Mysterious Lines on Inside of Windshield

A week or so ago, I noticed what looked like a short thin line of “reflection†on my front windshield just to the driver’s side of center about a foot or so up from the dash. At first I thought it was a reflection or something on the windshield. It was most noticeable in full sun – had kind of a “prism†like look to it. In last couple of days, there is another line to the passenger side of center, about same height above the dash. They are both about an inch in length and not conected (they are 3-4 inches apart). The driver side one is pretty straight and runs horizontal. The passenger side one curves upward from horizontal. If you run your fingernail across them, you can actually feel the lines (on inside of the windshield). The lines appear to have some depth to them – they appear to go “into†the glass, not just a surface scratch. If I thought a photo would show them, I would attach one but you have to get at just the right angle in the light to see them and I’m not that good of a photographer.

I have 2700 miles on the C and have had nothing impact the windshield. At lunch today, I stopped by my dealership and they could see and feel the scratches. I’ve been asked to come back tomorrow and let the service manager take a look.

I am using a Prius c Heatshield window shade but have felt around the surface of it and can find nothing that could cause this. Besides, I would hope the glass would be hard enough that a window shade could not damage the inside surface.

Anyone seen anything like this before (on either a C or another Prius model)?

I’m assuming the dealer will handle this without a problem, but am curious if anyone else has run into something like this?

 

Thanks ewaboy,

I had read that post earlier. At this point I'm not really sure exactly what I'm dealing with. Not like any windshield crack I've seen. These seem to be more on the inside of the windshield surface. I can "feel" the lines on the inside but not on the outside surface.

Just curious if anyone had seen something like this before. I'll see what my dealership's service manager says tomorrow......

 

The dealership is bringing in someone week after next to take a look at the lines to see if they are scratches or some type of cracks and if they can be repaired.

I'll update again afterwards.

Thanks
