I have not driven the 2015 Edge but I had the 2011 escape that I loved, that is once they got done j—— me around about the air conditioner! Now I have the 2018 Edge titanium 3.5L AWD and the vibration is terrible. Of course..”technician can not duplicate problem” and I was sent on my way. Although I love everything else about the car the vibration makes long distance driving miserable.My much less expensive escape rode better with 100,000 miles on it.
