Cruise Control is just part of the issue. The truck seems to have an electrical demon or virus that is moving throughout all the electrical items- radio, speakers, batteries running down while parked and turned off, and now a death wobble which seems to be due to traction control which I would assume is electrical as well.

The cruse control does not work at different times when driving the vehicle. When on a long car drive, it may not work when we leave the house, but after turning it off at a rest stop and then starting up again, it will work once we get back on the hwy.

My cruise control is not working. I drove 1 mile from dealership and cruise control would not turn on. They tried replacing the speed sensor in rear end, the bushing on brake pedal, and the brake switch -- still did not solve the problem. Ford customer service told me that my cruise control does not replace my foot on the gas pedal.
