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.

THE BRAKES STOPPED WORKING THIS MORNING WHEN THE TEMPERATURE REACHED 0F. PULLING OUT OF A PARKING SPOT ON LOW SPEED I SAW THE "BRAKE" AND "ABS" WARNING ICON ON THE DASHBOARD. WHEN I TRIED TO STOP BY PRESSING THE BRAKE PEDAL, THE CAR WOULDN'T STOP AT ALL, WHEN THE PEDAL WAS PRESSED ALL THE WAY, I COULD HEAR THE ABS ENGAGING, BUT IT STILL DIDN'T WORK. I WAS ONLY ABLE TO STOP USING THE EMERGENCY BRAKE. I DID NOT OBSERVE ANY OBVIOUS BLOCKAGE(SNOW OR OTHERWISE) ON THE BRAKES. LATER IN THE DAY, THE BRAKES STARTED WORKING AGAIN WHEN I WARMED UP THE CAR BEFORE OPERATING. BECAUSE I WAS NOT SURE OF THE CAUSE OF MALFUNCTION, I'VE SENT THE CAR TO THE DEALER TO BE SEEN.

UPON STARTING MY 2015 LEAF, WITH MY FOOT ON THE BRAKE, I WAS ABLE TO PLACE THE CAR IN REVERSE; IN SPITE OF THE BRAKE BEING DEPRESSED, THE CAR IMMEDIATELY BEGAN TO MOVE. WITH THE BRAKE PEDAL DEPRESSED TO THE FLOOR, THE CAR CONTINUED TO MOVE IN REVERSE, UNTIL I FRANTICALLY APPLIED THE EMERGENCY BRAKE. ALL DASH WARNING LIGHTS BECAME ILLUMINATED AND THE CAR MADE A GRINDING SOUND, WHEN I STEPPED ON THE BRAKE. THE TOW TRUCK DRIVER HAD TO PUT CAR IN REVERSE AND USE THE EMERGENCY BRAKE TO MOVE THE CAR INTO A TOWABLE POSITION. PER NISSAN, THE INTELLIGENT BRAKE CONTROL UNIT FAILED AND WOULD NEED TO BE REPLACED ALONG WITH THE ASSOCIATED HARNESS. NISSAN OFFERED TO PAY $5,500, LEAVING ME TO PAY $1,500 TO COVER COST OF REPAIR. THIS IS A SIGNIFICANT SAFETY CONCERN THAT THE VEHICLE CAN HAVE A CATASTROPHIC BRAKE FAILURE WHICH COMPLETELY DISABLES THE VEHICLE. I AM VERY FORTUNATE THE FAILURE OCCURRED IN AN AREA DEVOID OF ANY PEDESTRIANS AND CLEAR OF ANY MOVING OR PARKED VEHICLES. I EXPECT THAT IT WON'T BE LONG BEFORE SOMEONE IS SERIOUSLY INJURED BY THIS FAILURE.

I BROUGHT THE CAR IN FOR BRAKE SAFETY RECALL IN 2017. ON OCT 31ST, 2018 WITH 56,320 MILES THE BRAKES FAILED IN DRIVEWAY TWICE IN COLD WEATHER. ON NOV 1 THE BRAKES WERE WORKING AGAIN WITH WARMER WEATHER. I DROVE TO THE DEALERSHIP. RAN TESTS, FOUND NOTHING WRONG. I WAS TOLD IT WAS A LOW 12 VOLT BATTERY EVEN THOUGH I HAD REPLACED THE BATTERY 24 MONTHS PRIOR (NOW 3RD BATTERY IN 3 YEARS). I WAS CHARGED $388 FOR A NEW BATTERY. BUT I COULD NOT LEAVE THE DEALERSHIP. THE BRAKES FAILED AGAIN BEFORE I COULD LEAVE. I HAD THE TECHNICIAN TEST. HERE ARE NOTES HE WROTE: "BRAKES FAILED AGAIN IN SERVICE PARKING LOT. ADVISOR VERIFIED CONCERN. YELLOW ABS LIGHT, YELLOW BRAKE SYSTEM WARNING LIGHT AND VDC WARNING LIGHTS WERE ON. NO BRAKE PEDAL PRESSURE. PEDAL WENT TO THE FLOOR AND COULD HEAR AN ELECTRONIC CLICKING NOISE. HAD TO USE THE EMERGENCY BRAKE TO STOP VEHICLE. VEHICLE WAS IN READY MODE WHEN CONCERN HAPPENED. CAUSE: ELECTRONIC BRAKE CONTROL UNIT FAILING TO COMMUNICATE WITH OTHER CONTROL UNITS." $2500 FIX. NISSAN COVERED 80%, BILL WAS $553 WITH NO REFUND FOR THE 12 VOLT BATTERY.

BRAKE WARNING LIGHTS ON DASH MAY TURN ON AT STARTUP SOMETIMES, AND PRESSING BRAKES CAUSE GRINDING NOISE (LIKE ANTI LOCK ACTIVATED). LOCATED IN SAN JOSE, CA, WEATHER IS ABOUT 50-90 DEGREES F. NISSAN KEEPS ON SAYING THERE'S NO ISSUE, AND IT'S A $4K FIX TO REPLACE THE WHOLE BRAKE SYSTEM, AND WILL NOT LOOK AT THE ISSUE. HAVE GONE TO SEVERAL DEALERSHIPS, NO HELP.

I WAS DRIVING FOWN THE HIGHWAY AND THE CAR IN FRONT OF ME STOPPED. I WAS GOING 45 MPH. I WAS TWO CAR LENGTHS BEHIND HIM. I HIT THE BRAKES AND THE CAR WOULDN'T STOP. I THEN SLAMMED THE BRAKES AND THE CAR SLOWED DOWN, BUT I ENDED UP REAR ENDING HIM. IT FELT LIKE MY CAR WAS ON ICE, BUT THE ROADS WERE CLEAR. IT WAS 29 DEGREES OUTSIDE.

THE MORNING OF NOVEMBER 9TH, 2018 I ATTEMPTED TO START THE VEHICLE AFTER HAVING BEEN PARKED OVERNIGHT IN OUR GARAGE. WHEN I PRESSED THE BRAKE PEDAL, I DID NOT FEEL ANY RESISTANCE. AFTER PRESSING THE ON BUTTON, I FELT THE PEDAL RESIST AND VIBRATE. I HEARD A GRINDING SOUND FROM BEHIND THE PEDAL AND WARNING LIGHTS ILLUMINATED FOR BRAKES AND ESC. THE VEHICLE WOULD NOT START SO I HAD IT FLATBED TOWED TO THE NISSAN DEALERSHIP. THEY DETERMINED THE ELECTRONIC BRAKE CONTROLLER HAD FAILED AND REQUIRED REPLACEMENT. THE DEALERSHIP AND NISSAN JOINTLY COVERED THE COST OF THE REPAIR, TO THEIR CREDIT. I AM CONCERNED THIS COMPONENT COULD FAIL WHILE DRIVING AND RESULT IN A LOSS OF BRAKING FORCE, CREATING AN UNSAFE SITUATION.
