Just get back from another SC recommended from UMW.
Now they say the noise came from transmission, suspect fuel regulator giving out the whistling sound.
They check no defect and could not do anything.
Last answer, this is normal for this model.   

Great job UMW, you can't give solution and blame the design.
Does all car manufacturer does this?

Complain to Japan Toyota, and they redirect me back to UMW.
Even Japan Toyota lose hope on UMW now.
