2015 INFINITI Q50 Service Brakes Problems

My braking system completely failed while I was driving with no warning of sound or dash safety indicators. The only way I was able to stop my vehicle is by shifting into park while I was in motion. Two days prior to my car losing all ability to brake, my car was routinely serviced by the local dealership. All check points were green, including my brakes. The dealership towed my car back to the service center to inspect. The diagnostics came back as the break actuator unit (computer sensor) shorted which led to no communication to the brake control assist unit (computer sensor). This loss of communication between these sensors basically caused my brake functions to fail. I was fortunate to have been leaving a parking garage and not on the open road. This could have been a fatal incident. The repairs are $7000 of which Infiniti has only offered to cover $3000. This is a safety issue and a loss of faith with Infiniti as a vehicle manufacturer. There needs to be an investigation so no lives are lost. My vehicle is still not fixed.

Brake Pedal sinks to floor slowly at Red Lights. Randomly vehicle will yank seat belt back when abs module detects no brake fluid pressure once in a blue moon. This is because of the defective ABS module hydraulics leak internally from the factory. As brake fluid heats up the internal leak gets worse. Most likely check ball to pump or out valve leaking by. Model year 2015 for sure. I never got it covered under warranty because the problem starts out very random and takes a lot of time for it to always happen. Dealers will just say no problem found. ABS module cost $1k for me to buy at the dealer. Now I have brakes all the time again no thanks to a factory defect module randomly giving poor to no braking power. Internet forums of 2014-2016 have many people saying the same thing. Not the master cylinder, it is an internally leaking ABS module and will have no codes. Not happy about paying to replace a factory defective part.

PLACE THE CAR IN REVERSE TO BACK OUT OF A PARKING SPACE. WHEN I GOT TO MY STOPPING POINT I APPLIED MY BRAKES TO STOP TO SHIFT GEARS TO GO FORWARD. UPON PRESSING THE BRAKES THE VEHICLE WOULD NOT STOP AND CONTINUE TO ROLL BACKWARDS I PRESSED HARDER TO STOP THE VEHICLE IT DID NOT STOP IT ROLLED OVER A CURB AND BACKED INTO ANOTHER CAR BEFORE IT STOPPED. ONCE I TURNED OFF THE CAR AND RE-STARTED THE CAR AGAIN THE BRAKES WORKED PROPERLY. DAMAGE OCCURRED TO BOTH VEHICLES.

MY VEHICLE HAS AN OPTIONAL TECH PACKAGE THAT PROVIDES FORWARD BRAKING, LANE DEPARTURE AND BACKUP BRAKING. APPARENTLY WHEN I HIT A POTHOLE, THESE SAFETY FEATURES OCCASIONALLY TURN OFF. IV'E HAD THESE CAR FOR 4 1/2 YEARS AND BECAME AWARE OF THIS PROBLEM ABOUT 6 MONTHS AGO. I'M HAVE BECOME DEPENDENT ON THESE SAFETY ENHANCEMENTS AND NO-LONGER FEEL COMFORTABLE WHEN DRIVING. I HAVE COMPLAINED THE DEALERSHIP SINCE NOVEMBER 19 AND STILL HAVE NOT RECEIVED A POSITIVE RESPONSE ALL I WANT IS TO HAVE A WORKING SAFETY SYSTEM..

