I have a 2014 Ford Edge with 20K miles on it. I have been dealing with a chronic vibration (felt in the seat not in the steering wheel) for the past year and a half now. I can not pin point a pattern of any type, it appears to happen at random speeds, no rhyme or reason. I have taken this car to every tire shop around, every Ford dealer around, and no one can find the issue. I replaced the tires about a month ago because the Ford dealer said that needed to be the first place I start in order to find the issue. I have had the new tires balanced about 3 times now and still get a vibration. The interesting thing is that every place I go says that all the wheels are in great shape (no bends etc), but when they put the wheels on the balance machine, they balance out differently each time. For example I took it to a tire dealer in my area, they pulled all 4 wheels and put them on the balance machine. They spun each tire 4 times consecutively...3 of the wheels each time had a different reading on the balance machine..1 was perfect every time. This same thing has happened at multiple tires shops/dealers etc. No one can figure it out! Very frustrating!
Can anyone shed some light on this issue???
Thanks!!
