NHTSA Complaint #11425944 — 2018 TOYOTA PRIUS PRIME

From the first week of ownership sensors would alarm that they needed cleaning but they were clean. Parking assist sensors also malfunctioning. Also saw Intelligent Clearance Sonar error messages and warnings. Alarm tended to go off in wet weather. Brought to dealership many times and problem occurred infrequently that no problem was ever found. For two years I was plagued by alarms of sensor malfunction. I worried the sensors would fail to detect cars and objects in front of, behind or on the side of the car. That would be a serious failure and cause of an accident. After two years of unsuccessful testing, I traded in the car.
