Two things here. One is when using adaptive cruise control; when there is a car in front that is going slower than your speed your car will slow down. But when it goes out of the way the car will just rev up as much as it can and just catch up to speed. My Camry before this had two options of speeding up; one slower than the other so it saves the transmission. Also, my engine would randomly be at higher rpm-??s than usual when at park. It would idle higher than go lower than back and forth. I-??ve experienced it during cruise control when randomly my engine would be revving up and down; car being a little jerky. I-??ve read online that Mazda is known for transmission issues with also their transmission sensors. Something needs to be done ASAP and fix the issue
