I bought a 2019 Niro EV a couple weeks ago. I've noticed that after I turn the heat on to warm the car up, then turn the climate system completely OFF, I can feel cold air coming through the dashboard vents and floor vents. I have to physically close the dash vents, and then i can feel the air a little stronger at the floor vents. I've only noticed this once or twice, because I've only used the car at night when it was cold enough to use the heat once or twice. So I haven't really had enough chances to try to troubleshoot it while its happening. I don't think I've ever noticed it happen other times, when I haven't activated the climate system at all. The climate here is mild so I usually don't run it. Any one have any ideas?
