What NHTSA says
Source: Office of Defects Investigation, as filedThe Office of Defects Investigation (ODI) analyzed complaint data provided by Nissan as well as complaints submitted to ODI from consumers. In total, there were 2 unique reports alleging inappropriate autonomous brake activation while driving. During PE12-022, Nissan identified a condition in model year (MY) 2013 Infiniti JX 35 that may result in inappropriate autonomous activation of emergency breaking by the Intelligent Brake Assist (IBA). According to Nissan, unique road environment anomalies can affect proper IBA operation and may cause IBA activation where it is not needed. ODI investigators were able to replicate the anomaly and found IBA interventions are extremely brief and may interrupt travelling speeds but do not stop the vehicle. Nissan developed a software countermeasure to address the condition and has initiated a customer satisfaction campaign to reprogram the Radar and Advanced Driver Assistance System (ADAS) control units on all affected vehicles. The bulletin was sent to dealers on August 10, 2012 and the owner letter mailing began on September 4, 2012. See the investigative file for copies of Nissan's bulletin and owner letter. The condition represents a low risk to motor vehicle safety and is adequately addressed by Nissan's service campaign. This preliminary evaluation is closed. The ODI reports cited above can be viewed at www-odi.nhtsa.dot.gov/owners/SearchNHTSAID under the following identification numbers (ODI Nos.): 10465524, 10466330
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 PE12022 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 PE12022 still open?
No. It closed on Nov 29, 2012 without a recall.
Which vehicles does PE12022 cover?
NHTSA opened it on 1 model year: 2013 Infiniti JX35. That is the scope of the inquiry, not a list of affected vehicles; a recall, if one follows, defines its own population by VIN.
