2006 Infiniti G35 recalls

2 NHTSA recall campaigns list this model year.

  1. NHTSA 10V175000Apr 27, 2010Structure & Body134,215 vehicles

    Seats

    Nissan is recalling certain model year 2005 through 2007 infiniti g35 sedans manufactured from march 29, 2004 through august 25, 2006 and infiniti g35 coupes manufactured from april 1, 2004 through may 30, 2007. The wire harness connecting the belt tension sensor (bts) and the occupant detection sensor (ods) control unit under the front passenger seat can experience relative movement which can cause wear and oxidization of the terminals and may cause interruption of the signal.

    Risk: In the event of a crash, the airbag may not deploy, increasing the risk of injury.

    Remedy: Nissan will notify owners and dealers will repair the vehicles free of charge. The safety recall began on july 12, 2010. Owners may contact nissan toll-free at 1-800-662-6200.

  2. NHTSA 06V394000Oct 13, 2006Electrical System23,934 vehicles

    Exterior lighting:headlights

    Certain vehicles fail to comply with the "vertical gradient" and "headlamp photometric values" requirements of federal motor vehicle safety standard no. 108, 'lamps, reflective devices, and associated equipment.'

    Risk: This standard is to reduce crashes, injuries and deaths by providing adequate illumination of the roadway, and by enhancing the conspicuity of motor vehicles on the public roads so that their presence is perceived and their signals understood, both in daylight and in darkness or other conditions of reduced visibility.

    Remedy: Dealers will replace the headlamp assemblies. The recall is expected to begin on or about april 16, 2007. Owners may contact infiniti at 1-800-662-6200.
