What you describe sounds like a charging system failure. If the alternator isn’t working, the car can run on the battery for a period of time, until the battery voltage gets below a certain point, usually around 10.5 volts. After that the electronics will start to go haywire. Your battery is probably marginal as well, as the car would usually operate for a couple of hours without the alternator charging before it starts to fail. I can’t account for the sounds you have described, but I think checking the battery and charging system is in order. You can Contact Your Mechanic to have a qualified technician come to your home or office and check out your car and tell you what needs to be done.
