When running above 40 MPH and begin slowing down, hear a high pitched dinging (fast and slowing down). Service said it's regenerative braking. I disagree. That's because it occurs whether I'm using the brake pedal or letting it slow down on its own. And, the noise is really irritating, especially i9n city driving where there is much start/stop conditions. On the road (i.e. Interstates, it's very quiet.

Took salesman for a ride, and he admitted he'd never noticed this dinging.

Model is 2025, NX 350 H.

Love the vehicle. Nicest I've ever owned.
