2018 Nissan Leaf Complaint Log

THE CONTROL PANEL TOUCHSCREEN DISPLAY IN THE NISSAN LEAF (2018) HAS A DENIAL OF SERVICE VULNERABILITY THAT CAN BE USED TO LOCK UP THE SCREEN. ONCE LOCKED, THE TOUCH SCREEN CAN NO LONGER BE USED EVEN IF THE CAR IS TURNED OFF AND ON. THE ONLY WAY TO UNLOCK THE SCREEN IS BY REMOVING AND RE-INSERTING THE SD CARD CONTAINING THE MAPPING DATA. THIS SEEMS TO ARISE FROM THE SOS FUNCTIONALITY LOCKING THE TOUCHSCREEN AND NOT TURNING OFF WHEN THE CAR DOES. TO REPLICATE: 1. TURN ON THE CAR, VERIFY THAT NISSANCONNECT WITH SOS FUNCTIONALITY IS ENABLED BY CHECKING THAT THE LITTLE LIGHT ON THE SOS BUTTON IS LIT. 2. PRESS THE SOS BUTTON. 3. PRESS AND HOLD THE SOS BUTTON WHILE TURNING OFF THE CAR. 4. THE SOS CALL WILL LOCK THE SCREEN OF THE CAR, AND WILL STAY THAT WAY UNTIL THE SD CARD IS REMOVED AND RE-INSERTED. TRIED REPORTING THIS TO NISSAN, NO RESPONSE.

TL* THE CONTACT OWNS A 2018 NISSAN LEAF. THE CONTACT STATED THAT THEIR SPOUSE WAS DRIVING THE FAMILY VEHICLE AND WAS ABOUT TO COME TO A STOP WHEN ANOTHER VEHICLE CRASHED INTO THE CONTACT'S SPOUSE FROM THE REAR. THEY ATTEMPTED TO BRAKE HOWEVER, THE VEHICLE SLID UNTIL IT HIT CURB. THE AIR BAGS DID NOT DEPLOY. THE CONTACT'S SPOUSE WAS NOT INJURED. THERE WAS KNOW ONE ELSE IN THE VEHICLE WITH THE CONTACT'S SPOUSE. THE PERSON THAT CRASHED INTO THE REAR OF THE CONTACT'S SPOUSE WAS NOT INJURED. THEIR WAS NO MEDICAL ATTENTION NEEDED. A POLICE REPORT WAS FILED. THE VEHICLE WAS DEEMED TOTALED BY THE INSURANCE COMPANY. THE DEALER WAS NOT CONTACTED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 13,000.

WHILE DRIVING THE VEHICLE, WITHOUT WARNING THE CAR STOPPED ITSELF SIMULATING A "SLAMMING ON THE BRAKES" AFFECT. THERE WAS NO WARNING, THE CAR JUST STOPPED. AFTER THE CAR STOPPED, AN ERROR APPEARED ON THE SCREEN SAYING "POWER SUPPLY FAILURE. TO AVOID ACCIDENT, SERIOUS INJURY OR DEATH DO NOT DRIVE. CONTACT DEALER FOR SERVICE." THE CAR STOPPING SUDDENLY IS VERY DANGEROUS, IF THERE WAS ANOTHER CAR BEHIND ME, OR IF I WAS ON THE FREEWAY, I WOULD HAVE GOTTEN REAR ENDED.

THE VEHICLE'S BLIND SPOT DETECTOR TURNS OFF AT LOW SPEEDS POTENTIALLY PUTTING THE DRIVER AT RISK IF THE DRIVER DEPENDS ON THE BLIND SPOT DETECTOR. THE COLLISION AVOIDANCE SYSTEM IS UNRELIABLE. WHEN THE CAR IN FRONT SWITCHES LANES AND THERE IS A STOPPED CAR IN FRONT THE VEHICLE STARTS TO SLOW DOWN BUT RELEASES THE BREAKS ABOUT 50 FT FROM THE STOPPED CAR AND STARTS WARNING OF IMPENDING COLLISION. AND THE BREAKS ARE NOT APPLIED.

