Not like it's in front of the car so it can get punctured by a rock. Made of aluminum and located inside the car so won't rust. Are late model Subarus known for leaking evaporators? Pretty much diagnosed it as the source of the leak in my '16. It was blowing cold last fall but nothing now. Compressor engages but low pressure on the test gauges. Recharged and air is ice cold. Used an electronic leak tester and got nothing along the lines under the hood, but as soon as put it to a dash vent, it goes off.
