Q: My 2014 Ford Fusion sometimes won't start & gives me error codes for it overheating & service the advanced traction control.

Hi There, It sounds like you may have a couple of things that may be unrelated. The advanced traction control is nothing more than your vehicles traction control system. Your car is equipped with wheel speed sensors at each of the four wheels which monitor wheel speed while relaying this information simultaneously to the ABS and traction control system which are controlled by the car’s ECU. When the ECU senses an abnormal speed given specific conditions, it engages the ABS or traction control as needed to control the vehicle properly and safely. Occasionally, these sensors can fail or become faulty working intermittently sending inaccurate signals to the ECU. When this happens, you may experience the symptoms you have described. The ABS or traction control system may be inadvertently activated by these false or inaccurate signals.

Your temperature sensor is likely faulty which may be what is causing the temperature light to come on after the vehicle has been sitting for an extended period of time. I would suggest having a professional from YourMechanic come to your location to diagnose and inspect your vehicle.
