I have a 2021 f150 and when the car is off, it makes this clicking noise and the gauge cluster lights up, I don’t have the keyless entry so it’s not locking or unlocking itself so I don’t know what’s going on
It has approach detection stuff, my truck as well as my wife's Explorer both do it. Sounds like gremlins in there start doing things as soon as you walk near it, not sure the full list of things it starts doing, but a bunch of systems definitely seem to "wake up".
I have a lot of things disabled on my truck, such as the welcome thingy, that turns lights on and flips out the running boards. There's always noises after parking it, like 20-30 min later and once again about an hour later. Things going to sleep i guess...
