No rattling. sounds like bearing failure noise but it disappears and sometimes no noise whatsoever. Toyota worked on it for a day they heard the noise but they couldn't locate the source of the noise.

You could try a different dealership to see if you can get a better result or try a decent independent http://www.boschcarservice.com that could be the better option as you can talk to the mechanic who has listened to the noise.

Customer: replied 18 days ago.
further investigation: when the car runs on battery there is no noise once the battery drops off the noise can be heard for a while and than goes silence again.
Expert:  Gavin Perry replied 17 days ago.

I can not hear the noise so as i said take it back to the dealer or use an independent http://www.boschcarservice.com
