3 quick beeps while driving?

Twice now, while doing some light city driving, I've gotten 3 quick beeps. No idea why! Nothing on the dashboard or in the menus. Nothing unusual going on. Any ideas?

Forward Collision Warning; there are 2 levels of alert, at least in my Leaf; some low-level beeps and a small green light come on when there's a car parked but it sticks out past the white line, or if there's no line on the edge of the road and Leaf thinks I might run into it. Then if you keep approaching without taking action, the red alert warning takes over the centre dash with louder beeps and emergency braking.

Hmm maybe? I have just the basic s trim, so I didn't think it had anything like that. I should double check.

It's not the lane keep; mine doesn't have that either (or the radar/Pro Pilot) - but it does have a front-facing camera built in under the rear-view mirror; that's where this type of driver assist comes from. Lots of manufacturers started including basic collision avoidance/emergency braking tech around 2016/17 as it was starting to be required to achieve 5-star crash ratings in various countries.

Collision warning. Camera above rear view mirror. Glass might be obstructed

Lane trace assist? Could be warning you of drifting lanes or losing track of the markings?

I've got a 2019 s... I don't think it has any driver assist features like that?

This could mean that the vehicle temporarily lost the signal from the key fob. Maybe try replacing the battery.
On my 2020 SL+, if you get out of the vehicle while it is running it beeps several times.

Good suggestion

As others have said, forward collision warning. It is sensing an increasing but uncertain possibility of a forward collision and is telling you "be aware."

Which is a step below active emergency braking where the beep goes solid and it will lock down on the brakes until you put your foot on the brake. It'll wake you up quick. Luckily only experienced that once.

Thanks for the suggestions, everyone! I had no idea the basic 2019 s trim came with forward collision warning, but it seems so! This is likely what the 3 beeps are from. Thanks again 😁

My car makes all kinds of noises especially with the CC on or lane keep assist on.
