It was raining. The adaptive cruise control was engaged. The system did not sense the car in front and keeps moving at set speed. It happen at least three times during the trip. I have to disengage the cruise control or hit the brake to keep the car from hitting the car in front. I looked at the in car cruise control monitor. It did not detected any car in front. Even thought there was a car in front. In my previous car with adaptive cruise control. If weather was preventing the safety system from operating normally. A warning would pop up and disengage the adaptive cruise control. No such warning with the Corolla. The adaptive cruise control seems to be operating normally once the rain has lighten up.
