Typically the key is left in the car in the garage. Tonight at 6 pm, at a garage temperature of 83 degrees f, the engine spontaneously started. No one was in the car and it had been garaged for about 3 hours. I just happened to be in the garage when the prius started and was nothing short of flabbergasted.

My prius is using 1 quart of oil per 900 miles, the toyota dealership did a oil study and verified that indeed the car is using 1 quart per 900 miles, but will not do anything about it and stated my car is no longer under warranty and could be rebuilt for 9000 dollars-this is a commuter car only and has only been used for open road driving.
