Anyone noticing that on the 2007 hybrid model, the assist mode works very inconsistently? I noticed unless i really step on it i dont see it assisting at all. And sometimes it assists fine, but it seems at low speeds where i really need it its not assisting, or it will start and then stop. For example after i get to about 30 the eco light will come on and the assist bar will start lighting up and then i feel a shudder and the eco light and assist bar dissapear. Should it be assisting me more? Also every so often i'm getting a hard shudder and i dont know if its the transmission or the car not being able to decide what mode it needs to be in. PLEASE anyone that has input on this or has peace of mind for me that would be great!
Thanks in advance

Joe
