECALLS ON THE VEHICLE AND OFFERED NO ADDITIONAL ASSISTANCE. THE VEHICLE WAS NOT REPAIRED. THE CURRENT MILEAGE WAS 46,200 AND THE FAILURE MILEAGE WAS 10,200.

MAJOR COOLANT ISSUE. REPLACED 4 RADIATORS, 1 WATER PUMP. ALL UPPER AND LOWER HOSES. DEALER HAS HAD SUV IN MORE THAN 9 TIMES THIS YEAR WITH SAME ISSUE. WHILE DRIVING COOLANT SMELL IS IN VENTS. UP THE HOOD AND ITS SPLASHED ALL OVER THE MANIFOLD. ALSO ABS ISSUE. BRAKING MECH MAKES METAL TO METAL SOUND AND IF U CUT OFF CAR AND TURN BACK ON.. IT RESUMES AS NORMAL. *TR
