2004 Infiniti QX56 brake problems

SERVICE BRAKES

My wife was driving home from work, said brake is failing, makes loud grindy, rattling noise when brake is applied. Once the car is turn off and back on, everything is back to normal. When I got home, i took the wheels off to check everything was ok, pads were almost new, which I replaced last year. Drove around for 10 miles no problem. This is a serious safety issue which Nissan/Infiniti should take care of.

THE VEHICLE'S BRAKE WARNING LIGHT KEEPS COMING ON. ROTORS ARE FINE. BRAKE FLUID LEVEL IS HIGH. YET, WHEN I APPLY MY FOOT ON THE BRAKE, THE WARNING LIGHT COMES ON AND THERE IS ALSO A BAD SOUND ON THE FRONT WHEELS THAT SOUNDS LIKE METAL TO METAL (THERE IS A VIBRATION). ONCE I PULL OVER AND TURN THE VEHICLE OFF FOR A MINUTE OR SO, I AM ABLE TO CONTINUE. HOWEVER, THE WARNING LIGHT COMES BACK ON MOMENTS LATER. THIS IS GETTING VERY DANGEROUS AS IT MAY TRIGGER ME TO REAR END THE VEHICLE IN FRONT OF ME. THE PROBLEM HAS BEEN HAPPENING FOR THE PAST EIGHT MONTHS. HOWEVER, IT HAS BEEN GETTING WORST. THE CRUISE CONTROL LIGHT ALSO COMES AND STAYS ON. PLEASE HELP.

ON TWO SEPARATE OCCASIONS WHILE THE CAR WAS MOVING IN A DRY PARKING LOT AND APPLYING MY BRAKES, MY ABS BRAKES KICKED ON FOR NO REASON AND THE CAR WAS DIFFICULT TO CONTROL AND STOP. THE LIGHT CAME ON AS WELL AND I HEARD ALOT OF GRINDING. THIS WAS VERY SCARY AS BOTH TIMES I HAD MY CHILDREN IN THE CAR. THE ONLY WAY TO RESET ABS WAS TO TURN OFF VEHICLE. I AM SO AFRAID THAT THIS WILL HAPPEN AGAIN AND I MAY NOT BE ABLE TO STOP. I AM NOW AFRAID TO DRIVE AND AM THINKING ABOUT SELLING IT BECAUSE I FEEL IT IS NOT SAFE TO DRIVE.

I GET A BRAKE LIGHT AND A SLIP LIGHT SOMETIMES WHEN APPLYING THE BRAKES. MAKES AN AWFUL NOISE AND SOMETIMES THE BRAKES FAIL TO OPERATE. I HAVE TO TURN THE CAR OFF AND RESTART IT TO RESET SOMETHING AND THEN ITS FINE FOR A FEW DAYS AND COMES BACK. IT IS VERY SCARY. OTHERS WHO HAVE THE SAME VEHICLE HAVE COMPLAINED OF THE SAME THING. SAYING THEY THINK THE BRAKE MASTER CYLINDER IS DEFECTIVE. I HAVE ALSO HEARD OF PEOPLE CRASHING THEIR SUV BECAUSE OF THIS. THIS HAPPENS JUST WHEN APPLYING THE BRAKES. I SEE THIS A LOT IN THE FORUMS AND WONDER WHY THEY HAVEN'T RECALLED THIS DANGEROUS DEFECT. THIS HAS BEEN HAPPENING NUMEROUS TIMES IN THE PAST 5 YEARS.

WHILE DRIVING AT LOW/HIGH SPEEDS, THE BRAKE LIGHT WILL JUST TURN ON UNEXPECTEDLY. ALSO, THE ABS BRAKES SEEM TO FAIL WHERE YOU HAVE TO PRESS THE BRAKE PEDAL TO THE FLOOR. THE ONLY WAY TO TEMPORARILY FIX THIS IS TO TURN THE ENGINE OFF AND TURN IT BACK ON FOR THE BRAKE LIGHT TO GO AWAY. AGAIN, THIS WILL OCCUR AT LEAST 1-2 TIMES A DAY AND/OR 28 TIMES IN A MONTH WHILE DRIVING. THIS IS A VERY DANGEROUS SITUATION TO PUT A DRIVER IN ON THE HIGHWAY OR OTHER ROADWAYS.

