As I was driving, , I suddenly heard a very loud noise. I didn’t know what it was till I was going to turn to look at the side view mirror of any cars or pedestrians passing. Then only I realized it was my right view mirror that suddenly blew up.. I was lucky that it didn’t blew up in crosswalk where people were standing or waiting to cross because the fragments could have hit anyone..
Driver side mirror shakes when traveling on highway, making it difficult to see other vehicles clearly in blindspots. Manufacture closed case saying they called the dealership and my mirror doesn't shake any more than other models. Dealership confirmed most of the nx300 mirrors side view mirrors shake on the highway. Toyota has fixed their rav 4 mirrors, Lexus doesn't have a fix, and doesn't seem interested in finding one. The faster you go over 55 mph the more the side mirror shakes. The jiggle is about half an inch of movement, and a vibrating mirror makes it difficult to tell the difference between cars and other objects .