WHEN THE CAR HAD 8K MILES ON IT, THE FRONT ROTORS WENT BAD I.E. DEFECTED AND INFINITI DEALER FIXED THEM AND REPLACED THE FRONT PADS AS A WARRANTY ITEM. NOW AT UNDER 24K MILES, THE REAR BREAKS ARE GONE BAD BUT THE DEALER AND INFINITI CORP. ARE DENYING THEY'RE DEFECTED AND REFUSE TO FIX THEM. THIS IS MY 3RD INFINITI, I HAD BEFORE A 2008 G35S, AND 2013 G37S, I DRIVE MY CAR REGULARLY IN TOWN AND HIGHWAY, NO EXCESSIVE DRIVING, AND MY REAR BRAKES NEVER WENT BAD ON OTHER INFINITI CARS UNDER 24K MILES. I BELIEVE THE REAR BREAKS HAVE PROBLEMS JUST LIKE THE FRONT ONES DID AND THE DEALER CONSIDERED THEM DEFECTED ROTORS BASICALLY AND FIXED THEM AS A WARRANTY ITEM. THE DEALER RECOMMENDED ME TO REPLACE THEM FEW WEEKS AGO WHEN THE CAR WAS IN THE SHOP FOR SOME ELECTRICAL PROBLEM, BUT THE BREAKS DIDN'T MAKE ANY NOISE AT THE TIME AND I THOUGHT THE DEALER JUST WANTS TO MAKE SOME MONEY. BUT, STARTING YESTERDAY I HEARD THE GRINDING SOUND AND THAT'S WHEN I CALLED THE DEALER BACK AND ALSO TALKED TO INFINITI CONSUMER AFFAIR, AND THEY REFUSED TO COVER THEM.

FIRST OF ALL THIS IS THE SECOND INSTANCE FOR THIS, THE FIRST TIME IT HAPPENED THE DEALER DISMISSED AS THE DRIVE ASSIST BEHAVING NORMALLY. HOWEVER WHILE MY WIFE WAS TAKING OUR SON TO SCHOOL THIS MORNING 04-15-16, THE STEERING WHEEL DECIDED TO TURN TO THE RIGHT SUDDENLY AT 45MPH, LUCKILY MY WIFE WAS ABLE TO CORRECT FOR IT BY STEERING IN THE OPPOSITE DIRECTION. SHE THEN CALLED ME AND SAID THAT SOMETHING IS WRONG WITH THE STEERING OF THE CAR AND THAT IT KEPT WAS PULLING TO RIGHT HARD. I TOLD HER TO FIND A SAFE PLACE TO PULL OVER AND TURN THE CAR OFF AND THEN START IT AGAIN. AFTER SHE WAS ABLE TO STOP SOMEWHERE SAFELY SHE TURNED THE CAR OFF AND THEN RESTARTED IT AND THE STEERING SEEMED NORMAL. I HAVE EXPRESSED MY CONCERNS OF THE SAFETY OF THE DRIVE BY WIRE AND STEERING ASSIST TO THE DEALER WE BOUGHT IT FROM AND TO INFINITI CONSUMER AFFAIRS WHEN THIS HAPPENED THE FIRST WEEK OF OWNING THE CAR, NOW THAT IT HAS HAPPENED AGAIN HAVE NO CONFIDENCE IN THE SAFETY OF THIS CAR, ESPECIALLY WITH MY 3 YEAR OLD IN IT. I CAN NOT EXPRESS TO THE WORRY I GO THROUGH EVERY TIME THEY DRIVE THE CAR. I INTEND ON CONTACTING BOTH THE DEALER AND INFINITY CONSUMER AFFAIRS BUT I KNOW WHAT I CAN EXPECT FROM THEM, NEXT STEP IS CONTACTING A LEMON LAW LAWYER FRO FURTHER ADVICE.

