Vehicle Rollaway

Basis – On December 16, 2016, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE16-014 to investigate 43 vehicle rollaway incidents with operators alleging they had shifted to Park and then exited the vehicle prior to the rollway incidents. These complaints involved multiple Fiat Chrysler Automobiles (FCA) model and model year vehicles that share a common electronic rotary shifter design. Of the 43 consumer complaints, 25 complaints alleged crashes, and eight complaints alleged at least one injury. Subject Vehicles – When NHTSA opened the investigation, the subject vehicles were model year (MY) 2013-2016 Ram 1500 vehicles and MY 2014-2016 Dodge Durango vehicles equipped with a rotary electronic shifter. However, NHTSA expanded the scope of the investigation to include subsequent model years of the same model vehicles when the Agency learned that those new model year vehicles use the same rotary shifter. Additionally, all subject vehicles manufactured by FCA are equipped with electronic rotary shifters supplied by Kostal Automotive. Reason for closing - During the course of this investigation, ODI did not find evidence that a vehicle-based design or manufacturing defect was the cause of vehicle rollaway incidents on the subject vehicles. Nevertheless, given the risk of a vehicle rollaway, FCA’s CSN actions provide automated vehicle securement when an operator attempts to exit the vehicle without successfully achieving a Park position with the rotary shifter mechanism. ODI closely monitored the subject vehicles on which the CSN actions implement a vehicle securement strategy and found that the CSN actions were effective in reducing the frequency of vehicle rollaway incidents in the subject vehicles. ODI analyzed the incidents when a CSN had been implemented and a rollaway still occurred, and ODI was unable to find an actionable defect that caused vehicle rollaway incidents. ODI found that the failure rates on subject vehicles that received a CS
