Brake Sensor problems of the 2018 Acura MDX

While driving downhill a car approx 1000 feet ahead of me was slowing down to turn right while the car was still turning but completely out of the intersection the automatic brakes came on and came to a complete stop. The car that turned right was down the street it had turned on completely out of sensor range and the automatic brakes would not let off, when trying to accelerate it got stuck in gear but would not budge. Like when you dont shift a gear for too long in a stick shift car. Finally the brakes let off and I was able to drive but further down the same hill the automatic brakes did the same thing again while trying to accelerate to change lanes, there was not a single car infront of me at this point and no reason for the automatic brakes to do this. Both incidents almost caused me to be rear ended.
