all of you with the V open the hood and look at the coolant recovery tank and follow the hose down to the T and check to see if you have a hose clamp on the hose that comes from the recovery tank, if not put one on. This hose connection sees upwards of 15 PSI and could easily blow off in hot climates with the loss of engine coolant. I hate to say it but this will probably turn into a recall. I checked 3 new Prius today and non had a clamp on the hose. All the other arms of the T have clamps except the one to the recovery tank.
