If anyone on here feels their brakes are "grabby" do you mean:

1. That you don't like the amount of deceleration the car does for the amount you step on the brake?

2. Or do you feel inconsistent braking (almost like pulsing) during a stop, could be during the beginning middle or end.    

Generally, most reviews say they are grabby because I feel if you move the brake pedal very little, the car decelerates a lot.  If you switch back and forth between a hybrid and regular gas car you will notice it more.  

Regen does not work in reverse or in neutral.  The friction brakes are actuated in these events.  You can easily show this by shifting into neutral while doing a full regen stop.  You'll feel a slight jolt as the regen comes out and the friction comes in.  

Never heard of this happening.  Most likely it is a powertrain issue.  

It could be a loose motor mount.  They engines do flex a significant amount under load.
