I guess while I'm at it I might as well tell about the small thing when driving.
Sometimes if I'm going fast, but have to slow down really fast and then take off again there seems to be hesitation for about 1 or 2 seconds then a sudden jolt off. Not sure if that's normal or not. This is the first car I've actually owned so Idk if I'm just being paranoid or not.

Yaris's do that when you start to activate the high rpm functions of VVT-i, it has to do with how VVTI fuctions in the car under load. Mines done it since brand new and I've got almost 100k on the clock and I race the car.

I'm also guessing you have an automatic which again that behavior is normal. When you brake or let off the gas the torque converter disengages and lets the motor freewheel but when you press the gas the converter grabs again which causes that jolt all automatic transmissions do that at least from my experience.

No need to worry both of what your seeing happen is normal.