FIRST INITIAL INCIDENT: AROUND SEPT/OCT OF 2015, I WAS DRIVING IN A FREEWAY WHERE THERE WAS A HEAVY TRAFFIC. CARS WERE RUNNING AT A SPEED OF 10-20 MPH. I WAS SLOWLY APPROACHING TO A STOP BY STEPPING ON MY BRAKE. THAT WAS WHEN MY BRAKE WOULD LOCK ON ME AND THE CAR WOULD NOT STOP TO MOVE FORWARD. LUCKILY SINCE I WASNT GOING FAST, I AVOIDED AN ACCIDENT WITH THE CAR IN FRONT OF ME. RECENT INCIDENT: HAPPENED JAN/FEB 2016, I WAS ON MY WORK'S PARKING LOT WHEN IT HAPPENED AGAIN. I HIT MY COMPANY WORK TRUCK IN THE REAR (MY CAR PRETTY MUCH GOT BURIED UNDER THAT TRUCK) AND CAUSED MY CAR TO HAVE A DAMAGE ON MY HOOD AND BUMPER. I REPORTED THIS INCIDENT TO INFINITI USA 3/1/2016, GREAT SERVICE BY THE WAY, TELLING THEM ALL MY INCIDENTS. I DIDNT REPORT ON MY INITIAL INCIDENT SINCE I THOUGHT IT WAS JUST A ONE TIME THING. WHAT IF I DROVE 70-80MPH ON THE FREEWAY AND THIS HAPPENED? MY LIFE'S AT A RISK WITH THIS VEHICLE. I DRIVE A LOT FOR WORK BUT THIS CANNOT KEEP HAPPENING TIME TO TIME. SO AFTER MY REPORT TO INFINITI, THEY OPENED MY CASE (WILL NOT SHARE MY CASE NUMBER) AND WILL SEND IT TO A INCIDENT SPECIALIST. I HAVEN'T REPAIRED ANY OF MY DAMAGE FROM THE MALFUNCTION YET BECAUSE I STRONGLY BELIEVE I AM NOT LIABLE FOR ANY OF THIS DAMAGE. I READ ONE OF THE COMPLAINTS ON NOVEMBER, 2016, AND THAT PERSON'S CASE GOT REJECTED. I AM GUESSING INFINITI DOES NOT WANT TO AGREE THEIR MALFUNCTIONS AND BLAME IT ON THE CUSTOMER? I AM AFRAID THAT SINCE I DO NOT HAVE A DASHBOARD CAMERA OR ANYTHING THAT WILL SUPPORT MY STORY, IT MAY BE REJECTED. BUT I AM WILLING TO ACT UPON THEIR DECISION IF IT DOES NOT RESOLVE THE WAY HOW IT SHOULD BE RESOLVED. HIGHLY CONCERNED ABOUT ANYONE'S SAFETY NOW DRIVING THIS VEHICLE AROUND.

I WAS DRIVING 2015 INFINITY Q50 (PURCHASED ON 02/28/2015) ON LEE ROAD, SHAKER HEIGHTS, OHIO 44120, WHICH HAD A FIRST SCHEDULED MAINTENANCE ON 09/14/2015 AT THE BEACHWOOD INFINITY DEALER. I STOPPED AT THE INTERSECTION OF LEE ROAD AND CHAGRIN BLVD. BEHIND A BLACK JEEP FOR WAITING TRAFFIC. I HAD MY CAR IN DRIVE AND MY FOOT FIRMLY ON THE BRAKE, ABOUT FEW SECONDS PASSED AND SUDDENLY MY CAR STARTED TO MOVE SLOWLY FORWARD WHILE MY FOOT WAS STILL FIRMLY ON THE BRAKE. AS MY CAR DID NOT STOP, I ATTEMPTED TO PUSH THE BRAKE HARDER AND TO AVOID REAR COLLISION WITH JEEP, I TURNED TOWARD SIDEWALK, IN A MOMENT MY CAR JUST TOOK OFF AT THE SPEED, HITTING FIXED OBJECTS ON SIDE WALK, MISSING SOME ON COMING VEHICLES AND BY GRACE OF GOD I MANAGED MY CAR AND CAME ON CHAGRIN BLVD. WITHOUT FURTHER INCIDENTS. I HAD MY DASH CAM ON WHICH HAS RECORDED THE INCIDENT. THIS INCIDENT OCCURRED ON 09/18/2015. AFTER FEW DAYS I NOTIFIED THE INFINITY AND THE COMPANY ISSUED A CLAIM # 20499682. AFTER SEVEN DAYS MR. TERRY MATT CLARK, INCIDENT INVESTIGATION SPECIALIST, NISSAN NORTH AMERICA INC. CALLED ME AND TOLD ME HE CAN NOT SCHEDULED THE INSPECTION IMMEDIATELY AND SCHEDULED ON 11/06/2015, DURING THIS TIME VEHICLE WAS RESTORED WITH THE DAMAGE OVER $22,000.00 WHICH I CLAIMED THRU MY AUTO INSURANCE. ON 11/16/2015 I RECEIVED THE LETTER FROM MR. CLARK, DENYING THE PROBLEM WITH THE CAR AND NOT RESPONSIBLE FOR ANY CLAIM.

