“Driving home when I notice what I thought was a big hit the window. Slowed to the light and I notice it was actually a small round crack in my glass so I pull in the walgreens lot to see what could of happen. By the time I parked and opened my door I saw the crack had made its way all the way down my window, so I left the door open to see if I could feel the crack but nothing. I get back in lightly closing my door to head 2more miles to my home and the crack made it's way up half way then across half way. My heart literally melted. Why is this happening. …”
NHTSA complaint #11414047, filed 2021-04, 22,000 miles“Crack appeared in front windshield on passenger side at approximately mid-height on the windshield. No sign of impact from foreign object and vehicle had not been driven for 2 days before the crack was noticed. Crack originated from the very edge of the seal and spread over the next couple weeks.”
NHTSA complaint #11403733, filed 2021-03, 6,750 miles“Windshield spontaneously cracked at top. I came outside in the morning after a temperature fluctuation and there was a crack at the top with one piece of the glass sitting lower… it has since grown. I have been forced to drive with the crack as Subaru will do anything to not honor a warranty, ever. The eyesight I am learning is necessary for the vehicle to avoid front end collisions and to properly deploy the airbag. The crack started in November, it’s almost August, and I cannot get it replaced under the warranty I paid. I see many people have the same problem. …”

NHTSA complaint #11520756, filed 2023-05“Since last October when a software update was performed on the vehicle I have had multiple(8-10) instances where the EyeSight system caused the emergency braking to activate when no other vehicles were nearby and a crash was not imminent. Usually it has been when entering a left hand gentle curve with a guardrail nearby, but it has also happened going straight ahead. The audible and visual alerts appear and hard braking occurs. The braking is severe enough that on rain or snow covered roads a crash might occur. …”
