Brake Loud Noise problems of the 2018 Nissan Rogue

I was just leaving my job, and driving down a local, double yellow-lined road, doing about 35-40 mph, when my 2018 Nissan Rogue's automatic breaking system suddenly, and aggressively engaged, causing the entire vehicle to shudder, and make a horrible noise, along with flashing orange, triangle warning light. The terrifying part about it, was that there was absolutely nothing in front of me, and thankfully no one behind me. I pulled over, and had a small nervous breakdown. This is an extreme safety issue! I don't want to think about what could have happened, had I been on the expressway or had my daughter in the car, and there was an accident! Nissan should absolutely recall the cars affected by this! not just issue bulletins to dealership's. Unacceptable. I'm calling the dealership tomorrow, to find out what can be done. Now, I'm afraid to drive my car.

I was traveling at about 35-40 mph on a city street when the vehicle suddenly stopped, and there was a loud noise around the right front wheel.

I was driving around 11am using local roads. I had been driving about 5 minutes when I pulled up to a stop sign. It was a clear day, light traffic, dry pavement, no leaves or other road debris. As I pulled away from the stop sign, within 20 feet, the car suddenly started shaking and stopping. It made an incredibly loud noise. I immediately pulled over the shoulder. There were no messages on the dash or behind the steering wheel. After sitting there a few minutes, I proceeded home without further incident. Later that day, I dropped the car off at the car dealer to check into this problem. I was given a loaner car, and by the following Monday, got a call to come and pick up my car. The service team was unable to replicate the problem, so nothing was fixed. This also happened on September 24, 2018. This time, I was exiting a highway and was slowing down on a ramp. The car suddenly started shaking and made a loud noise. It grinded to a stop. It was startling to me, as I've never had a car do this to me before. I assumed there was something wrong with the road surface and figured the anti-lock brake or the collision avoidance system had engaged. I was taking a friend home from cancer surgery that day, so I didn't think about it a whole lot. I had other worries. In considering what happened, I believe that the brakes automatically engaged in both cases. It seemed like the car was determined to stop, even though there were no obstacles in my way. I had no control over the car. It's an unnerving thing to have occur, but at least I was going slow and didn't have cars behind me. I'm concerned that if it happened as I'm going at a high rate of speed on a highway, it could cause a car to rear-end me, or cause my car to swerve out of control and cause an accident.
