I own a new 2013 Toyota Prius V-5. while on the freeway taking an interchange. I had cruise control set at 65 mph, disengaging it as I approached the interchange that slows to 35 mph due to the curve. I was coasting when the car suddenly brake, internal warning light flashing, alarm beeping and seat belt locked up. I was alone in the car (thank god) with no cars behind me or in front of me. It was an extremely windy day and was told by Toyota that it is possible something blew in front of the sensor. That in itself is another safety issue. Can I not drive my car on a windy, rainy or snowy day, in fear of the pre collision system misinterpreting what is in front of the sensor" I immediately took the car to the dealership only to be told today that they couldn't find anything wrong and that I am more than welcome to take a drive with their technician to see if I can replicate what had occurred. I inquired if the edr had recorded the event and they told me no. Is there something wrong with the edr? shouldn't it have recorded something like that" I can't understand why the pre-collision system (pcs) would act as if it were trying to prepare for impact if there was nothing if front of the vehicle. I could have been rear ended or lost control of the vehicle. This is a serious safety issue.
