Brake Light On problems of the 2019 Nissan Rogue

My automatic emergency brake light is flashing for no reason. Even if my window is clear, and there is no obstruction in front of me. And sometimes it is flashing, it just comes on and off again and again.

I was in the parking lot of a home depot. I turned right into an aisle where there were available spaces. As I approached a spot I took my foot off the accelerator to let the car slow down on its own and rested my foot on the brake pedal getting ready to apply the brake to bring it to a full stop once I was in the parking space. As I approached to space the car responded properly by slowing down. I turned left with my foot resting on the brake lightly pressing down getting ready to fully apply the brake for the final stop. However, as I pressed the brake the car kept rolling ahead on its own. I then pressed the brake pedal harder and harder but the car kept rolling and I pressed with all my strength on the brake pedal but it kept rolling, not stopping until it hit the parked car in front. There was no braking power at all. It appeared there was little damage to the other car, just some scratches and indenting of the area below the trunk lid. My car was damaged in the right front fender area with some bending at the headlight area. The fender is also misaligned with the hood. Although we drove it home, putting it in neutral whenever we were slowing down and applying the brakes we will not drive this car ever again. We will have it towed to the dealer. The car is equipped with automatic front braking, which obviously didn't function and it seems to have overridden my attempt to manually apply the brakes. We will have it towed to the dealer and want Nissan to refund our money. The car is about two months old with only a couple of thousand miles on it. At purchase the salesman said there were the equivalent of 17 laptop computers in the car. Maybe they should have less electronics and more reliability.
