Check battery for condition first including load test. Then check headlight fuses and relays in underhood fusebox. Have a pro scan for codes for door locks and window a module may have gone out as well. If the power steering is electronic then have that scanned aswell if not have your belt checked, replacement for a belt and tensioner is 60k recommended, it may be slipping causing a lot of your problems.
