I think you might not be noticing it because it's very subtle. I only noticed it (changing from regenerative braking to friction braking) the other day after owning the car for 5 months.
It's not that much of a change and certainly nothing worth worrying about.
As long as the car stops, you should be okay.
If it doesn't stop, then you got something to worry about.

You've just discovered Pulse and Glide! Removing your foot from the accell pedal will immediately activate regen braking...not alot, but some. Then if you gently (I mean, VERY gently) depress the brake pedal, you will be in the coast mode or glide or whatever you may call it when no arrows are showing on the screen. Do all Cam Hybrids have the screen that shows the energy flowing from/to the various hybrid parts? Sorry if you don't have the screen, this explanation will be slighly less helpful. Anyway in this mode there is no regen drag to slow you, nor any motive force from the electric motorto move you forward...and you speed up if you are on a slight decline (or even on flat roads).

This is the most efficient part of HSD, as it truly is a "let momemtum and gravity keep you moving" mode.

That accell pedal is the controller for all this. Different positions during certain conditions will seem like the car lurched forward when in fact you (with the car's computers helping) put the car into the glide mode when none of the drive train is engaged...soap-box derby mode!

I can't say that I've noticed this "problem." The cruise control is supposed to disengage as soon as the stop-light switch is activated. This should take only a few millimeters of pedal travel. (At night you can check this by looking in your rear-view mirror. You can see the reflection of the high-mount stop-light LEDs on the rear window glass.) Mine does this. If yours doesn't behave this way, a warranty adjustment may be in order.

P.S. I've just seen finman's post. I think he's got part of the explanation! When you disengage cruise control by using a tap on the brake pedal, since your foot is off the accelerator pedal, the car will begin coasting under mild regenerative braking, which will cause a small deceleration lurch. You can control the extent of the lurch, and whether it's forwards or backwards, by first feathering the accelerator pedal (2-footed driving); or better (1-footed) by using the steering-wheel lever to disengage the cruise control, after first feathering the accelerator.

I had this happen again yesterday and sure enough it was as I hit a small bump in the road while applying the brake. This spring there are a lot of 'bumps' in the road here in the upper midwest due to the nasty winter this year so that is likely why I'm experiencing this more frequently than most. This isn't dangerous, the car brakes, just a weird 'feeling'.

Yes, it can be very subtle at times. Sometimes I only notice it by sound alone; the regen whine suddenly disappears after a little bump. I usually quickly lift and reapply the brakes to recover the regen whine
(I hate friction braking )

Two climate control systems, one inside and the other at the tailpipe.
