Prius starting problem! Help!

[lp2]

I brought a Prius in March 2007. I have been happy with the car. Lately it started to have intermittent starting problem.

On 1/21/2008, the car completely refused to start. Here is a video I took that day when I tried to start the car: http://picasaweb.google.com/achan25/...59270888116754

Eventually I have to call a towing company to tow my car to the dealer. The tow guy jump started the car.
The dealer found nothing wrong with it, give the car back to me and charged me for the towing service.

Dealer claims it's not a battery issue since they load checked the aux battery.

What should I do next? Help!

if your not driving it for more the 3-4 days be sure to turn off the auto key function at the bottom of the steering colum left button this will help the aux battery stay charged longer. for winter storage or a long trip you should pull the radio fuse from the under the hood fuse box to stop all draw on the aux battery. the other thing weve seen is the light for the cargo area can be switched on and forgotten about because you can't see it with the hatch closed.
