The Power Step / Running Boards do not operate as intended, especially on the driver's side. They are not deploying or retracting as they should, possibly leading to personal injury, ie. spain ankles, injury to the knees, legs and or backs of individuals, who assume the Power Step has deployed before entering or exiting the vehicle. I am seeking a recall be established concerning this matter, and a class action suit against General Motors be developed immediately. I have had my vehicle inspected, at a dealership, as many owners have, with nothing being found. Only to leave in disgust, and have to live with this daily issue. Something needs to be done about this problem, these are some very expensive vehicles, and owners like myself should not have to deal with this persist issue.
