broken side mirror
I actually forgot that I posted the issue with the broken side mirror, but just got a notification via email that someone had replied to my posting
To answer your questions, I live in Colorado Springs, CO and shuttle to and from Beaver Creek, Vail, Breckinridge, Keystone, and Copper ski resorts during the winter. I use the heated mirrors to melt the ice/snow during snow storms.
When I brought this to my dealer's attention, they replaced it under warranty. My MDX is at 30k now and I still love it.
