Default 300H Car Rumbles at Start

Hello all,

New ES300H owner here. I have a question when it comes to how quickly you can start the vehicle. When I start the car, you hear the engine kick in, I have automatic eBrake on, so you hear a noise, of what I think is the brake being released. I wait until that takes place before switching to Drive, or Reverse, but sometimes when I do, I hear and feel a rumble in the car. Is this normal for this to be happening? Do the Hybrid systems need warm up times before switching into gear? I want to make sure I'm not messing anything transmission wise.

Would have to hear it to know if it's normal. The hybrid makes a lot of noises that regular vehicles don't.

The ES300h gas engine can rumble and jerk/shake the car at times. Yes it's normal. I had two ESh. Both did this. My CT200h did this as well as my Prius. It's the nature of the hybrid system. Normally the engine is off while the car is stationary, but should the conditions be just right to where the car requires the engine to be on, you will feel the rumble/shaking. Sometimes more shaky than others. Usually you won't feel this though as the car is at speed, driving in most of those cases. You just notice it most when the car is stationary.
