 These hybrid are in the baby stages, there are a lot of serious problems with the hybrid system components, these vehicles are death traps, they can stall on you and shut down without any warning doing 70 mph, no power, no steering, no brakes almost got killed by a semi on the freeway. I'm talking to a lawyer, it's happening to others in other states, they are very expensive to fix, 14,000 dollars that's what my dealer wants to fix, they are nuts a four year old car, needing such expensive repairs, my last hybrid, or Toyota, and yes they say they are warrantied, but a warranty is only good if they will fix it and Toyota won't.
