2015 Nissan Leaf

BRAKES FAILED UPON STARTING THE CAR. MULTIPLE WARNING LIGHTS ON THE DASHBOARD (BRAKE, ABS, TRACTION CONTROL, AND BRAKE SYSTEM) RESULTING IN TOTAL BRAKE FAILURE - CANNOT STOP THE CAR WITH NORMAL BRAKING EVEN WHILE JUST PUTTING THE CAR INTO DRIVE/REVERSE FROM PARK. STARTED HAPPENING ~3 WEEKS AGO. THE ONLY THING THAT STOPS THE CAR IS THE EMERGENCY / PARKING BRAKE. IF PRESSING THE BRAKE PEDAL ALL THE WAY, JUST BEFORE HITTING THE FLOOR THERE IS A LOUD POPPING / GRINDING NOISE AND THE PARKING BRAKE (?) ENGAGES. THE FIRST TIME, TURNING THE CAR OFF/ON FIXED IT. WE TOOK IT TO OUR LOCAL NISSAN DEALER, THEY SAID "COULD NOT FIND THE ISSUE IN THEIR SYSTEM" AND SAID IT WAS A "FLUKE" AND WOULDN'T HAPPEN AGAIN. HAPPENED AGAIN A FEW DAYS LATER AND TURNING THE CAR OFF/ON DIDN'T HELP, AND THE CAR WAS STUCK IN OUR DRIVEWAY. TRIED REPLACING THE 12V BATTERY, WHICH FIXED THE ISSUE TEMPORARILY. HAPPENED AGAIN A FEW DAYS AFTER THAT AND HAD TO GET IT TOWED BACK TO NISSAN. *NOW* THEY FOUND THE ISSUE IN THEIR SYSTEM AND THINK IT'S THE "DRIVEN INTELLIGENT BRAKE UNIT" AND COSTS $2600+ TO FIX. THEY ALSO SAY THE "MAIN ENGINE HARNESS" MAY NEED TO BE REPLACED FOR SOME REASON AS WELL, COSTING ANOTHER $2400+. HAVE CONTACTED NISSAN USA, THEY TOLD ME THEY DON'T HAVE A RECORD OF THIS BEING A PROBLEM WITH LEAFS (EVEN THOUGH THERE ARE DOZENS OF COMPLAINTS ON HERE) AND REFUSES TO PROVIDE ASSISTANCE. THIS BRAKE SYSTEM IS *EXTREMELY UNSAFE* FOR THE DRIVER & PASSENGERS, AND EVERYONE AROUND IT. MY KIDS COULD HAVE BEEN NEAR THE CAR WHEN IT STARTED MOVING ON ITS OWN EVEN THOUGH I WAS PUSHING THE BRAKE PEDAL. NO ONE NEEDS TO DIE OR GET GRAVELY INJURED BECAUSE OF THIS FAULTY SYSTEM.

MY CAR WAS PARKED IN THE DRIVEWAY OF MY HOUSE. I TURNED IT ON LIKE I DO NORMALLY AND I THEN I SEE THE RED BRAKE WARNING INDICATOR LIGHTS AND THE ABS WARNING INDICATOR LIGHTS ON THE DASHBOARD. I DIDN'T THINK TOO MUCH OF IT AS I WAS RUSHING TO GET SOMEWHERE. MY DRIVEWAY IS SLOPED DOWN SO WHEN I PUT IT ON DRIVE, I HAD TO STEP ON THE BRAKES. I NOTICED IT DIDN'T WORK AS I DEPRESSED IT ALL THE WAY DOWN. THEN I QUICKLY USED THE EMERGENCY BRAKES SINCE MY CAR WAS SLOWLY ROLLING DOWN. MY CAR IS 3 YEARS OLD, HAS ABOUT 35,000 MILES AND HAS NEVER BEEN IN AN ACCIDENT. THIS WAS THE FIRST TIME THIS HAPPENED.

I WAS DRIVING IN SOMEWHAT HEAVY TRAFFIC IN AN URBAN SETTING AT 25MPH WHEN, UNEXPECTEDLY, I HAD GREAT DIFFICULTY APPLYING THE BRAKES TO STOP AT AN INTERSECTION. IT TOOK CONSIDERABLE EFFORT, INCLUDING SWERVING, TO AVOID HITTING THE VEHICLE IN FRONT OF ME, AND I PULLED INTO A PARKING LOT AS SOON AS I WAS ABLE, AGAIN HAVING GREAT TROUBLE STOPPING. THE LOSS OF CONTROL OF THE BRAKES FELT LIKE I WAS SKIDDING ON SNOW OR ICE, DESPITE THE FACT THAT IT WAS A FAIRLY WARM AUGUST DAY. THERE WAS AN ACCOMPANYING LOUD, UNPLEASANT SOUND COMING FROM THE BRAKES WHEN I STOMPED ON THEM. I HAD ALSO NOTICED THAT A NUMBER OF WARNING LIGHTS ON THE DASH HAD COME ON ALL AT THE SAME TIME WHEN THE PROBLEM STARTED. AFTER COMING TO A COMPLETE STOP IN THE PARKING LOT, I TURNED THE VEHICLE ON AND OFF MANY TIMES, AND EACH TIME, THERE WAS A LOW BUT CLEARLY AUDIBLE THRUMMING SOUND, PLUS A VIBRATION I COULD FEEL IN THE BRAKES. THE SOUND WAS PARTICULARLY SURPRISING TO HEAR, GIVEN THAT THE VEHICLE IS OTHERWISE AN EXTREMELY QUIET (100% ELECTRIC) VEHICLE. AFTER ATTEMPTING TO RESTART THE VEHICLE ABOUT TEN TIMES, I DECIDED TO LEAVE TO WAIT FOR AWHILE BEFORE ATTEMPTING TO START IT AGAIN. AFTER ABOUT 20 MIN., I STARTED THE VEHICLE WITHOUT TROUBLE AND CAUTIOUSLY DROVE IT HOME ON LARGELY EMPTY SIDE-STREETS.
