So here's an interesting one... I've started driving a new route to take the kid to daycare. This is a twisty road, with lots of 90 degree corners which I take at speeds anywhere from 30-50kph. In one single corner (a 30kph one), I've gotten the "Check 4 wheel AHC system" message 3 separate times. The message appears for a blink of an eye, no more than a few seconds, and vanishes.

I'm guessing there's some funky geometry to this corner and/or how I take it, resulting in AHC fluid swinging around in the reservoir, and setting off some kind of low fluid level alert? Any other ideas?

I've driven this road many times in the past (although without any regularity) and have never had this message come up. Perhaps there's a slow fluid leak and the level has gotten low enough to result in throwing this message/error? I haven't yet had a chance to check the fluid level.
 
I had a hill on a trail I frequented and would always get that message at the top at it's most steepest—turns out my fluid was low
Did you ever track down a leak? Or was it low enough to be inconsequential?

No, in coincided after I changed my accumulators so chalked it up to just being short on fluid after I bled everything.
 
This is the fluid level. Sitting in my level driveway, at normal height.

Seems fine to me, no?

If anything, might be a bit high?
