My New Rx400H

Do Prius owners have this problem after leaving thier cars unattended for a few weeks? Or even GS300H owners?

Prius gen II suffers the same to a certain degree, that has a very small Battery which seems to fail after about 5 years. They don't have the same power draw when first trying to start from the auto lights coming on or the steering wheel moving when the key is inserted so even if the Battery is almost flat you have more chance to get the system 'Ready'.

In that case you would think the priority in the RX would be to get the engine running first THEN move all the "nice to have" gubbins on its way before the vehicle lets us get on our way.

Too simple for a software engineer to work out I guess?

When I bought my 2005 I insisted the dealer test and, if necessary, replace the 12V Battery. They found it to be at the latter stages of its life and put a new one in.

I'd recommend anyone else do the same tbh. They're not expensive.
