My wife has a 2005 Prius with about 150,000 miles on it. She lost power while driving and the check engine light came on. There were still atleast 3 squares left on the fuel gauge but the battery charge was down to about zero. She called me at home from the side of the road. I jumped in my car and drove about 5 or 6 miles to where she was broke down. I was able to drive the Prius back home and the battery seemed to be charging back up until we got to within 1/4 of a block of our apt. and the charge dropped back down to zero. The next morning we tried and failed to drive the car to a mechanic. Only made it a half block when all power was lost and the master warning light came on along with other warning lights. We had the car towed and our mechanic checked it out and said the throttle went out on it and that it seems to be an ongoing problem with other Prius owners having throttle issues. He said that it will cost $830 plus labor!!!!! I hope he's being honest and not just taking us to the cleaners. Any comments? Thanks for reading.
