2011 Yukon Denali - Why does the battery drain when the doors been open for a short time?
My 2011 Denali XL battery died several times after the door was left open for a short time. I had the car jumped and then the battery checked. It was fine. After the jump, the car would be fine for a long time, but if the door's left open, even for a short time, the same thing would happen. Can anyone help?
Is the key removed when this problem occurs?
The vehicle is probably designed to turn off any/all lights after about 10 minutes with a door left open and key removed after the engine is run - consider to test that: Leave the door open and read edmunds.com on your cellphone for 12 minutes, and be sure all the lights and turn off.
Also there is a setting in the vehicle for how long to leave the headlights on after the engine is stopped and key removed. It could be a minute or two. Consider to scour the manual for info about that, and maybe do the procedure to adjust the setting to reduce the amount of time it leaves the headlights on after you turn off the car.
