Did you report this incident to the dealer? That's Nissan's (and all manufacturers) primary path to get feedback from customers. Dealers are charged with reporting the issues that they find and that their customers report so that the appropriate technical people can determine what's happening in the field.

I agree though...it sounds like in turning off the vehicle it may have been accidently turned back on again (one too many taps on button), which then meant the lights would continue to go on automatically. Though the car automatically protects the High Voltage battery from going too low, it can't help the 12V battery. And it needs a minimum voltage from the 12V battery to activate all the relays in the High Voltage battery to start it!

And by the way, this same thing happens in other I-key cars too. My friend accidently left the car running for two weeks in his carport while he was away. In another instance, he inadvertently kept the the key in his pocket when his wife dropped him off at the airport...and she drove away. Fortunately, the spare was at home, and she just went home without turning off the car. I-key will allow you to lock the car or just walk away with it turned on in any position (on or in ready), although it will beep at you. In some senses it seems like it shouldn't do that--but if you think about it, it kind of makes sense that's the case--because what if you wanted to leave your car running while you went back inside somewhere? How else could you do it? On the bright side, i-key saves us from ever locking the keys in the car.

For recharging the car if the main battery is low...it has to be in any gear except Neutral (as mentioned above). If it is in Drive, it will recharge also, but do so with your foot on the regular brake pedal...not the park brake. If your brake pedal is pushed, the car automatically cuts driving torque and redirects power to the generator through the planetary gear. If you use the parking brake, the torque just works against the parking brake. It will still get there this way...it seems like it would take a lot longer!


Oh...for power windows. That only works on the down. It doesn't do it going up...for safety reasons I've been told. (Keeps people from doing stupid things, like squeezing people in the window or trying to explode soda cans inward? Who knows.)
