A few days ago, a crack suddenly appeared in the windshield. It appeared when the car was parked in the garage. I reached out to SUbaru and they wanted me to take it to dealtership and get pictures taken. So, i complied and pictures were taken. The cause was given as a less than a mm speckk hitting about 1 inch or so above from dash. Area where glass is supposed to be strongest. I repeat, the cause was less than a mm sized dust particle. The vehicle was driven on paved roads, within city at a max speed of 60 miles per hour. MY concen is that when such a small speck can cause a crack, what is to say a 5 mm particle will not blow the windshield on my face. This is a serious quality concern and I am afraid to drive Subaru with Subaru parts in it. ALl while it is advertised as rugged off road vehicle. …
My windshield appeared to crack for no reason. The crack randomly appeared one day without a corresponding incident (no previous chips/crack in that area and nothing hitting my windshield). The crack began on the edge of the windshield in the upper corner on the passenger side and has continued to spread. There is no mark or indication in that area that the windshield was hit. The dealership mentioned when I purchased the car that I should get the windshield warranty due to an excessive amount of windshield cracking in my area. They claimed Subaru even did an investigation into Subaru vehicles in Michigan due to the high windshield replacement rate. It appears to be a defective windshield that the company is aware of and not recalling. The crack has spread across 80% of the windshield at eye level. …
On 10/9/2021the front windshield was hit by a small rock on the lower left driver's side and a crack developed within a few minutes. The crack grew and obstructed the driver's field of vision. This required the entire windshield being replaced. This was done by Safelite AutoGlass on 9/13/2021 at my residence. It was paid by my insurance and I paid a $100 deductible. In addition the replacement windshield was damaged by another small rock hitting it on I71 north near Louisville KY. This time the damage was limited to a bulls eye fracture. This was repaired by myself using a Rainx windshield repair kit. The windshield seems very fragile and prone to be damaged easily as both "rock his" did not seem that bad and should not have caused damage. I found after this repair that there are additional complaints and a class action lawsuit for similar problems with this vehicle.
