My steering rack was replaced by the garage from another IS. Now the steering is fine. Finally. I drove another IS that had the same notchy steering. Calibration doesn’t work. Lexus knows the issue but doesn’t really acknowledge it, which is a shame. My Lexus is from 2015.

Hi Job

I just clicked on the link in my post and the PDF downloaded fine. Here is the link again:

Unfortunately I doubt this is the same issue you are experiencing as the TSB was for the first batch of vehicles produced and was fixed for all vehicles produced after August 2013.

 

 

I notice in the TSB that the replacement part has the same part number as the original part. So no new technical requirements I guess of that part. Just some faulty parts.

Hi Colin, thank you for that. I hope it's not the same issue since I'm out of warranty but it is exactly like you describe. It happens after a while at high speed and just every now and then. I have to overcome a force to move the steering wheel. As if there are magnets in the steering column. Only on high speed left handers on the motorway. It occurs at the end of a bend when I try to turn the wheel straight again.

With the purchase of my IS, I have had the garage fit winter tyres. Vredestein wintrac extreme S.

I must say, the car also pulls slightly to the right.

My hopes are that a re-alignment of the wheels and maybe a software update of the steering rack can fix my issue. It's actually a quite dangerously issue.

My issue isn't anything to do with variable resistance steering. Many of my previous vehicles have had that, I know how such a system should feel. My issue is an intermittent issue, that only seems to occur once I've driven for quite a distance at high speed.

There is a TSB - I have a copy, I've attached it, and it is for both the IS250 and IS300h. I swear some dealers don't do any work and just fob off their customers.

My steering assembly has just been replaced, under warranty and obviously approved by Toyota GB so the TSB is valid.

It will probably be a week or two before I make a journey that would normally cause an issue so don't know for sure if the issue has been resolved.

Hi Colin, I'm from Holland and I've just bought a 2015 IS 300h. I did a first big trip to Austria and after a few hours driving I noticed the sticky steering. I googled for it and found your note on this. Unfortunately the link to the TSB is not working anymore. Could you please post that TSB again so I can download it?

Cheers, Job
