Ive noticed that when it is incredibly hot outside (95 & up) my Hybrid takes a while to engage the battery mode. And on top of that if im cranking the a/c itll and the vehicle is stopped, it will almost like bog down when I push the accelerator to go. Not only that, but it wont even go to battery mode when I am stopped. It actually quite scary bc as I push the accelerator I have no idea what its going to do... Im going to take it in to the dealership, but I was just curious if anyone else has experienced these problems.
