Narrative:

As we were climbing to 17;000 feet after taking off out of ZZZ we received multiple crew alerting system (cas) messages as well as red indications. We immediately [advised ATC] and were given a turn back to ZZZ. Based on the messages received; plan a would be to use ZZZ versus plan B; ZZZ1. During descent back toward ZZZ; a few miles from the airport; and around 3;000 feet; cas messages started disappearing. As the pfd started looking normal; due to the disappearing cas messages; we decided that plan a was going to be our first option. Although we had 3 green; indicating our landing gear was down and locked; due to an initial red cas of lg lever disag; we requested to do a low approach to have tower confirm our gear appeared to be down. After assessing the situation and reviewing checklist items in the poh and in our company checklist; we made a safe landing at ZZZ.
