I just took my 2005 Pruis to the dealer. I noted today when cleaning the fog lights that BOTH had one long crack in them.
I mentioned to the service manager that several people have noticed cracks in their fog lamps and he said he hadn't heard of a problem yet regarding them. BUT most of the Prius he's seen don't have fog lights.
He took a very LONG close look at both lamps and he thinks the cracks were NOT caused by any impact. the lights are still smooth on the surface and he could not find any sign that an impact cause this cracking. And both lights have similar cracks.
I am thinking that it might be caused by the heat generated against the glass surface and being hit by cold water. I remember having the lights on when I had the car washed at the automatic carwash the last time. I also remember checking the lamps and they were fine when "roadgoat" on priuschat.com posted a note about cracked fog lights back in January.
I suggest that everyone check their fog lights for this type of crack on the fog lights. I and others are suspecting that there is a problem with the material used in the the glass.
The dealer is replacing my fog lamps under warranty.
