Electronic display in my 2020 Mitsubishi Pajero Sport has disappeared

The fact that all these features have gone AWOL all at once suggests the display unit itself might be the problem. That, or perhaps a fuse that controls the circuit the display draws its power from. If it was one function on its own, then you’d suspect a sensor for that system might be the problem, but when they all disappear at once, the digital readout unit would be the place to start checking.

However, don’t forget that your car has a five-year factory warranty, and this is most definitely a problem that – on the surface – appears as though it would be covered by the Mitsubishi warranty. Even if you bought the vehicle second-hand, provided the car has been serviced correctly, the warranty should still apply regardless of how many times the car changes hands.

You could try for a computer reset by disconnecting the battery overnight, but make this Mitsubishi’s problem, not yours.
