“The car had about 8000 miles on it. It was parked in Garage the night before. In the morning the outside temperature was 39F. During my 30 minutes driving, the front defrost was turned on. Afterwards it was parked on driveway and at that time the windshield was fine. 6 hours later, I noticed a spiderweb like crack under the camera section on the front windshield. The crack was about 11 inch long. It looks like the glass could not handle the temperature change.”

The vehicle was operating normally and was not involved in any sort of unusual maneuvering or crash. Upon taking it to the Toyota dealership it was found that glass did in fact detach on its own and needed to replace the entire mirror mechanism. …”

“The contact owns a 2020 Toyota Prius Prime. The contact stated that he purchased and installed a dashboard cover in the vehicle. The contact stated that while reversing, the dashboard cover shifted and blocked the sensor for the back over prevention camera, allowing the display screen to go dark, causing the vehicle to crash into a parked vehicle at approximately 2 MPH. The contact stated that the sensor was used to distinguish between daytime and nighttime driving and would dim or brighten the display screen as needed. A police report was not filed. …”
