I RECENTLY PURCHASED A 2011 NISSAN LEAF VEHICLE FROM A PRIVATE PARTY. I QUICKLY NOTICED THAT MY BATTERY CAPACITY WAS AT 5 BARS AND THE VEHICLE HAS 73300 MILES. I ALSO NOTICED THE EV SYSTEM WARNING LIGHT WAS ON. I TOOK THE CAR TO MY LOCAL NISSAN DEALER AND LET THEM KNOW THAT I WAS GOING TO NEED A NEW BATTERY BUT WANTED TO KNOW THE HISTORY OF THE VEHICLES BATTERY BECAUSE I BELIEVE THAT THE DEGRADATION OF THE VEHICLES BATTERY WOULD FALL INTO THE SEVERE CATEGORY AND BECAUSE THE VEHICLE WAS IN BETWEEN OWNERS AT THE TIME NO ONE TOOK IT IN FOR A BATTERY REPLACEMENT. CURRENTLY IN 2020 THE 2011 VEHICLE IS AT 5 BARS MEANING THAT IF THE BATTERY ONLY LOST ONE BAR IN THE LAST YEAR THE BATTERY WOULD HAVE TO HAVE LOST MORE THAN 50% CAPACITY WITHIN THE TIMEFRAME THAT IT WOULD HAVE BEEN COVERED UNDER THE 8 YR/100,000MILES EXTENDED WARRANTY. THEY WOULD NOT PROVIDE ME WITH ANY VEHICLE BATTERY INFORMATION ALTHOUGH THE REPRESENTATIVE OF THE DEALER DID CONFIRM THAT THE WARRANTY WOULD HAVE BEEN IN EFFECT LAST YEAR. THEY THEN QUOTED ME $6600 FOR A BATTERY REPLACEMENT. AFTER RESEARCHING I FOUND A LETTER FROM NISSAN WHICH STATES THAT THE VEHICLE WARRANTY WOULD BE EFFECTIVE FOR 2011 MODELS WITH IMPLEMENTATION STARTING SOMETIME IN SPRING OF 2013. NISSAN SO FAR IS NOT WILLING TO REPAIR THE BATTERY OR ASSIST IN THE REPAIR ALTHOUGH THE WARRANTY WOULD HAVE COVERED THIS ISSUE. THE VEHICLE HAS COME CLOSE TO TURNING OFF WHILE I'VE BEEN ON THE ROAD. I AM AFRAID OF MY CARS BATTERY DYING WHILE I'M ON THE ROAD. IT'S MY ONLY VEHICLE. *TR

2011 NISSAN LEAF, HAVE TAKEN IT MULTIPLE DEALERS AND DONE THE UPDATE(S) REQUIRED BY NISSAN, WHICH ACTUALLY MADE MATTERS WORSE, REGEN IS NOT WORKING LIKE HAD PRIOR TO THE P3227 UPDATE. THE BIGGEST ISSUE WITH THE NISSAN LEAF IS THE BATTERY CAPACITY AND ADVERTISED CLAIMS. CURRENTLY CHARGING 100% AND GETTING LESS THAN 60 MILES RANGE. THE WARRANTY APPARENTLY AFTER TWO CLASS ACTIONS IS 5 YEARS 60,000 MILES WHICHEVER COMES FIRST. ALL ANYONE AT NISSAN OR THE DEALERS CAN SAY IS TO WAIT UNTIL WE DROP THE 9TH BAR. BUT FROM WHAT THE CUSTOMER SERVICE REP TOLD ME, I NEEDED TO DROP BELOW 70% , WHICH ACCORDING TO MY CALCULATIONS I HAVE. BUT NISSAN DOES NISSAN MATH, EACH BAR IS WEIGHTED AND THE SOFTWARE UPDATE MADE ADJUSTMENTS THAT ARE MYSTERIOUS TO MOST. NISSAN MISREPRESENTED THE LEAF AND WITH THE POOR BATTERY CHEMISTRY FAILED TO DELIVER AS PROMISED, AND NOW THESE CARS ARE PRACTICALLY BEING GIVEN AWAY. NISSAN DOES NOT COOL THE BATTERIES PROPERLY AND THERE COULD BE A DANGER THAT THEY ARE NOT DISCLOSING. THIS NEEDS TO BE INVESTIGATED FURTHER BY NHTSA/DOT

