Hello, I have a 2018 rogue sport s. I was filling the tires up with air and I left the car running and my driver door open while doing so. As I was doing that about maybe 5-10 minutes passed and the horn beeped like the alarm was arming itself and the hazards would flash like 3 or 4 times and stop, then every so often the cycle would repeat itself. Once I got in and closed the door everything was fine, I drive home with no issues. Is that normal or should I get it checked out by the dealer? Thank you everyone.
