2006 Infiniti QX56 brake problems

SERVICE BRAKES

Brake Failure. The brake fails occasionally while driving on the streets or on the Highways without Waring. The brake pedal goes down to the floor, and grinding/hitting metal to metal sound is heard and vehicle brake control is lost. Experiences were traumatic; you swing left or right to avoid hitting another vehicle from behind or running a red light. The vehicle has been inspected by an independent mechanic, and the brake components: rotors, pads, drum, and fluid levels were ok, each time it occurs. The brake lights come off and on and each time, the mechanic finds no issues with the brake components. One dangerous aspect of these occurrences is that after the vehicle sits for a while, like 30 minutes to one hour, and you go back to driving the vehicle, it appears that the brakes readjust and starts working normally; it continues to work normally about a month, and out of nowhere without warning it fails again and readjusts later. I was about to take my daughter to college out of County, and she has a lot of luggage as she lives in the dormitory; we would not use this Infinity which is a large SUV that could have accommodated me, my daughter and my wife, because of fear of brake failure on the highway. We decided that we would have to use our small compact Lexus instead, but I would not be accommodated in the Lexus because of my daughter's much luggage; my wife and my daughter will make the trip without me. Please look into these break failures.

SUV WILL HAVE TROUBLE BRAKING, EMITTING A LOUD, GRINDING NOISE WHEN BRAKES ARE APPLIED. DIFFIULTY STOPPING. ALMOST CAUSED A WRECK TWICE NOW. ONCE VEHICLE IS TURNED OFF AND BACK ON, THE SITUATION SEEMS TO STOP. HAPPENS PERIODICALLY. FIRST TIME HAD BRAKES, ROTORS REDONE IN CASE THERE WAS AN ISSUE, THOUGH THERE DID NOT SEEM TO BE ACCORDING TO THE MECHANIC. HAS CONTINUED TO DO IT A FEW ADDITIONAL TIME. TOOK IT INTO INFINITI DEALER. WAS TOLD IT WAS THE BRAKE VACUUM BOOSTER. THIS ITEM HAS BEEN RECALLED ON OTHER 2004-2008 INFINITI QX-56 AND NISSAN ARMADAS. WAS TOLD THAT MY CAR WAS NOT ON THE 'RECALL' LIST.

I WAS DRIVING AT APPROXIMATELY 60 MPH ON A FREEWAY WHEN TRAFFIC AHEAD CAME TO A SUDDEN STOP. I PRESSED THE BRAKE PEDAL AND IT TRAVELED TO THE FLOOR AND I DID NOT FEEL THE CAR SLOW AT ALL. THE "BRAKE" DASH INDICATOR LIGHT CAME ON, AND I CONTINUED PUMPING THE BRAKE PEDAL TO TRY AND SLOW THE CAR. WHILE I CONTINUED PRESSING THE BRAKES, THE CAR STARTED SLOWING DOWN RAPIDLY ON ITS OWN AS IF IT WAS PRESSING THE BRAKES ON ITS OWN AND I COULD HEAR A LOUD GRINDING SOUND. I RELEASED THE BRAKE PEDAL AND CROSSED SEVERAL LANES OF TRAFFIC AS THE CAR WAS UNCONTROLLABLY SLOWING TO REACH THE SHOULDER. I CALLED MY HUSBAND TO TELL HIM WHAT HAD HAPPENED AND REMAINED ON THE SHOULDER WITH THE CAR RUNNING. MY HUSBAND MET ME ON THE SHOULDER AND DROVE THE CAR HOME. HE SAID THAT THE GRINDING SOUND WAS THE ABS ON IN A PERMANENT STATE, AND WOULD ACTIVATE DURING EVERY BRAKING UNLESS THE BRAKES WERE APPLIED EXTREMELY LIGHTLY. THE CAR WAS DRIVEN TO OUR DRIVEWAY AND TURNED OFF. SEVERAL HOURS LATER MY HUSBAND DROVE IT AGAIN. THE "BRAKE" LIGHT WAS OFF, BRAKING RETURNED TO NORMAL, AND ABS COULD BE ACTIVATED WITH HARD BRAKING AS USUAL.

