Siena:
May I ask what's wrong with your current engine? Because the Atkinson Cycle engine seldom goes bad, at least not to the point of requiring a complete replacement.
I work for a Toyota dealership, and have NEVER replaced a Hybrid engine, in whole or part.

Hi @Siena and others. Please do u know how much i can replace a hybrid battery. I was told some cells are dead in my toyota camry 2007 hybrid high volt battery and that's really making the car go off from time to time.. Please help
