EA09005 · Non-deployment Of Side Thorax Air Bags

Opened Apr 1, 2009 · Closed Apr 3, 2012

Status: closed (inferred from source dates) · Air Bags:side/window

The subject vehicles are equipped with seat-mounted, side thorax air bags for the driver and front passenger.This investigation revealed that faulty side air bag module electrical connectors located under the driver and front passenger seats can cause an interruption in the electrical circuit that will drop the input voltage below the specified range.As a result, the air bag warning lamp illuminates on the instrument panel and the affected side air bag becomes deactivated.In June 2009, Nissan conducted a service campaign to repair the defective air bag electrical connectors in the subject vehicles (both Infiniti Q45 and M45 models).In June 2010, Nissan sent a second notification concerning the 2009 campaign to owners of vehicles that have not been remedied.Nissan is now conducting a safety recall of the Q45 vehicles not remedied under the service campaign (approximately 1,349 vehicles; see NHTSA Safety Recall No. 12V-079 for further details).The M45 vehicles are not included in the recall; however, Nissan is re-notifying owners of M45 vehicles that were not remedied under the previous service campaign.See attached report for more information.A safety-related defect trend has not been identified in the Infiniti M45 vehicles at this time and further use of agency resources does not appear to be warranted.Accordingly, this investigation is closed.The closing of this investigation does not constitute a finding by NHTSA that no safety-related defect exists.The agency will monitor the issue and reserves the right to take future action if warranted by the circumstances.The ODI reports cited above can be reviewed online at www-odi.nhtsa.dot.gov/owners/SearchNHTSAID under the following identification (ODI) numbers: 10327196 and 10402282

PE08067 · Side Air Bag NON-DEPLOYMENT

Opened Dec 2, 2008 · Closed Apr 1, 2009

Status: closed (inferred from source dates) · Air Bags:side/window

THE SUBJECT VEHICLES ARE EQUIPPED WITH SEAT-MOUNTED, SIDE TORSO AIR BAGS FOR THE DRIVER AND FRONT PASSENGER.THIS INVESTIGATION HAS REVEALED THAT FAULTY SIDE AIR BAG MODULE CONNECTORS LOCATED UNDER THE FRONT SEATS CAN CAUSE AN INTERRUPTION IN THE ELECTRICAL CURRENT THAT WILL DROP THE INPUT VOLTAGE BELOW THE SPECIFIED RANGE.AS A RESULT, THE AIR BAG WARNING LAMP ILLUMINATES AND THE AFFECTED SIDE AIR BAG IS DEACTIVATED.THE RATES OF COMPLAINTS, FIELD REPORTS AND WARRANTY CLAIMS RELATED TO THE SUBJECT ISSUE ARE VERY HIGH.FOR EXAMPLE, NISSAN SUBMITTED 4,853 WARRANTY CLAIMS ON 3,551 DISTINCT SUBJECT VEHICLES OUT OF 13,836 TOTAL SUBJECT VEHICLES.ALSO, ANALYSES OF WARRANTY CLAIMS INDICATE AN INCREASING FAILURE TREND OVER TIME.THIS PRELIMINARY EVALUATION HAS BEEN UPGRADED TO AN ENGINEERING ANALYSIS (EA09-005) TO FURTHER STUDY THE ISSUE.
