I take my 2012 GT in this coming Wednesday to have glass replaced, which was my dealers response when I complained about the vibration during a service visit two weeks ago. We'll see....
You know, I love Mazda vehicles, but the one thing they can learn from Toyota and Honda is how to design a vibration-free mirror glass.
Mine's not that bad either, but every other vehicle I've driven in the last 10-12 years had steady mirror glass through the entire rpm range and in all wind and road conditions. Not like it's out-of-reach technology.
And, I bet every single CX-9 manufactured to date suffers from the issue to one degree or another. Shame is Mazda doesn't give a rat's ass. They train the service managers to look at you like you're crazy when you seek remedy for a legitimate issue.
I have always wondered what that annoying vibrating noise was. I thought i popped a speaker because I enjoy blasting my rap music. So all this time its our side mirrors?
I just picked up a 2014. On the drive home I notice the driver side vibration. Next day I go back to dealer and tell service writer the problem. He looks me dead in the eye and says "I know, we don't have a fix for it, maybe by the time you bring it in for the 30 day lookover we will have a fix from Mazda" I will be doing my homework and going back in 30 days loaded for bear.
Yes, my dealer has me bringing in the car after 30 days to give it an inspection and address any issues. Took it on a trip to pick up junior at college yesterday and it ran beautifully, except for the mirror. 60 mph is the starting speed for the vibration.
