Savage Hybrid replaced the hybrid battery pack in my 2007 Prius one year ago. The battery recently began showing problems indicating a bad battery, so I brought it back to them. The initial assessment was a problem with the battery pack, and other problems including the catalytic converter. They called two days later with great news the problem was only with the battery pack, and there was no charge! They could have easily charged me an additional several hundred dollars, but instead they chose honesty and integrity. My advice: Don't even think about taking your hybrid anywhere else!
