2018 Pathfinder.
I first noticed this a couple of winters ago probably around 50k and I'm at almost 110k now.
When it's below about 25f on an overnight cold-start there's what sounds almost exactly like a "laughing Hyena" coming from the engine bay and I'm worried it's the water/oil pump. It will do it for about 10 seconds and stop. 7/10 times I'd say it happens. Hoping someone on here knows what I mean and has figured it out or knows what it might be. It does not sound normal or good!
