  WHILE DRIVING, AND WITHOUT WARNING, ABS BRAKE LIGHT COMES ON AND BRAKES HAVE SEVERE VIBRATIONS AND DO NOT STOP VEHICLE NORMALLY. PROBLEM GOES AWAY WITH RESTART BUT COMES BACK PERIODICALLY( 2-3 TIMES PER MONTH). DEALERSHIP IS AWARE OF PROBLEM BUT REFUSES TO ADDRESS IT BECAUSE IT IS TOO EXPENSIVE TO FIX. COST ESTIMATE IS $2000. THIS PROBLEM IS DOCUMENTED ON NUMEROUS WEBSITES AND IS LIKELY TO RESULT IN DEATH IF NOT ADDRESSED. VERY DANGEROUS SITUATION, NOTIFIED INFINITI WHO REFUSED TO FIX PROBLEM BECAUSE I HAD NOT DONE ALL MY SCHEDULED SERVICES AT THE DEALERSHIP - IN OTHER WORDS, BECAUSE I WASN'T A GOOD ENOUGH CUSTOMER THEY WERE UNWILLING TO REPAIR DANGEROUS BRAKING ISSUE. *TR

• 12/12/2013· SERVICE BRAKES

  THE FIRST INSTANCE OCCURRED IN AUGUST OF 2012. WE WERE TRAVELING ON THE HWY AND WERE REDUCING SPEEDS FROM 65 TO EXIT THE RAMP. UPON APPLYING THE BRAKES THE EMERGENCY BRAKE LIGHT CAME ON AND STARTED FLASHING. WHEN THE BRAKES WERE APPLIED A METAL ON METAL SENSATION OCCURRED, AS IF THERE WERE NO BRAKE PADS LEFT ON THE VEHICLE AND METAL WAS GRINDING. WHEN THE BRAKE WAS RELEASE IT STOPPED, BUT THE VEHICLE COULD NOT BE STOPPED BY USING THE BRAKES. WE HAD TO COAST INTO A PARKING LOT AND COME TO A COMPLETE STOP. THE VEHICLE WAS THEN PUT INTO PARK, SHUT OFF. THE EMERGENCY BRAKE WAS APPLIED AND RELEASED (IT WAS NEVER ENGAGED BEFORE). ONCE THE CAR WAS RESTARTED THE LIGHTS WERE OFF AND THE BRAKES WERE IN STANDARD, NORMAL WORKING CONDITION. THE SECOND INCIDENT HAPPENED IN MARCH OF 2013. THE INCIDENTS ARE NOW FOR FREQUENT AND HAPPEN MONTHLY. SEVERAL TIMES WE HAVE BEEN IN TRAFFIC ON THE HIGHWAY AND HAVE HAD TO BRAKE QUICKLY DUE TO ROAD WORK, TRAFFIC, ETC AND HAVE SLIMLY MISSED HAVING AN ACCIDENT. BECAUSE WE CANNOT REPLICATE THE INCIDENT ON DEMAND THE INFINITI DEALERSHIPS CLAIMS THEY CANNOT DIAGNOSE OR EVEN FIX THE PROBLEM. THE BRAKING SYSTEM IS UNRELIABLE AND HAZARDOUS. I HAVE DONE THE PROPER MAINTENANCE ON MY VEHICLE BY HAVING BRAKE PADS REPLACED WHEN NECESSARY BECAUSE I AM A RESPONSIBLE OWNER. AT ANY GIVEN TIME I HAVE 3 CHILDREN IN MY VEHICLE AND AM GROWING MORE AND MORE CONCERNED TO DRIVE MY CAR IF THE BRAKES ARE NOT RELIABLE. *TR

• 11/15/2019· UNKNOWN OR OTHER,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.

