I have a 2011 Explorer Limited 4x4. When I start the car a malfunction warning comes up - 1) Collision Warning Malfunction - after I noticed it I took to mechanic ad he replaced the sensor Now I am getting a 2) Collision warning disabled message and neither the Adaptive Cruise Control or Normal Cruise control will work and I am super frustrated. Does anyone know how to fix this problem? 3) Also my remote start is not working at all Any possible way to disconnect the ACC and Collision sensor and just use good ol regular cruise control? Please help me I am in tears, I am so discouraged. I've never bought a Ford and I tell you after this, I am done, I will never buy another Ford again. I bought this car used as is and checked it before buying and everything was fine, until about a week later. I bought it for the cruise control and 5000 lbs towing package but too afraid to do anything with it now.