WHILE IN MOTION THE BRAKE PEDAL FEELS LOOSE AND THERE IS A GRINDING NOISE. THE BRAKING POWER LOSES FUNCTION, THE RED BRAKE LIGHT TURNS ON AND YOU HAVE TO PULL OVER AS SAFELY AS POSSIBLE TO TURN OFF THE VEHICLE FOR IT TO RESET ITSELF. I ONLY LEARNED THAT IT WILL RESET ITSELF WHEN YOU TURN OFF THE VEHICLE AFTER THE FIRST TIME IT HAPPENED TO ME ON A STREET. SINCE THEN IT HAS HAPPENED ON SEVERAL OCCASIONS WHILE ON THE HIGHWAY AND FREEWAY. THE FIRST TIME IT HAPPENED WAS ABOUT 2 YEARS AGO AND MOST RECENTLY 1 WEEK AGO.

SERVICE BRAKES

I HAVE BEEN COMPLAINING ABOUT MY BRAKE LIGHT WARMING WHILE VEHICLE IS IN MOTION TO INFINITY FOR 13 YEARS TO INFINITY OF VANNUYS ( THE ONLY DEALER THAT SERVICES MY VEHICLE). WHY OLE THIS 6000 LB VEHICLE IS MOTION AND THIS SAFETY HAZARD OCCURS, DEPRESSING THE BRAKE PEDAL DOES. IT STOP THE VEHICLE PROMPTLY AS THE BRAKE SYSTEM SHOULD AND A LOUD METAL GRINDING NOISE IS PRODUCED. I HAVE HAD MY VEHICLE TOAD TO THE DEALER WITH THE SAME PROBLEM ON SEVERAL OCCASIONS AND ALL I AM TOLD IS THAT THERE IS NOTHING WRONG WITH THE VEHICLE. THIS OCCURS INFREQUENTLY AND OVER THE YEARS IT HAS BEEN OCCURRING MORE FREQUENTLY. WHAT IS MORE TERRIFYING IS THAT THIS IS A PUBLIC SAFETY HAZARD THAT IS KNOWN TO NHTSA AND NISSAN/INFINITY OF AMERICA AND NO RECALL HAS BEEN ISSUED OR THE MANUFACTURER HAS NOT BEEN HELD ACCOUNTABLE FOR FIXING THIS SAFETY HAZARD. THIS HAZARD HAS OCCURRED ON SEVERAL OCCASIONS OVER THE LIFE OF OWNERSHIP ( I AM THE SOLE OWNER OF THE VEHICLE). I HAVE MADE INFINITI OF VANNUYS AWARE OF THIS ISSUE AND IT WASN'T UNTIL RECENTLY THAT MY SERVICE ADVISOR COMMUNICATED WITH ME IF HOW ALARMED AND CONCERNED HE WAS WITH THE ISSUE AS HIS TECHNICIAN WAS TEST DRIVING THE VEHICLE AND THE BALEARIC LIGHT TURNED ON WHILE THE VEHICLE WAS MOVING AND MAKING THE METAL GRINDING NOISE AND NOT BEING ABLE TO BRAKE AS THE BRAKE SYSTEM IS INTENDED TO DO SO. I COMMUNICATED WITH CONSUMER AFFAIRS AT INFINITI AND WAS TOLD BY THEIR DEPARTMENT THAT THEY CANNOT DO ANYTHING FOR ME AS THERE IS NO RECALL ON MY VEHICLE AND THAT NISSAN:INFINITI IS NOT AWARE OF THIS MATTER. I MENTIONED TO THE REPRESENTATIVE THAT I HAVE BEEN ENTERTAINING THIS CONCERN WITH SERVICE ADVISORS OVER 13 YEARS AND THEY WERE FINALLY ABLE TO LISTEN TO MY CONCERNS: THIS IS UNACCEPTABLE, SPECIALLY AFTER READING ABOUT CRUZ V. MATHENGE | NO. B286067. MY FAMILY'S LIFE AND MY OWN HAVE BEEN IN JEOPARDY OVER 13 YEARS AND I NEED HELP.

