NHTSA's summary
As NHTSA's Office of Defects Investigation wrote it for Preliminary Evaluation PE11-025.
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 manual. BMW also described two circumstances that are not normal operating features and are not described in the owners' manual: (1) with the transmission in drive or reverse and the engine running, if the Start/Stop button is pushed 2 or 3 times within a 0.3 second to 0.5 second interval, the engine will stop and the transmission will shift to Neutral; and 2) if the Park button on the gearshift lever is pressed at the same time that the gearshift lever is actuated (i.e., toggled up or down) to select drive, reverse or neutral; the transmission will shift to neutral or remain in neutral.
Beginning in model year (MY) 2005, BMW introduced CAS as an optional feature package for the subject vehicles.
The key for CAS equipped vehicles is an electronic code that is sent to the engine control module by a remote transmitter (key fob). An optional docking port (key slot) is provided for driver convenience or to put the vehicle into Car Wash mode, which allows for engine shutoff in neutral. BMW sold approximately 45,000 subject vehicles with CAS and approximately 94 percent of the CAS equipped vehicles were produced from MY 2006 through 2008. Non-CAS subject vehicles were produced from MY 2002 through 2008 and require the remote control to be in the ignition slot located next to the Start/Stop button to start the engine.
The 50 incidents identified by ODI's analysis of complaints and field reports include 18 involving CAS vehicles (39.6 incidents per 100,000 vehicles) and 32 involving non-CAS vehicles (42.0 incidents per 100,000 vehicles). Because the incidents are considered random events, the failure rates were also adjusted for vehicle exposure, resulting in rat
Vehicles and equipment listed for this investigation
NHTSA's investigations file lists these vehicles and equipment for Preliminary Evaluation PE11-025. 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.
