Windshield cracked from the side without provocation. Its possible a pebble caused it, but a very small pebble as I never heard any rocks hit the window.

Prius windshield is prone to crack when traveling on highway. I was traveling on highway when a tiny rock hit the lower right side of my windshield. Then I could see the tiny crack getting longer until it nearly reached the middle in a matter of two minutes. Prius owner should not have to put up with this expensive and dangerous defect.

I closed the trunk door, and the back light glass (rear window) completely shattered. When this occurred, the glass was not cracked and we were not in extreme temperatures (it was about 65 degrees). I took it to the Toyota dealership, and the service guy said it's "impossible" for the glass to break as it did. It's obviously not impossible if it can happen with normal closing of the trunk door. Vehicle was purchased new less than a year ago.

There is a visibility issue on both the right hand and left hand side of the windshield. The right hand side has a glare/blurry effect when making turns. The left side had some sort of circular effect that negatively effects my vision. The dealer attempted to treat the windshield with rain X as some sort of fix. This did not help. This was a very unprofessional fix. In fact, I believe the rain X made the problem worse. I don't remember the issue occurring until a few weeks after the initial purchase of the vehicle.

Point sources of light (I.e. brake lights, headlights, traffic lights, etc.) at night time and to a less visible extent in the day time are duplicated or triplicated at distances through the front windshield. As the light source is closer to the car, the ghosting effect diminishes. This problem does not occur when looking out the side windows or rear windshield, but only occurs through the front windshield. This prism effect induces nausea and is incredibly distracting while driving.

- Pasadena, CA, USA

Windshields on Prius models 2010 and higher are affected. While most obvious at night, external light sources viewed through the front windshield can be mirrored in triplicate via a "prism" or "refraction" effect. Interior occupants will witness light sources being replicated 3 times. The resulting effect can create nausea or dizziness in occupants, and is experienced with maximum effect at night during traffic when the ability to safely negotiate roadways is paramount.
