Front Suspension Nose-Dive During Braking

Front Suspension Nose-Dive During Braking
I have a question for all RX350 and RX350h owners.
Do all RX350 vehicles exhibit a nose-dive at the end of bringing the vehicle to a stop ?
For what it's worth, I am not a heavy brake pedal person.
Picked up this RX350h July of 2023. At that time I didn't notice too much nose-dive at the end of bringing the vehicle to a stop.
Over the last 6 months I have noticed more pronounced nose-dive at the end of bringing the vehicle to a stop.
Service Writer says all RX350h exhibit a nose-dive at the end of bringing the vehicle to a stop.
Is this the same experience for everyone else ?
Appreciate all your feedback.

I agree all cars to this to some extent. I've been driving since 1970 and I am very familiar with the physics that cause the "nose-dive".
My question to the group is; Do all of your RX350 vehicles exhibit a nose-dive at the end of bringing the vehicle to a stop.

After driving today and trying to make a " nose dive" I'd say that when putting enough force to push one forward in the seat the car stays flat and just stops with no drop in front. Maybe it's the F Sport suspension.

I spent a week in an RX350h loaner. It had a lot more brake dive than the RX450h+ we own, but less than what our 2013 RX350 had. I didn't find it to have an unusual amount of dive.
Brake dive is a product of suspension geometry, suspension travel, spring rate, damping, and center of gravity. The RX450h+ seems to have less suspension travel than the 350h and has a lower center of gravity than other RXs, due to the large traction battery.

I can recall watching kirk kreifels you tube video when they got the first drive of RX prior to release in vineyard. He purposely showed how on F-sport with the dampers there was little nose dive due to computer adjusting the dampers in suspension. Lexus probably did this on F-sport due to huge brakes as well on F-sport. If I really slam on brakes it will dive a bit not normal breaking it doesn't dive down at all. AVS works well as unlike the Germans it isn't as abrupt or rough, so you get the best of both worlds. Even normal driving it really smooths out the ride very well.

Coming from a 2016 BMW X5 which has much firmer suspension to a 24 Rx350h I did not notice any perceptible nose dive during the couple times where I would say I applied moderate pressure to the brakes. Cornering is of course much more body lean when compared to BMW but that is to be expected.
