I have a 2010 Prius 10,100 miles, no problem history. I return to the airport parking garage today and the car is dead, not a peep or tweek. Pull out the manual and follow the special jump-changing instructions. Nothing, not a peep. Call the Toyota dealer and the service guy first says I won't be able to get in to that car because I don't have a mechanical key. Fortunately the tow truck driver explains it's inside the electronic fob. Get the door open but no response from all the charging we're done, not a single beeb. When I tell this to the service rep, he says "You're going to have to have it towed it. AND BY THE WAY, THIS IS VERY COMMON ON PRIUSES. IF THEY'RE NOT DRIVEN FOR FIX OR SIX DAYS, THEIR BATTERIES GO TOTALLY DEAD AND CAN'T BE JUMPED. Has anyone ever hear of or experienced anything like this? Right now my Prius is in the shop.
