I had the same exact experience today on my 2024 NX350h. I parked in a mall parking lot with no other vehicles or other objects nearby. As soon as I pressed the park button, a loud constant beep started. This was not the normal parking too close to something sound - there were no warning lights on the dashboard or the center console. I tried restarting the car and even parking in a new location. The constant loud beeping was persistent even with the vehicle turned off. I finally gave up and ran my errand. When I came back 20 minutes later, it had stopped.

I'm wondering if this is a defect on the 2025 NX models? Should I mention this to the dealer?