WHEN I AM DRIVING (PRESSING THE GAS) AN INCONSISTENT RANDOM CLICKING NOISE THAT'S AFFECTING THE BRAKE SYSTEM AND USAGE IS HEARD. IT'S DIFFICULT TO ACCELERATE. IN THE PAST, I WOULD SIMPLY TURN OFF THE VEHICLE AND TURN IT BACK ON AND THE NOISE WOULD STOP. IT WAS DIFFICULT TO EXPLAIN AND SHOW TO ANY MECHANIC BECAUSE IT DOES IT RANDOMLY AND UNEXPECTEDLY, THEREFORE IT WOULD NEVER DO IT WHEN NEEDED. I WENT ON BECAUSE IT WASN'T OFTEN AT FIRST. NOW IT'S AT AN EXTREME LEVEL AS IF THE VEHICLE DOESN'T WANT TO DRIVE AND I COULD BE ON THE HIGHWAY (YOU CAN IMAGINE HOW SCARY THAT IS AT HIGH SPEEDS).

TRAVELING AT HIGHWAY SPEEDS THE EMERGENCY BRAKE LIGHT ILLUMINATED. I STARTED TO GET TO THE RIGHT HAND SIDE OF THE HIGHWAY AND SLOW DOWN. WHEN I WOULD DEPRESS THE BRAKES THERE WAS AN INCONSISTENT CLUNKING NOISE, IT WAS DIFFICULT TO BRAKE, ABS SYSTEM DIDN'T SEEM TO BE WORKING. WHEN THE BRAKES WERE NOT ENGAGED THE VEHICLE SEEMS TO BE DRIVING FINE. I WAS ABLE TO SLOW TO A STOP IN A PARKING LOT WHERE I PUT THE VEHICLE IN PARK AND PHYSICALLY ENGAGED THE EMERGENCY BRAKE. I THEN DISENGAGED THE EMERGENCY BRAKE AND THEN TURNED THE VEHICLE OFF. I GOT OUT AND CHECKED ALL OF THE BRAKES FOR VISIBLE DEBRIS AND DIDN'T SEE ANYTHING. I RETURNED TO THE VEHICLE AND STARTED IT. THE EMERGENCY BRAKE LIGHT WAS NO LONGER ILLUMINATED AND THE VEHICLE SEEMED TO BE BACK TO NORMAL.

I HAVE OWNED THE CAR SINCE IT WAS NEW. WHEN THE CAR IDLES FOR LONG TIME, HIGH TRAFFIC OR RUN IN A LONG DISTANCE, THE BRAKE LIGHT COMES ON, SLIP LIGHT AND THE BRAKES CHATTER AND STOPPING CAR BECOMES ALMOST IMPOSSIBLE. NUMEROUS TRIPS TO THE DEALER OVER THE YEAR HAS PRODUCED NO FIXES....REPLACED SENSOR, BRAKE BOOSTERS, BRAKE PADS, FLUID CHANGES, IN ESSENCE PRACTICALLY AN ENTIRELY NEW BRAKING SYSTEM WITH NO POSITIVE RESULTS. THIS IS MAJOR ISSUE!!! I CAN NOT BELIEVE THAT NOTHING HAS BEEN DONE, LIKELY BECAUSE IT CAN NOT BE REPLICATED ON DEMAND. SOMEONE WILL GET HURT AND THEN SOMEONE MIGHT LISTEN.

