What causes the gear knob of the 2017 Mondeo to not rotate?

[Gene]

If the gear knob of the 2017 Mondeo cannot rotate, try pressing the brake pedal all the way down and then rotating it again. If it still doesn't rotate, it is likely due to an issue with the linkage or the gear knob itself. In this case, a diagnostic tool is needed to read the fault codes, and repairs should be carried out based on the fault code information. The Mondeo's gear knob has letters with lights underneath them; the illuminated light indicates the current gear in use. The 2017 Mondeo features a rotary gear knob: P stands for Park, used when parking by rotating the knob to P and engaging the electronic parking brake; N is Neutral; R is Reverse; D is Drive, used for driving by turning the knob from P to D and releasing the electronic parking brake; and S stands for Sport mode, which can be engaged by pressing the button when climbing or overtaking.
