Loud humming sound from engine
I have an ES350 with about 4,000 miles. I have noticed that when I accelerate to 40-45 mph, and then release the gas pedal completely and coast, I notice a large vibrating, almost humming like sound from the engine. I didn't notice it before as I usually have my radio turned up, but I was driving the other day with nothing on and on a quiet road and noticed it. Has anyone else experienced this? Is it normal?

Doesn't sound normal. Do you feel it, too, or just hear it?
