Yesterday, I was driving my IS250 at over 100mph on I-5 North and from time to time, I heard some hitting maybe from rocks? on my left side mirror. If it was just once, I would of thought it would be a rock but kept making that sound. When I got off the freeway I checked to see if it was any rock chips but I couldn't find chips or dings. Is anyone experiencing this or is it just me?

Is your mirrior glass loose?

I might have check that... I don't think the mirror is loose tho... I've folded it couple of times due to parking outside on LA streets. I didn't fell anything being loose on the mirror. Hm..

you're not alone. I also heard it from the passenger mirror. nothing was loose.

Did you go at the speed or close to 100? Haven't heard it til yesterday..So I might be wrong. If your also experiencing it then.. maybe someone else might also.

when i go over bumps, thats when i hear it. not as often though
