I feel for you. Had the exact prob... Well sort of. Lol I have a dodge 2007. Its battery light came on, we replaced the battery. A day later we broke down at 930 pm a mile from home. Got it towed. Assumed it was the alternator. Replaced that and its core. A week later broke down twenty yards from home on the same time. Battery was dead. Went to the place I bought the battery. It should have been reading at 525 volts or whatever and it read 420. They said it was still "ok"... I called my uncle. He called them, and ten min later I had a new battery... Battery light came pn a week later... Broke down at my aunts house. Towed it to the dealership. Needed to have all the electrical cords replaced...

I am ready to burn this car and get the insurance money... I really am... Lol but I hope you get home alright soon!
