 In May 2018 rented a 2017 Toyota Prius Three with Technology Package (Heads Up Display (HUD), moon roof, satelite radio) for one-week of long distance and local travel from local dealership.  I planned on purchasing a Prius so thought this would be a good way to see if I liked it.  Last day of rental a rock hit windshield and created a small hole, less than the size of a dime.  Returned to dealership where it was rented and they stated windshield needed to be replaced.   Estimate from dealership to replace windshield is $850.00 from their vendor, $1,400.00 from Toyota parts department.  Researched the issue and apparently there is a class action lawsuit against Toyota due to faulty windshields on 2016/2017 Toyota Prius's.  Not sure if issue was corrected for 2018 models.  Apparently if a vehicle has the HUD you cannot replace it with a regular windshield, it must be a certain type of windshield that has a film on the interior side of the windshield for HUD to display.  Highly recommend you do your research on this vehicle and windshield issue prior to purchasing.  Online forums have stated Toyota dealerships will not replace faulty windshields even with vehicle under warranty.   Gas mileage was great at 65 MPG plus but not sure about reliablity of windshields.  Yes, some insurance companies will replace for no to low cost however after spending $20K plus for a vehicle is this something you really want to deal with?
