My wife's '07 Edge has a couple of problems. We've been to the local dealer twice in the last six months for front end issues, so we're hesitant to take it back there, and wondered if anyone out here might be of some help. Both issues related to when the engine is cold; First one being a loud hissing/squeaking noise coming from the engine compartment, but it is at its loudest on the passenger side, with the noise coming through the tire/rim. Its most prevalent when the engine is cold, and when there is a lot of humidity and moisture in the air. I thought it may have been an exhaust leak, or maybe a bad gasket, because as you drive down the road the rate of the hissing sound is consistent with the RPM, but when the sounds goes away after the engine heats up, I ruled that out. I thought maybe it sounded like a pulley, or belt going bad?
Other problem always seems to come from the passenger side on the front, and again, only when the car is cold. When we leave for work in the morning, and we back out of the driveway, we hit the brakes to look for traffic, and when we do, there is an incredible grinding noise coming from up there. Then, when we reach the end of our neighborhood, and apply the brakes again, same noise. These are the only two times it makes the noise, by the time we are hitting them again, the engine/car has warmed up and all seems to be fine. Both times we've had the car into the dealership they have said the brakes are fine. We are at a loss!
May I pass on a suggestion? If the dealer is telling you the brakes are fine, chances are they really are fine. They stand to make a profit by telling you they are bad and getting you to authorize the work if so. Just by what you describe tells me there really isn't anything to worry about. As a dealer tech, I haven't really seen any common issues with this vehicle myself, so if the dealer is telling you it's okay, don't call them out on it and leave it at that.

The hissing from the passenger side is the condenser. Prior to buying mine, I noticed that all of them I test drove did this when cold. I have 80k on mine now and it still does it, so I would say its normal. As for the brakes, not sure.
