My 2012 Focus SE Hatchback with the sport appearance package has the "ZIG-ZAG" steering issue. It is quite severe. I have a large motor home that I would rather drive in a cross wind than this Focus at 60-65 mph. My dealer has diagnosed the problem and has a new steering gear on order - which has been on back order for over a month. Ford has even agreed to give me a loaner until the parts are available.
Natasha, this needs to be fixed ASAP. I bought this car for good fuel ecomony and a sporty feel. I can provide more information if needed.
I would content that this is a much more serious problem than is being discussed. I am not looking forward to when the weather gets snowy or icy. The car is a handful on dry, clean roads.
