When I would cut the wheel all the way to one side when exiting my driveway the dash and entertainment components would lose power. I racked my brain trying to figure out why. The problem was intermittent so it was hard to nail down until I noticed something. The colder the weather the worse and more persistent the problem. In fact on one of the coldest days as I executed a turn with the steering wheel fully turned not only did the various dash things shut off the wheel forced itself to straight up slightly from its fully turned state. That's when I figured out it was the power steering fluid. There was a small amount of air in the line and the level was just barely too low. Once the fluid would heat up and could move with less resistance it stopped doing it. So I bled the line and added a tiny amount of e-psf, problem solved. To test it I took it to a parking lot, cut my wheel all the way to one side and let it idle in a circle for 30 seconds or so.

The problem is that the power steering draws more electrical power the more stress the power steering is under. When the PSF is cold it is more viscous and puts more stress on the power steering. When I exit my driveway I turn the wheel all the way to one side and the further you turn the wheel under any circumstance the more stress the power steering is under. Combine the viscosity of the cold PSF, with an underfilled reservoir that has air trapped in the line and turning the wheel all the way you get a momentary loss of power. Also because I was exiting my driveway I would let the car's idle speed make the turn for me so the alternator wasn't producing as much power as it would if executing a more routine sort of turn where I had engaged the throttle.