MY BRAKES SOMETIMES JUST GOES CRAZY!!! THE PETAL GOES TO THE FLOOR AND IT GRINDS AND IT IS COMPLETELY OUT OF CONTROL. IT ONLY GIVES ME ONE DATE BELOW BUT IT HAS HAPPENED MULTIPLE TIMES.

NHTSA complaint #11089843 — an unverified report by a vehicle owner.

SERVICE BRAKES

MULTIPLE TIMES THE BRAKES HAVE WENT OUT AND I HAVE BEEN UNABLE TO STOP THE VEHICLE. THIS HAS HAPPENED IN VARIOUS PLACES AND DURING VARIOUS CIRCUMSTANCES INCLUDING ON THE HIGHWAY AND CITY STREETS, IT HAS ALSO HAPPENED IN PARKING LOTS. THERE IS NO INDICATION, WARNING LIGHTS OR SIGNS WHEN THEY STOP WORKING,I FIND OUT WHEN I PRESS ON THE BACK AND IT MAKES A ODD SOUND ALMOST LIKE A SPRING AND A PULSATING/GRINDING FEELING WHEN I PRESS THE BREAK DOWN. NO INDICATOR LIGHTS COME ON WHEN THE BRAKES GO OUT. I AM UNABLE TO GET THE VEHICLE STOPPED DURING THIS TIME. THERE HAS BEEN NO SET REASON OR PATTERN FOR THE BREAKS GOING OUT, THEY JUST RANDOMLY STOP FUNCTIONING. NORMALLY WHEN THIS HAPPENS FOR THE PAST YEAR, AFTER I GET MY VEHICLE TO A COMPLETE STOP, I TURN THE VEHICLE OFF AND THEN BACK ON AND IT'S BACK TO NORMAL. HOWEVER THE MOST RECENT INCIDENT WAS ON 2/24/2018 AND THE BRAKES WENT OUT 4 SEPARATE TIMES EVEN WITH TURNING THE VEHICLE OFF. I FEARED FOR THE SAFETY OF MY CHILDREN IN THE CAR AND MYSELF SO THE VEHICLE WAS RETURNED TO MY HOUSE AND NOT DROVE AGAIN UNTIL 2 DAYS LATER. INFINITI WAS NOTIFIED OF THE PROBLEM AS WELL. I AM GREATLY CONCERNED THIS WILL END UP CAUSING A VEHICLE ACCIDENT AND INJURY TO MY CHILDREN, MYSELF OR ANYONE ELSE. WHEN THIS FIRST STARTED HAPPENING I HAD BRAKES AND ROTORS CHANGED BUT PROBLEM CONTINUED. THERE IS NO RHYME OR REASON FOR WHEN THEY GO OUT AND I HAVE NO CONTROL OVER STOPPING MY QX56. THIS IS VERY CONCERNING TO KNOW IT CAN HAPPEN AT ANYTIME!

BRAKES SUDDENLY MAKES GRINDING SOUND WHEN DEPRESSED THAT ALSO SOUNDS LIKE A LARGE SPRING IS ABOUT TO SNAP. THERE IS A LOSS OF BRAKING POWER AND THE BRAKE PEDAL GETS MUSHY. THIS HAS OCCURRED IN HEAVY STOP AND GO TRAFFIC NUMEROUS TIMES. IF THE VEHICLE IS TURNED OFF AND RESTARTED THE PROBLEM IMMEDIATELY DISAPPEARS. THE VEHICLE HAS NEW ROTORS/DISC AND NEW PADS INSTALLED BY THE DEALER. I AM IN FEAR FOR MY LIFE BECAUSE I NO LONGER TRUST THAT I WILL BE ABLE TO STOP WHEN DEPRESSING THE BRAKES. I HAVE CONTACTED THE DEALER AND THEY SAID I HAVE TO BRING IT IN WHEN THE PROBLEM IS OCCURRING.

