NHTSA's summary
As NHTSA's Office of Defects Investigation wrote it for Engineering Analysis EA04-025.
THE SUBJECT VEHICLES ARE HEAVY DUTY PICKUP TRUCKS WITH DIESEL ENGINES AND AUTOMATIC TRANSMISSIONS COMMONLY USED FOR COMMERCIAL AND WORK PURPOSES.A COLUMN MOUNTED SHIFT LEVER IS USED FOR GEAR SELECTION AND AN ELECTRONIC PRNDL ON THE INSTRUMENT PANEL PROVIDES GEAR POSITION INFORMATION TO THE DRIVER.THE SUBJECT VEHICLES ARE ALSO EQUIPPED WITH A BRAKE-TRANSMISSION SHIFT INTERLOCK THAT PREVENTS THE SHIFT LEVER FROM BEING MOVED FROM THE PARK POSITION (WHEN THE ENGINE IS ON) UNLESS THE BRAKE PEDAL IS DEPRESSED AND AN IGNITION-SHIFT INTERLOCK THAT PREVENTS KEY REMOVAL UNLESS THE TRANSMISSION IS IN THE PARK POSITION.COMPLAINANTS GENERALLY REPORT THAT THE VEHICLE WAS BEING OPERATED IN A FORWARD GEAR AND BROUGHT TO A STOP THROUGH BRAKE APPLICATION ON ALEVEL SURFACE, AT WHICH TIME THE OPERATOR MOVED THE SHIFT LEVER TO ENGAGE THE PARK POSITION.THE OPERATOR THEN OPENED THE DRIVER SIDE DOOR AND, WITHOUT VERIFYING PARK ENGAGEMENT (E.G., PRNDL GEAR INDICATION), SECURING THE PARK BRAKE, OR TURNING THE ENGINE OFF, EXITED THE VEHICLE.INITIALLY, NO VEHICLE MOVEMENT WAS APPARENT, HOWEVER, A SHORT TIME LATER, TYPICALLY REPORTED AS 10 TO 30 SECONDS, THE VEHICLE MOVED REARWARD UNDER ENGINE POWER.THE INCIDENT OFTEN ENDED IN A VEHICLE CRASH, AND SOMETIMES INVOLVED SERIOUS INJURY.TWO FATALITIES ARE ALLEGED.ODI?S ANALYSIS OF TEST VEHICLES AND SOME INCIDENT VEHICLES FOUND NO EVIDENCE TO INDICATE THAT A SHIFT LEVER PROPERLY PLACED IN PARK COULD UNINTENTIONALLY (I.E., WITHOUT DRIVER INPUT) DISENGAGE FROM THAT POSITION.HOWEVER, ODI DID FIND THAT THE SHIFT LEVER COULD BE INADVERTENTLY PLACED, AND REMAIN AT REST, WITHIN AN INTERMEDIATE POSITION BETWEEN THE PARK AND REVERSE GEAR POSITIONS.WHEN PLACED IN SUCH AN INTERMEDIATE POSITION, THE VEHICLE CAN EXPERIENCE A DELAYED PRESSURIZATION OF THE REVERSE HYDRAULIC CIRCUIT THAT IS SUFFICIENT TO CAUSE THE VEHICLE TO ROLL REARWARD UNDER POWER.THE DELAY PERIOD ALLOWS SUFFICIENT TIME FOR OPERATORS TO EXIT THE STATIONARY VEHICLE WITHOUT PERCEIVING THAT THE SHIFTER IS NOT IN PARK.THE SUMMARY REPORT DISCUSSES THE TECHNICAL ANALYSIS OF THIS ISSUE IN GREATER DETAIL AND COMPARES THE FREQUENCY OF THESE INCIDENTS IN THE SUBJECT VEHICLES TO OTHER PEER VEHICLES THAT ODI EXAMINED.AS DESCRIBED IN THEIR OCTOBER 4, 2005 LETTER TO NHTSA, DAIMLERCHRYSLER CORPORATION (DCC) WILL CONDUCT A SAFETY RECALL (NHTSA RECALL NO. 05V-462, DCC NO. E17) TO INSTALL AN OUT-OF-PARK ALARM SYSTEM IN THE SUBJECT VEHICLES.THE ALARM WILL PROVIDE AUDIBLE AND VISUAL FEEDBACK TO ALERT THE DRIVER, AND OTHERS, IF THE DRIVER ATTEMPTS TO EXIT THE VEHICLE WHILE THE ENGINE IS RUNNING AND THE SHIFT LEVER IS NOT IN THE PARK POSITION.THE TIMING OF DCC?S ACTION HAS YET TO BE DETERMINED.
Vehicles and equipment listed for this investigation
NHTSA's investigations file lists these vehicles and equipment for Engineering Analysis EA04-025. A listed model year means only that an investigation names it; it says nothing about any particular vehicle. Model years with a try.vin recall page link to that page's NHTSA investigations section.
What an NHTSA investigation is
NHTSA's Office of Defects Investigation (ODI) looks into possible safety defects in vehicles and equipment, often after owner complaints. An investigation usually starts as a Preliminary Evaluation, or as a Recall Query when it concerns whether an existing recall covers the right vehicles or fixes the problem, and ODI can upgrade it to a more detailed Engineering Analysis. A Defect Petition asks NHTSA to open an investigation, and Audit and Equipment Queries are administrative investigations into whether companies complied with federal vehicle safety requirements, such as reporting, recall and certification rules.
An open investigation is not a finding that a safety defect exists, and NHTSA can close one without a recall.
