Sounds like Sakumar and I have the same experience. But most others do not. Perhaps it varies from vehicle to vehicle and we both ended up with noisy ones. The odd thing is that my husband, who drives a BMW, doesn't find the whine bothersome at all. He feels it is useful feedback that the regenerative system is working and it makes him feel virtuous. Yes, I know that the owner's manual says that noise from the brakes is not indicative of a problem. But they are talking about a mechanical problem. I don't think the car has a mechanical problem I just think the sound is unpleasant. Otherwise I love the car. So I guess I'll drive it for a while and see if the noise gets fainter (or that I get used to it). If not I'll bring it up at my first service and see if there are any adjustments that can be made.

I just took delivery of a silver RX400h yesterday. I test drove the model in Colorado a couple of months ago and loved it. But the particular car I ended up with turns out to have a very noticeable and annoying high pitched whine whenever the regenerative braking kicks in. I'm wondering what experience other drivers have had. Is my noise abnormally loud or is it normal? Can it be tuned down in the shop? Does it get better as the car gets driven? Or do you just have to get used to it? I certainly don't remember anything like it on the car I drove in Colorado. There may have been a soft whirr, but nothing like this. The two standard complaints about the RX400h seem to be that it doesn't get the EPA gas mileage (but no car ever does) and that the brakes can get weird if you hit a bump while using them. But so far I've not seen compaints on this forum about the car whining. Which is odd. Nobody likes to hear whining. Yes, I know I'm whining right now. Did I get a lemon?