SERVICE BRAKES

MY CAR HAS THE NOTORIOUS ISSUE THAT SEEMS A LOT OF NISSAN TITAN, ARMADA, AND QX56 HAS. WHEN DRIVING, ALL IF A SUDDEN BRAKE LIGHT WILL COME ON THE DASH. ALL OF SUDDEN, WHEN I PRESS IN MY BRAKES, IT STARTS TO MAKE NOISE AND LOSES ALMOST ALL POWER IN THE BRAKING SYSTEM. LIKE THE ABS IS NOT WORKING. WHEN I TURN THE CAR OFF AND BACK ON, IT GOES AWAY TEMPORARILY BUT WILL SOON HAPPEN AGAIN. I TOOK IT TO NISSAN, AND THEY SAY THEY COULDN'T DO ANYTHING ABOUT UNLESS IT'S MALFUNCTIONING. SO THE NEXT TIME IT HAPPEN, I RISKED EVERYTHING TO DRIVE IT FROM THE HIGHWAY TO THE DEALERSHIP WITHOUT TURNING THE VEHICLE AND OFF TO ENSURE THE ISSUE IS PRESENT WHEN AT THE DEALERSHIP. CAR HAD 75K MILES AT THE TIME. THEY THEN TOOK IT BACK AND DID SOME KING OF UPDATE OR FLASH AND EVERYTHING HAS BEEN WORKING FOR A COUPLE OF YEARS. WELL NOW IT IS BACK WHILE I WAS DRIVING MY NEWBORN TO THE CHILDREN HOSPITAL 3 HOURS AWAY. I HAD TO PUT THE CAR IN NEUTRAL ON THE HIGHWAY TO LET IT ROLL, TURN OFF THE CAR WHILE ROLLING, THEN START IT BACK UP FOR MY BRAKES TO WORK. THIS SHOULD DEFINITELY BY A SAFETY ISSUE AND RECALL TO BE FIXED. SO MANY REPORTED INCIDENTS HAVE BEEN REPORTED AND EVEN A LAWSUIT. NOW INFINITI WANTS ME TO PAY TO HAVE THE ISSUED FIX AGAIN EVEN THOUGH IT WAS TEMPORARILY FIXED FOR A COUPLE YEARS. I DON'T KNOW HOW MANY ACCIDENTS OR DEATHS ARE REQUIRED TO FOR NISSAN TO TAKE OWNERSHIP ON ALL THESE MODELS AND NOT JUST FOR WHOEVER WAS PART OF THE LAWSUIT.

THE BRAKES GET HARD AND CANNOT STOP QUICKLY. IT GRINDS AND HAVE TO PARK AND CUT THE ENGINE OFF FOR A FEW MINUTES THEN IT WORKS AGAIN. ALMOST CAUSED A FATAL ACCIDENT. THIS IS DEFINITELY A FACTORY DEFECT DUE TO LOTS OF OWNERS ON THE NET HAVING THE EXACT SAME PROBLEM. THERE IS NO INDICATION WHEN IT ABOUT TO HAPPEN. IT HAPPENED AT LEAST THREE TIMES SINCE BUYING THIS VEHICLE USED FOR MY WIFE. THIS PROBLEM HAPPENS ALSO WITH THE NISSAN ARMADA. CONTACTED THE MANUFACTURER AND THEY DON'T SEEM CONCERNED AT ALL. THEY SAYS TO BRING IT TO YOUR LOCAL DEALER ON MY OWN EXPENSE. THIS IS AN DESIGN PROBLEM DUE TO THE AMOUNT OF COMPLAINTS FROM CUSTOMERS. I AM CONCERNED ABOUT NOT ONLY MY FAMILY SAFETY BUT OTHERS.

