2010 ford flex limited ecoboost awd. Electrical power steering. Intermittent loss of power steering with no lights, notifications, or warning. Fixed short term by turning car off and back on again. Very dangerous at low speeds, especially with the weight of the vehicle and size of the tires, specifically for smaller people. Recall from ford for 2011, will not help at all with a 2010 flex. Has already caused one accident in a parking lot resulting in damage to rear driver side quarter panel after steering wheel became stuck while reversing. Fuel pump also not engaging, resulting in stalls and the car not starting (no ticks, humming, buzzing, lights and radio work). Overall, a very dangerous combination if they were to occur simultaneously, especially at speed. Car was purchased around 1 1/2- 2 months ago. Both issues are becoming more and more frequent.

Engine stalls out, while driving the car around town. Has occurred twice, separated by a few weeks. No warning, or engine trouble or indicator lights prior or after the event. Occurs while driving a low to moderate speed both times, about 30 MPH. Car can be restarted immediately after and drives fine. Have had mechanics check fuel and air sensors and lines and find no obvious defects. Other ford flex owners report similar problem since 2009. Rumor is that replacing the throttle body corrects the issue.
