While driving on the expressway, multiple system warning lights suddenly appeared on the dash with the message 'engine failsafe mode'. The engine immediately shut off and I lost power steering and power brakes while moving at highway speed. I was able to coast to the shoulder and the truck would not restart. The vehicle ran perfectly prior to this malfunction and there was no warning that a problem may exist. A mechanic determined that the power control module (pcm) was corrupted and required reprogramming. I purchased a refurbished pcm and had it programmed by a locksmith to my VIN. The faulty pcm is still in my possession and available for inspection. This is a very dangerous condition that could have resulted in a crash. Fortunately, this malfunction occurred on a Saturday morning with light traffic during daylight hours. I am scared this will happen again in the future because the cause for the pcm failure is unknown. The towing fee, diagnosis and repair created a considerable financial expense on my behalf.
The two original vehicle dome lights in the overhead console assembly, Ford part no. :4l3z-18519a70-bag, have melted the plastic parts within the assembly increasing the chance of a fire.
