Nissan preliminary evaluation PE19015
Front Occupant Classification System Mat. NHTSA’s Office of Defects Investigation opened this preliminary evaluation about the frontal on 2 model years (2011–2012). Opened Oct 9, 2019, closed Jun 1, 2020 after 8 months without a recall. closed
What NHTSA says
Source: Office of Defects Investigation, as filedPreliminary 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,
A Preliminary Evaluation is the first formal stage: NHTSA has decided the complaints and other information it screened are worth a closer look, and asks the manufacturer for its own data on the condition. The summary is the agency’s own text from its investigation file, unedited; the opening and closing resumes with the full reasoning are on NHTSA’s site under this number.
What this means for an owner
Source: and what happens nextAn investigation is not a finding that a defect exists, and it puts no duty on anyone. NHTSA opens a Preliminary Evaluation when complaints and other reports suggest a condition worth asking the manufacturer about; it upgrades to an Engineering Analysis when the answers warrant testing; it closes either when it recommends a recall, when the manufacturer recalls on its own, or when no defect trend is found. The agency’s own goals are about four months for a petition, eight for a Preliminary Evaluation or a Recall Query and eighteen for an Engineering Analysis; many run longer.
This one closed without a recall. That means NHTSA found no defect trend it chose to act on at the time, or the manufacturer addressed the condition another way (a service campaign or a bulletin, which have their own pages). A closed file can be reopened if new reports arrive.

Common questions
Source: NHTSA Office of Defects InvestigationIs PE19015 a recall?
No. A preliminary evaluation is NHTSA asking questions, not a recall. A safety recall carries an NHTSA campaign number and a duty to repair for free; this one closed without one. Whether one particular vehicle has an open recall is a VIN question at nhtsa.gov/recalls.
Is PE19015 still open?
No. It closed on Jun 1, 2020 without a recall.
Which vehicles does PE19015 cover?
NHTSA opened it on 2 model years: 2011 Nissan Leaf, 2012 Nissan Leaf. That is the scope of the inquiry, not a list of affected vehicles; a recall, if one follows, defines its own population by VIN.
