Driving Ford Escape 2009 at consistent highway speed for approximately 20 minutes. Iphone plugged into usb port, head lights, air conditioning on and working. Sudden feeling of hesitation and then floating. Orange wrench light appeared. Sudden loss of RPM's and engine power. Semi-truck behind me weaved into other lane. I activated hazard lights and coasted/changed lanes over 3 lanes of highway traffic to shoulder of expressway. Stopped and parked car. Wrench light remained on. Air conditioning, music, and lights remained working. I looked up code in owner's manual and found "powertrain" "service immediately". I turned off car. I turned off air conditioning, unplugged iphone, music, and lights. I restarted car. Car immediately restarted with no warning light. With car in park, tested acceleration, no hesitation with rpms. I turned off car and waited 5 minutes. I turned car back on, again no wrench light, no hesitation with RPM/gas pedal tested. I turned off hazards and attempted to drive. No further problem driving that night or the next day. On Monday I took car to Ford dealership for inspection. I was called and told that battery needed replacement. I explained I was concerned because there was no loss of auxiliary power, rather engine power. The service representative stated they would replace battery at my agreement and continue testing. I was called later in day an notified that there was nothing wrong with my car. While waiting for call from dealer, I "googled" Ford Escape 2009 wrench light. I found multiple problems attributed to throttle body sticking, with inability of Ford dealers able to identify this recurrent problem. My car remains at dealer. I called Ford dealer again today and was told my car was fine to drive. I am concerned to drive this vehicle on any street/expressway with the potential for this to happen again, as reported by other drivers.
