2008 INFINITI QX56 Service Brakes Problems

There are times when driving under 50 mph brake light comes on and the brakes have goes out which cause me to do an emergency pullover turn off the truck for a few minutes and the brakes reset. This is very concerning for me. This has happened on a few occasions.

Occasionally Brake light turns on in my dashboard then my braking system loses hydraulic pressure and I have troubling braking till I turn car off then resets and goes back to normal but while brake light us on is very troubling and concerning? This has happened on many occasions since purchasing the car if I remember in 2018

I HEAR I PING SOUND LIKE A SPRING, THE BREAK LIGHT COMES ON AND I AM UNABLE TO STOP THE VEHICLE AS NORMAL. APPEARS THE VEHICLE IS ATTEMPTING TO SLOW DOWN BUT DOES NOT COME TO STOP AS IT NORMALLY SHOULD. ONCE I TURN THE VEHICLE OFF THEN BACK ON IT'S JUST FINE UNTIL IT RANDOMLY OCCURS AGAIN WHEN APPLYING THE BREAKS AND/OR WHEN THE VEHICLE IS IDLE AND THE BREAK LIGHT COMES ON. THIS ISSUE ONLY RESOLVED ITSELF WHEN THE VEHICLE IS TURNED OFF THEN BACK ON. IT IS EXTREMELY ALARMING AND COULD CAUSE AN ACCIDENT.

THE BRAKES ON MY VEHICLE HAS A STRANGE REACTION WHEN I BRAKE AT TIMES AND IS HESITANT TO STOP. IT DOESN'T HAPPEN OFTEN BUT IT'S SCARY. USUALLY AFTER I STOP THE VEHICLE, CUT IT OFF & CRANK IT AGAIN THE PROBLEM GOES AWAY ONLY TO DO IT AGAIN ON A LATER DATE. AFTER GOING ONLINE I FIND THAT MANY OTHERS HAVE EXPERIENCED THE SAME PROBLEM WITH INFINITI QX56 & NISSAN ARMADA'S. I'M SURE WHETHER OR NOT IT'S A ABS SENSOR MALFUNCTION OR WHAT BUT THANKFULLY IT HAVEN'T HAPPENED WHILE BEING IN HEAVY TRAFFIC BECAUSE I FEAR I'LL REAR END ANOTHER MOTORIST.

TL* THE CONTACT OWNS A 2008 INFINTI QX56. WHILE DRIVING VARIOUS SPEEDS, THE ABS WARNING INDICATOR ILLUMINATED AND THE VEHICLE DECELERATED AND STALLED. WHEN THE VEHICLE WAS RESTARTED, THE VEHICLE WAS ABLE TO OPERATE. THE VEHICLE WAS TAKEN TO PRIORITY INFINITI OF GREENBRIER (1812 GREENBRIER PKWY, CHESAPEAKE, VA 23320) TO BE DIAGNOSED, BUT THE CAUSE OF THE FAILURE COULD NOT BE DETERMINED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 132,000. THE VIN WAS NOT PROVIDED.

BRAKE LIGHT COMES ON WHILE DRIVING, WHEN PRESSURE IS APPLIED TO BRAKES UNDER 40MPH THERE IS A GRINDING NOISE AND THE BRAKES SKIP. YOU CAN TURN THE IGNITION OFF AND BACK ON AND SOMETIMES THE BRAKE LIGHT GOES OFF AND EVERYTHING IS FINE AND SOMETIMES IT IS NOT. THERE SEEMS TO BE NO RHYME OR REASON. SOME DAYS IT NEVER COMES ON AND SOME DAYS IT NEVER GOES OFF. AFTER RESEARCHING ONLINE IT APPEARS THAT IT IS AN ISSUE WITH THE COMPUTER MODULE AND A SOFTWARE UPDATE IS NEEDED. PLEASE FIX THIS. THE FIRST TIME IT HAPPENED IT WAS VERY SCARY! I WAS DRIVING WITH MY 3 KIDS AND THOUGHT THAT MY BRAKES HAD WENT OUT COMPLETELY. IT WAS MONTHS BEFORE IT HAPPENED AGAIN BUT NOW IT SEEMS TO BE AN EVERY DAY OCCURENCE.