  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. THANKS *TR

• 10/16/2015· EXTERIOR LIGHTING,UNKNOWN OR OTHER

  I PURCHASED THIS VEHICLE DECEMBER OF 2014 AND WITHIN A MONTH I NOTICED CONDENSATION IN BOTH HEADLIGHTS. WHEN I WAS DRIVING MY VEHICLE HOME ONE NIGHT WITH MY 4 CHILDREN THE LIGHTS FLICKERED AND WENT OUT. I HAD TO PULL OVER AND I FLICKED THE LIGHTS ON AND OFF HOPING THEY WOULD TURN ON AND THEY CAME BACK ON AND WORKED. NOW EITHER HEADLIGHTS WORK AND TO REPLACE THE ASSEMBLY IS $1600 EACH SO RIGHT NOW I DO NOT DRIVE MY VEHICLE AT NIGHT. I TALKED TO INFINTI AND THEY STATED THERE WAS A DESIGN FLAW IN THE HEADLIGHTS AND SINCE THEN THEY HAVE BEEN REDESIGNED. I HAVE ALSO DONE RESEARCH ONLINE AND THERE HAVE BEEN SEVERAL COMPLAINTS ON THE HEADLIGHTS OF MY VEHICLE. NOW THE OTHER PROBLEM IS WHEN I'M DRIVING ON A BUMP OR POTHOLE MY VEHICLE SEEMS TO VEER OFF TO THE RIGHT AND STEERING WHEEL SEEMS TO LOOSEN UP AND IF YOU ARE GOING FAST YOU COULD LOSE CONTROL OF THE VEHICLE. LUCKILY I DON'T DRIVE FAST BUT NOTICE WITH ANY POTHOLE IT VEERS RIGHT AND I HAVE ALSO RESEARCHED THIS PROBLEM AND IT IS ALSO A COMMON COMPLAINT.

• 10/15/2019· ELECTRICAL SYSTEM,ELECTRONIC STABILITY CONTROL (ESC),SERVICE BRAKES

  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).

  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.

• 09/29/2012· SERVICE BRAKES

  WAS TRAVELING AT APPROX 40MPH IN DRY CONDITIONS ON A GOOD ROAD SURFACE AND APPROACHING TRAFFIC LIGHTS AT AN INTERSECTION. APPLIED THE FOOT BRAKE LIGHTLY AND IMMEDIATELY NOTICED THE BRAKE PEDAL TRAVEL WAS SIGNIFICANTLY INCREASED. GROANING & GRINDING NOISES EMANATED FROM FRONT END AND COULD BE FELT THROUGH THE BRAKE PEDAL. IT WAS AS IF THE ABS HAD ENGAGED EVEN THOUGH THE CAR WAS BRAKING GENTLY ON A GOOD, DRY ROAD SURFACE. GLANCING AT THE DASHBOARD I NOTICED THE BRAKE LIGHT WAS ILLUMINATED. RUNNING OUT OF STOPPING DISTANCE, I TRIED PUMPING THE BRAKES AND NOTICED A "RAPID POPPING" NOISE AS THE BRAKE PEDAL WAS TRAVELING BACK UP. BRAKE EFFICIENCY WAS SIGNIFICANTLY REDUCED BUT THE VEHICLE DID COME TO A STOP ALBEIT IN AN UNCONTROLLED AND DANGEROUS MANNER. AFTER TRAFFIC LIGHTS CHANGED, I PULLED OVER THE INTERSECTION TO STOP ON THE SIDE OF ROAD AND THE SAME PROBLEM RE-OCCURRED. THE PROBLEM VANISHED AFTER SWITCHING OFF THE ENGINE AND DESPITE TRYING FOR SEVERAL HOURS THE FOLLOWING DAY ON AN EMPTY ROAD; I COULD NOT REPRODUCE THE PROBLEM. INFINITI DEALER INVESTIGATED BUT FOUND NO DTC CODE AND STATED A KNOWN SOFTWARE PROBLEM WAS NOT THE CAUSE (VERSION WAS ALREADY UP-TO-DATE). DEALER WAS UNABLE TO REPRODUCE THE PROBLEM. FOLLOWING THAT FIRST INCIDENT, THE PROBLEM RANDOMLY RE-OCCURRED APPROXIMATELY 1 TIME EVERY 3 MONTHS - EACH TIME A STOP / RESTART OF THE ENGINE WOULD RESOLVE THE PROBLEM. TESTING BRAKE FUNCTION DURING SUBSEQUENT OCCURRENCES OF THE PROBLEM REVEALED THAT EMERGENCY BRAKE FUNCTION WAS SERIOUSLY DEGRADED AND OVERALL STOPPING DISTANCE INCREASED BY MORE THAN DOUBLE. IN THE LAST SEVERAL MONTHS THE FREQUENCY OF THE PROBLEM HAS INCREASED TO THE POINT IT NOW OCCURS SEVERAL TIMES A WEEK. THE PROBLEM APPEARS MORE FREQUENTLY DURING THE HOT / SUMMER MONTHS. *TR

• 09/14/2022· 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.

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.

  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.

  WHEN APPLYING THE BRAKES A GRINDING SOUND OCCURS. THE ABS WARNING COMES ON AND YOU REALLY DON'T HAVE CONTROL OF THE VEHICLE. IT IS REALLY SCARY. IT HAS HAPPENED A FEW TIMES BUT YESTERDAY WAS A VERY CLOSE CALL.

