2004 Infiniti QX56

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.

WHEN DRIVING VEHICLE SUDDENLY MAKES A LOUD GRINDING SOUND AND ABS AND BRAKE LIGHT COME ON ON GAUGE. WHEN TRYING TO BREAK IT IS IMPOSSIBLE. IT WILL NOT STOP. THIS HAS HAPPENED MORE THAN 6 TIMES ALREADY. THANKFULLY I WAS NOT IN TRAFFIC OR COLLISION AND INJURY COULD HAVE HAPPENED. IN ORDER TO REGAIN CONTROL YOU HAVE TO TURN VEHICLE OFF TO RESET IT. THIS PROBLEM MAY CAUSE A SEVERE INJURY OR EVEN DEATH.

I HAVE AN 04 QX56 AS A DAILY DRIVER. I WAS LEAVING WALMART AS I PULLED OUT OF THE PARKING LOT I PULLED INTO THE TURN LANE TO ALLOW A CAR TO GO BY MASHED MY BRAKE AND IT STARTED JER KING LIKE SOMETHING WAS TRAPPED IN MY BRAKES. WE PULLED ON DOWN TO A LARGE PARKING LOT GOT OUT NOTICE THE RED BRAKE LIGHT WAS ON AND UNDER THE HOOD SOMETHING WAS CLICKING NEAR THE AIR INTAKE THING. IT DID IT THE ENTIRE RIDE HOME AS WE WERE 30 MINS FROM HOME WE JUST DRIVE SLOW. GOT IN IT TODAY FOR THE 1ST TIME WAS OK TIL ABOUT 45 MINS INTO TRIP LIGHT CAME BACK ON BRAKES STARTED DOING THE SAME THING. I HAVE READ MANY PEOPLE COMPLAIN OF THIS ISSUE. IF IT DOESN'T GET RECALLED THERE WILL BE A WRECK IN THESE VEHICLES! PLEASE MAKE NISSAN/INFINITI RECALLED THIS PART! I HAVE RESEARCHED IT AND THERE WAS A LAWSUIT FILED BUT IT DIDN'T MAKE THEM ADMIT THERE WAS AN ISSUE JUST MADE THEM PAY FOR OUT OF POCKET EXPENSES. I AM A STAY AT HOME MOM COLLEGE STUDENT MY HUSBAND JUST LOST HIS JOB DUE TO HEALTH REASONS. I CAN'T AFFORD TO PAY FOR THIS ISSUE! *TR

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!! *TR

I HAVE A 2004 QX56 AND LIKE MANY OF YOU, I MA HAVING THE SAME ISSUE WITH MY BRAKES. THE BRAKE LIGHT WILL COME ON AND WHEN I PRESS THE BRAKE THEIR IS A GRINDING SOUND AND IT IS VERY DIFFICULT TO STOP. I TURNED THE TRUCK OFF AND RESTARTED IT AND THE LIGHT WENT OUT AND YOU COULDN'T TELL THAT ANYTHING WAS WRONG. I TOOK IT TO THE DEALER AND WAS TOLD IT WAS MY ROTORS AND THEY "THINK" THE BRAKE BOOSTER. THIS IS A VERY SERIOUS PROBLEM AND NISSAN NEEDS TO BE HELD ACCOUNTABLE AND MADE TO FIX THIS ISSUE.! *TR
