Noticed side view mirrors vibrate at speeds above 25 mph and on highway speeds. Driver side mirror has much noticeable vibration when looking at it to make lane changes. Vibration makes it hard to focus and view other vehicles on the road and possibly a safety concern. When taken to dealership, technician could not duplicate the concern and did not found mirror to be loose. I also noticed that tapping from inside the front driver or passenger door creates similar vibration of side mirrors. Both side mirror assemblies need more structural strengthening due to it-??s position on the door panel which is prone to vibrations from road and transmits it to the side mirror assemblies. This is a design defect that needs to be addressed.
