While driving home my alarm system light blinked on then stayed on. The headlights shut off and turned on. After I parked the car and turned off the engine the theft deterrent system activated and my car would not start for 45 mins. I followed all reset procedures nothing worked. Had to disconnect and reconnect alarm. Now alarm will not work and the trunk/doors open or unlock randomly, radio turns off, lights turn off. Problem has been happening for a few weeks now noone in town knows how to fix.
