When car comes to a stop, and the driver pushes the button to put the car in "park", the car does not go into park, but stays in "drive" or "reverse". driver leaves car, and because driver is unaware that the vehicle remains in "drive", and did not switch to "park", the car can begin to idle forward while driver leaves or has left the vehicle, or idles in reverse, as driver leaves or has left the vehicle, as the "park" position is not activated. This can be quite dangerous to the driver, or to passengers or pedestrians. At times, the car does go into "park", but at other times, it does not, it stays in "drive" or "reverse", misinforming the driver. This is an unsafe situation.

With the gear selector in park and the passenger side front seat occupied, the vehicle rolled backwards from a 4.4 percent grade and overturned as it proceeded downhill. Inspection of the transmission parking gear revealed that the parking pawl had been activated but did not engage a parking gear slot. This incident was attributed to excessive angle on the parking gear slot sides, an underpowered pressure spring in the park interlock mechanism, or a combination of both of these conditions. These conditions permitted the parking pawl to be rejected from the parking gear slots at speeds well below the park pawl engagement (target) speed of 6 kph (3.7 mph), as defined by sae specification J2208. A series of such rejections while the drivers seat is unoccupied poses a safety hazard by allowing the vehicle to continue to roll in an uncontrolled manner on certain slopes while the gear selector is in park. A more detailed analysis of this issue has been prepared and shared with Mercedes-Benz. Please contact me to obtain this analysis and the related response from Mercedes-Benz representatives.

The car was on an incline in my driveway. It has the transmission shift lever on the column, and I had been backing down the driveway. I stopped placed the car in park and got out with the engine running to move something. The car sat in place for approximately 10 seconds and then spontaneously took off at approximately 5miles/hour. Fortunately my daughter was standing on the driver side of the car in front and saw the car rolling forward, jumped in and hit the brakes just as the car struck one of other cars on the driveway. The shift lever was reading the drive position, even had I not placed the car in park, it would not have been in drive but reverse as I had been proceeding down the driveway.
