So, I'm hoping you all can help me diagnose my Liberty issue. I had slow starting problem, so I replaced the battery yesterday morning. (The battery was 3 years old and in the desert that a long time.) After, it started right up no problem. I drove 15 miles to campus, both freeway and surface streets in traffic, no problem. On the return trip, after I got off the freeway, I pulled up to a red light. When green popped up and I hit the gas... nothing. The car had quietly died. No sputter. Just dead. The only light on was the oil symbol. I put it park, started it. And got home without issue. No CEL. Later, same day, made another 15 mile trip. After I got off the freeway, I went a few miles. Hit a red light (not the first one, maybe the 3rd) car quietly dies. Same thing. Green light, I hit the gas... nothing. I restart and get to my destination no problem. Again, the only thing I see while the car is dead is oil symbol. During both these drives I have the A/C running. And after the battery replacement when I had the car running with the hood up I noticed that the A/C compressor was making a little noise when the pulley engaged. The A/C compressor is only 5 years old. Could the belt be slipping and cause the car to quietly die? When the car is running, no problems, no lights, no rough idle. Info: Liberty 2006, gas, 120k (30 of those towed behind RV) mechanically awesome, dry no leaks. It's, well, perfect and the love of my life. HELP!
