Rattles front and back
 Since having my vehicle, my first Toyota, it has been into the dealership over 10 times. A few of my visits have been ones where the car was kept overnight.  Why? Dash rattles, trim rattles, windshield rattles that just keep coming back. The dealer has replaced many parts but yet has found a "cure" that lasts over two weeks. That is up front!!!  Body rattles in the back  were finally eliminated by epoxy caulk after many visits.  Both the windshield and back windows have been replaced to try to quiet the rattles.  The dealership has been diligent and professional.  I have had many vehicles over the years, new and old, but never one with such rattles that persist.
