July 2007 Prius, 79,866 miles Friday night, 70 miles from home, I stopped for gas then got back on the expressway. Going 70 mph and suddenly all the dash went crazy with lights, I noticed a decrease in power, and the screen showed the warning light of a car silhouette with an exclamation point. I pulled over to the side of the highway and caught my breath. Looked in the manual to see that I needed to call a dealer and not drive the car. It wouldn't start anyway - some lights and battery power but the same warning lights and the car would not engage in reverse or drive. Towed the car to the dealer - $250. The next day they called and eased my mind, said it was the 12v battery, to come on in because it was almost fixed. Got there and they said the test drive had not gone well, it was still having problems but it looked to be part of the hybrid system so not to worry, this was better news financially because the warranty would cover it and pay the towing fees as well. They also gave me a free loaner car which isn't common at this dealership. Today the bad news. They say they have been working with Toyota engineers to diagnose and that it is a short from the electric motor transaxle assembly that is backfeeding through the hybrid system. They need to replace the transmission transaxle assembly at a cost of over $5000 with taxes, and it isn't a hybrid component so no longer covered by the warranty because of mileage. (Still under 5 years, but over 60,000 miles). The codes: C2300; C2318; P0A78 I don't think it's worth it at all to put $5000 into this car. Summer 2010 it blew a P0420 code while I was out of state and required a new catalytic converter, luckily under warranty. I've maintained the car regularly and always through the dealer. Pretty down on Prius and Toyota right now. Also, what's up with California and other states getting longer warranties? Should I fix it or put the money into a different vehicle?
