Purchased my 2008 Jk Sahara (now 112k miles) about six months ago. I've started to experience the starting issues related to the transmission safety switch, no big deal really. A more annoying problem is my headlights will turn on and doors unlock on their own. Also this will happen if I shake the key fob. While having lunch with my wife the other day, I watched this happen (keys lying on the table) three separate times. My jeep has no major upgrades or after market electronics/lighting. Anyone had this issue?
