I would make sure to schedule it.. I can say with the 3 Toyota hybrids we have owned the transition is pretty much, except for the audible sound, smooth with no real feal
of any vibration at all. This would be on a '21 Venza, '20 Rav4 hybrid, and a '23 Cross hybrid.
It's not normal to me and would take advantage of the powertrain warranty and fight for it to get corrected. Service may claim it's normal because it could be potentially labor intensive. Good luck and please update.

 

I can feel the transition on my '21 but it's pretty smooth

I've settled into 44.8 mpg indicated after 2.5 years and ~12K miles under ideal conditions.

46 is really good. I'd have to drive ultra-conservatively to achieve that. Not even sure I could.

I'd call mine smooth as well, I'm probably just being sensitive because of the below avg MPG from the prior owner.

The engine is honestly amazing. Had a good bit of weight packed in the other day for some hilly highway driving and wasn't cautious on the accelerator. It handled with ease!

 

I hope you paid a fair price since used Toyotas are very overpriced right now

 

So I wonder if it’s because your old hybrid didn’t have port injection and direct injection. This engine has both so even at idle, the engine will not sound the same when it switches.

 

If yours is a '23 they do seem more pronouced when transitioning between ICE and EV. I've had a '21 and a '23. '21 was much smoother.
