I have a 2013 jeep sahara....I am having issues with the radio, dome lights do not turn off when the key is out and door is open. I also have a issue with the auto locks do not automatic lock after going 15 mph. This is a intermittent problem....took to dealership and it stopped when I pulled into the parking lot...they could not find anything wrong....can anybody give me any advice...thanks
