Every car I've ever owned before had electrical accessory outlets (cigarette lighter outlets) that were depowered when the car was turned off. I bought this Fusion Hybrid Titanium almost 3 weeks ago and just discovered that the electrical accessory outlets remain powered when this car is off.
The reason I noticed it is that I have an ionic air purifier that I like to keep in my car. I had it plugged into the cigarette lighter outlet in my previous car (Hyundai Sonata) and I transferred it to my new Fusion from day one. I just noticed this morning as I walked up to the car (it had been off overnight) that the blue light on the air purifier was on before I got in. That got me into the owner's manual, where I found out that you're not supposed to leave anything plugged into these outlets when the car is off. I took the air purifier out today and will not be using it anymore.
Here's my question. Do you folks think that 3 weeks of having this (fairly low) draw on the battery over night (each night) has had any adverse effect on the battery or on any other components of the car?