WHILE TRAVELING ON THE FREEWAY AT ABOUT 60 MPH, TRAFFIC IN FRONT OF ME BEGAN TO SLOW. WHEN I APPLIED THE BRAKES, THE BREAK PEDAL ALMOST WENT TO THE FLOOR AND MADE A BANGING OR THUMPING NOISE. IT FELT LIKE THE ABS WENT OFF AND I ALMOST RAN INTO THE BACK OF THE CAR IN FRONT OF ME. THIS HAS OCCURRED MANY TIMES SINCE I HAVE OWNED THIS VEHICLE AND WHEN I TAKE IT TO THE DEALERSHIP THEY CANNOT FIND ANYTHING WRONG AND SUGGEST TO START REPLACING PARTS AT THE COST OF A FEW THOUSAND DOLLARS. THE MOST RECENT INCIDENT WAS YESTERDAY WHILE TRAVELING ON THE FREEWAY. AGAIN I HAD TO STOP SUDDENLY AS THERE WAS DEBRIS IN THE ROADWAY AND THE BRAKE PEDAL WENT TO THE FLOOR.

OH MY ... WHAT A BAD PROBLEM. AFTER IDLING FOR ABOUT 10 MINUTES WHEN IT WAS ABOUT 90DEGF OUTSIDE THE "BRAKE" LIGHT CAME ON ... THEN WHEN TRYING TO MOVE THE BRAKES WOULD NOT WORK. THEY HAD A VERY BAD VIBRATION IN THE PEDAL AND MADE GRINDING AND SPRING POPPING NOISES. EVEN THOUGH GOING SLOW (<30 MPH) THE CAR WOULD BARELY STOP. I CANNOT IMAGINE THIS HAPPENING AT HIGHWAY SPEEDS. VERY DANGEROUS. TURNING THE CAR OFF AND THEN BACK ON RESOLVED THE PROBLEM, BUT I AM VERY CONCERNED THAT THIS IS GOING TO HAPPEN AGAIN AT A VERY BAD TIME. THE BRAKE PADS AND ROTORS WERE CHECKED AND THEY ARE FINE. THERE NEEDS TO BE A DEFINITIVE FIX AND RECALL FOR THIS DANGEROUS ISSUE.

SERVICE BRAKES

THE CAR EMERGENCY BRAKE LIGHT CAME ON, THE VDC, AND SLIP LIGHT FLASHES AND THE CAR LOSES BRAKE POWER, FELT LIKE PADS WERE GONE BUT THEY WERE NOT. ONCE THE CAR WAS TURNED OFF AND BACK ON LIGHTS WENT AWAY AND BRAKES CAME BACK. WE HAVE HAD BRAKES REPLACED, AND PROBLEM CONTINUED. ALSO THE SERVICE ENGINE SOON LIGHT CAME ON AND A MECHANIC TOLD US WE NEEDED NEW CATALYTIC CONVERTERS AND THE SERVICE ENGINE SOON LIGHT IS STILL ON AND OFF. BRAKE ISSUE AND LIGHT COMING ON HAS HAPPENED NUMEROUS TIMES AND IT DOES NOT MAKE A DIFFERENCE WHERE OR WHAT SPEED. I HAVE BEEN DRIVING DOWN THE INTERSTATE, IN THE NEIGHBORHOOD, PARKED, ETC. IT IS HAPPENING MORE FREQUENTLY AND WE HAVE HAD IT CHECK OUT BY MULTIPLE MECHANICS AND THEIR DIAGNOSTICS ARE NOT PICKING UP ANYTHING THAT IS WRONG. I HAVE 3 SMALL CHILDREN AND FEEL LIKE I AM GOING TO HAVE A PANIC ATTACK EVERY TIME WE GET INTO THE CAR. WHY IS THERE NO RE-CALL YET?! IF YOU ARE CONSIDERING BUYING THIS CAR RUN AND DO NOT BUY!

