NHTSA Defect Investigations for the 2002 Land Rover Range Rover

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 2002 Land Rover Range Rover, both ongoing and closed, are listed below:

  1. INVESTIGATION: FRONT DIFFERENTIAL/DRIVESHAFT FAILURE

    NHTSA Preliminary Evaluation #PE07019

      CLOSED
    • Date Opened: April 04, 2007
    • Date Closed: August 15, 2007
    • Recall: No recall issued

    Component(s): Power Train:Axle Assembly:Axle Shaft
    Power Train:Driveline:Differential Unit
    Power Train:Driveline:Driveshaft

    Summary: In response to an information request (ir) letter sent by the Office Of Defects Investigation (ODI), Ford stated that the primary cause for the majority of the reported front differential/drive shaft failures is a misalignment of the joint between the two components.certain levels of misalignment may over time cause an uneven wear of the splines.continued wear of the splines may result in a shearing of the splines and the inability of the driveshaft to transfer torque to the front differential. To address the issue in the field, Ford initiated a service campaign in June 2003 to correct the misalignment issue and, if necessary, replace the front drive shaft and/or differential.the service campaign covered model year (MY) 2003 and MY 2004 vehicles built from April 18, 2002 through July 3, 2003.in production, Ford introduced a change to the lubricating grease of the joint in February 2003 and a change to the assembly plant alignment process in July 2003 to address the misalignment and wear issue. ODI identified one crash related to the alleged defect.the crash involved a subject vehicle being struck in the rear after becoming disabled by a front differential/driveshaft failure and pulling to the side of the road. This preliminary evaluation has been upgraded to an engineering analysis (EA07-012) to further assess the scope, frequency and safety consequences of front differential/driveshaft failures in the subject vehicle population.