  I WAS ON MY WAY TO PICK UP MY KIDS ON A CLEAR SUNNY EVENING AND WAS DRIVING ON REGULAR DEBRIS FREE PAVEMENT. AS I APPROACHED A SOLID YELLOW LIGHT, I PRESSED THE BRAKES AND HEARD/FELT A PINGING SOUND AND THE BRAKES WOULD NOT STOP THE CAR. THE FRONT END OF THE CAR WAS GRINDING AND IT SOUNDED LIKE A LARGE SPRING WAS GOING TO BREAK. I PUMPED THE BRAKES WHILE SCREAMING AND COULD NOT GET THE CAR TO STOP. THE LIGHT TURNED RED AND I HAD TO BURN THROUGH IT, FORTUNATELY WITHOUT COLLISION. I CONTINUED WITH NO BREAKS FOR THE NEXT 5 MILES AND DID NOT USE MY ACCELERATOR. I BURNED THROUGH ANOTHER SOLID YELLOW LIGHT. EVENTUALLY THE CAR WAS GOING SLOW ENOUGH THAT I USED MY EMERGENCY BRAKE TO COME TO A COMPLETE STOP. I TURNED THE ENGINE OFF AND CALLED MY HUSBAND. HE CAME FOR ME AND DROVE THE CAR HOME WITHOUT EXPERIENCING WHAT I JUST DID. THIS SAME THING HAPPENED ON 09/28/2012, WHICH I FILED A COMPLAINT FOR. AFTER DOING INTERNET RESEARCH THAT NIGHT, I FOUND THIS IS A COMMON PROBLEM WITH THE QX AND ARMADAS AND WHEN THE ENGINE IS TURNED OFF, IT CAN RESET THE COMPUTER AND TEMPORARILY FIX THE PROBLEM. THE NEXT DAY, THE INFINITI DEALERSHIP FOUND AND REPAIRED ERROR CODES C1179 DELTA SENSOR AND C1189 BREAK BOOSTER AND RESET THE COMPUTER. IT WAS COVERED UNDER MY EXTENDED WARRANTY WITH A DEDUCTIBLE AND THEY ASSURED ME THIS WILL FIX THE ISSUE. THIS IS THE SECOND TIME I HAVE EXPERIENCED THIS VERY HELPLESS AND FRIGHTENING EVENT. THIS IS A SERIOUS PROBLEM THAT NISSAN MOTOR CORP NEEDS TO ADDRESS. IT IS A SAFETY ISSUE AND NOT A ROUTINE MAINTENANCE ISSUE. THERE NEEDS TO BE A RECALL BEFORE SOMEONE DIES. I FOUND HUNDREDS OF COMPLAINTS ALL OVER THE INTERNET AND A CLASS ACTION LAWSUIT FILED IN 2011 FOR THIS VERY SAME ISSUE. I AM VERY FORTUNATE THAT NO ONE WAS INJURED OR KILLED IN MY EXPERIENCES, BUT THE EXPERIENCE HAS LEFT ME NERVOUS EVERY TIME I PRESS MY BRAKES. *TR

