Car Slowed Down On Its Own Problems of Honda Civic Hybrid

I'm concerned with the safety of my family when driving this vehicle due to the poor performance as detailed below. The ima battery drains so frequently and so suddenly(gets worse in the summer) that we've been very close to be involved in a few accidents. When stopped and waiting at an intersection for the green light, the car is either idled or in "auto stop" mode. Once the light turns green and I let go off the break, the car fails to accelerate fast enough to the point that I don’t make it across the intersection in time, even though I'm the first car closest to the intersection, thus causing the cars behind me to run the red light. I have also had very close calls when merging and entering the freeway at the speed of traffic since the car fails to accelerate. Another dangerous situation is when driving on the freeway at a steady speed of 65 mph on flat conditions and coming to an uphill, the car doesn't maintain the same speed. So I need to accelerate more. The rpm reaches 4000, the car is now barely making 45-50 mph and the traffic behind me is force to slow down or suddenly change lanes in order to avoid hitting me from behind.
