I was driving yesterday and my engine stalled and then all the dashboard lights went completely out.
From what I have seen at my dealership, people with similar problems like all electronics randomly shut off or many electronics shut off randomly. In these cases you would be lucky if it is a bad battery, could also be the alternator not putting out current and the battery draining down. What this would cause would be a lack of proper voltage to the modules in your car which would cause them to shut down. But usually it is a complete failure or intermittent failure of the cem (central electronics module) this is the computer that controls all of the electronics in the car. If you plan on taking it to a dealership to have them diagnose it I would plan to be able to leave it with them for a while if it is the cem sometimes it's a quick diagnoses but other times it can take a while because cem problems can leave a list of trouble codes stored in the car, it can make many of the other modules in the car that it provides power to appear to be bad, when it's really just the cem not getting correct power to the other modules to run properly. Also wether you take to dealership or trusted mechanic or work on it yourself always remember that for whoever looks at it for this or for anything in the future, if the car is scanned and a failure trouble code comes back for any module ALLWAYS check the connectors and wires going to it for corrosion before replacing anything. Corrosion will block power and electrical signals that make modules appear to fail when all they really need is a cleaning on the pin connectors or some wiring replaced. Hope this helps and good luck.
