What is result of leaving car "ready to drive" overnight?

Fri Jun 30, 2017 6:11 am

Several times, I've got out of the car and noticed only at the last second that I had not hit the power button after the Park button. Last night I went out for a quick last-minute trip to the grocery store and found the car was still "on." It had been sitting in the driveway for about three hours, I think. Climate control was only fan on a lowish setting, no heat or AC.

If you leave the car on overnight, how big a drain is it? Does the car EVER shut off automatically if you forget to hit the power button and walk away?

I happened to charge to almost 95% at work yesterday, so we had range to burn. Not really sure how much, if any, the GOM had counted down during those three hours.

Frankly, I'd rather have a mechanical key than a wireless key. I guess I'm old and crotchety!

why should it shut off automatically? No other car does this. Headlights are one thing but they ONLY shut off if the car is not in run mode.

As far as your question; a little drain on the battery which your EVSE will easily overcome and a very very low average speed.

Get into the habit of locking your doors when you leave the car, then it will tell you that you've left it running.

does it work at long traffic lights? Bridge crossings? That would be a reason for me to never buy that car (as if I needed a reason)

I run into this when I stop at my townhouse development's mailbox cluster to retrieve my mail. Since I've opened the door and it stops sensing the key inside (since my mailbox key is attached to the fob) it knows the driver is no longer inside and shuts the car off. Sometimes, if I re-enter the car quickly enough, and fasten the seatbelt, it will resume again, but that's not consistent.

As far as cars shutting off at traffic lights, don't rent a car in Europe, because automatic start/stop is becoming more common over there. It might even be mandated for newer cars now.

One feature of the Leaf that I miss on the eGolf is the automatic "Park" feature when you turn off the car when it's already stationary. I got so used to it that when I'd rent an ICEV with pushbutton ignition I would forget to put the shifter in Park before turning off the car, and it would take me a few minutes to figure out why the car wouldn't turn off (though the engine would).

Perhaps the OP can do that to prevent him/her from inadvertently leaving the car powered on.

You don't have to do that either. Your car beeps when you open the door in run mode.

I NEVER put my Leaf into park. Like our Prius I simply push the power button to turn the car OFF and put it park.
The only way to lock the Leaf with the car running is to push the outside button or remote. Pushing the inside lock button after the door is opened will result in it unlocking itself as soon as you close the door. Guess they are trying to prevent locking the FOB in the car.

@OP The drain on the battery should be relatively low. I seem to remember someone saying the drain was around 400-450W at idle. That's very little compared to the 22-33kWh contained in the traction battery. Three hours of idle would have likely dropped the battery a percent or two.

Many times I eat lunch in my car and I just leave it "running" so I can easily put my windows up. I rarely notice any drop in percentage for a 30 minute lunch.
