With low voltage starting and power on reset, radio in my 2012 was the very first thing to act up, ain't a radio, but a computer. And why they are using flashram in these things is well beyond my degree of comprehension, but also can be a problem if the code was corrupted. PROM would not have this problem. If let go, problems increase to getting codes, namely from the BCM, the ECU seems to be the most solid, but if that is left unattended, engine won't start. Ha, when mine got this bad, I did manage to start it, by removing the key, opening the driver's door, did start on the third try, was 40 miles from home, time to do something. Switched on the blower to full speed, 20 amp load, engine off, got my VOM and checked for voltage drops, both negative and positive battery cables were bad, dropping a total of around 2.1 volts. Drilled out the crimps on the battery terminals, copper on the inside was corroded and bare, soldered those in. With my scope on the output of the ignition relay, not a clean pulse, jagged, so popper off the cover and cleaned the contacts. This ended all these problems, replaced that made in China ignition relay with a Panasonic.
