Cruise Control problems of the 1996 Subaru Legacy

First instance was in Dec 98, 2nd 6-21-99 cruise control stays on, cannot cancel or turn off, brakes go to the floor with no effect what so ever, have to turn the ignition key off and restart the engine in order to get out of cruise and get the brakes back (this is a little scarry when you have power steering). This was a life and death situation in traffic at highway speed on an approach to a severe turn on a exit ramp.

While stopping vehicle idled highly w/no warning. A few minutes later the husband drove because he thought his wife pushed accelerator. Again, vehicle accelerated, resulting in rear end collision w/no air bag deployment. Dealership unable to detect defect.
