You will need to have a thorough inspection of the battery and charging system by someone who is experienced in testing for poor wiring and wiring connectors. If you have poor connections at a wire terminal, you will see these types of problems, however you cannot see these, they need to be diagnosed with a Digital Volt Meter. Start with the battery cables and the charging circuit, then work your way up to the dash warning light/message circuits.
