2013 Ford Focus wheels problems

Steering and computer aided systems along with tires that were not disclosed to be used under 40 degrees caused loss of steering input and control which lead to hitting a curb and damaging suspension components as well as the drive-ability of the vehicle is worse that before. There are known issues with the steering on the 2013 focus st and after 6 months of going back and forth, ford cannot remedy the situation and the care is unsafe to drive at any speed as the lack of steering control cause unnecessary movement…

Vehicle was purchased brand new. Car handled erratically on wet / slick surfaces. Originally thought the problem was traction control related. Brought the car in for service and ford service (all american ford, hackensack, nj) said the traction control was operational. We specifically suggested it might be the tires, and ford service indicated the tires were not problematic / an issue (incompetence or disinterest). Subsequently learned that ford installed "summer only tires" instead of "all weather tires".
