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.
- The noise intermittently occurs only at a speed higher than 50mph.
- Although I'm not 100% sure, I mostly hear it when driving on certain highways/parkways. Again, the noise intermittently happens.
- 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.