  AS I WAS EXITING THE STORE PARKING LOT, I HEARD A PING SOUND WHILE I PRESSED ON THE BRAKES. MY CAR EVENTUALLY CAME TO A STOP AFTER SEVERAL PUMPS OF THE BRAKES. I TURNED THE ENGINE OFF AND AFTER A FEW MINUTES, I STARTED THE CAR AND PROCEEDED TO DRIVE LESS THAN A MILE AND LOST THE ABILITY TO BRAKE AGAIN AS I APPROACHED A RED LIGHT. THE CAR SOUNDED LIKE A LARGE SPRING WAS GOING TO BREAK AND I HEARD A RAPID POPPING SOUND WHILE TRYING TO PRESS ON THE BRAKES. THE FRONT END SOUNDED LIKE IT WAS GRINDING AND THE RED BRAKE LIGHT CAME ON. THE LIGHT TURNED GREEN AND THE CAR IN FRONT OF ME STARTED MOVING RIGHT BEFORE I GOT TO IT. I MADE A SHARP RIGHT TURN WITHOUT BRAKES AND COASTED MY CAR TO A STOP AT A GAS STATION. I TURNED OFF THE ENGINE AND CALLED A TOW TRUCK. I HAD IT TOWED TO THE BRAKE STORE SINCE THEY JUST REPLACE THE BRAKES A MONTH BEFORE. THEY DID A FULL INSPECTION, SEVERAL TEST DRIVES AND WERE UNABLE TO DUPLICATE THE PROBLEM. THEY SAID THE BRAKES WERE IN PERFECT ORDER. IT WAS A CLEAR SUNNY DAY AND THE ROAD WAS REGULAR PAVEMENT FREE OF DEBRIS. I THOUGHT I WAS NUTS AND THEN I THOUGHT THE BRAKE STORE WAS LYING TO ME. I HAD JUST DROPPED MY KIDS OFF. IF THAT LIGHT HAD NOT TURNED GREEN WHEN IT DID, I WOULD HAVE REAR ENDED THAT CAR GOING 30 MPH. IT WOULDN'T BE UNTIL JUNE 2013 WHEN I REALIZED THAT THIS IS A COMMON ISSUE WITH THE QX AND ARMADAS AND IS NOT A PROBLEM WITH THE BRAKES RATHER WITH THE BRAKE BOOSTER AND DELTA S SENSOR. I AM FILING ANOTHER COMPLAINT THAT WILL BE DATED JUNE 6 2013. IF THIS PROBLEM IS NOT ADDRESSED BY NISSAN MOTOR CORP, SOMEONE IS GOING TO BE SERIOUSLY HURT OR COULD DIE. THIS WAS AN EXTREMELY FRIGHTENING AND HELPLESS FEELING. I KEEP MY CAR IN GREAT WORKING ORDER AND MAINTAIN IT AS IT SHOULD BE. THIS IS NOT A ROUTINE MAINTENANCE THING; THIS IS A SERIOUS SAFETY ISSUE THAT NISSAN NEEDS TO ADDRESS! *TR

  I WAS DRIVING WITH MY FAMILY IN THE CAR AND EXITING OFF THE HIGHWAY. WHEN TRIED TO STOP FOR APPROACHING TRAFFIC MY BRAKE WARNING LIKE CAME ON THE BRAKE PEDAL BECAME UNRESPONSIVE. AS I PRESSED THE BRAKES I COULD HEAR A BROKEN SPRING KIND OF SOUND AND IT FELT LIKE THE ABS SYSTEM WAS TRYING TO KICK ON. THE CAR DID SLOW BUT THE BRAKES WERE AT ABOUT 20%. TO AVOID HITTING THE APPROACHING CARS I HAD TO SWERVE OFF THE ROAD. WE WERE ABLE TO GET THE CAR TO A STOP BUT CLEARLY WOULD HIT THE CARS IN FRONT OF ME IF I WERE NOT ABLE TO GET OFF THE ROAD. WHILE WE DID NOT HAVE A CRASH I DID NOTICE TWO LARGE SCRAPES ON THE RIGHT SIDE OF THE CAR FROM RUBBING AGAINST THE RAIL WHICH I DID NOT NOTICE TILL LATE THE DAY AFTER. AFTER TURNING OFF THE CAR THE BRAKES WORKED LIKE NOTHING EVER HAPPENED. WE TOOK THE TO A LOCAL DEALERSHIP THE NEXT MORNING AND WE TOLD THAT "YEA THAT HAS BEEN HAPPENING" WITH THAT MODEL. WHEN I SEARCHED THE INTERNET FOR THE ERROR CODE I WAS GIVEN (C1179) I FOUND ALMOST 200 HUNDRED PEOPLE WITH A SIMILAR STORY TO MINE. MY VEHICLE HAS BEEN DEALER SERVICED WITH EVERY RECOMMENCED SERVICE. WHILE I UNDERSTAND THAT CARS ARE MACHINES AND THEY DO FAIL, BRAKES FAILING LIKE THIS DUE TO A BAD SENSOR IS A DEATH WAITING TO HAPPEN. AS A LOYAL NISSAN/INIFINITI CUSTOMER I AM VERY DISAPPOINTED THAT THIS WELL DOCUMENT ISSUE HAS NOT BEEN PROACTIVELY ADDRESSED. FOR THOSE READING THIS AT THE NHTSA PLEASE UNDERSTAND THAT SOMEONE WILL DIE DUE TO ISSUE. REVIEW THE 16 CLAIMS ON YOUR SITE TODAY, IT IS JUST A MATTER OF TIME. LAWYERS WONT TOUCH THIS UNLESS YOU HAVE A SEVERE PERSONAL INJURY AND NISSAN WONT ACT TILL LAWYERS TAKE SUIT...YOU DO THE UNFORTUNATE MATH. NISSAN/INIFINITI - I JUST EXPECT MORE. *TR