ON NUMEROUS OCCASIONS WHILE IN MOTION AT VARIOUS SPEEDS THE VEHICLE WILL AUDIBLY ALERT, BRAKE, STEER, AND DEADEN THROTTLE RESPONSE. THESE ARE RELATED TO ENHANCED SAFETY FEATURES OF THE VEHICLE. THE PROBLEM IS THAT THESE OCCUR WHEN THERE IS NOTHING TO AVOID OR ANY DANGER PRESENT. THESE HAVE OCCURRED AT HIGH SPEEDS AND IN SITUATIONS WHERE THEY COULD HAVE CAUSED AN ACCIDENT. MY LOCAL DEALERSHIP BLAMED ALL ISSUES ON THE PLACEMENT OF AN EZ PASS TRANSPONDER. I FIND THIS TO BE COMPLETELY ABSURD. INFINITI CUSTOMER CARE WILL NOT ASSIST. I HAVE DISABLED ALL OF THESE SYSTEMS TO AVOID POTENTIALLY DANGEROUS SITUATIONS. I NOTE IN THE DATES THAT THIS OCCURED ON 10/10/15, HOWEVER THERE HAVE BEEN MULTIPLE INSTANCES. ON 10/10/15 THE VEHICLE STEERING HAD TO BE HELD AT 30-45 DEGREES TO THE LEFT TO KEEP THE VEHICLE IN A STRAIGHT LINE.

RECENTLY I WAS SITTING AT A STOPLIGHT ABOUT 3RD IN LINE BEHIND A FORD EXPLORER. I LIVE IN ATLANTA SO STOPLIGHTS ARE EXTRAORDINARILY LONG. I HAD THE CAR IN DRIVE OBVIOUSLY AND MY FOOT FIRMLY ON THE BRAKE. ABOUT 5 MINUTES INTO THE RED LIGHT MY CAR STARTS TO SLOWLY MOVE FORWARD WHILE MY FOOT WAS STILL FIRMLY ON THE BRAKE. THE MOVEMENT WAS SIMILAR TO IF THE BRAKE HAD BEEN RELEASED AND THE CAR WAS COASTING IN DRIVE. FORTUNATELY I LEFT SOME DISTANCE BETWEEN MYSELF AND THE EXPLORER IN FRONT OF ME, BUT OBVIOUSLY A MOMENT OF PANIC COMES OVER ME WHEN MY CAR IS MOVING FORWARD WITH MY FOOT ON THE BRAKE. I ATTEMPTED TO PUSH EVEN HARDER ON THE BRAKE WITH NO RESULTS, MY CAR IS STILL INCHING FORWARD CLOSER AND CLOSER TO THE EXPLORER IN FRONT OF ME. THE BRAKE FELT FIRM LIKE IT SHOULD BE WORKING. I HAD TO THINK FAST AND THEN SLAMMED THE GEAR SHIFT INTO PARK. THIS FINALLY STOPPED THE MOVING VEHICLE IN WHAT SEEMED LIKE ONLY MILLIMETERS IN TIME TO AVOID REAR ENDING THE SUV IN FRONT OF ME. THIS IS THE SECOND TIME THIS HAS HAPPENED TO ME WHERE THE CAR STARTS TO MOVE AT A PROLONGED STOP WHILE MY FOOT IS ON THE BRAKE. I'M GOING TO TRY TO REPLICATE THE INCIDENT IN A CONTROLLED SAFE ENVIRONMENT TODAY, BUT NEEDLESS TO SAY IT WAS A VERY SCARY MOMENT AND I'M TRULY WORRIED ABOUT THE SAFETY ON THIS VEHICLE.
