Friend of mine wholesaled his Ferrari FF because of repeated electrical faults. Ferrari North America would not authorize battery replacement for quite some time before the mechanic just decided to do it. Fixed all the issues but that was far too late for this new Ferrari customer. Bad tastes last a long time.
One tidbit about modern engines with stop/start systems: these are programmed to stop operating when battery voltage drops below a certain point. Since the software continuously monitors the main service battery during periods of engine stop battery faults can be detected very easily and early. The alternator also stops of course allowing for very accurate battery drain rate inputs into the stop start software. First thing to check if the stop start system doesn't operate reliably is the main service battery.
