2004 Porsche Cayenne

2 Defect Investigations from the NHTSA

NHTSA Defect Investigations for the 2004 Porsche Cayenne

The Office of Defects Investigations (ODI) is an office within the NHTSA which investigates serious safety problems in the design, construction or performance of vehicles. The NHTSA is authorized to order manufacturers to recall and repair vehicles, if the ODI finds a safety issue. NHTSA investigations for the 2004 Porsche Cayenne, both ongoing and closed, are listed below:

  1. SRS WARNING LIGHT ILLUMINATION NHTSA Preliminary Evaluation #PE05060

    • Status:
      CLOSED
    • Date Opened: November 10, 2005
    • Date Closed: March 15, 2006
    • Recall: no recall issued

    Component(s): Air Bags
    Air Bags:Frontal:Sensor/Control Module
    Air Bags:Side/Window

    Summary: During the preliminary evaluation phase, ODI identified 76 owner complaints and 6,582 warranty claims related to airbag warning light illumination from either a faulty side-impact airbag module or wiring harness.to date, there has been no allegation of crash, injury or death reported.Porsche reports that a bad batch of modules was produced during mid-November to mid-December, 2003.however, Porsche's warranty data indicates that most of the modules replaced under warranty were on vehicles built before and after this period indicating that the issue could be more widespread.Porsche reports that the wiring harness malfunction is due to a faulty connector leading to the airbag module as a result of environmental and mechanical stress.in June and November of 2004, Porsche added a protective coat of lubricant gel to the connector and rerouted the harness to fix the problem on all future production.Porsche has not issued a recall campaign, but it has circulated to its dealers two service bulletins, both in September 2004 to address the above issues.this investigation is being upgraded to an engineering analysis (EA06-005) and will include MY 2006 vehicles.

  2. SRS WARNING LIGHT ILLUMINATION NHTSA Engineering Analysis #EA06005

    • Status:
      CLOSED
    • Date Opened: March 15, 2006
    • Date Closed: March 12, 2007
    • Recall: no recall issued

    Component(s): Air Bags
    Air Bags:Frontal:Sensor/Control Module
    Air Bags:Side/Window

    Summary: Porsche is initiating a customer notification action to address a condition related to a faulty or loose connector in the side airbag system.Porsche's testing has shown that the faulty connector will not prevent side airbag deployment.the faulty connector will cause the circuit resistance to exceed the threshold for illumination of the air bag warning light.Porsche has reported a large number of warranty claims for illumination of the air bag warning light and many vehicles have been serviced to correct this condition as described in the Cayenne technical information bulletin: Group 6, #11/04 "airbag warning light activated."Porsche will perform this service to all remaining uncorrected vehicles under a new product improvement campaign starting at the end of April 2007.all owners of a subject vehicle built through November 2004 will be notified by Porsche to bring the vehicle to a dealer to receive the free modification.vehicles built after November 2004 do not contain the subject connector.in addition, Porsche reports that a small number of vehicles built in November and December 2003, may contain an incorrectly manufactured side airbag module.this may also produceillumination of the airbag warning light that would become evident soon after the vehicle is put into service.warranty data indicates that these modules have been corrected and no longer present a risk.Porsche has not received any report of non-deployment of the side airbag.the action taken by Porsche is sufficient to resolve the issue raised by this investigation.the closing of this investigation does not constitute a finding by NHTSA that no safety-related defect exists.the Agency reserves the right to take further action if warranted by the circumstances.
