Warning lights on start and Adaptive Cruise Control

[FNQ California]

Hi everyone.
Yesterday on start all the warning alerts came on: abs, side assist, on/off, downhill descent etc.
I drove a few kms and stopped, on restart they all went out except Adaptive Cruise Control wouldn't start. Stopped for fuel an hour later and on start, ACC worked.
This morning the same sequence.
We did 1,000 km drive before this and there were some very rough bits of road towards the end.
Seems a sensor fault, but which one?
Any suggestions, or is a trip to the dealer required?
Many thanks.

One of the Wheel speed sensors is failing.

So is this more than just an...
