Vehicle: LAND ROVER RANGE ROVER View model page

NHTSA investigation EA07012 is a Engineering Analysis opened on 2007-08-14 and currently closed. The subject of record is LAND ROVER RANGE ROVER, which places this file inside the Office of Defects Investigation queue for LAND ROVER. Latest activity on this investigation was logged on 2008-12-10 — NHTSA updates that field whenever an Information Request goes out, a supplement is filed, or a status change is recorded in the public docket.

An Engineering Analysis like EA07012 is the deeper technical phase that follows a PE. NHTSA requests design, warranty, and field-failure data from the manufacturer, conducts its own testing when needed, and determines whether the evidence supports a safety defect finding that would compel a recall.

Investigators summarized the matter as follows: "SUMMARY: IN A LETTER DATED DECEMBER 2, 2008, FORD MOTOR COMPANY (FORD) NOTIFIED NHTSA THAT LAND ROVER IS CONDUCTING A SAFETY RECALL OF MODEL YEAR (MY) 2003 THROUGH 2005 RANGE ROVER VEHICLES BUILT AT THE SOLIHULL (UK) ASS..." Investigations are the early-warning layer of the federal auto-safety system, sitting upstream of formal recalls and defect orders. Whether this one closes without action or escalates into an Engineering Analysis, the full history stays in the ODI archive so researchers, litigators, and buyers can pull the paper trail at any time. Related LAND ROVER files, listed below, give context on whether this is an isolated concern or part of a broader pattern across the brand.

Investigation Summary

SUMMARY: IN A LETTER DATED DECEMBER 2, 2008, FORD MOTOR COMPANY (FORD) NOTIFIED NHTSA THAT LAND ROVER IS CONDUCTING A SAFETY RECALL OF MODEL YEAR (MY) 2003 THROUGH 2005 RANGE ROVER VEHICLES BUILT AT THE SOLIHULL (UK) ASSEMBLY PLANT FROM JANUARY 3, 2002 THROUGH FEBRUARY 22, 2005, TO REPLACE THE FRONT DRIVESHAFT JOINT (NHTSA RECALL NO. 08V-635, LAND ROVER RECALL NO. P041). THE FRONT DIFFERENTIAL COUPLING SLEEVE AND THE PROPELLER SHAFT MAY BE MISALIGNED RESULTING IN SPLINE WEAR OVER TIME, WHICH MAY EVENTUALLY RESULT IN THE SPLINES SHEARING. THE DEFECT CONDITION CAN RESULT IN A LOSS OF PROPULSION AND SUBSEQUENT VEHICLE DISABLEMENT IN THE ROADWAY OR ON THE SHOULDER OF THE ROADWAY. FURTHERMORE, THE DEFECT CONDITION CAN ALSO CAUSE LOSS OF THE TRANSMISSION LOCK FUNCTION WHEN THE VEHICLE IS SHIFTED INTO THE PARK POSITION. THE LOSS OF THE TRANSMISSION LOCK FUNCTION CAN CAUSE A VEHICLE ROLLAWAY CONDITION IF THE EMERGENCY BRAKE IS NOT APPLIED AND THE VEHICLE IS UNATTENDED BY THE DRIVER. IN JULY 2008, LAND ROVER INITIATED A SERVICE ACTION (Q041) INSTRUCTING DEALERS TO INSTALL A REDESIGNED FRONT PROPELLER SHAFT, FRONT DIFFERENTIAL COUPLING AND HEAT SHIELD KIT TO ADDRESS THE MISALIGNMENT AND SUBSEQUENT SPLINE WEAR. THIS IS THE SAME REPAIR PROCEDURE THAT WILL BE USED IN SAFETY RECALL 08V-635. APPROXIMATELY 48 PERCENT OF THE SUBJECT VEHICLES (18,000) HAVE HAD THE REMEDY PERFORMED UNDER SERVICE ACTION Q041 AS OF DECEMBER 2, 2008. ODI BELIEVES THAT SUDDEN LOSS OF MOTIVE POWER WITHOUT WARNING AND FAILURE OF THE TRANSMISSION LOCK FUNCTION ARE SAFETY CONSEQUENCES THAT, PARTICULARLY IN THE CONTEXT OF THE HIGH FAILURE RATE OF THE SUBJECT COMPONENTS, REPRESENT AN UNREASONABLE RISK TO MOTOR VEHICLE SAFETY AS STATED IN A RECALL REQUEST LETTER SENT TO FORD AND LAND ROVER ON NOVEMBER 6, 2008. LAND ROVER DOES NOT AGREE, BUT IS CHANGING ITS CUSTOMER SATISFACTION PROGRAM TO A SAFETY RECALL AS ODI REQUESTED. LAND ROVER NOTED THAT IT WAS AWARE OF ONE ALLEGED ACCIDENT; HOWEVER, IT WAS UNAWARE OF ANY

About This Investigation Type

An Engineering Analysis (EA) is the in-depth phase following a Preliminary Evaluation. NHTSA engineers conduct testing, collect data from manufacturers, and perform detailed technical analysis to determine whether a safety defect exists. An EA may lead to a voluntary recall by the manufacturer or, in rare cases, a mandatory recall order.
