The engine shutoff while my wife was driving this car in traffic. The resulting problem was a failed crankshaft position sensor. This failure shut the engine off and the car was without power to pull to the side of the road. Had she been making a left turn in front of oncoming traffic, this could have resulted in a major multiple car accident. My question to Subaru (given they like to tout their automobiles' safety record) is why would any engine sensor failure leave the car without power? isn't this the same as the infamous gm ignition switch tragedy? since the sensor was replaced, my wife is afraid to drive the car for understandable reasons.
