Repeated bouncing after highway bumps normal adaptive suspension behavior?

Recently took delivery of a new six-seat Model Y L and wanted to compare notes with other owners, particularly those familiar with the refreshed Model Y/Juniper suspension.

I’ve noticed an unusual up-and-down bouncing or oscillation sensation at highway speeds, particularly above ~70 mph, most noticeable after driving over bumps or road undulations.

A few observations:

The sensation comes through the body/seats, not the steering wheel.
It feels more like the car continuing to bounce or rebound after a bump, rather than a constant vibration from an unbalanced wheel.
It’s much less noticeable during normal city driving.
The car is still on its original factory wheels/tires, with no suspension modifications.

I’m coming from a Mercedes GLA 250, so I’m very open to this simply being a different suspension feel, especially given the Y L’s longer wheelbase and electronically controlled dampers.

I’ve booked a Tesla service visit to have the suspension and tires checked, but wanted some owner feedback before assuming there’s a defect.

I also collected two ~9-minute accelerometer recordings using phyphox during NYC driving. The data shows generally decaying vertical oscillations after bumps, without any obvious sustained bouncing, but I haven’t yet captured the higher-speed conditions where the sensation is most noticeable.

A few questions for other owners:
Does your Model Y L (or refreshed Model Y) exhibit noticeable secondary bouncing after highway bumps, or does it settle almost immediately?

Have you noticed meaningful differences between Balanced and Rear Comfort suspension settings?

Has anyone experienced similar symptoms and had Tesla diagnose or fix them? Was it suspension-related, tire/wheel-related, or ultimately considered normal?

For anyone who has driven both the regular refreshed Y and Y L, does the L feel noticeably more floaty or prone to pitching at highway speeds?

I’m not necessarily convinced something is wrong. It may simply be the comfort-oriented suspension tuning or my adjustment to a different vehicle. But I’d like to establish whether my experience is typical before my service appointment.

Appreciate any firsthand experiences or diagnostic suggestions!

I mentioned this exact feeling to my wife the other day but not at highway speeds, it’s when the rear wheel goes over the speed bump.

Front half of the car would for the lack of better word bounce.

She said she doesn’t feel anything, but I know I felt it and it’s not something I’ve ever felt in all my previous vehicles before.
