check the battery
A good working batterie is the first and easiest to check.
In my case it happens when the batterie is new or comming of the charger,
or when the batterie is not good anymore. You can notice this when the windows programming need to be redone every time you use the car.
After a month or so normal car use the message disappears.

I have the same problem as you, although mine seems to be caused by water ingress* so if the intermittent problem only happens when it's raining then that could be something to look at.

Mine sits more than I drive it, and routinely shows those warnings upon start if/when the battery gets pretty low. Apparently this booger sips a fair amount of juice when it's parked (as I'm guessing most cars these days do because of all the electronics). Recharge your battery or replace it, and see if that changes the behavior (at least for a while).

- Remove each wheel in turn, check and clean the ABS sensor (just a bolt) AND the connector/boot.
- Check the ABS ring, make sure it is solid with the hub.
- While there, bleed the hydraulic fluid on each caliper. Gently tap the caliper with a hammer to dislodge air bubbles (a clear tube helps to see this).
- Check other basics, like tire air pressure. A severely deflated tire could give you codes, I suppose. Tire are the same size left-to-right, right?
- Once this is done, put it all back together and do a test drive. If fixed, the system needs a short drive to reset.
- If none of this works, then it might be time to check the ABS module internals. My understanding is that the solder comes loose at the power posts, and that can "easily" be fixed (never done this myself), or sent out for repair.
Best of luck, keep us posted.
