RX 400h steering is dangerous on accelerating

[mudplug]

Hi guys, does anybody know if there is a mod/update to stabilize the steering if accelerating hard on on an overtake or something? At the moment I find if I put my foot down to overtake then the steering is all over the place as the front wheels fight to get a grip to the extent I would say it is dangerous!

What state are your front tyres in and what pressures are you running? I've never experienced this.

I'd get the suspension bushes checked out. Worn bushes will make the car track badly and it'll be all over the place.

All tires are good with plenty of tread on them and I normally run on about 35 psi, but looking on UTube there seems to be a lot of comments on this problem so I am at a loss, I am in two minds if to see if a steering damper could be fitted?

The torque steer is a well known effect, you just have to learn to handle it. Don't just jab your foot down (or if you do, just be ready for it happening) but use a lighter right foot instead.

How long have you had the car?  If it's a change that you've noticed then it needs further investigation.

What's the tyre pressure recommendation on your car?  Mine is 32psi and the front tyres look virtually flat at that, but that's what it should be.  So do double check on that, might make enough of a difference.  Some torque steer will always be there - everyone expects that and, occasionally, it will still surprise everyone.

Is it a traction problem (loss of grip),  or torque steer?

Mine exhibits this too if accelerating wildly, and it can turn into a tank slapper if not careful.  It's not a grip issue - but torque steer.  I just learnt to use my right foot carefully.

Yes - I too think it's torque steer, and when you first experience it, it's VERY disconcerting bordering on dangerous.  When it happens during a critical overtake your first reaction is to back off - not only is this at exactly the wrong point in the overtake, but the reduction of power/torque to the front end makes it sway alarmingly in the opposite direction.  I am surprised no-one has rolled their cars doing this.
