I bought an MKX recently to tow after doing much research and speaking online to lincoln reps numerous times. Here is a new message I got TODAY using my specific VIN # that was built in July. THEY CAN BE TOWED 4 DOWN!!! I've personally put mine in the "stay neutral" mode and it works...apparently my dealer updated the software as I can do exactly what she says I should do on my touch screen. Now to order the base plate and have it welded is next...
Here's lincoln's response today:
It seems your vehicle was built 07/17/2015 prior to the changes to allow the tow. You can still be flat towed, but require a software update to perform the selections as described in the owner manual (preferred method). Because your vehicle was build prior to 09/17/15 it may not have the ability to enable/disable the neutral tow function in the vehicle settings menu of the instrument cluster message center. The vehicle can be flat towed by following these steps: 1. Key the car on, 2. Shift to neutral, 3. Cluster will display a popup stating “Press N again to lock in neutral mode”, 4. Press N again, 5. Shut vehicle off, This will lock the car into neutral with the vehicle turned off, for towing purposes. Please see the dealership for the necessary updates needed.
