NHTSA Investigation EA01017

ROLL-AWAY IN REVERSE WHEN PARKED

DAIMLERCHRYSLER HAS RECALLED THE ZJ MODELS TO INCORPORATE A SECONDARY DETENT SPRING INTO THE SHIFTER.EVEN THOUGH THE WJ 6 CYL. VEHICLES USE THE SAME MANUAL DETENT LEVER THAT AS THE VEHICLES IN THE RECALL POPULATION, ODI BELIEVES THAT THE WJ REDESIGNED SHIFTER, WHICH IMPROVES FLOOR SHIFTER FUNCTIONALITY AND ERGONOMICS, HELPS TO PROVIDE FEEDBACK TO THE DRIVER TO INDICATE WHETHER ?PARK? HAS OR HAS NOT BEEN ACHIEVED.ALTHOUGH THE INVESTIGATOR WAS ABLE TO INDUCE A ?FALSE PARK? IN THE WJ PLATFORM FOR 6 CYL. VEHICLES, THE LEVEL OF DIFFICULTY WAS GREATER THAN THAT REQUIRED FOR ALL ZJ MODELS, AND THE COMPLAINT RATE WAS SIGNIFICANTLY LOWER THAN THE RECALLED ZJ POPULATION.FURTHER, THE ODI INVESTIGATOR WAS ALSO ABLE TO CREATE A ?FALSE PARK? IN PEER VEHICLES WITH THE SAME LEVEL OF DIFFICULTY AND FREQUENCY AS THE SUBJECT VEHICLE WJ PLATFORM.THE WJ COMPLAINT RATE WAS INFLATED DUE TO NATIONAL EXPOSURE THROUGH THE PRESS. THE COMPLAINT RATE PRIER TO THE JULY 5, 2001 MEDIA COVERAGE FOR THE WJ VEHICLES IS SIMILAR TO THE PEER VEHICLE INCIDENT RATE.BASED ON THE ABOVE, A SAFETY-RELATED DEFECT TREND HAS NOT BEEN IDENTIFIED AT THIS TIME IN THE WJ POPULATION.ACCORDINGLY, THIS INVESTIGATION IS CLOSED WITH A SAFETY RECAL FOR THE ZJ PLATFORM ONLY.

An investigation is a separate record from a recall and from a manufacturer communication. A manufacturer campaign to repair a safety defect or a failure to meet a federal safety standard.