MY WIFE WAS DRIVING HER 2008 QX56 AND WHEN SHE TRIED TO BRAKE HER FOOT WENT TO THE FLOOR AND SHE HEARD A GRINDING NOISE, SHE PUMPED AND PUMPED THE BRAKES BUT DID NOT NOTICE ANY MEASURABLE SLOWING DOWN OF THE VEHICLE. FORTUNATELY THERE WAS NO ONE IN FRONT OF HER AND SHE WAS EVENATUALLY ABLE TO SAFELY PULL INTO A PARKING LOT AND STOP THE VEHICLE. UPON MY RESEARCH THIS APPEARS TO BE A KNOW DEFECT. THE DEALERSHIP WHERE I TOOK THE CAR, DIAGNOSED IT AS A DELTA STROKE SENSOR DEFECT. UPON RESEARCHING THIS THERE APPEARS TO HAVE BEEN A CLASS ACTION SUIT AGAINST NISSAN/INFINITIE THAT THE PLAINTIFFS WON. IF THIS IS A KNOW DEFECT WHY HASN'T THERE BEEN A RECALL? MY WIFE COULD HAVE BEEN SERIOUSLY INJURED OR KILLED OR SHE COULD HAVE INJURED OR KILLED SOMEONE ELSE DUE TO THE CATASTOPHIC LOSS OF BRAKES. THIS IS NOT A WEAR AND TEAR ISSUE AND THEIR IS NO WARNING THAT IT WILL HAPPEN. YOU JUST LOSE THE BRAKES AND THE ABILITY TO STOP. THERE NEEDS TO BE A RECALL BEFORE SOMEONE DIES (IF THEY HAVE NOT ALREADY).

APPARENTLY AS ALL OTHER COMPLAINTS ARE SIMILAR WITH THE BRAKE LIGHT COMING ON AND AS I APPLY PRESSURE TO THE BRAKE TO STOP THE SCRUBBING AND SCRAPING SOUND IS UNBEARABLE, I'VE BEEN TOLD IT'S THE BRAKE BOOSTER IS BAD FOR INFINITI QX56. FIX THE PROBLEM IF EVERYONE IS HAVING THE SAME ISSUE, PLEASE BEFORE SOMEONE GETS KILLED. ALSO THERE'S AN EXHAUST LEAK WHICH YOU CAN TELL BY A FLICKERING NOISE WHEN YOU CRANK UP AND ACCELERATE.

DURING NORMAL OPERATION OF THE VEHICLE AND WHILE IN MOTION, THE ABS BRAKE LIGHT INDICATOR ON THE DASH CONTROL PANEL ILLUMINATES WHEN APPLYING THE BRAKES, WHICH CAUSE THE BRAKES TO SHAKE AND MAKE SCRAPING SOUND. AT THAT POINT THE BRAKES FAIL TO STOP THE VEHICLE IN A SAFE DISTANCE, INCREASING THE CHANCE OF A COLLISION. ABS BRAKE LIGHT CLEARS AND NORMAL BRAKE FUNCTIONS RETURN WHEN THE IGNITION IS TURNED OFF, THEN BACK ON.

WHEN ATTEMPTING TO STOP TWO TIMES IN THE PAST FEW MONTHS THE BRAKES SUDDENLY FAIL ALLOWING US NO ABILITY TO STOP THE CAR ALMOST CAUSING A SERIOUS WRECK. THE BRAKE PEDAL GOES ALL THE WAY TO THE FLOOR WITH THE BRAKE LIGHT (NOT ABS) ILLUMINATED ON THE DASH. EVEN THOUGH NISSAN CONSUMER AFFAIRS IS AWARE OF THIS PROBLEM THEY ARE NOT BEING ACCOUNTABLE OR HELD RESPONSIBLE FOR THIS SERIOUS CAR DEFECT. ACCORDING TO THE CLASS ACTION LAW SUIT (WHERE THERE ARE MANY OTHERS REPORTING THE SAME PROBLEM) THE PROBLEM IS WITH THE ACTIVE BRAKE BOOSTER AND VDC CONTROL UNIT. THEY RECOMMEND FOR ME TO PAY 2-3000 DOLLARS TO HAVE THE CAR FIXED FOR A MANUFACTURING DEFECT. GIVEN THE SEVERITY OF THIS DEFECT IN THE CORE BRAKE SYSTEM ACROSS BOTH NISSAN AND INFINITI CARS AND THE FACT THIS WAS TAKEN TO COURT THERE SHOULD BE A RECALL FOR A FAILING BRAKE SYSTEM.

