2017 Subaru Outback fuel system problems

I was pulling into a parking lot. The attendant told me to back our 2017 Outback into a spot running along a fence and row of trees. I pulled forward, put my foot on the brake to fully stop. I then moved from "drive" to "reverse". Immediately, the engine started to rev very loudly as if my foot was on the accelerator (it was not!). The accelerator seemingly went to the floor and within a few seconds our car was in reverse at high speed.

We were traveling on the interstate and the miles to go before needing fuel monitoring system said we had 60 miles of fuel left. When reached 30 miles of fuel left on the fuel monitoring system the car died as if we were out of gas. It would not start again until be put fuel in the tank. I feel this is a dangerous liability. It just so happened that we had taken an exit and couldn't even make it to the gas station we could see a 100 yards from the exit.
