| Investigations Summary: | In April 2014, Nissan north America launched safety recall 14v-138 to address problems with the occupant classification system (OCS) algorithm in the following vehicles: model year (my) 2013-2014 Nissan altima, pathfinder, sentra and leaf; my 2013 Infiniti jx35; my 2014 Infiniti qx60 and q50; and my 2013 Nissan nv 200/taxi vehicles. According to Nissan, the OCS may not properly classify adult front passenger occupants and deactivate, or turn off, the passenger's frontal air bag for an adult occupant. Since the recall was launched, office of defects investigation (odi) has received 124 complaints alleging problems with the OCS after the recall repairs and/or other OCS related repairs were made by Nissan/Infiniti dealers. The majority of the complaints allege the passenger air bag status light stays on (I. E. , indicating passenger air bag is turned off) for adult front passengers. Some of the complaints state the dealers have made multiple repairs but the problem still persists. A recall query has been opened to investigate the effectiveness of the recall remedy (a software update) and whether any other OCS related problems exist in the recalled population.
