I was driving down the road and I heard a sound, and then saw a 5 inch horizontal crack, starting at the left side of the windshield and then it turned 1 inch up.... It was just above the inspection sticker. I did not hear anything hit but heard a sound. Both surfaces, inside and outside of the glass are smooth. I cannot feel any crack but can see it. I had my defroster on and it was sporadically raining and sleeting. I will be getting it repaired. Through Subaru's "goodwill program" vehicle was repaired.

Worked with insurance company to replace it with a Subaru windshield at an authorized glass replacement business. Windshield cracked again in Jan. 2022. Haven't owned this a year yet. -My safety and that of my family is at risk because this glass breaks easily and I feel unsafe driving it while working to get it fixed AGAIN. -There are known windshield problems with recent Forester, Outback, and Legacy models and pending litigation, but not on 2021 model years yet.

The component that failed is the windshield. The windshield has a 14 inch stress crack. The crack suddenly appeared, there was no impact. The crack interferes with the Subaru Eyesight Driver Assistance. The Subaru Eyesight Driver Assistance could malfunction while driving. The integrity of the windshield has been compromised. I brought the car to the Subaru dealership and they said it was not covered under warranty even though the car only has 6,000 miles on it. The Subaru dealership said they took pictures of the windshield and submitted them to Subaru of America. Subaru of America will not replace the windshield. According to Subaru when the windshield is replaced the Eyesight Driver Assistance must be recalibrated adding an additional expense.

Battery died completely, left me stranded at a gas station. I had to call and get a jump. I've had the car 9 weeks, it only has 690 miles on it. No warning lights prior, did notice a slightly longer crank a couple days prior. I was told by the dealer that I don't drive enough, and I should keep my key at least 30 feet away when the keys are in the house, because that can silently drain the battery. I had not left any lights on or had done anything to drain the battery prior to this occurring. I drove to the gas station with no problem, upon restarting after getting gas, no power, car was dead. I couldn't even move the shifter knob into neutral.

There seems to be an issue with the infotainment system. The system will randomly turn off which also turns off the safety features. I would like to associate this while CarPlay is in use, but I have witnessed it happen without CarPlay. Subaru has already replaced the head unit under warranty, but the problem continues. For the cost of the car, this should not be an issue.
