Numerous warning lights indicate the computers for those systems are turning off, and to have so many do that at the same time is commonly caused by low system voltage. Start by having the charging system tested with a professional load tester, not the quick tester they use at auto parts stores. In particular, I would like to see "full-load output current", "charging voltage", and "ripple voltage".
