Transmission Not Engage problems of the 2013 Lincoln MKX

In regards to my 2013 Lincoln Mkx, the automatic transmission frequently does not engage in park --- about half the time. When stationary, the automatic transmission gear shift lever is pushed into the "p" position, but the vehicle warns via a dinging and dash warning that it is not in park. Stationary locations include my garage, which is level, and public parking lots, which are typically level in my area. There is an existing recall for the 2013 Lincoln Mkx (ntsa campaign number: 14n393000), which regards a defective "half-shaft disengagement". It includes comment that until repaired, when stopped to engage the parking brake or the vehicle could roll away. I do not know whether that recall involves the problem with my Lincoln. A search was performed on your website for a recall on my vehicle using its VIN, but no recall was found.
