My 2007 Ford Edge just had a major engine failue with 91K miles. I was driving on a major roadway when I began to hear a tapping noise. Before I could take action the engine icon appeared in the dash. Whithin minutes the engine stopped and I was fortunate to have been able to pull off the road.
Bottom line: engine failure. Vehicle always properly maintained all fluid levels correct. Ford refuses to offer any assistance. New engine $7000 plus! This is after spending $1100 on a "common" transmission problem 6 months ago!
