I bought my car 08/31/17. When I turn off the car and open the door I get a warning sound that my lights are on. Nice feature and I have been turning my lights off every time. I was changing out the dim weak halogen headlamps to LED replacements. Every thing was going well and they worked very well, but as I was admiring them, car off door closed, all the exterior lights shut down! I thought to myself that for some reason I had blown a fuse. After checking, I found that the car's exterior lighting will shut down after a short amount of time on their own. When you get back in the car and start it, they come on again. Didn't realize it had this feature because of the lights on warning sound when I opened the door. I checked the owner's manual, but could not find any reference to this feature. Anyone else noticed this feature?
