I have previously reported on various missing functions on my 2016 Lincoln KMX. Those included the ability to disengage the auto fold mirror function the neutral tow function the ability to change speedo to digital but now I have recently discovered that the ability to have horn chirp when locking the car after 2 presses of the key fob is not there. These items are all referred to in the owners manual. What happened to quality control when these vehicles were being manufactured?? Lincoln is supposed to be a premium vehicle or so I thought.
