The National Highway Traffic Safety Administration (NHTSA) has opened an investigation into model year 2013 Nissan Pathfinder and Infiniti JX vehicles.
NHTSA's Office of Defects Investigation (ODI) has received Vehicle Owner Questionnaires (VOQs) from five owners alleging incidents of transmission cooler line connection failure in in model year 2013 Nissan Pathfinder vehicles.
The owners allege that the failures caused a sudden loss of power from the transmission due to the loss of the transmission fluid.
ODI identified additional field experience in Early Warning Reporting field report data submitted by Nissan. In July of 2013 Nissan issued a Service Bulletin (NTB13-071) titled, '2013 PATHFINDER; CVT FLUID LEAK AT COOLER HOSE' to provide diagnostic and repair procedures to address a condition similar to that described in the VOQs.
On the same date Infiniti issued Service Bulletin ITB13-025 to cover the same condition in the sister Infiniti JX models. A Preliminary Evaluation has been opened to assess the scope, frequency and safety-related consequences of the alleged defect.
The VOQs associated with the opening of this investigation can be viewed online under the following identification numbers: 10509134, 10507077, 10499362, 10493701, and 10490959.
