We have a 23' Nissan Rogue, it also will feel like it shifts gears sometimes, but it's a CVT, yesterday, it didn't feel like it shifted at all. I tend to notice it when I pull out, to the right, onto a state road, Rt32, which is a slight uphill to accelerate, to get up to speed before traffic coming up the hill from my left. I made note yesterday, that with no traffic coming from the left the car just feel like a CVT. I guess it may depend on how much throttle you give it, along with other things the car senses.
I'll add, the Rogue's engine is not as quiet as the 3.6R or the XT's when accelerating.
