Something is fishy here... the dealer can install a recorder that will verify your complaint and save the codes when it occurs... also there is a lemon law that protects you as long as it's a same repair they have attempted 3 times without success... Ford hotline it's self would have helped...
Based on my reading I assumed this was the answer... I'm going to be adding he Steeda K brace underneath.... with the newly released jacking plates so I can store her on stands during the winter.
