Power Steering failure - UCF20
My wife and I have had our LS400 for about a month now, and decided to take it to our first ever autocross event. Well, half way through the second lap, the powering steering went out and I limped back to the paddock. At idle and low speeds, the car groans when turning the wheel. Even turning the wheel, while stopped, just a couple degrees and holding it causes a groan, as if the PS is trying to help.
This marks the third time the PS has gone out, the first two were when I drove it 8 hours home from picking it up. I let it sit for awhile the first two times (over night, and around 2 hours) and it started working again. This time, not so much luck.
Any thoughts on what happened and if the autocross could've caused it? Maybe some air in the system? I checked the fluid level and it looked ok. I plan on doing a flush ASAP, and hopefully that will fix it, but do you guys have any other experience or ideas?

"The power steering went out" Isn't that like saying my car don't want to work no moe, can anyone tell me whats wrong with it?
So what part of the power steering went out? The rack? The pump? The hose over there or the one up there? You where just driving a poof it stopped working?
Maybe the pressure relief spring broke?

I would suspect Power steering fluid is being used instead of trans fluid. Had this happen in a 2000 tundra, when the power steering presumably went out... even thought the reservoir was full. Found a container of standard power steering fluid in the cab. Flushed out the fluid and replaced with trans fluid (dexron) and been working fine every since.

Manual and cap for power steering fluid reservoir both state ATF... I don't think there is any question there.
My experience with the Tundra shows it does indeed make a difference. YMMV... as always.
