My guess is that they expected considerable battery drain to occur in the long transit from Japan.

Interesting.
My brother just called me. He came home after 6 days to his 1 month old 2010 and it too was dead.
Can't get into the trunk to jump the aux battery as there is no key and absolutely no power.
Toyota sending a flat bed to take it to the shop.

This is not a very friendly car under a battery dead situation.

Should be able to get into the car with the mechanical key, open the hood and jump start it from the connection there. Owner's manual pages 541 and 543 through 545.

We just returned from a long (21 day) trip, and had no problem starting our Prius IV. The car was unlocked, in the garage.

Geez, tell your brother to read the manual. As previously stated, you can get in with the key in the remote, then pop the hood and jump from there. It's not rocket science.

After reading all these posts I just made sure that my handy jumper cables are in the storage compartment in the back. Heck, growing up I had cars that had to be jump started if they sat more than a day! The Prius is so easy to jump, not even an issue to me. I taught my wife how to jump a car and change a tire as part of our marital contract. Taught her how to jump the Prius and made her practice. She could now care less if it goes dead either. Empowerment!

I left mine in the driveway for 2 weeks while traveling, no issue. Car was locked, solar roof was operational (this takes some additional juice for the ECU and there's no charging from roof to 12V). No issue. Also left it @ the airport for 9 days in similar conditions. Also no issue when returning. In neither case was the spare FOB anywhere nearby.

Have them give you the service bulletin and please scan it and put it here in the forums. Otherwise, I'll say that your dealer is lying. There are no instructions to shut things down in the manual, though it specifically mentions that all lights are shut off after 30 minutes and the SKS shuts off after 3 days. (Did you leave your key in the car?)

Many of us have left our 2010's for longer than that with no problem.

Amen and how many times must this be stated in 2 threads? Alas, a small number of people report the problem and the fear. What are they doing that the rest of us have avoided so far?
