I have a 2014 XF that has a random crackling static noise when I first get in the car. The noise sounds as if it is coming from the speakers without the car ever being started, so seems it would be related to the car sensing the key fob? Starting the car and shutting it off again will sometimes fix the issue. Seems I read that this could be a battery issue in prior forums. Has anyone experienced the same issue? All help appreciated.
