Lexus RX450h - rattle noise from the steering wheel

[Geoff88]

My Lexus RX450h F-Sport (7500milage) recently developed rattle noises when driving over roads with uneven or rough surface, and it feels coming from the steering wheel. I also feel a tiny vibration of the steering wheel when the rattle noise occurs. I checked tyre pressures and they are all at 2.3 Bar. The noise has become more frequent and noticeable in the last couple of weeks. It has become annoying.

Does any RX450h owner or other Lexus car owner has experienced the same issue?

Can anyone advise what could be the causes for this rattle noise?

Many thanks.

In such a new, low mileage car it’s hard to believe it could be wear in the steering or suspension systems.  It might be worth checking all the wheel nuts - they have been known to loosen.

But it could be almost any fixing that’s vibrating when the car reacts to a rough surface.

I presume it’s still under Warranty, so it might be best to take it back to the Dealer to resolve.
