I have a 2001 Outback that needed new front pads at 20,000 miles, new rear pads at 22,000 miles. It needs new front pads again at 35,000 miles! I know brake pads should last much longer than that. Has anyone else had the same problem? Subaru of America says that 15 - 20,000 miles is normal and will not admit to a design problem.
