2015 Nissan Leaf

FIRST SIGNS OF A PROBLEM WAS A YELLOW TRIANGULAR WARNING SIGN ON THE DASH WHEN I WAS CLOSE TO HOME, BUT NO DRIVING PROBLEMS. NEXT TIME STARTING THE VEHICLE AT HOME (ALL ELECTRIC VEHICLE) MANY LIGHTS LIT UP ON THE DASH AND THE BRAKE PEDAL ALMOST WENT TO THE FLOOR AS IT JERKED AND JUDDERED DOWN, AND A LOUD WARNING SOUND WAS EMITTED WHICH CONTINUED FOR QUITE AFTER A WHILE AFTER VEHICLE WAS SWITCHED OFF. THE CAR HAS BEEN FLAKY EVER SINCE, WITH EITHER A RED OR YELLOW WARNING SIGN LIGHTING ON THE DASH- OR NOTHING AT ALL. THE MOST SERIOUS EXPERIENCE, HOWEVER, WAS ON SEPTEMBER 15 (2020) WHEN I STARTED THE VEHICLE IN A PARKING LOT (WITH MY FOOT ON THE BRAKE - YOU CAN'T START WITHOUT THAT) - I PUT THE VEHICLE IN REVERSE AND THE CAR STARTED MOVING BACK EVEN THOUGH I STILL HAD MY FOOT FIRMLY ON THE BRAKE. I HAD TO USE A LOT OF EXTRA FORCE BEFORE THE VEHICLE FINALLY SLOWED DOWN AND STOPPED. THANKFULLY, THERE WERE NO OTHER VEHICLES OF PEDESTRIANS BEHIND ME. IN RESEARCHING THIS PROBLEM ONLINE, I HAVE FOUND DOZENS OF SIMILAR COMPLAINTS - WHICH IS QUITE AMAZING CONSIDERING SO RELATIVELY FEW NISSAN LEAFS ARE ON US ROADS.

WHILE I WAS ACCELERATING TO 60MPH FROM A STOP LIGHT ON US 287 AND ISABELLE ROAD IN BOULDER COUNTY, COLORADO, THE CAR CONTINUED TO ACCELERATE UNCONTROLLED TO OVER 70. ACCELERATOR PEDAL SEEMED TO NOT WORK AT ALL. I BRAKED AND SLOWED DOWN BUT IT WAS FIGHTING THE MAXIMUM ACCELERATION. I TRIED PUMPING THE BRAKES AND KEPT SLOWING DOWN AND THE CAR LOST ALL ENGINE POWER AND SEEMED TO BRAKE ITSELF. I PULLED OVER TO THE SIDE AND TURNED OFF THE CAR. TURNED IT BACK ON AND ALL SEEMED NORMAL. I AM CONCERNED THAT OTHERS MAY PANIC IN THIS SITUATION AND NOT BE ABLE TO CONTROL THE CAR. THE 2015 NISSAN LEAF I DRIVE HAS 31,000 MILES ON IT NOW AND HAS HAD ALL UPDATES AND SERVICES.

CAR GOES INTO TURTLE MODE, LOSING ALL POWER. HAS HAPPENED A FEW TIMES, EACH TIME HAS BEEN COMING OFF A HIGHWAY OR HEADING UP A STEEP HILL AND THEN TRAVELING AT LOW SPEEDS. WHEN CAR IS TURNED OFF AND ON, CODES RESET. I HAVE A READER FOR THE OBD, IT IS SHOWING FAULT P2138 000A EV/ HEC ACC PEDAL POS SENS 1,2, ERR EVC-196. AS POWER IS COMPLETELY LOST, THIS COULD EASILY CAUSE AN ACCIDENT. ONCE RESET THE CAR ACTS LIKE NORMAL. EVERY INSTANCE HAS HAPPENED WITH A BATTERY STATE OF CHARGE OF OVER 30%. *TR

WHEN THE CAR IS POWERED ON, THE BRAKES DO NOT ENGAGE; THE CAR LUNGES FORWARD OR BACKWARD AS IF IN GEAR, DESPITE CONSTANT PRESSURE ON THE BRAKES. THE ONLY WAY TO STOP THE SUDDEN MOVEMENT IS BY THROWING THE CAR INTO PARK AGAIN. IT FIRST HAPPENED IN 2017, WAS SERVICED BY A LOCAL DEALER, BUT STARTED HAPPENING AGAIN IN 2019. CONTACTED NISSAN AND THEY SAY THERE IS NO RECORD OF THIS BEING A PROBLEM AND SUGGESTED I GO TO A DIFFERENT DEALER - I WILL NEED TO PAY TO HAVE THE CAR TOWED TO THE DEALER AS IT IS UNSAFE TO DRIVE.

