Charging Noise - Normal or Nah?

[allonwatson]

So I've got a Niro EV, and there's this strange hissing noise coming from under the hood whenever I'm charging it. It's more pronounced on Level 2, but I can still hear it on Level 1. Didn't notice this at all when I first got the car, so I'm kinda freaking out. Is this just a normal EV charging noise, or should I be worried that my car’s about to turn into a hissing pressure cooker? Got any tips or advice? Thanks a ton!

Do you smell anything unusual? I'd recommend letting your dealer listen to it.