JUST PURCHASED A USED 2008 QX56 WITH 118,000 MILES. 2 INCIDENTS: WHILE COMING TO A STOP, BRAKES FAILED AND BRAKE LIGHT CAME ON. DEALER SAYS LOW BRAKE FLUID SO THEY FILLED AND ALL SEEMED FINE. 3 DAYS LATER, COMING TO A STOP TRAVELING LESS THAN 30 MPH SAME THING. THE DEFECT CONTINUED AS I MADE MY WAY TO MY HOUSE A BLOCK AWAY. I CAN SEE WHY THIS ISSUE WOULD CAUSE AN ACCIDENT AND THE ISSUE IN NO WAY FELT LIKE A PIN CAUSING AN ISSUE WITH THE PEDAL AND BRACKET AS DESCRIBED IN RECALL LISTED. VEHICLE BEING TOWED BY DEALER TO DETERMINE CAUSE BUT FROM REVIEWING ALL THE COMPLAINTS HERE, THERE SEEMS TO BE 2 COMMON THEMES: A BRAKE DEFECT AND NISSAN NOT FIGURING IT OUT.

VEHICLE WOULD NOT STOP, AND THE BRAKE LIGHT CAME ON. THERE WAS A SPRING NOISE COMING FROM THE DASH. THE VEHICLE WAS TURNED OFF AND TURNED BACK ON AND THE PROBLEM WENT AWAY. FROM WHAT I HAVE READ ON LINE IT IS A FAULTY DELTA STROKE SENSOR. *TR

DURING THE FIRST TWO OCCURRENCES, WHILE ATTEMPTING TO ENGAGE THE BRAKE PEDAL TO SLOW DOWN, THE BRAKES APPEARED TO "OPEN UP" CAUSING THE VEHICLE TO THRUST FORWARD IN A SLIDING MOTION INSTEAD OF COMING TO A HALT. WHILE REPEATEDLY PUMPING THE BRAKE PEDAL, THE BRAKING SYSTEM APPEARED EXTREMELY "LOOSE" AND THE BRAKES WOULD APPEAR TO ENGAGE AND QUICKLY DISENGAGE. THE SPAN OF BREAKING FOR EACH OCCURRENCE LASTED ABOUT 200-300 FEET BEFORE THE VEHICLE WOULD EVENTUALLY COME TO A COMPLETE STOP. FOLLOWING BOTH OCCURRENCES, THE VEHICLE WAS TURNED OFF AND THE BRAKES APPEARED TO WORK PROPERLY AFTER RESTARTING THE VEHICLE. DURING THE THIRD OCCURRENCE, THE EXACT INCIDENCE DESCRIBED ABOVE OCCURRED WHEN TRYING TO BRING THE VEHICLE TO A COMPLETE STOP; HOWEVER, THE SPAN OF BREAKING LASTED ABOUT 400 FEET. WHILE CONSTANTLY PUMPING THE BRAKE PEDAL TO GAIN CONTROL OF THE VEHICLE, THE BRAKES WENT FROM BEING EXTREMELY "LOOSE" AND GOING TO THE FLOOR TO BECOMING EXTREMELY HARD AND NOT ENGAGING AT ALL. THE BRAKE PEDAL APPEARED TO HAVE LOCKED AND NO PRESSURE COULD BE APPLIED TO THE PEDAL. ONCE THE PEDAL LOCKED, THE VEHICLE CAME TO A GRADUALLY SLOW STALL AND EVENTUALLY STOPPED WITHOUT THE ABILITY OF APPLYING THE BRAKES. AS WITH THE PREVIOUS TWO OCCURRENCES, THE BRAKING SYSTEM WOULD APPEAR TO OPERATE PROPERLY AFTER RESTARTING THE VEHICLE. *TR

