Mine's not Quiet
 After a year of research and test driving various SUVs and crossovers we settled on the HH and decided to order exactly what we wanted.  We had test driven several HH and other hybrids and all were quiet, but none impressed us like the HH. When our HH came in we were excited.  It was beautiful and had everything we wanted, except for the NOISE! When we brake to slow down it sounds like a jet engine winding down.  It also has a click.  We were expecting the quiet we had experienced with the other HHs we drove, but were greatly disappointed.  The dealership has told us that some hybrids have that noise more than others - it is normal.  I won't order again.  I buy what I test drive on the lot.
