Hello, My dad has a 2007 fully stock is250. Today he try to move his car to another space on the street. suddenly, his steering is locked and unable to turn.
This first time we encounter this problem. I tried to turn the wheel while on IG-on.( I think this can override the pwr steering wheel to manually move steering of the car) The steering wheel doesn't loosen, but the tire could move. WE also tried disconnect the battery still no good.
Anyone have any suggestion or solution?

 

So are you getting power to everything else in the car? Like it will turn on and the engine will start, it's just the steering wheel won't turn?

The only time I ever experienced something like that was when I was driving my LS400 and the power cut out, including the power steering, so the steering locked up. The reason was that the alternator failed - the battery was fine, but the alternator wasn't charging it.

 

ya eveything is find. car will turn on, just can't turn the wheel at all. There is no error msg show up on dashboard. My uncle just checked, and he think it might be the p/s motor is dead. We will see.. $.$

 

put some elbow grease in it.

the gs sometimes get stuck too, it usually happens when you dont park with the steering wheel straight.

try sticking the key in and not starting the car turn the steering wheel (without breaks).

 

^^^Sticking what key in?

That happened on my cousin's 08 250... I just shut the car off and re-started it... Wish I could tell you more...

 

Lol this just happened to me last week. Since the IS has a push button start, I have no idea what to tell you. Try muscling the steering wheel.

 

Try "Jiggling" the wheel when you start the car ... My moms RX had her steering wheel lock and the car wouldn't start... called up lexus and they said to jiggle it when we started the car and it worked!

 

+1 had this issue a couple days ago and I did this to get it to release

I know this is an old post. but having this same problem, what was the fix?

 

I've got the same issue right now and like another comment said the only way of "fixing" it is jiggling the wheel as you start it. it could be alternator because I've changed my battery and it was all good for about a month before starting to lock up again. my p/s steering module also doesn't look terrible.

 

I got this issue and it said bad steering gear motor relay or something like that. Every time I turn on the car, right at start up I must jiggle my steering wheel left n right or else I won’t have power steering and I have to restart the car to redo the process.


it also makes a weird sound like as if it’s going through some torsion or something, it’s hard to explain. But technically the power steering still works, it’s just louder when turning the wheel wheel more than like 90 degrees.