THE BRAKE PADS AND ROTORS ARE NEW.

AS I WAS TRAVELING ON A CITY STREET, THE BRAKES ON MY 2004 INFINITI QX56 STARTED MAKING A GRINDING NOISE AND THE BRAKE LIGHT ON DASH BOARD WENT ON MAKING IT HARD TO COME TO A STOP.

THE FIRST TIME I HAD ISSUES WITH MY BRAKES I WAS FORTUNATE ENOUGH TO BE PARKED. I TURNED THE VEHICLE ON AND TRIED TO RELEASES THE EMERGENCY BRAKE BUT THE LIGHT WOULDN'T DISENGAGE. I PUT THE VEHICLE IN REVERSE AND THE APPLIED PRESSURE TO THE BRAKE BUT THE BRAKES DIDN'T WORK. THEN THE VEHICLE MADE A SEVERE GRINDING NOISE. I THEN TURNED OFF THE VEHICLE AND THE PROBLEM WENT AWAY. I THEN CALLED THE DEALERSHIP AND ASKED IF THERE WAS A RECALL FOR THIS PROBLEM AND THEY SAID "NO". THE SECOND TIME IT HAPPENED TO ME I WAS DRIVING ON THE ROAD. I NOTICE THE BRAKE LIGHT TURNED ON, SO I SLOW APPLIED PRESSED TO THE BRAKE PEDDLE AND THE VEHICLE WOULD STOP AND BEGAN TO SHAKE FURIOUSLY AS IF IT WAS SKIDDING ON THE ROAD. FORTUNATELY, THEIR WASN'T ANYONE ON THE ROAD. THE VEHICLE FINALLY CAME TO A STOP AND I WAS LUCKY ENOUGH TO PULL OFF THE ROAD. I TRIED PRESSING THE PARKING BRAKES TO RELEASE THE LIGHT BUT THAT DIDN'T WORK SO I TRIED SHUTTING THE VEHICLE OFF. I TURNED THE VEHICLE BACK ON AND THE LIGHT WAS GONE. I SLOWLY BEGAN TO DRIVE AND TEST THE BRAKES AND THEY WORK AGAIN. I HAVE GONE TO THE DEALERSHIP AND THEY TOLD ME AGAIN THERE WAS NO RECALL ON THE ISSUE AT HAND. THE SERVICE DEPARTMENT SAID IT COULD BE THE BRAKE BOOSTER BUT THEY COULDN'T FIND AN ISSUE WITH IT SO THEY DIDN'T REPLACE IT.

WHILE DRIVING THE EMERGERCNY BRAKE DASH LIGHT WILL BECOME LIT AND ALL BRAKING ACTIONS HAVE DRASTICALLY REDUCED POWER. A AN AUDIBLE GRINDING NOISE IS OBSERVED FROM THE FRONT OF THE VEHICLE AND THE BRAKE PEDDLE HAS LITTLE TO NO RESISTANCE. A RESTART OF THE VEHICLE TEMPORARILY RESOLVE THE ISSUE, BUT THE ISSUE HAS REOCCURED NUMEROUS TIMES AND IS INCREASING IN FREQUENCY.

EMERGENCY BRAKE: E-BRAKE APPEARS TO ENGAGE ON ITS OWN AND THE BRAKE LIGHT INDICATOR COMES ON. THERE'S ALSO A GRINDING SOUND WHEN BRAKE IS PRESSED. GRINDING SOUNDS ONLY OCCURS WHEN THIS ISSUE COMES UP. EXHAUST MANIFOLDS: WAS NOTIFIED BY THE DEALER UPON A SERVICE INSPECTION THAT THERE WAS A SMALL CRACK IN THE EXHAUST MANIFOLDS. IS THIS A NORMAL THING? AND SHOULD THIS BE A RECALL ITEM AS IT COULD THROW OFF ANY SMOG CHECK TESTING. IN ADDITION HOW ABOUT THE EXHAUST IN THE CABIN ISSUE? MAYBE THEY USED TOO THIN OF A METAL FOR THE MANIFOLDS.

