After 5000 miles on my 2010 Edge I noticed a rattle coming from the sunroof area. I also noticed the sunshade was wrinkled. Took it to the dealer and it was there for one week! They told me they installed (3) three new sunshades and could not get rid of the wrinkle. They told me to "let it settle." They also told me that they could not duplicate the rattle. I went to the dealer and pick up the vehicle and before I could leave the lot i heard the rattle. I turned around and got the shop manager to take a ride with me. He heard it and could not believe they missed it. Well it's been (4) days in the shop since then and I have heard nothing. Nothing like riding around in a piece of cr*p rental car.
