Howling/humming Noise From Front Right Side

[hmkim]

I occasionally hear a low pitched howling/humming noise from the front right side of my 3 week old

2006 ES330.

Here's what I've observed.

1. The noise intermittently occurs only at a speed higher than 50mph.

2. Although I'm not 100% sure, I mostly hear it when driving on

certain highways/parkways. Again, the noise intermittently happens.

3. It's coming from either the right side of the engine compartment or the front right wheel. It's hard to tell.

I've been driving for more than 20 years and never heard such a

noise before. What do you think? I want to get a sense of what's happening before going to my dealer.

Have a passenger ride with you to try & isolate the problem to a specific area.......failing that, do the same with either the Service manager or advisor from you Lexus dealer. B) Good news is the car is under full factory warranty. ;)
