I have recently noticed that if I quickly turn the steering on my Prius from lock to lock (such as a quick and tight 3 point turn in the road) the steering feels like it's running out of power on and off. It's difficult to describe but it feels like the power isn't enough to quickly turn the wheel from lock to lock. Say you reverse the car slightly whilst turning from lock to lock and then select drive and then turn lock to lock again, the steering goes light, heavy, light, heavy etc. Is this normal under these circumstances or is it a problem developing? Once you get going it's all normal again. I had the car in some months ago for a steering column issue where something was replaced and the steering tightened up nicely. It is now starting to have a teeny bit of play in it again and then the issue quoted above. Just thought I'd run it by you guys before I contact the dealers. I'm not working for a few days so no worries there. Advice appreciated.