NISSAN LEAF WITH PRO-PILOT ASSIST PACKAGE. INTERMITTENTLY THE SYSTEM WARNING LIGHT FOR AUTOMATIC FORWARD EMERGENCY BRAKING AND/OR LANE KEEP ASSIST WILL FLASH INDICATING SYSTEM UNAVAILABLE. THIS HAS OCCURRED ON MULTIPLE OVASSIONS AND AT VARIOUS LOCATIONS. DEALER HAS BEEN UNABLE TO ISOLATE CAUSE OR EFFECT REPAIR. I ALSO HAD THIS HAPPEN ON A NISSAN SENTRA LOANER CAR THEY PROVIDED SO ISSUE MAY BE WITH SYSTEM AND NOT JUST THE LEAF MODELS

THIS ISSUE OCCURS WITH THE NISSAN E-PEDAL ENGAGED/ENABLED. IT HAPPENS INTERMITTENTLY AFTER DRIVING OFF. SYMPTOM REGENERATIVE BREAKING/E-BRAKE DOES NOT ENGAGE. VEHICLE COASTS. NO BLUE BARS LIGHT UP ON THE DASH TO INDICATE THAT REGENERATIVE BREAKING IS ACTIVE. BREAK PEDAL HAS BE BE ENGAGED FOR IT TO STOP. I HAVE REPRODUCED IT SEVERAL TIMES USUALLY AFTER VEHICLE HAS BEEN PARKED FOR A LONG TIME. CHARGE LEVEL BETWEEN 30-80%. ISSUE HAS BEEN REPORTED TO DEALER (10/23/18). WAITING FOR A RESPONSE.

I HAD INITIATED A CLAIM SOMETIME LAST YEAR ABOUT THE B PILLAR PLASTIC DOOR TRIM POSSIBLY BEING DAMAGED FROM THE SUN'S REFLECTION. NISSAN USA REFERRED ME TO THE LOCAL DEALERSHIP SINCE THEY CANNOT HELP ME. THEY SAID THAT IT'S NOT A DEFECT AND WE WOULD HAVE TO PAY FOR ANY DAMAGES THAT NEEDED TO BE REPAIRED (ABOUT $1000). I DON'T AGREE WITH THIS AS IT'S NOT AN UNCOMMON ISSUE FOR DOOR TRIMS TO MELT JUST LIKE IF THE HEAT FROM A HEAT GUN WAS APPLIED TO IT. THERE ARE QUITE A FEW PHOTOS ONLINE AND NOT JUST NISSAN. I HAVE NO CONTROL OVER WHERE THE SUN REFLECTS OR THE BUILDINGS THAT REFLECT THE SUN'S RAYS. I DON'T BELIEVE THAT I SHOULD BE HELD LIABLE FOR THIS, THE VEHICLE WAS USED AS INTENDED, AND THERE ARE NO INSTRUCTIONS ON THE MANUAL REGARDING THIS. THE CAR IS MELTING FROM THE SUN.

The contact owns a 2018 Nissan Leaf. The contact stated while driving on several occasions at various speeds with the cruise control activated, the brake pedal was depressed; however, the vehicle lunged forward. The contact related the failure to NHTSA Campaign Number: 23V494000 (Vehicle Speed Control). The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 100.

WHILE DRIVING FORWARD, THE VEHICLE SUDDENLY, UNEXPECTEDLY AND VIOLENTLY APPLIES THE BRAKES WITHOUT ANY DRIVER INPUT WHATSOEVER! THERE ARE NO OTHER VEHICLES OR PEDESTRIANS IN THE VICINITY AT THE TIME. THIS SUDDEN BRAKING PROBLEM BEGAN ON OR ABOUT 5/15/18 AND HAPPENED ON SEVERAL OCCASIONS AFTER THAT. TWICE WHILE ENTERING THE UNDERGROUND PARKING GARAGE AT AN OFFICE BUILDING AND TWICE WHILE DRIVING ON A CITY STREET. VEHICLE HAS BEEN AT THE LOCAL NISSAN DEALER FOR OVER A WEEK BUT NEITHER THE DEALERSHIP NOR THE MANUFACTURER APPARENTLY HAS ANY IDEA HOW TO FIX THE PROBLEM. THEY THINK THAT THERE IS A FAULT IN THE AUTOMATIC EMERGENCY BRAKING SYSTEM. THE SERVICE MANAGER TOLD ME THAT OTHER INSTANCES OF THE SAME ISSUE HAVE BEEN REPORTED TO NISSAN. THE SALESPERSON INDICATED THAT THERE WERE 4 OTHER SIMILAR CASES AT THEIR DEALERSHIP ALONE.THEY ALSO WILL NOT LET US TAKE THE VEHICLE HOME WITHOUT SIGNING A RELEASE OF LIABILITY DOCUMENT. THE OBVIOUS CONCERN IS THAT THE EMERGENCY BRAKING SYSTEM WILL AGAIN RANDOMLY ACTIVATE WHILE TRAVELING AT A HIGHER SPEED AND CAUSE AN ACCIDENT RESULTING IN SERIOUS PROPERTY DAMAGE AND INJURIES!

