NHTSA Preliminary Evaluation PE11025

In response to the Office of Defects Investigation's (ODI) Information Request (IR) for PE11-025, BMW provided ODI with 1 complaint and 46 field reports relating to either incidents of unattended vehicle rollaway or vehicle movement after the driver expected the vehicle gearshift to automatically shift to park. ODI's analysis of the data provided by BMW identified 14 crashes and 5 alleged injuries. ODI has also identified 3 additional reports in its database alleging vehicle rollaway incidents of which 2 resulted in crashes.The subject vehicles are all equipped with push-buttons (Start/Stop button) to control starting/stopping the engine and Shift-by-Wire gearshift systems controlled by a column mounted selector lever behind the steering wheel. The Start/Stop button also controls switching the ignition and the radio ready state On and Off. Shift-by-wire systems replace the traditional mechanical connection (e.g., cable or linkage) between the gearshift and automatic transmission with an electronic connection controlled by a computer module. When parking the vehicle, the driver has the capability to manually shift the vehicle to park by pressing the Park button on the end of the electronic gearshift lever. However, the instructions for engine shutoff provided in the owner's manual state that pressing the Start/Stop button serves the dual function of switching off the engine and automatically shifting the transmission to Park.In response to ODI's information request for PE11-025, BMW described several circumstances where the subject vehicles may shift to neutral when the driver may expect it to automatically shift to park. First, for Comfort Access System (CAS) vehicles, if the transmission is in neutral when the key fob is in the ignition slot and the Start/Stop button is pressed to shut-off the engine, the transmission will remain in neutral. This is referred to as the Carwash mode and is a normal operating feature of the vehicles that is described in the owner's ma
