Power Steering Failed problems of the 2017 Infiniti QX60

My car hydroplaned and everything shut off. The brakes and steering wheel locked and the engine shut off. There was nothing I could do to prevent the accident. I was driving under the speed limit and was not engaged in any reckless maneuvering. I felt the car slide in an unnatural direction and when I attempted to counter correct I found the steering wheel had locked. I next tried the brakes which were also unresponsive. The vehicle slide into the center divider on the freeway and I slowly rolled to a stop. Upon coming to a stop there was a strange odor in the cabin of the car, some sort of fume. I tried the gas peddle but the engine was unresponsive as well. I was pushed off the highway by highway patrol. When the tow company showed up, the driver of the tow truck was able to start my car by bypassing the systems ignition and jump-starting it, he then drove it up onto the tow truck bed without a problem. This tells me that the brakes, power steering and engine failure was not cause by the damage of the impact but rather that the car shut itself off in mid transit. I've contacted infinite and they are refusing to run a diagnostic on the electronics to find out the cause of the failure, so I am taking matters into my own hands. I'm grateful for the center wall divider or else the car would have slid into oncoming traffic! searching for insight and/or similar experiences form infinite car owners.
