I went shopping. I returned to my car tried to start it and nothing happended (no sound no nothing). Since this had happened to me once before I know what to try. I popped the hood, removed all the "black" relay fuses. I let them sit for about 1 minute and then reinstalled them. The car started right up. I don't know what causes this problem but it is horrible. The first time this happended I thought the alarm malfunctioned. I was stuck for hours trying to figure it out before I called the tow truck. I had the car towed home and tried everything. (I am a troubleshooter.) I realized that once I removed and replaced the fuses that it started. I made a note of it just in case it happened again. Wow this is horrible. If you have no clue the dealer will charge you a fortune. I will never purchase another dodge vehicle.
