2019 Forester Sport A/T Fluid Temp

2019 Forester Sport, 56233k on the odometer. Randomly tonight after a 5 minute drive, while pulling into my driveway, the car started flashing the a/t fluid temp light. Absolutely no issues with anything transmission related before this. It would not go past neutral, no reverse or park, I had to use the emergency override to get it into park because parking it in neutral with the parking brake on just makes it beep endlessly at you. Had it towed to the dealership and I have the extended gold warranty so it'll be taken care of, but I cannot find reports of this happening to anyone else with the normal Google searches. Has anyone else experienced this?
