NHTSA's summary
As NHTSA's Office of Defects Investigation wrote it for Preliminary Evaluation PE12-022.
The 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.

What an NHTSA investigation is
NHTSA's Office of Defects Investigation (ODI) looks into possible safety defects in vehicles and equipment, often after owner complaints. An investigation usually starts as a Preliminary Evaluation, or as a Recall Query when it concerns whether an existing recall covers the right vehicles or fixes the problem, and ODI can upgrade it to a more detailed Engineering Analysis. A Defect Petition asks NHTSA to open an investigation, and Audit and Equipment Queries are administrative investigations into whether companies complied with federal vehicle safety requirements, such as reporting, recall and certification rules.
An open investigation is not a finding that a safety defect exists, and NHTSA can close one without a recall.
