I have recently been having the same problem with my Ford 2013 C-Max Hybrid. Engine was running but no movement(propulsion) with the yellow wrench “see manual” sign. I took it in and they had no idea because the light was not actively on, but it constantly turns on though now after driving for 30 minutes. I thought it was overheating since it is now summer, but i’ve also surpassed 120,000 miles. Should I take it in and ask for a computer reboot? Or should I get a tow next time it happens and leave the engine on so they can know what the light means?
