Looks like this problem is still not resolved, Ford is scratching for a fix, and more of the entire population of Edges may be affected. At 13 K, Ford went into the engine, replacing all the variable cam timing hardware. At 15K, the proble is back along with a whirling noise when the car is cold. The dealership is in contact with the Ford help line, which claims some new designed part is on the way. My honey talked about the lemon law, but the service manager said this problem may effect all vehicles. Sorry I can't be more specific on the parts already changed & the new parts on the way. She has all the paperwork at her place, and I never talked to the service manager. I told her, one more chance to fix this issue, and then she should start thinking "buy back". We'll see. Later, FJK