I APPLIED BRAKES WITH PLENTY OF LEAD TIME BUT THE QX56 FAILED TO BRAKE CAUSING ME TO REAR END ANOTHER SUV; I DID MINIMAL DAMAGE TO THE OTHER CAR BUT DAMAGED MY RADIATOR/FRONT-BUMPER/HOOD. I HAD A SIMILAR ABS ISSUE ABOUT A WEEK BEFORE AS DESCRIBED BY MANY FOR THE 2004-2006 NISSAN/INFINITY RECALL BUT I DIDN'T RESEARCH THAT RECALL UNTIL THIS CURRENT ACCIDENT. MY AIRBAGS DID NOT GO OFF. ON INITIALLY BREAKING IT SOUNDED LIKE THE ABS WAS GOING TO KICK IN BUT THE CAR KEPT MOVING FORWARD WITH NONE OF THE NORMAL PULSING ACTION THAT WOULD NORMALLY BE FELT WITH ABS AND NO REDUCTION IN SPEED AS THE BRAKE PEDAL WAS FULLY DEPRESSED. *TR

I WAS DRIVING DOWN THE ROAD WHEN MY BRAKES STARTED TO SKIP. I STOP MY VEHICLE AND PUT THE VEHICLE IN PARK AND THEN PUT IT BACK IN DRIVE THEN I WAS ABLE TO DRIVE AGAIN AS NORMAL. IT HAPPEN THREE MORE TIMES AFTER THAT. IT'S VERY DANGEROUS FOR THIS KIND OF ISSUE TO OCCUR IN TRAVEL WHILE DRIVING AT ANY RATE OF SPEED. I NEED THIS ISSUE LOOKED AT BY THE DEALER SHIP AT THEIR EXPENSE. *TR

TL* THE CONTACT OWNS A 2008 INFINITI QX56. THE CONTACT STATED THAT WHILE DRIVING APPROXIMATELY 10 MPH AND DEPRESSING THE BRAKE PEDAL, SHE NOTICED A VIBRATION IN THE PEDAL AND THE VEHICLE WOULD NOT STOP. THE BRAKE LIGHT, VDC AND THE ABS WARNING LIGHTS ILLUMINATED ON THE INSTRUMENT PANEL. THE FAILURE RECURRED SIX TIMES WHILE THE CONTACT WAS TRAVELING AT DIFFERENT SPEEDS. THE VEHICLE WAS TAKEN TO THE DEALER SIX DIFFERENT TIMES. THE TECHNICIAN STATED THE BRAKE BOOSTER AND THE MASTER VAC ASSEMBLY WOULD HAVE TO BE REPLACED. THE VEHICLE WAS REPAIRED HOWEVER, THE FAILURE RECURRED AND RESULTED IN THE CONTACT BEING INVOLVED IN A CRASH. THE VEHICLE WAS NOT FURTHER REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 48,670.

THE BRAKES ON MY 2008 INFINITI QX56 FAILED AT AN INTERSECTION TODAY, CAUSING ME TO GO THROUGH A STOP SIGN AT AN INTERSECTION. THE BRAKE PEDAL WENT TO THE FLOOR AND A SPORADIC GRINDING NOISE WAS HEARD AND FELT IN THE BRAKE PEDAL. THE BRAKE INDICATOR LIGHT WAS ILLUMINATED IN THE INSTRUMENT CLUSTER. THE VEHICLE COASTED TO A STOP. I PUMPED THE BRAKES, BUT HAD NO BRAKE PRESSURE. I PUT THE VEHICLE IN PARK, THEN TURNED IT OFF. WHEN I RESTARTED THE VEHICLE, THE BRAKE INDICATOR LIGHT WAS NO LONGER ILLUMINATED, AND THE BRAKES APPEARED TO BE WORKING AGAIN. I IMMEDIATELY TOOK THE VEHICLE TO MY INFINITI DEALER SINCE THIS IS MY PRIMARY FORM OF TRANSPORTATION AND I HAVE 3 YOUNG CHILDREN. THE DEALER INFORMED ME THAT THE FAULT CODE INDICATED MY VEHICLE HAD A FAULTY BRAKE BOOSTER, WHICH WOULD NEED TO BE REPLACED FOR APPROX. $1000 (PARTS AND LABOR). THEY INFORMED ME THAT ALTHOUGH THEY HAD SEEN MULTIPLE QX56'S WITH THIS PROBLEM COME INTO THEIR DEALERSHIP, NISSAN DID NOT HAVE A RECALL IN PLACE. I FIND THIS TO BE UNACCEPTABLE. I AM LUCKY NONE OF MY 3 CHILDREN WERE IN THE CAR WITH ME AT THE TIME, AND THAT NO ACCIDENT RESULTED FROM MY BRAKE FAILURE. *TR
