Visibility/wiper complaints
97 reportsTiny spec of one sand grain instantly put a 14” crack across a windshield of a 2021 Subaru Outback I have pictures, how does a spec of sand crack a windshield?
Noticed a 6 inch crack on passenger side starting under the wiper. Crack started spreading across the windshield, now about 18 inches long.
Windshield has cracked for no reason. Heard a small cracking noise driving on the road. No accidents or anything, see a ding on the windshield and a crack growing after two days of parking in the garage.
The windshield cracked from the bottom corner and slowly spread across the entire windshield. I took a picture before replacing the windshield, a repair that cost ~$900 to replace and recalibrate the eyesight system.
My windshield cracked within a few months and few thousand miles of purchasing my vehicle for no real apparent reason.
We were literally sitting in the car, parked, and the lower left driver side windshield cracked! No visible chips. We will contact Subaru if America and out local dealership as well.
Upon entering my car I noticed a 7-8” crack on the driver side of my windshield. There was no evidence of anything chipping or causing the crack. It seems to be spontaneous. If the crack continues to spread it will affect visibility and the windshield cannot be replaced on site due to the forward facing camera and anti collisi…

Upon entering my car I noticed a 7-8” crack on the driver side of my windshield. There was no evidence of anything chipping or causing the crack. It seems to be spontaneous. If the crack continues to spread it will affect visibility and the windshield cannot be replaced on site due to the forward facing camera and anti collision system. I will have to drive over and hour to get it repaired. Also need wait for a new windshield to be in stock. I have submitted pictures to my insurance company.
The component that has failed twice is the windshield. They current windshield is available for inspection but not the first. In fact, I am taking it my Subaru dealer tomorrow so they can look at it. This is the second windshield in 13 months that has failed. The first one became heavily pitted across the entire windshield. Thi…

The component that has failed twice is the windshield. They current windshield is available for inspection but not the first. In fact, I am taking it my Subaru dealer tomorrow so they can look at it. This is the second windshield in 13 months that has failed. The first one became heavily pitted across the entire windshield. This one has a crack starting from the passenger side, 2/3 of the way up and then continues 1/3 of the way towards the driver. I do not recall any impact on the windshield prior to the crack occurring. I am concerned about the frequency of this model's windshield issues and whether it can stay intact. As noted above, this problem has happened twice for me. I posted my concerns on Reddit to see if other owners of this vehicle are having issues and I have received numerous responses that others are also having quality issues and those issues are similar to mine. There was no warning prior to the issues with my windshield. It is interesting to note that Subaru had a class action lawsuit against them just a few years ago related to this very same issue with the windshields. I am concerned that the windshield issues have not been adequately addressed.
Front Windshield crack so easily that I have to replace it two times already. The first time the windshield crack from using the defrost in the snow, and the second time was a small rock while I was driving on the highway. I've driven many cars in the past and have had rocks strike my windshield all the time and never experie…

Front Windshield crack so easily that I have to replace it two times already. The first time the windshield crack from using the defrost in the snow, and the second time was a small rock while I was driving on the highway. I've driven many cars in the past and have had rocks strike my windshield all the time and never experienced anything like this. I'm surprised the windshield recall isn't extended to the 2021 model Outback yet.