I PURCHASED MY 2011 NISSAN LEAF IN SEPTEMBER OF 2012 FROM STADIUM NISSAN IN ORANGE, CALIFORNIA. I QUICKLY LEARNED THAT THIS VEHICLE WAS NOT BUILT FOR MY 69 MILE COMMUTE(4.9 MILES PER KWH), BUT WAS ABLE TO ADAPT AND MAKE IT WORK UNTIL A JOB CHANGE IN OCTOBER OF 2013. MY 10 YEAR OLD SON AND I WERE REAR ENDED SHORTLY AFTER OUR MOVE TO TURLOCK, CALIFORNIA. MY NISSAN LEAF HELD UP VERY WELL TO BEING REAR ENDED AT 45MPH BY A FULL SIZED CHEVY SILVERADO; AS I DROVE IT AWAY AND THE CHEVY WAS TOTALED. MY SON AND I BOTH RECEIVED CONCUSSIONS FROM THE ACCIDENT, AND UNFORTUNATELY HE IS STILL FACED WITH MEMORY LOSS. MY LEAF WAS TAKEN TO ALFRED MATTHEWS COLLISION CENTER FOR REPAIRS, AND SENT TO CENTRAL VALLEY NISSAN TO HAVE THE BATTERIES REMOVED AND REINSTALLED BEFORE AND AFTER THE BODY REPAIRS. THE REPAIRS TOOK MORE THAN 2 MONTHS TO COMPLETE, AND MY LEAF HAS NEVER BEEN THE SAME. MY LEAF WILL NO LONGER GET THE 69PLUS FREEWAY MILES THAT I DROVE BEFORE THE ACCIDENT, AND WILL NOW ONLY GET 40-50 CITY MILES PER CHARGE (3.8 MILES PER KWH). I HAVE TAKEN MY LEAF BACK TO CENTRAL VALLEY NISSAN AT LEAST 6 TIMES IN THE LAST 8 MONTHS, AND EVEN HAD ONE OF THE TWO NISSAN LEAF MECHANICS EVALUATE THE ISSUES. AAA WAS WILLING AND READY TO TOTAL MY LEAF BASED ON THIS DRASTIC PERFORMANCE ISSUE, BUT THEY WERE TOLD BY CENTRAL VALLEY NISSAN AND THE LEAF MECHANIC THAT MY LEAF IS PERFORMING WITHIN SPECIFICATIONS FOR A 2011 LEAF WITH 35,000 MILES. I FIND THIS HARD TO BELIEVE BASED ON YOUR EPA ESTIMATES OF 106 CITY / 92 HIGHWAY (I AM CURIOUS IF OTHER LEAF OWNERS KNOW THAT WHEN THEIR VEHICLE IS 3 YEARS OLD AND HAS 35,000 MILES; THEY WILL ONLY GET 40 MILES PER CHARGE). *TR

DP22005 · Pedestrian Alert Sounds

Opened Jan 27, 2023 · Closed Aug 7, 2023

Status: closed (inferred from source dates) · Electrical System:propulsion System

NHTSA received a petition on or about July 18, 2022, requesting that Federal Motor Vehicle Safety Standard (FMVSS) 141 be applied to all electric and hybrid vehicles operating in the United States. The petition can be reviewed at NHTSA.gov under ODI Number 11486072. FMVSS 141 establishes performance requirements for pedestrian alert sounds for motor vehicles. The standard applies to hybrid and electric vehicles that have a gross vehicle weight rating of 4,536 KG or less or are defined as low-speed vehicles. The standard became fully applicable to all such vehicles manufactured on or after March 1, 2021.On January 27, 2023, NHTSA opened Defect Petition (DP) 22-005 to evaluate the subject matter described in the petition. On June 24, 2023 and as supplemented on June 25, 2023, the petitioner notified NHTSA he was withdrawing his petition. The petitioner indicated that, based on his review of data, there is no justification for asserting potential benefits that could be derived from actions sought by my petition. Based on the petitioner's withdrawal, DP22-005 is closed. Closure of this DP does not represent a determination by NHTSA regarding the subject matter of the petition.

PE19015 · Front Occupant Classification System Mat

Opened Oct 9, 2019 · Closed Jun 1, 2020

Status: closed (inferred from source dates) · Air Bags; Air Bags:frontal; Air Bags:sensor:occupant Classification