MY INFINITY QX 56 TRUCK BRAKE PEDAL STARTS TO VIBRATE AND MAKE LOUD SPRING NOISES, NEXT THE VEHICLE WILL BEGIN TO PULSATE VIOLENTLY DURING BRAKING AND MAKE A LOUD GRINDING NOISE WITH AN EXTENDED BRAKING RESPONSE (NEARLY CAUSING ME TO CRASH INTO TRAFFIC AHEAD OR IN FRONT OF ME). THE VEHICLE DEFECTIVELY TURNS ON THE ABS AND BRAKE LIGHT WARNINGS IN THE DASHBOARD WHILE USING BRAKES TO STOP AT STOP SIGNS, RED LIGHTS, OR TO MAKE TURNS BEHIND OTHER TRAFFIC. THIS ACTIVATION IS RANDOM WITHOUT CAUSE OR OCCURRENCE. I AM TERRIFIED TO DRIVE MY INFINITY 2006 QX56. I HAVE EXPERIENCED MULTIPLE NEAR DEATH CAR ACCIDENTS. I HAVE BEEN DEALING WITH THIS PROBLEM FOR ABOUT A YEAR. WAS TOLD IT WAS THE BRAKES (CHANGED THEM), WAS TOLD IT WAS THE ROTORS (CHANGED THEM), WAS TOLD IT WAS THE MASTER CYLINDER (CHANGED IT) WITH NO RESOLVE. PROBLEMS STILL EXISTS. FINALLY, INFINITY ADMITS ITS A MALFUNCTION IN MY DELTA SENOR. MALFUNCTION TO ME SOUNDS LIKE A DEFECTIVE PART AND THAT IS NOT MY $1500 BULLET TO BITE!

WHILE ATTEMPTING TO SLOW MY VEHICLE , WITH 8 PASSENGERS, THE BRAKES STARTED TO ACT ERRATICALLY. THERE WAS NO WAY TO SLOW THE VEHICLE IN A CONTROLLED MANNER. EITHER THE BRAKING WAS TOO HARD OR TOO SOFT ALMOST LEADING TO A COLLISION. I TOOK MY VEHICLE TO THE INFINITI DEALER THAT I PURCHASED IT FROM NEW. THEY REPLACED THE BRAKE BOOSTER AT A COST OF OVER $900 DOLLARS. THIS WAS IN OCTOBER OF 2012. 10, 000 MILES LATER IN MAY OF 2014, THE EXACT SAME BRAKING ISSUE AGAIN HAPPENED WITH MY VEHICLE FULLY LOADED WITH PASSENGERS. I TOOK IT TO THE LOCAL NISSAN DEALERSHIP AND THEY ARE SAYING THAT THE SAME PARTS NEED TO BE REPLACED NOW AT A COST OF OVER $1400 . THIS IS A MAJOR SAFETY ISSUE AND IS IN NO WAY RELATED TO NORMAL MAINTENANCE.

WHILE SLOWLY DOWN FOR A RED LIGHT MY VEHICLE BEGAN TO LOSE BRAKING AND THERE WAS POPPING AND GRINDING NOISES COMING FROM THE BRAKES. LUCKILY THERE WAS NOT A CAR IN FRONT OF ME AND AS I WAS ABLE TO DRIVE ALONG THE CURB TO FINALLY SLOW THE VEHICLE AND LUCKILY STOPPED BEFORE BEING IN THE MIDDLE OF THE INTERSECTION . BACK IN 2010 INFINITI CHANGED OUT THE BRAKE BOOSTER AND DELTA SENSOR WHEN THIS SAME OCCURRENCE HAPPENED WITH THE BRAKING SYSTEM. NOW 4 YEARS LATER IT HAPPENED AGAIN WHICH MEANS THEY ARE STILL INSTALLING A FAULTY PART. IT IS AT THE DEALERSHIP NOW AND BECAUSE IT IS OUT OF WARRANTY THEY WILL NOT COVER THE $2100 JOB ALTHOUGH THEY ADMIT THIS IS A NORMAL OCCURRENCE IN THIS VEHICLE.
