Just purchased this vehicle certified pre-owned 2 months ago. Car was parked and spontaneous windshield crack started on drivers' side and has now advanced up through drivers visual field. A simple google search shows this to be a chronic, documented issue with MANY Subaru vehicles. Driving is limited and this is a costly fix for a fault not on the consumers end. I have contacted warranty and consumer protection before I call to schedule a replacement. ZERO problems or damage to vehicle before this, car wasn't in motion and as evidenced by photos it had no physical compromise causing this.
I have has to replace the windshield 3 times in less than 3 years in my 2021 Outback. Only once was there a definite impact from a rock. In that case, the glass broke in 5 directions across the entire windshield. The other two times, I simply woke up to a huge crack. It seems that this is an extremely common problem with this mo…

I have has to replace the windshield 3 times in less than 3 years in my 2021 Outback. Only once was there a definite impact from a rock. In that case, the glass broke in 5 directions across the entire windshield. The other two times, I simply woke up to a huge crack. It seems that this is an extremely common problem with this model, and my insurance says they will drop me if I continue to make claims at this rate.
Window cracked when hitting by a small chip on the high way
Went out to car and windshield had a 6 inch horizontal crack in the beginning at the center of the frame the passenger side extending towards the driver side. There was no chip or point of impact noted. Appears faulty placement of windshield like on prior model class action.
When driving on Interstate Highway 44 at approximately 45mph the windshield suddenly cracked on the lower passenger side of the vehicle. There was minimal traffic at the time of the incident and the roadway ahead was clear.
Windshield spontaneously cracked. There is no obvious sign of impact from an external object, verified by location replacing the glass. This is the second windshield that has spontaneously cracked in less than a year's time.
Have owned the vehicle less than a year and it has already acquired 2 chips. One of the chips spread out to a larger crack immediately.
My windshield has cracked 3 times since vehicle was purchased, the last time within 2 months of replacement. The first 2 times the windshield was replaced by the dealership with OEM glass. There was no visible crack from rocks, etc in the last two incidences...went out in the morning to find that the windshield was cracked acros…

There was no visible crack from rocks, etc in the last two incidences...went out in the morning to find that the windshield was cracked across half the windshield after it had been parked and no visible damage had occured beforehand in both cases. ( I have taken pictures of this last incident... insurance notified, but no inspections took place. no warning lights, etc appeared pryor to cracks)
