How is this relevant to the situation being discussed? Do you think OP pulled into the airport parking, turned off the engine, and bumped tunes for an hour before going to the terminal???

I used to do this to relax for a few minutes before work or whenever, killed a couple of batteries.

Most likely this is the issue. The car keeps the key module on looking for the key fob. It’s a small amount of power but over many days could drain the battery. Car batteries go dead in airport lots all the time.

Keep driving and see if you have any more issues in normal usage.


Wow, I already think the keyless technology is stupid and pointless but this takes the cake.


It is particularly bad with the Prius because it has a small battery but can happen to any car.


Doesn't the Prius have a big battery because it is a semi-electric car?


Yes it has a big battery for big power things but it also has a small 12V battery for normal car electrical things (lights, radio, keyless entry, etc...)

Make sure your brake light is not sticking when you get out of the car. That switch can go bad or stick, leaving the brake light on and draining the battery.

Your car was possessed.

FWIW, OP, I just had to replace an alternator in my RAV4 that also killed an otherwise healthy battery, pretty much overnight! (Battery had just been tested a few weeks ago.)

The telltale sign that something was wrong was a "woooo, woooo, woooo" ghostly sound when I started the car.

This. The alternator needs to recharge the battery. Also, only driving short one mile trips will ruin your exhaust.


OP here, my commute each way is over a half hour. No signs of a problem until I parked it at the airport for a week. It was hot, but even so, it was in a parking garage undercover.


It takes you 30 minutes to drive one mile??

Can you walk, bus, bike, scooter? Why would you drive that distance?


OP again. That poster isn’t me. My commute is 36 miles in the mornings.