I HAVE A NISSAN LEAF 2015 S. I PUT MY FOOT ON THE BRAKE AND PUT THE CAR IN REVERSE AND MY FOOT IS STILL ON THE BAKE AND THE CAR MOVES BACKWARD ANYWAY AND THERE IS NO WAY TO STOP THE CAR IF SOMEONE IS BEHIND THE CAR. THIS HAS HAPPENED MORE THAN SIX TIMES NOW THE LAST TIME WAS AT PUBLIX AND IF SOMEONE WAS WALKING BEHIND THE CAR THIS WOULD HAVE BEEN VERY BAD. I AM AFRAID TO DRIVE THE CAR IF THIS WOULD HAVE HAPPEN BEFORE OPENING THE GARAGE DOOR I WOULD HAVE RAN INTO THE DOOR. THE CAR WAS PARKED EACH TIME THIS HAPPEN.

BRAKES FAILED TO ENGAGE WHEN CHANGING FROM PARK TO REVERSE. FOOT WAS FULLY ON BRAKE WHEN CHANGING TO REVERSE. CAR LUNGED BACKWARDS ALMOST HITTING SOMEONE IN PARKING LOT. NO INDICATORS APPEARED BEFORE DRIVING VEHICLE. INCIDENT OCCURRED AGAIN LATER THE SAME DAY BACKING OUT OF GARAGE. ISSUE APPEARS TO BE RELATED TO SECONDARY BATTERY FAILING BUT THE BRAKE BOOSTER SHOULD BE ON PRIMARY POWER SYSTEM AND NOT ON SECONDARY.

OCCASIONALLY, BRAKES FAIL TO WORK PROPERLY WHEN APPLIED AT NORMAL (NOT ABRUPT) PRESSURE. THEN ANTI-LOCK BRAKES ACTIVATE. THIS ISSUES IS ALL OVER THE FORUMS, AND MANY HAVE EXPERIENCED THIS. EACH TIME THE CAR WAS BROUGHT IN, NISSAN SAYS THERE IS NO ISSUE. THEY RESET ALL THE LIGHTS AND RETURN THE CAR. WE HAVE PICTURES OF OF WARNING AND MAINTENANCE LIGHTS ON THE DASH INDICATING A MALFUNCTION WHEN THIS OCCURS.THEN IT COMES BACK A FEW DAYS, OR SOMETIMES A MONTH LATER.

TL* THE CONTACT OWNS A 2015 NISSAN LEAF. WHILE DRIVING APPROXIMATELY 25-30 MPH, THE ACCELERATOR PEDAL WAS DEPRESSED AND SEIZED IN POSITION AS THE RPMS INCREASED. THE CONTACT STATED THAT THE BRAKE PEDAL WAS DEPRESSED IN AN ATTEMPT TO SLOW DOWN THE VEHICLE FOR APPROXIMATELY THREE BLOCKS. FINALLY, THE ACCELERATOR PEDAL INDEPENDENTLY RELEASED AND THE CONTACT WAS ABLE TO SLOW DOWN AND STOP THE VEHICLE. THE CONTACT STATED THAT THE FAILURE RECURRED ONCE MORE THE SAME DAY. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. LUTHER NISSAN OF INVER GROVE (LOCATED AT 1470 50TH ST E, INVER GROVE HEIGHTS, MN 55077, (952) 479-4974) WAS CONTACTED BY PHONE AND AN APPOINTMENT WAS SCHEDULED TO HAVE THE VEHICLE DIAGNOSED, WHICH WAS STILL PENDING. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 25,000. PIIR=Y. *DT*JB
