The vehicle was bought brand new and was only driven for a week. It was in motion on the freeway when the engine started to sound noisier than usual, like that of an older truck. It was hard to notice on higher speeds on the freeway, but upon slowing down on curves, it got more obvious that something was really wrong because the noise sounded like something was loose inside the engine. There was no 'check engine' light or any other warning lights. Upon exiting the freeway, the engine shut off completely while in motion. Fortunately, I was able to pull in a parking lot and park it safely. The engine would not start safely after that, and 'check engine' activated. The vehicle is currently being diagnosed at a dealership. Last update was that the engine was being taken apart completely because they said it's definitely inside it.

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.

I had to place the car into neutral and turn it back on in order to brake in time.

Reduced engine power, this has happened about 7 times. When this happens the engine shuts down to 1500 rpms maximum. Took to dealer, they told me that it was the throttle body valve and actuator assembly. This part was replaced at a cost of $481. Within two weeks the same problem has happened twice more. This is dangerous when traveling in traffic.
