I don't post much here, usually just read through the threads. However I thought I should chime in here. My wife has an 07 Edge AWD with about 6,500 miles on it. Recently I have noticed a rubber burning smell on a few occasions. Each time, we have been driving for a little bit with the heat on (Winter in Central NY) and come to a stop when the smell is noticed. It doesn't last long or seem to affect the vehicle in any way. At first I wondered if the rear heat ducts were blocked by some of the baby stuff in the back but sometimes nothing is in the way. I'd be interested to hear what anyone else finds out. Since it doesn't seem major, I'll wait until the next oil change. I did notice a TSB on NHTSA's website that talked about brakes dragging and causing a smell... not sure if this is related. The smell is only noticable inside the vehicle and no smoke at all.
Otherwise no issues and we love our Edge. :shades:
