The truck shuts off while driving which disables the power steering, engine and power braking. The electrical systems seems to reboot and turn back on after a second or two. This also happens occasionally while driving at slower speeds and turning the steering wheel or after hitting the turn signal. I have had the entire electrical system and engine shut off while doing 50mph on the high just because I turned my turn signal on. This happens every 4 weeks or so. You can tell it is about to happen when the headlights start deeming when tapping the brakes or using the turn signal. It usually happens when the truck is in motion. It has happened in all temperatures. After it happens the console states "stablitrak is disabled".

While tapping the brakes, the vehicle's headlights will dim. Occasionally, while tapping the brakes, the entire dashboard (including the touchscreen) turn off and restart. On 6/18/18, while travelling on a highway at 40 miles an hour and approaching a red light, I applied the brakes and the entire car shut down, including the power steering, power brakes, and engine. I had to place the car into neutral and turn it back on in order to brake in time.
While tapping the brakes, the vehicle's headlights will dim occasionally. 2 times now while tapping the brakes, the entire dashboard (including the touchscreen) turn off and restart. The first time was travelling on a highway and the second time was on my driveway, I applied the brakes and the entire car shut down, including the power steering, power brakes, and engine. That time I rolled out of my driveway and into the road. I was lucky no one was coming.
