Same issue on my 08 Legacy wagon. Right rear taillight was shorting feeding back into the system causing the problem. I was the second one in to the dealer in the last month. The first guy paid 3 hours labour....I paid 15 minutes. No problems after that. As well a friend of mine had the same problem with his 06 legacy and another friend had the same problem on his 11 forester. All fixed with the replacement of the taillights.
Check Engine Light on, Blinking Brake & Cruise Control Light & VDC Light On ???
