I'm not english, so expressions like "whirring noise" doesn't give much meaning to me, but yes it may sound like a washing machine, or like if your front wheels touches the inner plastic covers of the car when they spin around and by that make a noise increasing in pitch with increasing speed.

Oh its not the dreaded washing machine noise is it?! 

What exactly do you mean? Have you experienced anything similar?

You might want to check if your new tyres are unidirectional tyres and if they are, that they have been mounted the right way round.

It may be a long shot as road holding would be impacted as well as rolling noise, but since the car is new to you, you may not have noticed a change in behavior.

Worth checking.

In my case the tires are mounted as they should be, with the "roatation" marks pointing the right way

Good that it is nothing wrong with the car. Tyres are easy to replace although it's an expensive you probably could do without. What model and size of tyres do you have, clearly they are ones to avoid?

I'm running brand new Michelin x-ice on 225/40R18. 17" would have minimized the noise from the tires, but I feel that the noise is a bit unusual coming from the tires, but I guess I just have to try to ignore it 

I had a mechanic at Toyota to check my car today and the (his) conclution is that the tires are causing the noise and that its nothing wrong with the car. I have to admit I also think that's whats causing the noise in my case, although I "hoped" it was something else. 

Well, in my case its not a vibration problem but rather an howling noise at certain speeds (50-60). It does not change with increasing og decreasing rpm. 

Hi!

I'm also having the same "problem". Just bought my 2014 Is300h a month ago. Not before recently I've notived noise from the car mainly around 50-60 km/h and espescially when slightly accelerating or decelerating. The noice is not depending on the rpm, but the speed of the car. I got the dealer to put on brand new michelin tires before I got it, and as far as I can see they are from 2016, so I dont think that bad tire quality is the reason. Just like you, I think it sounds more like the noise you have when a bearing has failed, but its the same either in corners or driving straight ahead, so the bearings should be ok. I might have a technician to look at it for me. I'll let you know the result if they find anything wrong,  but I'm afraid thats just how the car should be. 

Sorry for my "noobie" english, I'm not english 😀
