I have a 15 Pat with roughly 42,000 miles on it. yesterday morning i took to the dealership to get inspected, oil change and tire rotation. I get it back around 11 and drive to work. By lunch time, (2:30) i notice that the headlights are on and that for some reason my jeep is unlocked. (habit of locking, so this is weird) I get in to drive and it worked, no problem, got me some lunch and drove for about 25 minutes then came back to work, roughly around 3:40 and parked, locked jeep and go back to work. 6 'oclock comes around and i find my jeep with headlights on and unlocked again. i go to start to drive home and them the jeep turns on, but moment i go to put in reverse, all power dies to engine and it goes into auxiliary. on the dashboard, there's this little red dot over temp gauge that is flashing on and off. lights, locks, radio all still work minus the actual engine. anyone know what this could be?
