The component / system that fails is the fuel system / fuel pump. The 2016 subaru impreza has the same fuel pump that later motels have and they where recalled due to the fuel not being delivered correctly from the fuel tank to the engine. it is typically winter fuels that make the fuel pump fail. (there is a handful of information on other websites) The safety issue is that the car will shut off and is difficult to get started again. this happens when the car has about 2 gallons left in the tank or 50 ish miles to empty. this situation has happened to me three (3) times on the highway at about 70 miles an hour. this also happens most commonly in the winter due to the available fuel. this is also a safety issue because the car has NO heat and you could be stranded with a baby and this could become life threatening. This problem has been reported on other websites and reproduced in my car 3 times. When I got my car towed to a Kia dealer (closest one) they said it was a mechanical issue with the fuel system. The Kia dealer told me that the issue is due to winter fuel and low pressure in the fuel line. they recommended that I keep my car at or above 100 miles to empty. (so far they are correct) This issue doesn't trigger any warning lamps / lights, or set any codes off. The car will just shut off and you will have to get more pressure into the fuel system.

Vehicle was stationary. Car died when starting. The starter turned over and the engine engaged, but immediately died. There was no forewarning concerning the health of the engine (I.e. No check engine light, no rough riding/issues with gears). My mechanic checked inside the fuel pump and saw there was a wire burned black that caused the fuel pump to fail. We are very concerned that this is a fault of equipment and not simple wear and tear on the car.