I HAVE A 2004 QX56 -- I'M HAVING THE SAME ISSUE WITH MY BRAKES. ALL OF A SUDDEN THE BRAKE LIGHT WILL COME ON AND WHEN YOU PRESS ON THE BRAKE YOU HEAR A SCARY LOUD GRINDING SOUND AND TRYING TO STOP IT REALLY TOUGH. IT FEELS LIKE THE ABS BRAKES KICKED IN --- IT HAS HAPPENED SEVERAL TIMES RANDOMLY. AS SOON AS I TURNED THE TRUCK OFF AND RESTARTED IT THE BRAKE LIGHT CAME OFF AND IT STARTED TO DRIVE LIKE NORMAL. BUT I HAVE HIT THE GRASS SEVERAL TIMES BC WHEN THIS FAILURE OCCURS YOU'RE LIKELY TO HIT SOMEONE IN FRONT OR, WITH A SUDDEN GRINDING STOP, SOMEONE HIT YOU FROM BEHIND. I TOOK IT TO THE SHOP AND THEY SAID IT WAS A BRAKE ISSUE. SO I REPLACED ALL 4 BRAKES AND ROTORS -- YET THE PROBLEM STILL HAPPENED!! I WENT BACK AND THEY SAID IT'S PROBABLY THE DELTA SENSOR AND IT'LL BE $1000 PLUS A FEW HUNDRED TO UPDATE THE COMPUTER TOO. THIS IS VERY DANGEROUS AND THE SCARY PART IS THERE IS NO WARNING-- IT JUST HAPPENS RANDOMLY. THIS IS SOMETHING INFINITI / NISSAN SHOULD FIX!!

STEPPED ON BRAKES AND PEDAL WENT ALL THE WAY TO FLOORBOARD WITH OUT STOPPING THE SUV. SUV FINALLY STOPPED ON SPEED BUMP A FEW FEET AWAY. LOOKED IN THE INTERNET, THERE ARE OTHER PEOPLE WITH SAME PROBLEM. THERE IS ALSO A COUPLE SUING NISSAN FOR THIS VERY PROBLEM. I THINK NISSAN SHOULD BE HELD RESPONSIBLE. THE PROBLEM I UNDERSTAND IS IN THE BRAKE POWER BOOSTER. IT SHOULD HAVE BEING RECALL.

WHILE TRAVELING ON THE HIGHWAY TO ANOTHER STATE, I ATTEMPTED TO STOP MY VEHICLE, AN 2004 INFINITI QX56, AS TRAFFIC SLOWED AND STOPPED. I PRESSED THE BRAKE PEDAL AND HEARD A CLICKING SOUND AND THE BRAKE INDICATOR LIGHT CAME ON AND THE VEHICLE WOULD NOT STOP COMPLETELY. THE PEDAL BEGAN TO GO TO THE FLOOR THEN BEGAN TO FEEL STIFF. I HAD TO SWERVE TO THE SIDE OF THE ROAD TO AVOID HITTING SOMEONE ELSE'S VEHICLE. ONCE I COMPLETELY STOPPED, I GOT OUT AND INSPECTED THE BRAKE FLUID LEVEL, AND THE BRAKES AND BOTH SEEMED TO BE FINE. I GOT BACK IN THE VEHICLE AND AFTER I TURNED THE IGNITION ON, THE BRAKE INDICATOR HAD WENT OFF AND THE PEDAL SEEMED TO BE WORKING FINE. I TRAVELED ON TO MY DESTINATION WITHOUT ANY OTHER ISSUES. ONCE AT MY DESTINATION, I HAD THE BRAKES INSPECTED AND THE REPAIR SHOP SAID THEY COULD NOT FIND AN ISSUE. THIS HAS HAPPENED SEVERAL MORE TIMES SINCE THIS INCIDENT, AND EACH TIME WHEN TAKEN TO A REPAIR SHOP, NOTHING CAN BE FOUND WRONG WITH MY BRAKES.

SERVICE BRAKES

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.
