I have the same leak (and same car color) as this google hit: https://attachments.priuschat.com/attachment-files/2016/01/99777_Gen_2_Prius_Water_Leak.pdf Anybody else can also advise? Thanks. Too dark outside right now.
Sorry, wanted to know to make it go away. My priuschat research suggests I should just apply sealant on problem spots until the problem goes away. I am not good at seeing cracks... it all looks uncracked to me.
Very common to have a leak at the upper left corner where two seams meet near the left rain gutter trim. Take a pic an post here.
