service engine light has been turning on. manual states may be gas cap. faulty? on 2007 Chrysler 300

we make sure gas cap is on but at times it works and at times it stays on and then it just goes off. Car has 55,000miles. and we have it serviced regularly. Noticed that after a dip or bump, this happens.
