It started with the dome light sometimes working and other times not,then the remote to open doors. I changed battery and fuse, did not help. So everything is locked and unlocked manually. Next it was the seat belt bell. It will go on when your driving when belt is on. Now it won't chime at all just the light flashes. Next it was the head lamps. Changed one, then immediately the other went out. The head lamps are not equal in positioning. And now the stereo only has the right side working (not sure if that's connected to electrical) it's been a nightmare. Today the dome light decided to work. I would never buy another Subaru again and want to spruce this one up an get rid of it.
