I get occasionally hissing noises, like there's an over-pressurization and a pressure valve is blowing off. But it happens on cold mornings at least as often as hot afternoons so I have no idea. I bet I've heard it pop off at least 50 times, and it still functions completely normal so I don't know what it is. Never happened over 5 years on my '15.
