  Fuel level gauge system failure
  FUEL SYSTEM, OTHER:STORAGE:FUEL GAUGE SYSTEM

  In a March 5, 2012 letter to NHTSA, Nissan North America, Inc. (Nissan) submitted a Defect Information Report identifying a defect in the combination meter circuit board in approximately 8,120 model year 2003 through 2004 Infiniti M45 vehicles manufactured from March 7, 2002 through June 3, 2004 (Recall No. 12V-088). According to Nissan, heat generated by several components of the circuit board may cause solder cracks due to thermal shock.Open circuits created by the solder cracks may cause the fuel gauge to read higher than the actual amount of fuel remaining in the gas tank or always indicate full.Because of this condition, drivers may run out of fuel without notice, resulting in an engine stall without warning with no possibility of restart. 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 315 unique reports indicating an inaccurate fuel level reading while driving, including 61 that resulted in an engine stall incident (7.5 incidents per thousand vehicles).In addition, Nissan provided warranty data showing 2,525 claims for replacement of the subject component (31% claim rate).Nissan will begin owner notification in mid-April 2012.Owners of the recalled vehicles will be notified to take their vehicle to an Infiniti dealer, who will install a sub-amplifier in the combination meter to bypass the electric circuit and ensure accurate fuel level indication.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.): 10429412, 10427140, 10426741, 10424642, 10423199, 10418078, 10416519, 10414944, 10412053, 10408935, 10406834, 10406096, 10404206, 10404080, 10395207, 10392714, 10386134, 10380863, 10374719, 10373992, 10369584, 10365717, 10365428, 10356315, 10353972, 10351181, 10349252, 10348351, 10342961, 10342641, 10336272, 10329869, 10325399, 10324572, 10323996, 10323757, 10322403, 10320190, 10318987, 10317547, 10317273, 10317234, 10317030, 10308445.

  Non-deployment of Side Thorax Air Bags
  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

  SIDE AIR BAG NON-DEPLOYMENT
  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.
