I purchased a 2020 Subaru Legacy Sport in March of 2020. On August 25th 2020, while on the freeway a small rock chipped the upper passenger side of the windshield. By the next morning it turned into a crack which spanned almost half of the windshield directly in front of the Eyesight cameras. Once the glass was replaced with an OEM windshield, I noticed the new glass appeared to have defects. During peak glare times, the windshield appeared "pitted" as if it had been sand-blasted and was nearly impossible to see out of. I had a professional technician inspect the windshield and a new one was ordered and installed. This took months to be resolved. Next was on July 15th 2021, a small rock caused a bullseye chip in my windshield too large to be fixed. Another OEM windshield was installed. …
This is in regard to the thin and fragile windshield subaru has decided to put into their vehicles of which there are already several civilian class action lawsuits which should have already warranted an investigation into the glass. In my particular case, the windshield is so soft whenever the slightest rock hits it, big chips come out of it. The vehicle has 5,100 miles on it and has a windshield that is worse than my 2007 subaru with 95,000 miles. Yesterday a small pebble struck the lower right corner of my windshield initially putting a chip that then cracked sitting in the garage overnight. In all my years I have had other strikes happen such as a huge rock falling off of a gravel truck (I have this on dash cam video) striking my windshield with minimal damage. …
2020 Subaru Legacy Touring XT - Windshield cracked for no apparent reason. No stone or rock chips visible. Had same issue on previously owned 2015 Subaru Legacy. The crack starts at the base of the passenger side where heat strips are located to keep the wiper blades from freezing. The cracked windshield may cause the Subaru EyeSight safety system to malfunction, putting all passengers at risk for a potential accident. I had it inspected at a Subaru dealership. The service technician confirmed that this was a know problem. He suggested I call Subaru of America for assistance. I'm still within the 3 year warranty period but windshields are not covered. He said Subaru dealerships do not repair windshields. They will engage a 3rd party repair shop if needed. My vehicle is included in a pending class action lawsuit against Subaru for this issue. …