WHEN THE BRAKES ARE APPLIED MODERATELY AT AROUND 40MPH TO SLOW DOWN, AND IF A WHEEL GO ON TOP OF SOME BUMPS OR POT HOLES, CAR SEEMS TO LOOSE BRAKING POWER, BRAKE PADEL DROP ABOUT 1 INCH, HAVE TO PEDAL HARD TO GET THE BRAKES BACK. AT ONE TIME I SAW A MESSAGE ON DASHBOARD "NOT AVAILABLE" WHICH I WAS NOT ABLE TO READ AND CONFIRM, AS THIS HAPPENED IN A PANIC SITUATION. THIS IS OCCATIONAL BUT HAS HAPPENED TO BE 4 - 5 TIMES NOW. MY GUESS IS CAR TRY TO APPLY REGENERATIVE BRAKES FIRST, IF THAT CANNOT WORK DUE TO EXCESSIVE, BUMP / POT-HOLE ON THE ROAD, IT GIVE UP, AND AS A RESULT, CAR LOOSE BRAKING POWER FOR 1-2 SECONDS. THIS 2 SECONDS CAN BE LIFE AND DEATH IN AN EMERGENCY BRAKING SITUATION. I TOOK THE CAR TO DEALER, AND THEY SAID, NO ISSUES FOUND. THIS PROBLEM IS HARD TO REPRODUCE, BUT CAN BE REPRODUCED. THIS HAPPENED IN LOCAL ROADS WITH 45MPH SPEED LIMIT. ONE TIME WHEN THERE WAS ROUGH ROAD DUE TO CONSTRUCTION. ANOTHER TIME WHEN ONE TIRE WAS GOING ON TOP OF ROAD DIVIDERS WHICH ARE ABOUT 1 INCH TALL AND 1 FOOT APART, IT HAD MANY OF THESE NEXT TO EACH OTHER, WHEN I WAS APPLYING BRAKE.

THIS NISSAN CAR IS EQUIPPED WITH FEATURES NAMED, PRO-PILOT ASSIST (PPA), INTELLIGENT CRUISE CONTROL (ICC) AND EMERGENCY BRAKE ASSIST (EBA). WHEN ENGAGED, IT IS SUPPOSED TO KEEP LANES AND FOLLOW DISTANCE IF THERE IS A CAR IN FRONT. WHEN THE CAR IN FRONT IS STOPPED THIS CAR IS SUPPOSED TO STOP AS WELL. PPA WHEN ENGAGED, IF THERE ARE GOOD ROAD MARKINGS, WILL SHOW A GREEN STEARING ON THE DASH BOARD, TO SHOW THAT CAR CAN STEER IT SELF. HOWEVER IF THERE IS A CAR STOPPED IN FRONT ON THE SAME LANE (EX. STOPPED FOR A RED LIGHT), THIS CAR DO NOT DETECT THAT THERE IS A CAR STOPPED, AND KEEP GOING FORWARD UNTIL CRASH INTO THE STOPPED CAR, DRIVER HAVE TO INTEVENE TO STOP AT THIS TIME TO STOP. I TOOK CAR TO DEALER AND THEY SAID THIS IS NORMAL. THAT IS NOT WHAT NISSAN ADVERTISE. THIS BEHAVIOR IS QUITE DANGEROUS OF THESE CARS, AND MY EXPECTATION IS THE CAR NEED TO STOP IF THERE IS AN OBSTRUCTION IN THE ROAD, WHEN THE GREEN STEERING WHEEL ON DASH IS SHOWING THAT CAR IS DOING AUTO-STEER.
