The Driver Side Rear View when I started the Car back in January of 2024 after car had been running for 30 Seconds smoke and Fire flames were seen coming through that rear view mirror immediately contacted Subaru of America and was called back with urgency and they fixed this issue but since then I haves a few other issues I believe relate to the wiring inside the vehicle and due to the wiring, which caused the fire.
