We experienced brake failure twice on a trip 11/4/10 - 11/6/10. The first incident occurred on 11/4 while using cruise control. To slow for a vehicle in front of us, I hit the brake pedal. The brakes were not responsive and the cruise control remained active. Pumping the brake pedal in a few seconds deactivated the cruise control and the brakes returned. This occurred with a noticeable jerk. The second incident occurred 11/6 while on heading East on rt 30 coming down sidling hill. The cruise control was not in use. While attempting to brake to reduce speed going down the hill, the brakes completely failed. Repeated attempts to use the brake pedal failed to provide any braking. I used the parking brake to slow us down; however, the parking brake did not seem very effective. It took a considerable distance to come to a stop. I proceeded down the hill in a lower gear and at some point the brakes returned to use. There does not appear to be any reason as to why they failed or how or why they returned. The car has over 20,000 miles on it and this was the first incident of brake failure; although the situation with the cruise not deactivating had occurred once before. The car was taken to the dealer on 11/7. the dealer checked both the cruise and the braking system and found no problems. The dealer reported consulting with Subaru on the problem as well. On 11/12 at the suggestion of the dealer, I contacted Subaru customer service (ref#1-1157948155). Subaru's follow up was that the car was checked and found to be ok and we should drive it and see if it happens again. This was not acceptable and we opted for a replacement vehicle at considerable out of pocket expense. This vehicle should not be sold to someone else. It should be returned to Subaru to determine what caused the failures described.
