My wife was picking up our daughter from school and had to circle the block several times. Around the fourth time, our new Prius's system warning light went on and the computer asked my wife not to drive the car anymore. My wife called the dealer and they sent someone to get the car. When they lifted the car they saw that the coolant had leaked. This sounds pretty close to what was described for the service campaign (Toyota to Correct Flaw in Prius Exhaust Systems - Driver's Seat - WSJ) Later that day the dealer said to my wife that a "rock had hit the radiator". I found this bogus at best and decided to contact Toyota directly. They initially did not know about this service campaign, after they looked it up they said that my VIN was not on the list and that they were not going to do anything. I asked them to contact the dealer and make them aware of this service campaign, and they agreed to it. Going around the block should not cause a rock to hit the radiator with such force as to make a hole ! I am out of the country right now and my wife has to deal with this alone. We are running out of options. Does anyone have any suggestions? Thanks !
