Howling Electric Steering-wheel Adjustment

[Theorist]

Can any one help? I have a MKI GS300. When the sun has been on the car and the interior temperature has risen, the memory sterring wheel gizmo makes the most awful howling noise. It is a friction noise, I guess that differential expansion on some part of it or other causes it to tighten up. On extreme occasions it grinds to a halt. Is there any remedy that anyone can think of that can be carried out by a non-mechanic - lubrication for example - and how would one go about it?

Hi,

Ive read about this in a post some time back,not sure weather it was here or on the US site.

I think Toyota/Lexus replaced parts under warranty for this problem.

There might be a old post with a fix for this problem

Sorry i cant be of more help.

there is a TSB for this on early series II models which is to replace the assembly with a modified unit. Never heard about it on the series I.

I would recommend you post on the US forums, many more GS owners there and they would tend to run into this problem more frequently as the issue only occurs in hot weather.
