According to repairman, water made it into the rear tail light, shorting out a module that controls all lights, windows, a/c and heating controls.
Taillight leaks water causing the blindspot sensor to burn up. Once the sensor is burned up the airbags, power door locks, power windows, heat/defrost, and the radio don't work. This is a known problem and Ford has no fix for it. It is several weeks wait to get it into Ford and costs several thousand dollars for a known problem that they are not addressing. Having no heat or defrosters in the winter make this a safety issue for everyone on the road not just the operator. Door locks and windows not working is a safety issue for the vehicle passengers.
I was driving on the highway at 65 mph. A warning light came on saying my driver's side blind spot warning was not working. Then immediately a warning light with a wrench came on and said that there was a problem with the transmission. Then my truck shut down completely. It is not able to start, and the Ford dealer says they have no idea why.