Preliminary Evaluation (PE) 19-015 was opened as a result of Defect Petition (DP) 19-002 which alleged that model year (MY) 2011 and 2012 Nissan Leaf were affected by the same defect addressed in an earlier recall, NHTSA Safety Recall 16V-244, but were not included in the scope of that recall.NHTSA 16V-244 involved a defect in the Occupant Classification System, a system intended to suppress deployment of the passenger's frontal air bag under certain specific conditions. Although the DP19-002 analysis determined the allegation that earlier MY Leaf vehicles should have been included in 16V-244 was not founded, the Office of Defects Investigation nonetheless granted the petition and commenced this investigation into the 2011 and 2012 Leaf since OCS failures were reportedly occurring in these vehicles. Further details on DP19-002 can be found at NHTSA.gov.On October 25, 2019, ODI sent an information request letter to Nissan North America (Nissan) requesting pertinent information on the subject 2011 and 2012 Leaf. Nissan provided its response on December 13, 2019. ODI has reviewed the information Nissan provided as well as new reports submitted to NHTSA's Vehicle Owner Questionnaire database. Based on review of all available information, and at this time, ODI has identified evidence supporting that a total of 76 subject vehicles likely experienced a failure of the subject passenger seat OCS mat. The count represents an incidence rate of about 0.4% on subject vehicles that average 8 to 9 years in service.Consistent with Nissan's explanation of how the subject OCS was intended to function, ODI's review of the reports indicates that when an OCS mat failure occurs, two different warning indicators appear on the instrument panel. The warnings provide clear and unambiguous notice to occupants that an OCS problem has been detected, and the owner's manual provides further information regarding the meaning and consequences of the detected failure, as well as advice to seek service. Additionally the OCS will store a diagnostic trouble code to aid service technician diagnosis, and the occupant warnings remain present until the underlying failure has been corrected.In its responses to ODI, Nissan also provided its assessment of the alleged defect in the subject vehicles, stating that it does not believe that an unreasonable risk to safety exists. Nissan states that its assessment of failed OCS mats recently collected from the field showed that external factors (e.g., damage from foreign objects) were responsible for the failures, rather than a design or manufacturing defect. Nissan also cited clear visual warnings and low incidence rates occurring in comparatively older vehicles as factors in its determination that a recall was not warranted. Lastly Nissan noted that most of the complaints received for this issue involved a high customer expense for the cost of repair for the OCS system, which is consistent with ODI's observations. Nissan is apparently considering a reduction in repair part cost as a means to address the customer satisfaction aspect of these complaints.Based on the analysis conducted, this investigation will be closed. The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist. NHTSA reserves the right take additional actions if warranted by future circumstances.The 20 ODI numbers cited above can be reviewed at NHTSA.gov under the following identification (ODI) numbers:11176324, 11193091, 11286687, 11290303, 11152569, 11207486, 11180021(duplicate of 11103556), 11103556, 11196006, 11287002, 11101830, 11193208, 11256669, 11172159, 11282156, 11102456, 11123812,

DP19002 · Front Occupant Classification System Mat

Opened Aug 16, 2019 · Closed Oct 16, 2019

Status: closed (inferred from source dates) · Air Bags:sensor:occupant Classification

A defect petition (see DP19-002) was received July 23, 2019 alleging that the occupant classification system (OCS) sensor (mat) in model year (MY) 2011 Nissan Leaf vehicles is defective and affects the proper deployment of the passenger front air bag. The petitioner provided a list of potentially related NHTSA reports and noted a Nissan recall involving later MY Leaf vehicles with OCS defect. NHTSA is granting the petition and opening a preliminary evaluation in response, please see PE19-015.Since receiving the defect petition, the Office of Defects Investigation (ODI) has determined that the MY 2011 and 2012 Leaf share a common OCS design, both using the same sensor mat for passenger presence sensing. Starting in MY 2013, Leaf OCS was changed to a design using a different sensing system, one that did not use the mat present in prior model year, Nissan Leaf. While MY 2013-2016 Leaf vehicles were recalled for an OCS defect under recall 16V-244, a recall influenced by ODI investigation EA15-004, earlier MY Leaf vehicles were not included because they were not affected by the particular defect involved in that recall.ODI identified and reviewed 13 vehicle owner questionnaire (VOQ) reports in its database, one of which is a duplicate, involving MY 2011 and 2012 Leaf vehicles that allege a problem with the OCS. The VOQs indicate that an OCS warning light illuminated at which point the vehicle was diagnosed and it was determined the sensor mat was the cause of the OCS problem. Most of the VOQs also noted the high cost of repair, which apparently involves replacement of the passenger front seat, according to complainants. None of the VOQs allege a problem with the performance of the passenger air bag, an injury, or a fatality due to the failure of the OCS.During the evaluation of this petition, ODI did not request information from Nissan regarding the complaint data in its possession, and accordingly the manufacturer complaint counts shown above are marked as not applicable. ODI will request this information during the upcoming investigation.The ODI reports cited above can be reviewed at NHTSA.gov under the following identification (VOQ) numbers: 11234415, 11207486, 11196006, 11193208, 11180021, 11176324, 11172159, 11152569, 11123812, 11103556 (duplicate of 11180021), 11102456, 11101830, 11052546.
