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 2006 Chevrolet Uplander, both ongoing and closed, are listed below:

  1. INVESTIGATION: POWER SLIDING DOOR

    NHTSA Engineering Analysis #EA07019

    • Status:
      CLOSED
    • Date Opened: December 11, 2007
    • Date Closed: February 23, 2009
    • Recall: No recall issued

    Component(s): Latches/Locks/Linkages:Doors:Latch
    Structure:Body:Door
    Structure:Body:Door:Hinge And Attachments

    Summary: ODI evaluated General Motors' (GM) data, conducted consumer interviews, inspected and tested MY 2005-2007 GM minivans with regard to the alleged defect of a power sliding door (PSD) opening while the vehicle is out of park.ODI identified a high warranty claim rate.however, these claims are related to various problems associated with doors not properly opening or closing and not specifically to doors opening while driving.the condition of the PSD reversing direction during the closing sequence is consistent with an obstruction of the door, or with improper alignment of the door, and this is addressed in GM technical service bulletin # 07-08-64-007 and bulletins # 07-08-64-007A through D.ODI's evaluation of the PSD system notes numerous safeguards to preclude both unintentional and intentional power opening of the PSD while the vehicle is in motion.a safety-defect trend has not been identified at this time.accordingly, this investigation is closed.[see document file for additional information regarding this resume.]

  2. INVESTIGATION: POWER SLIDING DOOR OPENING

    NHTSA Preliminary Evaluation #PE07044

    • Status:
      CLOSED
    • Date Opened: August 16, 2007
    • Date Closed: December 11, 2007
    • Recall: No recall issued

    Component(s): Latches/Locks/Linkages:Doors:Latch
    Structure:Body:Door
    Structure:Body:Door:Hinge And Attachments

    Summary: ODI has received reports that the power sliding doors opened without command while the vehicle was in motion on model year 2005 and 2006 General Motors minivans (Chevrolet Uplander/Venture, Pontiac Montana SV6/Montana, Buick terraza, and Saturn relay).some reports indicate that the door may not have been closed and latched before driving away causing the door to reverse (open) at low vehicle speeds.however, other reports indicate that the door was initially shut then opened after driving for several minutes and/or miles at vehicle speeds between 20 and 70 mph.ODI has upgraded this preliminary evaluation to an engineering analysis (EA07-019) to further assess this issue.
