 Only have 1300 miles on the car and the car started to have 2 major problems. The first is when you reach speeds of 50mph or greater the car vibrates and gets worse the faster you drive. The second is the shifting makes metal pinging noise. I have been at the dealer twice so far and they still have not fixed either problem. I am bringing the car back to the dealers again and I do not have much confidence that they will get it fixed. I have looked into these 2 problems and it seems that a lot of Mustang owners have the same problems without having their car fixed. I hope Edmunds reads this and looks into these problems. If anyone reading this and has these problems, please let Edmunds know and maybe they can help us out.
